西江A油田油藏数值模拟

Fine Reservoir Numerical Simulation of Xijiang-A Oil Field

西江A油田是一个多油藏油田 ,已投入开发四年多。目前油藏需解决的主要问题 :一是评价K34油藏的原油原始地质储量 ;二是主力油藏的水淹状况及油田开发潜力。笔者应用油藏数值模拟手段 ,运用饱和度函数标定技术及油藏含水饱和度拟合技术精确建立了油藏模型 ;在历史拟合基础上 ,通过对油水运动规律的分析 ,对K34油藏的原始地质储量及各油藏动用状况及潜力进行了评价。

Xijiang-A oil field has multi-reservoirs, which has been developed for over four years. There are two major problems to be solved at present: one is to evaluate the primary reserves of K34 reservoir;the other is to analyze the flood-out condition and development potentiality of major reservoir. By means of reservoir numerical simulation technology, this paper builds a fine reservoir model using saturation functions scaling and reservoir water saturation matching technology. Based on the history matching, this paper also evaluates the primary reserves of K34 reservoir, the development condition and development potentiality of each reservoir.
