尕斯库勒N1-N21油藏,地质储量4604万吨,可采储量1474.28万吨。目前有采油井399口、注水井164口,年产油56.38万吨,累计产油1012.77万吨;年注水108.15万方,累计注水775.47万方;综合含水66.01%,采出程度22%。目前,该区域面临产量递减快、油水连通率低、含水上升较快、局部供液不足等问题,如何提高油藏的采油速度和采出程度,保持油藏的稳产,是今后工作的重点方向。
Gasculer N1-N21 reservoir, the geological reserves of 46040000 tons, recoverable reserves of 14742800 tons. At present, there are 399 oil production wells and 164 water injection wells, with an annual output of 563,800 tons and an accumulated oil production of 10,127,700 tons. The annual water injection volume is 1,081,500 square meters, with a total injection volume of 7,754,700 cubic meters. The integrated water content is 66.01% and the recovery rate is 22%. At present, the region is faced with the problem of decreasing production rate, low oil-water ratio, rapid rise of water cut and insufficient local liquid supply. How to improve oil recovery rate and recovery and maintain stable production of oil reservoirs are the key directions for future work .
