摘要:
针对海上聚驱油田高含水后期剩余油分布复杂及油井压裂选井、选层难度大等问题,综合运用改进后的无因次产液指数计算方法评价油井产液能力,分析了聚驱后油井合理产液变化规律,进而选择无因次产液指数下降幅度大于30 %的亟须治理的油井;结合储层精细分析、剩余油精细刻画,进行了高含水后期油藏驱替倍数量化表征和分级评价,有效量化了各层的剩余潜力,建立了渤海J油田高含水后期压裂措施的合理选井、选层的方法和量化依据,保障了海上压裂技术的增油效果。矿场实践表明,该技术方法合理有效,压裂措施实施后单井日增油可达14~42 t,增油效果显著,可为类似处于高含水后期的油田的压裂措施选择及产能改造潜力评价提供借鉴。
