摘要
根据270个原油样品高压物性分析资料,建立辽河坳陷砂岩油藏饱和压力计算的经验方程。选取18口井高压物性资料,应用本地区及国外经验公式进行计算,与实测结果对比,得出用本油田实际分析资料确立的经验公式应用效果要好于国外经验公式。
An empirical equation to calculate the saturation pres- sure of sandstone pool in Liaohe sag is obtained through the analysis on high-pressure physical properties of 270 crude oil samples.The data of high-pressure physical properties of 18 wells are selected,and the saturation pressures are cal- culated respectively by the empirical equations in the area and abroad.In comparison with the measured result,the empirical equation from the local samples is more accurate than the one abroad,which suggests that it is feasible.
