摘　　要：为了提高聚合物驱后油藏整体调剖的实施效果,需要对影响效果的各种因素,特别是调剖时机、调剖深度以及调剖轮次等工艺参数进行分析,优选出合理的参数值。运用油藏数值模拟的技术手段,对调剖深度、调剖时机以及调剖轮次工艺参数设计进行了概念模型分析。初步的研究结果表明,调剖深度为1倍强水淹半径,调剖时机在含水漏斗谷底时,效果最好;而且一轮次的整体调剖结束之后,在适当的时机开展第二轮、第三轮整体调剖,仍然能够取得不错的效果。In order to raise the effect of whole block water shut-off and profile control after polymer flooding, it needs to analyze all kinds of affecting factors,especially such as the deep ,occasion and the round of profile control, and optimise approprite parameter value. The paper does some concept model analysis to the deep,occasion and the round of profile control applying reservoir simulation means. The preliminary result indicates that it does the best while the deep of profile control is equal to the strong water flush radius and the occasion is at the moment of the valley bottom of the water cut hopper. And it can yet make the preferable effect to develop the second round or the third at the appropriate occasion after the first round whole block profile controlling.
