Winprop相态模拟软件的应用

THE APPLICATION OF WINPROP,A PHASE BEHAVIOR SIMULATION SOFTWARE

Winprop 是 CMGPROP 的 Windows 版本。它是 CMG 状态方程多相平衡特性软件包,包括流体特征化,组分归并,实验室数据回归拟合,多次接触过程模拟,相态图计算,沥青沉淀等等。本文对 Winprop 相态模拟软件的相态平衡理论及流体状态方程模型进行了分析,并应用此软件,合理划分拟组分体系,拟合流体样品 PVT 分析试验结果,标定了能够有效表征地层流体相态特征的状态方程参数。

Winprop is the Windows version of CMGPROP.Winprop is CMG's equation of state multiphase equilibrium property package featuring fluid characterization,Iumping of components,matching of laboratory data through re- gression,simulation of multiple contact processes,phase diagram construction,solids precipitation,and more. Through analysis of the phase equilibrium theory and fluid state equation model in this software,classifying pseud- ocomponent units,matching the results of fluid samples'PVT experiments have been conducted,and the parameters of state equation that could effectively indicate the reservoir fluid properties have been identified by use of this soft- ware.
