胜利油区新增探明储量标定采收率的新方法

在分析影响采收率主要因素的基础上,应用多元回归分析方法,得出了新增探明储量标定采收率的新方法。该方法应用参数包括空气渗透率、地面原油粘度、有效孔隙度和生产井井网密度,参数易取、计算方便,应用近几年新增探明储量区块检验,适应性好,优于胜利油区应用的其他经验公式法。

New method of recovery calibration on newly-found proved reserves in Shengli petroliferous province

Based on analyzing major factors of recovery efficiency, a new method of recovery calibration on newly- found proved reserves are given using multiple regression a-nalysis. The applied parameters in the new method include air permeability, surface viscosity of crude oil, effective porosity and production well spacing density, which are easily got and calculated. Through the verification at the blocks with newly-found proved reserves in recent years, this new method has wide applicability and is better than other empirical formula methods applied in Shengli petroliferous province.
