In the current oilfield development, the screw pump is an advanced mechanical oil recovery process. In the oil and liquid lifting process of the oil well, it has the characteristics of large pumping force, high pressure, strong convulsion effect, good stability and low shearing force. It is suitable for both onshore oil well production and offshore oil recovery requirements away from land. In the operation of oil recovery, gas production and liquid extraction, it plays an important role in safety and security, environmental protection, production increase and efficiency improvement, and is favored by mine operators.
Screw pump highlights production increase and efficiency
The Shengli River Oil Production Plant boldly used the screw pump to extract the liquid, and achieved obvious results in increasing production and increasing efficiency. Caogu 1 block is one of the main upper production blocks of Anle Oilfield. With the rapid development for many years, the bottom water of the formation caused the “violent†flooding of the oil well to become more and more prominent. The effect of conventional mining method and compound plugging to control the bottom water is increasing year by year. Getting worse. Through the large-displacement screw pump liquid extraction and oil recovery test, the “water-controlled oil-soil mining method†was changed into “large-displacement liquid extraction methodâ€; by optimizing the technical parameters, the oil well production rate was improved, and the bottom water reservoir was fully excavated. potential.
The large-displacement screw pump adopts a multi-head screw pump to extract liquid. It has the characteristics of large displacement, high pressure and low shearing force. It is suitable for large displacement oil extraction and liquid extraction, and can effectively solve the sucker rod. The control problem of easy breakage and down pump depth can also maintain the pressure difference stability, constant liquid volume and dynamic balance of the oil supply volume, which can fully enable the oil well productivity.
Screw pump boosts safety and security, protects the environment
The Shengyou Oilfield Linpan Oil Production Plant produces a screw pump as a “venting pump†and puts it into production. In just one year, it recovered more than 1,500 tons of floor oil and recovered economic losses of 2.8 million yuan.
In recent years, with the deterioration of the security environment in the oil zone, the activities of criminals have become increasingly rampant, and the phenomenon of single-well and mixed-pump pipelines being punched and stolen has occurred frequently. After analysis by engineering and geological technicians, it is believed that the main reason is that there are defects in the way of emptying. In the past, when the illegal elements destroyed the pipeline, the small class personnel simply discharged the crude oil into the venting pool. The formation of the floor oil could not be recovered at all, and it was strictly robbed by the lawless elements. The pollution area was larger and it was not conducive to the management of the metering station. The criminals who "taste the sweetness" are driven by economic interests and will steal the pipeline more frequently. Therefore, in order to get rid of this "cancer", you must start by changing the way of emptying.
After the application of this technology, the loss of crude oil and environmental pollution caused by the outer row is reduced, the pipeline maintenance schedule is accelerated, and the oil well rate is increased. Moreover, due to changes in the way of emptying, the "financial resources" of illegally stealing oil molecules have been blocked, effectively reducing the occurrence of vandalism.
The screw pump is the oil well produced by the screw pump process for the oil well “longevity†escort. It is the backbone of the crude oil production in the Shengli Oilfield. During the "Ninth Five-Year Plan" and "Tenth Five-Year Plan" period, the "longevity" screw pump wells on the island of Yeouido increased year by year.
Because the screw pump has the characteristics of large pumping force and good stability, it is very suitable for offshore oil production away from land. Since the "Ninth Five-Year Plan", the technical personnel of Shengli Offshore Oil Development Co., combined with the underground dynamics and production characteristics of the Chengdao Oilfield, have rationally introduced advanced screw pump oil recovery technology and promoted it in large areas. With the deepening of the understanding of the screw pump oil production technology and the improvement of the operation technology, the screw pump oil production process has been gradually improved in the Chengdao Oilfield. Through 6 years of on-site practice and operation, the company's technicians have successively improved the implementation of the screw pump hollow rod technology, double-head screw pump technology, screw pump frequency conversion soft start technology and other technical measures to form a relatively complete offshore screw pump oil production process. The system presents a good situation in which the “longevity†screw pump production wells at sea increase year by year. The “longevity†(long maintenance period) of the screw pump well in Shengli Oilfield has become a common phenomenon, laying a solid foundation for the increase of production rate and production growth of oil wells. According to statistics, the repair period of screw pump wells in Chengdao Oilfield is more than 2 years. There are 36 wells (up to 802 days), 16 wells with a maintenance period of more than 3 years (1098 days), and 9 wells with a maintenance period of more than 4 years (1466 days). The maintenance period is more than 5 years (1826 days). There is a well that has made outstanding achievements in the jump growth of crude oil production in the offshore oil field of Shengli Oilfield, and also provided a reliable guarantee for the sustainable and stable development of the oilfield during the 10th Five-Year Plan period.
