Abstract

Abstract:

In order to optimize the effect of Bohai oilfield regulation and flooding in B water injection development, the numerical simulation software of CMG reservoir was used to carry out optimization research on the effect of "weak gel+water?based microspheres" combined displacement to improve recovery,and according to the known geological reservoir properties of the oilfield,the actual three?dimensional geological model was established,and the historical fitting was carried out in combination with the previous production history.The factors affecting the modulation effect of single section of plugged weak gel modulation,single section of water?based microsphere modulation and driving and the factors affecting the modulation effect of "weak gel+water?based microspheres" were analyzed and optimized,and the related production indexes were predicted.The results show that the combined modulation effect of "weak gel+water?based microspheres" is significantly better than that of a single segment of plug modulation and driving.The optimal injection process parameters of the modulated blocking agent (weak gel) were selected through numerical simulation:the injection mass fraction is 0.50% crosslinker,the injection amount is 0.000 11 PV,the injection speed of A2H well is 240 m³/d,and the injection speed of A3H well is 200 m³/d.The optimal injection process parameters of the modulator (water?based microspheres) were selected through numerical simulation: the injection mass fraction is 0.30%,the injection amount is optimally 0.003 00 PV,and the injection speed of A2H and A3H wells is about 500~600 m³/d. This design scheme can effectively achieve the purpose of increasing precipitation and oil recovery.

摘要：

为优化渤海B油田注水开发油田调驱效果，利用CMG数值模拟软件，围绕“弱凝胶+水基微球”组合调驱提高采收率效果展开了优化研究。根据该油田已知的地质油藏属性，对生产井的历史数据进行历史拟合，建立了实际三维地质模型，对影响单一段塞弱凝胶调驱、单一段塞水基微球调驱以及“弱凝胶+水基微球”组合调驱效果的因素进行分析优化设计，并针对相关生产指标进行了预测。结果表明，“弱凝胶+水基微球”组合调驱效果明显优于单一段塞调驱效果；通过数值模拟优选出调剖剂（弱凝胶）最佳注入工艺参数：质量分数为0.50%，注入量为0.000 11 PV，A2H井、A3H井注入速度分别为240、200 $m 3 / d$ ；通过数值模拟优选出调驱剂（水基微球）最佳注入工艺参数：质量分数为0.30%，注入量为0.003 00 PV，A2H井、A3H井注入速度均为500~600 $m 3 / d$ 。组合调驱方案能有效达到降水增油和提高原油采收率的目的。
