【摘要】:機械采油的系統(tǒng)效率是評價一個油田的開發(fā)狀況和開發(fā)水平的重要標準,相比國內(nèi)其他油田,海1塊的抽油機系統(tǒng)效率偏低,平均系統(tǒng)效率為24.5%,達不到26%的標準,因此研究機械采油能耗損失原因并制定相應的降耗措施,對提高海1塊抽油機系統(tǒng)效率和節(jié)能降耗有很重要的意義。本文在海外河油田海1塊地質(zhì)概況和生產(chǎn)現(xiàn)狀分析的基礎上,運用分節(jié)點敏感因素分析的方法對區(qū)塊內(nèi)造成系統(tǒng)效率降低的因素進行研究,結(jié)果表明,海1塊系統(tǒng)效率偏低的主要原因主要是地面效率和井下效率低;以區(qū)塊內(nèi)機采井實測系統(tǒng)效率作為數(shù)據(jù)支持,秉承“一井一策”的原則,有針對性地進行了提高海1塊系統(tǒng)效率方案設計;在海1塊現(xiàn)場實施了提高系統(tǒng)效率的技術措施及優(yōu)化方案設計,取得了良好的效果,平均系統(tǒng)效率提高到26%以上,平均單井增產(chǎn)7.2m3/d,增產(chǎn)增效顯著。
[Abstract]:The system efficiency of mechanical oil production is an important standard for evaluating the development and development level of an oil field. Compared with other oil fields in China, the efficiency of the 1 offshore pumping units is low, the average system efficiency is 24.5%, and the standard is less than 26%. Therefore, the study of the loss of the loss of oil by mechanical oil recovery and the corresponding measures to reduce the loss are made, and 1 blocks in the sea are raised. On the basis of the geological survey and production status of 1 blocks in the offshore oilfield sea, this paper studies the factors that reduce the efficiency of the system in the block on the basis of the analysis of the geological survey and production status of the overseas River oilfield sea. The results show that the main reasons for the low efficiency of the sea 1 system are mainly the ground. The efficiency of surface and downhole efficiency are low. Taking the system efficiency of the well measured system in the block as the data support and adhering to the principle of "one well and one policy", the design of the efficiency scheme for improving the 1 block system is carried out. The technical measures and optimization schemes for improving the system efficiency are carried out in the 1 block of the sea, and the good results are achieved and the average system has been obtained. The efficiency increased to more than 26%, and the average single well production increased by 7.2m3/d.
