摘要(Abstract)：

聚合物驱后期由于注入液沿高渗透大孔道突进,导致注入压力较低,采油井含水率上升速度加快。为改善萨中开发区125 m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,区块注入压力上升1.9 MPa,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。
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 producers. In order to improve the polymer flooding effects of Type I oil reservoirs in Sazhong Development Block with125 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.
