Energy-saving and environmental protection screw pump increase production efficiency
Abstract: At the present stage of oilfield development, the screw pump is an advanced new process for mechanical oil extraction. It has the characteristics of large pumping force, high pressure, strong convulsions, good stability, and low shear force in the oil and liquid lifting process of oil wells. It applies not only to onshore well production but also to off-shore offshore oil production. In the production of oil, gas, and liquids, it plays an important role in security, security, environmental protection, production increase, and efficiency gains, and is highly favored by mine operators.
1. The screw pump highlights the increase in production, and the efficiency of the victory is that the Xianhe Oil Production Plant boldly uses the screw pump extraction method for mining and has achieved significant yield increase and efficiency gains. Block 1 in Caogu is one of the main production blocks in Anle Oilfield. With the rapid development for many years, the bottom-water in the formation caused the “vibrant†flooding of oil wells to become increasingly prominent. The effect of conventional mining methods and composite plugging and control of bottom water is increasing year by year. Worse. Through the large-displacement screw pump extraction oil extraction test, the “water-control and oil-recovery mode†has been transformed into a “large-displacement extraction methodâ€; by optimizing the technical parameters, the production time rate of oil wells has been improved, and the bottom water reservoir has been fully exploited. potential.
Large-displacement screw pump is a multi-headed screw pump for liquid extraction. It has features of large displacement, high pressure, low shear force, etc. It is suitable for the needs of large-displacement pumping and extraction, and can effectively solve the sucker rod. Easy to break off and control the depth of the pump, but also to maintain the stability of the pressure difference, a constant amount of liquid extraction and the dynamic balance of the volume of oil supply, can fully allow the production of oil wells.
2. Screw pump boosts security against theft and protects the environment Shengli Oilfield's oil production plant in the first oil production plant uses the screw pump as a “bleed pump†to produce the oil. In only one year, it recovered more than 1,500 tons of oil and saved 2.8 million yuan in economic losses.
In recent years, with the deterioration of the security environment in the oil area, criminal activities have become increasingly rampant, and the phenomenon of single-hole and mixed pump pipelines being punctured and stolen has frequently occurred. After analysis by engineers and geologists, the main reason is that there are defects in the emptying method. In the past, when the lawbreakers broke the pipeline, the small class personnel simply evacuated the crude oil into the emptying tank. The formation of the ground oil could not be recovered at all, and was severely plundered by lawless elements, resulting in a larger area of ​​pollution and unfavorable to the management of metering stations. The "trick-taker" criminals, driven by economic interests, will steal pipelines more frequently. Therefore, if you want to get rid of this “poisonous tumorâ€, you must start by changing the way to vent.
After the application of this technology, the loss of crude oil caused by efflux and pollution to the environment were reduced, the progress of pipeline maintenance was accelerated, and the oil well rate was increased. Moreover, due to the change in the method of emptying, the "resources" of illegal oil theft were blocked, effectively reducing the occurrence of sabotage. The screw pump is the backbone of the crude oil production in the Shengli Yudao Oilfield for the wells that are long-lived. During the "Ninth Five-Year Plan" and "Tenth Five-Year Plan" period, the "Longevity" screw pump wells at Jurassic Sea increased year by year.
Because of the large pumping force and stability of the screw pump, it is very suitable for offshore oil production that is far from land. Since the "Ninth Five-Year Plan" period, the technicians of Shengli Offshore Oil Development Company have combined with the underground dynamics and production characteristics of Hudao Oilfield to rationally introduce advanced screw pump oil extraction technology and promote it in a large area. With the continuous deepening of the understanding of the screw pump oil production technology and the improvement of the operating technology, the screw pump oil production process has gradually been improved in the Yudao Oilfield. Through 6 years of on-site practice and operation, the company's technical staff has improved the implementation of screw pump hollow rod technology, double-headed screw pump technology, screw pump frequency conversion soft start technology and other technological measures, formed a more complete offshore screw pump oil production process The system presents an excellent situation in which the number of long-life screw pump production wells at sea has increased year by year. The "longevity" (long maintenance period) of the screw pump well in Shengli Chengdao Oilfield has become a common phenomenon, laying a solid foundation for increasing the production rate of oil wells and increasing the output. According to the statistics, the maintenance period of the screw pump wells in Yudao Oilfield has exceeded 2 years. There were 36 wells (up to 802 days), 16 wells during the extinction period of more than 3 years (1098 days), 9 wells during the exemption period exceeding 4 years (1466 days), and exemption periods exceeding 5 years (1826 days). There is one well, which has made outstanding achievements in the jump growth of crude oil production in Shengli Oilfield offshore oil field, and also provided a reliable guarantee for the sustained and stable development of the oil field during the “10th Five-Year Plan†period.
3, buy a good screw pump is to improve the efficiency of the use of protection, governance, maintenance trouble, so the choice of a practical production needs, a reasonable screw pump can ensure the smooth production, but also reduce the cost of repairs. Now we introduce some experience in the application of the screw pump as follows: First, the screw pump speed selection screw pump flow and speed linear relationship, compared to low speed screw pump, high speed screw pump can increase the flow and The lift, but the power is significantly increased, the high speed accelerates the abrasion between the rotor and the stator, must be the screw. . . Screw pumps are widely used in the transportation of water, wet sludge and flocculant liquids in sewage treatment plants due to their characteristics of variable delivery, strong self-priming ability, reversibility, and the ability to transport liquids containing solid particles. . Screw pump selection should follow the principles of economy and fairness. If the design choices are poorly considered, the use, management, and maintenance will be endangered. Therefore, according to the actual production requirements, a reasonable screw pump can ensure the smooth production and reduce the cost of repairs.
