摘　　要：针对枣园油田存在的油藏流度低、构造复杂、工艺适应性差等问题,在该油田开展强水淹层孔隙结构参数的理论研究,对注水前后的孔喉结构的变化情况进行了分析,同时根据储层非均质性强的特点现场实施了相控注水、点弱面强、投球调剖、工艺优化和注水吞吐等技术,实现该油田减缓自然递减和增加可采储量的双重目的,使该油田综合开发水平由三类上升到一类。Theoretical study on pore structure parameters in heavily watered-out zone has been conducted in Zaoyuan oilfield in accordance with the problems such as low mobility,complex structure and poor process adaptability.The change of pore throat structure before and after water injection is analyzed.Meanwhile,phase-controlled water injection,weak at point and strong on plane,ball injection profile control,process optimization and cyclic water stimulation are performed in the oilfield in accordance with the characteristics of highly heterogeneous reservoir to attain the dual goal of slowing down natural decline and increasing recoverable reserves,thus making the integral development level of this oilfield upgrade from Class three to Class one.
