Editor's Note: Engineering and technology enterprises must improve their core competitiveness and advance into the high-end market. The key is to have their own high-end technical equipment, and the core is to enhance their independent research and development capabilities.

Great Wall Drilling completed the development of three specifications of LWD and Drilling Azimuth Resistivity Logging Tools in less than 4 years. What is the R&D model? How to solve technical and management problems during the R&D process? How is the team trained? This issue of News Insight will answer these questions.

On October 31, a horizontal well in the Du 813 block of the Liaohe Oilfield is about to drill into the oil layer. Zhang Meijun, the engineer who got the tool downhole command, took the apprentice to the well team construction personnel and hoisted the drill-like instrument to the drill floor. The power-on test, the connection instrument, the tight buckle, and the downhole, a series of actions in one go.

An hour later, the drilling technician said: "The well angle, azimuth, and tool face angle can be seen directly, making the trajectory control easier." Zhang Meijun pointed to the trajectory of the drill bit on the screen and said: "There is With this equipment, the drill bit is like an eye. The oil layer drilling rate in the Liaohe oil area has increased from 76% to over 90%."

This magical tool is the magnetic field resistivity logging tool while drilling (hereinafter referred to as the azimuth resistivity while drilling). Prior to the advent of such instruments, other international measurement equipment while drilling could not accurately achieve such expected goals. At present, there are only four companies in the world that have high-end equipment with azimuth resistivity while drilling, Beck Hughes, Schlumberger, Halliburton and PetroChina's Great Wall drilling.

As one of the earliest Chinese petroleum engineering technology service enterprises to go abroad, Great Wall Drilling has thus realized the leap from long-term dependence on the supply of large international companies to independent research and development while measuring high-end equipment. The international cooperative research and development model provides an effective path for Great Wall drilling technology innovation.

Market access permits to capture internationalization

If a worker wants to do something good, he must first sharpen his tools. This is the market rule that must be observed to participate in international competition.

Since entering the Sudan market in 1997, Great Wall Drilling has not been able to break through the high-end market of horizontal well technology services, even though this technology has been matured and applied in the domestic market for many years. The reason for this is that as a high-end market – the Sudanese horizontal well market operates in strict accordance with international standards, and there is a strict set of standards for drilling while measuring equipment, technical synthesis and construction experience. Whether this threshold can be passed, high-end equipment is the key to entering the Sudanese market.

Not only in the Sudan market, but also in other high-end markets in the world, LWD equipment and technology have become an entry permit for overseas engineering and technical service bidding.

According to the data, the demand for electromagnetic wave resistivity while drilling in the domestic and foreign markets in the 2011 Great Wall drilling is 37 sets. In the past two years, the demand for this equipment has gradually expanded. The drilling measurement equipment and technology have long been in the hands of three well-known foreign engineering and technology companies. Competing with these companies on the same stage, the Great Wall drilling has no way to rely on the shortcut to buy equipment. Moreover, the core competitiveness can not be bought.

This means that equipment that does not have independent intellectual property rights will not be able to enter the high-end market bidding.

Great Wall Drilling participates in international engineering and technical services. Where is the way out? Only take the road of independent research and development.

If you take this road, the Great Wall Drilling in the international market can completely get rid of the situation of being controlled by people, and at the same time, through technological upgrading and adjustment structure, to achieve business transformation and leapfrogging to high-end development.

This is tantamount to a technological revolution for the Great Wall drilling. Previously, experts in the domestic logging industry agreed that the LWD technology is “the key technology of China's oil and gas in the early 21st century”, both in terms of the impact of technology on production and core competitiveness, and on market share and technology development prospects. The development of logging while drilling technology and equipment has become the consensus of the domestic logging industry.

Breakthrough requires vision and courage. "Enterprises can only achieve sustainable development if they dare to face contradictions and problems." The decision-making layer of the Great Wall Drilling has made up its mind that it is necessary to use the measurement and control system while drilling as a breakthrough to develop equipment and technology with independent intellectual property rights.

At the beginning of 2010, Great Wall Drilling launched a high-end drilling instrument research and development strategy, concentrated its strengths to build high-end technology tools, and insisted on independent innovation and equipment and technology with complete intellectual property rights.

International cooperation promotes triple jump

For a long time, many domestic enterprises and research institutes have carried out many studies to seek to change the passive status of equipment and technology in the logging while drilling. However, according to traditional scientific research ideas, domestic enterprises and research institutions have not realized the independent research and development of this equipment, and there are still gaps in domestic research on basic theory.

In the field of measurement while drilling high-tech power, large foreign companies monopolize technology and market for decades. The Great Wall Drilling Program has developed high-end drilling equipment in a short period of time, completing key core technology research and narrowing the gap with international first-class companies. For many people, this is an insurmountable gap.

In recent years, the scientific and technological development path of Great Wall Drilling has demonstrated the third-level jump in the field of measurement while drilling: from 2010 to the end of 2011, completed the research and development and field application of high-end equipment while drilling electromagnetic wave resistivity logging tool; completed international in 2014 The development and field application of the top-mounted electromagnetic wave resistivity logging tool for drilling while drilling; the near-bit geosteering system, the neutron density porosity logging tool while drilling and the directional rotating guiding system are planned to be launched in the “Twelfth Five-Year Plan” At the end of the day, the gap between this and the major international companies will be shortened to three to five years.

The international cooperative research and development model has enabled the Great Wall Drilling Scientific Research Innovation to break through the limitations of traditional thinking, and has also taken the lead in breaking the bottleneck in the development of measurement equipment while drilling. The high-end equipment dream that has been chasing for many years has finally become a reality.

Technological breakthroughs have also brought about a shift in the way of thinking, which has enabled Great Wall Drilling to go further on the road to technological innovation.

In the process of achieving independent innovation, Great Wall Drilling relies on international cooperation and has world-class R&D strength and platform. At the same time, as the main body of the project, the domestic team took on the overall design task of the project research and development, and effectively invigorated the on-site application results accumulated by the Great Wall Drilling for many years. According to international practice, the development cycle of high-end equipment and technology in the field of measurement while drilling is usually 5 years. Through the formation of an international R&D team, the Great Wall Drilling While Electromagnetic Resistivity Logging Tool took only 18 months from the project to the field application; the development of the azimuth resistivity while drilling took only two years.

The international platform is highly sophisticated

The experience of many years of hard work in overseas markets has made the decision-making layer of the Great Wall Drilling realize that participating in the international market competition depends not only on equipment, but also on the quality of people.

In 2009, Zhang Lei graduated and entered the domestic R&D team. In the process of conquering the six key technologies of measurement while drilling equipment, he put forward his own unique insights and ideas, and also published several papers related to drilling instruments, and has a number of patents. Now, he is the person in charge of developing the unique side of the azimuth resistivity while drilling.

Since entering the domestic R&D team, young people like Zhang Lei have gained different “special” research experiences from their peers. At the youngest level, he participated in the most advanced scientific research projects in the world, and carried out scientific research with leading experts at home and abroad. He also became a young expert in the field of measurement while drilling.

At present, the domestic R&D team has grown from the initial 8 to 92. In addition to the three on-site technical application experts, the members involved in research and manufacturing are young people who have graduated in the past five years. Among them, 8 engineers and technicians have already possessed the second-level professional research skills. Ten young people who graduated from college only two years embarked on the R&D and manufacturing position of measurement and control technology while drilling. Their growth benefited from the technological innovation platform provided by Great Wall Drilling.

At the same time, the young people who have grown up on this platform have used their expertise in their fields to develop and improve five enterprise standards, two system documents and five SOPs for the azimuth resistivity while drilling, making this unique equipment in the country with industry standards. , with operability. What is even more rare is that the team introduces product quality and process control into the project management, and organizes the test data of 48 strings of instruments put into use into a database. The inspection records of each set of instruments are well documented on the computer and the parameters are adjusted. Data is traceable at every stage. This move has pushed the research management of Great Wall Drilling to a step towards standardization and digital management.

Through international projects or key projects, a group of young scientists and technicians with international vision and strength will be trained to make these young people play an important role in scientific research projects, thereby improving the overall level of scientific research and development.

This is the path of scientific and technological innovation that the Great Wall Drilling insists on.
