摘要
在油藏开发过程中 ,油藏的渗透率、孔隙度和供油面积等参数不断变化 ,很难确定其精确数值 ,给油藏压力的计算带来了困难。本文提出了只用压力恢复曲线计算油藏平均地层压力的新方法 ,该方法只与压力恢复曲线的形状有关。当压力恢复曲线的直线段斜率和外推压力确定 ,该油藏的平均地层压力即可求得。
During the development of oil reservoir, it's difficulty to estimate the reservoir pressure as the rock permeability, porosity and well drainage area change all the time. This paper introduced a new reservoir average pressure calculation method using pressure buildup curve only. There is a correlation between average reservoir pressure and the shape of pressure buildup curve, and the verage reservoir pressurecan be estimated when the slope of semi-log plot and extrapolated buildup pressure were determined.
