热解参数预测储层产能的方法研究

Research on Predicting Reservoir Productivity Using Pyrolysis Parameters

利用热解参数的液态烃 S_1、重烃 S_2及总烃 S_1+S_2的含量变化-与单位含油厚度产能 Q/H之间建立单对数坐标关系.而得到其线性回归方程.再经数学变换求取储层产能方程。该课题解决了达西产能预测公式的不足,简化了现场人员的计算步骤和繁琐的参数优选,特别有利于滚动勘探开发的现场快速决策,具有简便、快捷特点,从其10口井13个层段的应用效果分析,效果良好,是一项较优秀的研究成果。

Adopting the content variation of liquid hydrocarbon s_1,heavy hydrocarbon s_2,total hydrocarbon s_1+s_2 of pyrolysis parameters,plus unit oil bearing thickness,setting up single logarithmic grid relationship,to obtain its linear regression equation,then through mathematical changing to get the reservoir productivity equation.This subject solves the deficiency of Darcy Formula,simplifies counting procedure and severe parameter optimum.Especially has the advantage of well site fast decision—making in rolling exploration and development.From its 10 testing wells,13 inter- vals analysis,the technique has good effects.
