摘要

摘要: 与常规井数值模拟相比，非常规井数值模拟侧重于刻画垂直、水平井筒内的多相流动，解释由于摩擦、静水力、加速度以及滑移造成的各相之间的速度差及压力损失，模拟井下流量控制设备及复杂现象.从复杂结构井的流量方程、多相井筒管流与油藏渗流耦合模拟、多段井模型、井下流量控制设备模拟、近井区域粗化、井下复杂现象模拟和嵌入式裂缝模型7个方面出发总结了非常规井数值模拟技术研究进展和主要缺陷.基于多段井模型的井筒油藏耦合数值模拟、扩展井模型与油藏模型耦合模拟、流固耦合数值模拟、对井下监测调控设备的数值模拟以及多段压裂复杂结构井的数值模拟是未来的发展趋势.

Abstract: Compared with the numerical simulation of conventional wells, the numerical simulation of unconventional wells focuses on the characterization of multiphase flow in vertical and horizontal wellbores, the explanation of the velocity difference between different phases and the pressure loss due to friction, hydrostatic force, acceleration and slip of each phase, and the simulation of the downhole flow control equipment and other complex phenomena. The research progress and existing defects of the numerical simulation techniques for unconventional wells were summarized from 7 aspects including the flow equations for complex-structure wells, the multiphase pipe flow and well-reservoir coupling simulation, the multi-segment well model, the downhole flow control device simulation, the near-wellbore area coarsening, the downhole complex phenomena simulation and the embedded discrete fracture model. The wellbore-reservoir numerical coupling simulation based on the multi-segment well model, the extended well model and the reservoir model coupling simulation, the fluid-structure coupling numerical simulation, the downhole monitoring control equipment simulation, and the multi-segment fracture complex-structure well simulation, make the development trend in the future.
