In 2006, the electricity consumption was 210 million kwh; in 2007, the electricity consumption was 207 million kwh; in 2008, the electricity was 204 million kwh when the two experiments of Jin 45 steam flooding and Jin 16 chemical flooding were put into operation in succession; Less than 170 million kwh of electricity is used up to now. These figures were created at an additional 6600 kilowatts. Low energy consumption is an important symbol of low-carbon economy. For the petroleum enterprises of the grass-roots oil production plant, low energy consumption not only related to production costs, but also reflect the corporate social responsibility. This set of power consumption figures, so that people see the grass-roots oil refinery to reduce energy consumption have more potential space. Jinzhou oil production plant is how to do it? Electricity optimization: Reliable operation is a prerequisite for low-cost operation Like many old oilfields, the power system in Jinzhou Oil Production Plant that has been under exploration for more than 30 years has long been "old-fashioned." The occurrence of grid accidents is the culprit of electricity loss. Due to the geographical environment, most of the high-voltage lines in this factory are located in the vicinity of Reitang and Hetao. The poles and metal fittings of the line have been exposed to saline-alkali and humid environment over a long period of time. Coupled with natural disasters, the reliability of power supply is seriously threatened. In response, Jinzhou Oil Plant on the grid quality of operation overall optimization and standardization transformation. During the process of power grid transformation, the factory totally renovated and rehabilitated 45.6 kilometers of lines, replaced some of the insulated forest lines with insulated conductors, and installed 465 lightning arresters to reduce the risk of lightning strikes. Seriously do a good job of routine inspection work, adhere to the daily patrol line, patrol the night once a week, special patrol line, accident patrol line. In the past 4 years, over 300 trips of various accidents have been discovered and dealt with through patrol lines. In particular, night patrols focus on line equipment that is not easy to find defects during the daytime. Temperature measurement effectively guarantees the safe and reliable operation of the power grid. The accident rate in a hundred kilometers of grids dropped from 3.5 times a year to 2.5 times. Fine management: Primary power plant power consumption is reduced to a minimum value Only through the fine management, in order to control the power point in each link, reducing the power consumption of the entire oil production process. Jinzhou Oil Production Plant managers on the entire oil production process monthly and annual electricity consumption in-depth analysis found that 99% of electricity consumption occurred in the gathering and transportation, water injection, steam injection, mining and other key areas. Detailed management procedures for each key area, compressed invalid cycle, to develop a reasonable working system, to maximize electricity savings. In the oil recovery system, by dynamically adjusting the production system of oil wells and equipment, the optimal combination point of the electricity consumption is sought by the optimal matching of the equipment. In the gathering and transportation system, the external power output and water injection amount are rationally deployed to achieve Optimal status. Since the beginning of this year, the plant has put the key point of saving electricity on reducing inefficient and ineffective cycles and implemented the energy-saving management mode of "increasing single-well production and lowering the number of open wells on a daily basis." All oil-producing areas scientifically and reasonably determined to produce Parameters, to develop the best management of open wells between the system. To date, measures have been taken to open 193 low-yield wells, reducing 114,000 days of ineffective production and saving 2.3 million kwh. In recent years, in the practice of building low-energy oil recovery plants, the factory has been continuously improving its work system for electric power consumption and has successively formulated rules and regulations such as the Measures for the Administration of Hydropower Systems and the Detailed Rules for Quantitative Assessment of Hydropower Systems. The management of electric power has become standardized and standardized the way. Scientific assistance: the best way to achieve low-power oil recovery This year, Jinzhou Oil Production Plant implemented a total of 324 wells hoist system efficiency technology, the average machine efficiency increased from 14.5% to 23%, saving 1.2 million kWh; installation Energy-saving distribution box, distribution cabinet 120. The manager of this plant will be scientific and technological progress as a booster to achieve low-power oil production, and actively carry out advanced energy-saving technology and equipment research and development, introduction and application. This year alone, the plant implemented seven major technical measures such as installing energy-saving power distribution boxes and oil well inverters, replacing high-energy-consuming complete sets of equipment and high-pressure water injection. Each of these science and technology projects is a "fulcrum" for achieving low-power oil production. The application of screw-pump production technology is an example of this plant's successful privatization of "low-power oil production." In 2008, the average daily open well number of Jinzhou Oil Production Plant was 1,769, an increase of 24 open wells compared with that of 2007 and a slight increase from the average daily open well number of 2008 and an increase of electricity consumption. However, the application of screw pump production technology has become a key measure to effectively solve this problem, and ultimately achieve the goal of increasing the number of open wells but not increasing the power consumption. Due to the high power consumption of the pumping mechanism mechanical lifting process, the plant began to explore efficient and energy-saving process technology for the well. Four years ago, it began to work on 91 blocks of heavy oil with suitable conditions such as screw pump cold storage technology. It has completed 14 supporting technologies and received significant oil-saving and electricity-saving effects. So far, the plant has used this technology in 187 wells, saving a total of 16.98 million kWh.
