摘要:

本文介绍了用加回压和非稳定测定的方法对某气藏岩心进行的水驱气的实验。用Buckley-Leverett驱替理论推导出了适合于水驱气的相对渗透率饱和度计算公式。这对带边底水气藏的开发及其动态分析是有实际意义的。

Abstract:

An experiment of displacement of gas by water by using an unsteady-state flow method and by forcing back pressure is introduced in this paper. According to Buckley-Leverett displacement theory, the relative permeability formula suitable for the displacement of gas by water is derived, and experiment data are obtained. It is of practical significance to the development and performance analysis of boundary bottom water gas reservoirs.
