摘要
研究用分形描述油藏的非均质性,并与渗流力学相结合,建立了非均质油藏的基本产能方程。导出了不同形态的油相相对渗透率曲线下水驱分形非均质油藏产量变化规律的方程式,并结合分形地质统计学进行了应用研究。结果表明:本方法因考虑了油藏非均质效应,使预测结果更为合理可靠。
On the Basic of characterizing the reservoir heterogeneity with fractal and coupling with the fluid flow in porous media,this paper presents the basic productivity equations for the heterogeneous reservoirs.Furthermore,a few cases are considered while water flooding under various relative permeability curves for oil phase.Then,with the R/S analysis of the gelolgy statistic,the equations are applied to forecast the productivity for some oil fiels.It shows that the equations are useful and the forecasting results are reasonable and available because of considering the reservoir heterogeneity with fractal.
