摘要
缝洞型碳酸盐岩油藏的储集空间由溶洞、裂缝及溶孔组成,介质类型复杂,大规模油藏数值模拟中采用单重介质或双重介质都不能表征洞、缝、孔的综合流动特征。提出了一种新的多重介质数值模拟方法,建立了数学模型,有效解决了溶洞、裂缝与溶孔介质间的流动方法,推导了数值解法,通过实例测试,计算结果可靠,从而形成了缝洞型油藏大规模数值模拟的技术手段。
The accumulation space (AS) of fractured cave oil reservoirs is composed of solved caves, fractures and solved holes. Because of the complicated media types, the adopted single and dual media in the large-size numerical simulation cannot characterize the comprehensive flow features of these three components. Therefore a new multi-media numerical simulating model is developed and furthermore the mathmetical model is established, thus the flow method among the above media has been effectively presented and moreover the solution method of the simulation is derived. Through the actual tests, the calculated results are reliable, so the technical approaches for large-size numerical simulation of the fractured cave oil reservoirs.
