本文研究了在垂直裂缝油层中动边界问题和压力动态问题,给出两相流体活塞式驱替椭圆界面的运动方程以及等压椭圆传播的近似解。它们可以应用于二次和三次采油技术中。
In this paper, the dynamic boundary conditions and pressure dynamics in vertical fractured reservoirs are studied. The equations of motion for the two-phase fluid piston displacement elliptical interface and the approximate solution of isostatic elliptical propagation are given. They can be used in secondary and tertiary recovery technologies.
