Preliminary Study on Effect of Machine - building and Reconstruction of Duerxia Gorge Work Area in Yumen Oilfield

According to the China Petroleum Daily, the Ya'erxia Oilfield Operations Area at Yumen Oilfield plans to intensify efforts to reform the mechanical oil recovery system this year, making efforts to reduce energy consumption and reduce costs and increase efficiency. In recent years, the Yaumen Oilfield Duck Gap Oilfield operating area will be refined management philosophy into all aspects of production, the fully mechanized mining system optimization, and continuously improve the development of old oilfield efficiency. More than 140 oil wells in the operational area of ​​Ya'erxia Oilfield are basically produced by mechanical oil recovery. Most of these equipments have been put into operation for many years, and the problems of high energy consumption and large horse-drawn carts are common, resulting in excessive costs. In order to effectively reduce energy consumption, the operating area will improve the efficiency of the mining system as an important task. In the work area of ​​Yaerxia Gorge, Y524, Y137, Y106, Y938, M3 and other 5 oil wells were screened first, and the patented technology of "the lowest energy consumption machine-adopted system design method" was selected. Combining the actual production status of each well, From the lowest point of departure, we optimize the stroke, stroke and pump depth of each well and optimize the downhole tools such as sucker rods, pipes and pumps to achieve the best combination. The reporter learned from a test report in the operation area that the production volume of these five oil wells not only increased in varying degrees but also decreased in all the three trips. In particular, the well number Y938 was reduced from the previous 4 times per minute 2.2 times / min; Y137 wells from the previous 5.7 times / min to 3.5 times / min, the reduction of impulse means saving some power.
