摘要：聚合物驱后期由于注人液沿高渗透大孔道突进，导致注人压力较低，采油井含水率上升速度加快。为改善萨中开发区125m井距一类油层区块聚驱开发效果，根据X区块油层的发育特点及不同调剖剂的性能特点，开展了整体调剖试验。结果表明，应用整体调剖技术后，区块注人压力上升1.9MPa，含水率月上升速度减缓
0.4百分点。整体调剖技术在聚驱后期区块开发中起到了一定作用。关键词：聚合物驱；采收率；一类油层；调剖

Abstract : In the late period of the polymer flooding, the sudden penetration of the injected solution through the big and high-permeability channels results in the lower injection pressure and faster watercut rising speed in the oil pro-ducers. In order to improve the polymer flooding effects of Type I oil reservoirs in Sazhong Development Block with 125 m well spacing, according to the reservoir developed characteristics in Block X and performance properties of different profile controlling agents, the test of the integral profile control was conducted. The results show that after the stimulation, the injection pressure of the block rises 1. 9 MPa and the rising speed per month of the water cut slows down 0. 4%, a certain effects are achieved for the technique applied in the later polymer flooding production of the block.
Key words: polymer flooding; recovery factor; Type I oil reservoir; profile control
大庆油田开发以来，历经一次采油及二次采油。为了进一步提高采收率，大庆油田自20世纪70年代开始进行聚合物驱探索性试验，至21世纪进入了小井距高质量浓度聚合物驱阶段，试验中心井最高提高采收率20百分点以上。萨中开发区借鉴试验

效果，采取与其相近的注人参数设计，进行125m井距高质量浓度聚合物驱，最大含水率下降31.4百分点。但是125m井距一类油层聚合物驱进人含水回升阶段的时间较250m井距要早，并且含水率上升速度较快。在这一阶段含水率上升速度快成了聚驱
