摘要

通过对电缆地层压力测试资料和采集流体样品的PVT组分分析,提出了电缆地层测试储层产能预测的方法,为部分替代DST测试提供了理论基础。首先,利用曲线拟合方法精确求取地层有效渗透率和表皮系数等产能参数;利用采集流体样品的PVT组分分析,确定原油黏度、体积系数和溶解气油比等流体参数,结合电缆地层测试的产能方程,从而计算出储层的采油指数(PI)或单层日产量。

Abstract

Through wireline formation test pressure data and PVT component analysis of fluid samples, a method of reservoir production prediction using wireline formation test was developed to take the place of DST technique. Firstly, effective permeability and skin parameters was calculated by the use of curve fitting. Secondly, using PVT component analysis of fluid samples to determine fluid parameters such as oil viscosity, volume coefficient and dissolved gas oil ratio. Finally, reservoir production index (PI) or daily output of single layer were calculated combining with wireline formation test production equation.
