针对敖包塔油田欠注井多、油层条件差、剩余油潜力分布零散及措施增油难度大等问题,采取了一系列注采关系完善、注水结构及产液结构调整等对策,认识到改善各类油层的水驱效果,有效控制产量递减、含水上升速度是改善低渗透油田开发效果的关键。 In view of the problems such as many underfilled wells, poor reservoir conditions, scattered residual oil potential distribution and difficulties in increasing oil production, a series of measures have been taken to improve the relationship between injection and production, water injection structure and liquid production structure adjustment, The effect of waterflooding of oil-bearing reservoirs, controlling the decline of output and the rising speed of water cut are the keys to improve the development effect of low-permeability oilfields.
