摘要
本文以五点注采井网为例，利用黑油模型研究了二次采油中注采量及油藏面积波及系数随裂缝方位、压裂井别、裂缝穿透率及无因次裂缝导流能力等的变化规律，得出了规律性认识。它可应用于需经压裂开发的新区中注采井网的部署及给定注采井网下的总体压裂优化设计。
Taking five - spot injection production pattern as an example, this paper makes a study of variable law of injectidn rate, production rate and areal sweep efficiency with fracture orientation, fracturing well distinction, fracture penetration ratio and dimensionless fracture conductivity with the help of black oil model. Some regu1ar knowledges are obtained in research, which can be used to injection -production pattern configuration in a new oilfield developed by fracturing and overall optimum design of fracturing for a given injection - production pattern.
