在水力渗流单元理论研究基础上,综合应用地质、测井、岩心分析化验、生产测试等基础资料,对河南油田双河Ⅳ1-3油组测井资料进行数字处理。通过水力渗流单元划分,利用井间相控技术开展储层定量描述,建立水力渗流单元模型。利用数值模拟得到的油藏精细地质描述研究结果,结合油藏动态情况,对双河Ⅳ1-3油组实施注聚措施,预计比原水驱增产原油36.53×104t、提高采收率4.61个百分点。
Based on the theoretical study of hydraulic seepage unit, the logging data of IV1-3 oilfield in Shuanghe, Henan Oilfield are digitally processed by comprehensively applying the basic data of geology, logging, core analysis and test, and production test. Through the division of hydraulic seepage units, the reservoir quantitative description is carried out by using the crosswell control technology to establish the hydraulic seepage unit model. Based on the results of numerical simulation of the fine geologic description of the reservoir and the combination of the reservoir dynamics, the injection and enrichment measures are applied to the Shuanghe IV1-3 oil formation. It is predicted that the crude oil will be 36.53 × 104t more than the original water flooding and the recovery rate will increase by 4.61 percentage points.
