【摘要】 缝洞型油藏储集体类型多样,缝洞组合关系复杂,连续性差,非均质性极强,确定井间连通程度非常困难。基于物质守恒理论,建立一种利用油藏动态快速定量评价井间连通程度的方法,实现了对缝洞型油藏井间连通程度的定量预测。实际应用结果表明:该方法与定性评价方法结合,可提高定量评价缝洞型油藏井间连通程度的准确度,评价结果与示踪剂测试结果非常吻合。更多还原

【Abstract】 Fractured-vuggy reservoirs are characterized by multiple types,complex fracture-vug combination,poor continuity and strong heterogeneity,which makes the determination of the interwell conductivity very difficult. Based on the mass conservation law,a quantitative evaluation method of interwell connectivity for fractured-vuggy reservoirs was proposed,and combined with qualitative evaluation method,the accuracy of the quantitative evaluation of interwell connectivity for fractured-cave reservoirs will be greatly improved. The evaluation results of the method are in good agreement with the tracer test results.更多还原
