针对双河油田上倾尖灭区开发生产中存在的主要问题,开展了油砂体细分对比、油藏剩余油分布特征研究和现注采井网的适应性分析,提出了针对上倾尖灭区油藏特点的增储上产综合挖潜对策。矿场应用取得了可喜的效果:井网完善程度增加9.4个百分点,注采结构趋于合理,油水井数比由2.3:1降为1.85:1,新井投产和老井措施累计增油12.5×104t,新增地质储量156×104t,水驱采收率提高4.3个百分点。
According to the main problems existing in the development and production of the updip tip-out area in Shuanghe Oilfield, the subtle contrast of the oil sands body, the research on the distribution characteristics of the remaining oil in the reservoir and the adaptability of the existing well pattern are carried out. Explosion zone reservoir characteristics of the reserve increase comprehensive production potential tapping measures. The application of the mine has achieved gratifying results: the improvement of the well pattern has increased by 9.4%, the structure of injection-production has tended to be rationalized, the ratio of wells to wells has dropped from 2.3: 1 to 1.85: 1, 104t, new geological reserves of 156 × 104t, waterflood recovery increased by 4.3 percentage points.
