On October 9th, the first 1200-meter-long continuous line pipe developed and produced by Baoji Petroleum Steel Pipe Co., Ltd. was operated smoothly in Qinghai Oilfield for 15 days. After rigorous testing, all performance indicators were in line with the design. Claim. This indicates that the domestically-made continuous line pipe with international advanced level has entered the promotion and application stage.
Coiled tubing, also known as flexible tubing, serpentine tubing, or coiled tubing, is typically several hundred meters to several kilometers in length. Its products include speed tubing, work tubing, and continuous line tubing. Key equipment for completion, oil testing, oil recovery, workover and gathering. However, only two U.S. companies were able to produce this high-tech, high-value-added product. Technical research and production processes have remained highly confidential.
To further speed up the localization of coiled tubing, at the end of 2009, Baoji Steel Pipe Co., Ltd. and Qinghai Oilfield Co., Ltd. jointly undertook the “Continuous Pipeline Pipeline for Ground Gathering and Transferring Pipelines†project, which opened a domestically produced 50.8 mm diameter wall thickness. 4.44 mm continuous line pipe, replacing the existing 60 mm diameter, seamless pipe with a wall thickness of 4 mm.
With the close cooperation and unremitting efforts of both parties, in July 2010, China's first continuous line pipe was successfully rolled off at Baoji Steel Pipe Co., Ltd., and on September 24, two separate lines from R39#-1 were placed in the Sebei gas field. The continuous line pipe from R40#-1 gas well to the gathering station has a laying speed of 24m/min, which is more than double the existing operating efficiency of the oilfield. After the tube is completed, a pressure test is successful and the air is smoothly ventilated.
The successful operation of the first continuous line pipe in China has laid a solid foundation for the popularization and application of domestic continuous line pipe in the future.
