Northwest oil field: there are good ways to increase efficiency, and the double pump water injection of well TK307 improves the bottom water absorption capacity by increasing the water injection volume, reducing the long time of waste liquid discharge after well completion, which provides practical experience for this kind of well water injection to see production in advance, improve efficiency and increase efficiency
on August 7, a sandstorm in the past in Tahe Oilfield brought a hot sunny day. Bu Yuzhong, the dispatcher of the environmental protection engineering management department of the Northwest Oilfield Engineering Service Center, commanded and organized the pump truck to install pipelines in an orderly manner, while Niu Xinfang, a 58 year old pump truck worker, was clamping the flange buckle with an eight pound hammer, and the roaring pump truck was gaining full power, The carbon fiber plug-in hybrid "ireze 7" jointly built by Ningbo Institute of materials technology and engineering of Chinese Academy of Sciences and Chery Automobile will also be unveiled at the exhibition site. In the face of the uncertain economic situation at home and abroad, the raw material industry will rise from 20MP to 35mp. With the sharp increase of pump truck pressure, the downhole pressure gauge will suddenly drop to 17mp, and the parking water will flow rapidly under strong pressure, Niu Xinfang's one hour operation soaked his sleeves with sweat
recently, the environmental protection engineering management department of the center has actively taken various measures to increase the water injection capacity in view of the current increase in the water injection stock of huitahe oilfield, and the global market will reach $37.1 billion in 2017 to ensure the improvement of water injection energy efficiency; With the improvement of the potential tapping and efficiency creation level of the branch company, the average daily reinjection water received in the well completion cycle has increased from 400 m3 to about 850 m3; At present, the daily treatment and pipeline transportation injection volume is increasing, and only 410 cubic meters of water can be injected. Because the well pressure is too high and the reinjection efficiency is low, the technicians of the environmental protection engineering management department of the center, together with the engineering technicians of the Development Research Institute of the oil production plant, have formulated the "one well one policy" water injection scheme, and achieved positive results in the alternative water injection of TK307 pump truck and unit pump in the first oil production plant
Guan Jun, a technician from the environmental protection engineering management department, said: "In order to achieve the standard discharge of TK307 well and increase the discharge, our technicians can only inject 250 cubic meters of water per day according to the well pressure and the unit pump at present; we design to adopt dual interaction and 700 pump truck water injection, and take advantage of the advantage that the water pressure and flow of the pump truck can be adjusted at the same time, dual pressure regulation and water injection, which well solves the problem that the downhole pressure is too high and the water injection volume cannot crack the bottom seam and hole under the back pressure"
"The sulfonated filtrate water, acid kill backflow fluid and completion backflow fluid during the drilling process cannot be treated in time on site, which is prone to affect the efficiency of the drilling rig and the failure of oil well measures to construct." we are to increase the water injection and improve the follow-up acid fracturing and other engineering progress, "said Ma Wen, manager of environmental protection engineering management department
this time, the double pump water injection operation of TK307 well improves the bottom water absorption capacity by increasing the water injection volume, and reduces the problem of long time for well completion to discharge waste liquid, which provides practical experience for this kind of well water injection to see production in advance, improve efficiency and increase efficiency.
