油田目的层为低孔特低渗储层,油藏边部砂体厚度薄,物性差,需要注水启动压力大,常压下注水困难.本论文针对这一情况开展高压增注可行性研究,通过适当提高井口注水压力来达到增加注水量,提高水驱波及系数,提高单井产油量.

Oil objective layer for low porosity and low permeability reservoir, the reservoir boundary thickness of sand thin, poor physical property, need high water injection starting pressure, pressure water injection is difficult. In this paper, aiming at the situation of high pressure injection feasibility study, by improving the well head injection pressure to increase water injection, improve the water flood sweep efficiency, increase the single well oil production.
