原油高压物性经验公式优选方法及应用研究

Study on Oil PVT Correlation Optimization and Its Application

在实践中原油高压物性参数可通过经验公式计算获得,原油组成因素的影响往往使计算结果偏差较大。针对此问题,建立一套定量评价原油高压物性经验公式预测值精确程度的评价方法,给出不同高压物性参数预测的最优经验公式。

In the practice, PVT can be got from empirical formula, whose influence make the calculation deviationbig. According to this problem, we establish a set of evaluation method to determine the accuracy degree of PVTempirical formula prediction value. The optimized empirical formula to make different PVT prediction is obtained.
