摘　　要：尕斯库勒油田N1-N21油藏已进入中高含水阶段,油藏受储层分布和隔层薄的影响,注水井单层突进,油藏水驱动用程度较低,仅仅依靠换封、分注、混层酸化作业,无法动用全部需要的吸水层位。通过精细地层对比,确定注水井与周围采油井的连通状况;采用分层酸化,启动注水井未吸水的连通层,到达提高水驱动用程度,完善砂体注采井网的目的。N1--N21 Reservoir in Gasikule Oilfield has gone into medium--high water cut stage. Influenced by thin reservoir distribution and interlayer, water--injected wells break through monolayer and producing degree of water-flood is low, making it incapable to employ all the needed water intake layer only by exchanging the packer, separated injection and mixed--layer acidizing. It is suggested that fine stratigraphic correlation be applied to confirm connected conditions of water--injected wells with producing wells nearby and that separate layer acidizing be adopted and connected layer without water be launched to enhance waterflcod producing and improve sandbody injection-- production pattern.
