摘要: 利用弱凝胶在高渗透大孔道中的运移及低渗透小孔隙地层中的不可入性能,对存在高渗透通道的水驱油藏进行深部调驱试验,可以改善高含水开采期油层深部的非均质程度,实现油藏的稳油控水(或增油降水).应用弱凝胶在辽河茨榆坨采油厂青龙台油田龙-11区块进行的整体调驱矿场试验结果表明,弱凝胶深部调驱可以有效地改善了严重非均质油藏高含水开采期的水驱开发效果,减缓了油田的自然递减速度,并获得较好的增油降水效果.在实施1.5a内,不考虑自然递减及其他作业措施的情况下,区块累积增油7126.1t,产水量减少14054m3,投入产出比大于1:7.

Abstract: The weak gel has the migratory aptitude in the high-permeability path and the impenetrability in the low-transmissibility fine pore layers.The water drive reservoir with high-permeable path was deeply modified and flooded using weak gel to improve the heterogeneity degree of deep oil layers.The application effect of weak gel in Long-11 Block of Qinglongtai Oil Field in Ciyutuo Production Plant of Liaohe Field indicated that the deep modifying-flooding effect of weak gel efficiently ameliorated water-flooding development of the reservoir with high water-cut and high heterogeneity,slowed the decline rate of oil production and accomplished good result of increasing oil and reducing water.During one and a half year,the cumulative increasing oil production was 7126.1 tons,the water production was reduced by 14054 cubic meters.The input-output ratio was more than 1:7 without considering natural decline and other operation measures.

Key words: high-water-cut reservoir, tract profile control, weak gel, modifying and flooding agent, profile modification agent, field test
