随着油藏的不断开发,采油作业二区主力油藏早已进入高含水开采期,目前油井平均含水已达到92.7%,高含水一直是该区块的首要问题。要保持油藏的稳产,必须做好“稳油控水”工作。为了解决油井含水高的难题,我们研究了油井的下泵深度与含水的关系,引入油水界面这一概念,从降低产出液含水方面入手,优化下泵深度,达到增加产量、提高效率的目的,并取得较好效果。
With the continuous development of the reservoir, the main reservoir of the second zone of the oil recovery operation has already entered the period of high water cut. At present, the average water content of oil wells has reached 92.7%. High water cut has always been the primary issue in the block. In order to maintain the stable production of the reservoir, we must do a good job of “controlling oil stability”. In order to solve the problem of high water cut in oil wells, we studied the relationship between the depth of sub-pumping well and water content in oil well, introduced the concept of oil-water interface, and started from the aspect of reducing the water content of produced liquid to optimize the pump depth to achieve the purpose of increasing output and improving efficiency , And achieved good results.
