水力压裂产能预测三维三相三重介质模型的建立与求解

Building of A Three - dimensional Three - phase and Triple Media Model for Production Capacity Prediction of Hydraulic Fracturing and Its Solution

借鉴油藏数模在模型和解法上的成功经验,结合采油工程的实际情况,从区块整体改造的角度出发,考虑基岩、天然裂缝、人工压裂裂缝三重介质,提出了一个新型的较完善的油气水三维三相三重介质压裂产能动态预测模型,编制了相应的数模软件包,可进行井组,区块数模计算,也可对双重介质、均质作三维三相、三维二相对比计算。

A new three - dimensional three - phase and triple media model for dynamic prediction of production capacity of hydraulic fracturing is built by using the successful experiences of model building and solution of reservoir numerical modeling and in combination with the practical oil engineering. Corresponding numerical modeling software packages are programmed. They can perform both numerical modeling calculation of well groups and blocks and three - dimensional three - phase or three - dimensional two - phase comparative calculation of dual media and homogeneous media.
