孔店油田含水上升规律及剩余油挖潜措施

针对孔店油田馆陶组油水同层油藏的开发特征,采用油藏工程动态分析法研究孔店油田的含水上升规律,以期改善开发效果。同时利用油藏数值模拟,研究单砂体剩余油分布控制因素、分布规律及相应挖潜措施。结果表明:通过准确预测剩余油富集区,完善注采井网,高粘度稠油区部署热采井,采油井采取放大生产压差提液、卡层堵水等措施可以有效动用油水同层油藏剩余油。

Water Cut Rising Rules And Remaining Oil Potential Tapping Measures of Kongdian Oil Field

Aiming at development characteristics of Guantao group oil-water same layer oil deposit of Kongdian oil field,it has important effect for improving developing effect to study water cut rising rules of Kongdian oil field with oil deposit engineer dynamics analysis,and we study controlling factors,distribution rules and corresponding potential-tapping measures of single-sand body residual-oil distribution by oil de-posit numerical simulation.The result shows that by measures of exactly predicting residual oil enrichment region,perfecting injection-production pattern,arranging thermal production well in high viscosity thick-ened oil and enlarging production pressure drop and liquid extracting,blocked layer plugging water,the re-sidual oil in the same oil deposit layer containing oil and water can be employed effectively.
