摘要:
致密油藏压裂开发过程中具有油藏多相渗流和储层裂缝网络非均质等特征，导致多裂缝水平井的油水流动模拟难度较大，致密油藏多裂缝水平井生产过程的模拟方法难以同时耦合上述特征．针对致密油藏基质-裂缝双重介质系统内油水两相瞬态流动提出一种新的数学解析模拟方法，该方法考虑了基质-裂缝网络-水力压裂裂缝多重介质系统内油水两相渗流特征，同时引入动态泄流面积模型解决储层裂缝非均质问题，基于Newton-Raphson方法求解基质-裂缝网络-水力压裂裂缝系统3个区域内物质平衡方程，准确、系统地模拟和预测压裂水平井在生产过程中不同区域内的平均压力、累产油/水量和日产油/水量等随时间的变化规律.该方法以实验室数据为约束，减少解析计算的计算量，可提升对致密油藏基质-裂缝双重介质系统内油水两相瞬态流动的认识，指导致密油藏的高效压裂开发.
Abstract:
The fracturing development process of tight oil reservoir has the characteristics of multiphase seepage and heterogeneity of reservoir fracture network, which makes it difficult to simulate the oil-water flow of multi-fractured horizontal well. In this paper, a novel mathematical analytical simulation method for oil-water two phase transient flow in matrix-fracture dual-porosity system of tight oil reservoirs is proposed, which considers the characteristics of oil-water two-phase seepage in matrix-hydraulic fracture-fracture network dual-porosity system. At the same time, a dynamic drainage-area is introduced to solve the fracture heterogeneity problem. The material balance equations in the three regions of matrix-hydraulic fracture-fracture network system are solved based on Newton-Raphson method. The changes of average pressure, cumulative oil-water production and daily oil-water production with time in different regions of fractured horizontal wells during production are accurately and systematically simulated and predicted. With laboratory data as constraints, this method can reduce the amount of analytical calculation，improve the understanding of oil-water two-phase transient flow in matrix-fracture dual-media system of tight oil reservoirs and guide the efficient fracturing development of tight reservoirs.
