摘　　要：为提高低渗高含水油井产量,降低含水,以满足中高含水期油藏稳产和提高采收率的需要,通过室内实验研制出一种选择性堵水剂,堵水率在85％以上,是堵油率的4～5倍,具有较高的选择性堵水能力,同时,针对高含水油井形成了一种深部堵水压裂技术.现场试验表明,该技术深部堵水实施后日增油2.3t,降水20％,具有较好的降水增油效果.In order to improve the production and reduce water content of high-water well,a kind of deep water plugging and fracturing technology was developed for such wells,to meet the high water cut stage stable reservoir and enhancing oil recovery.A highly capable selective plugging was developed by lab experiment,and its water plugging rate is 85%,with rate 4-5 times that of the oil plugging rate.For fracture-breakthrough well,the technology of plugging highwater well was proposed.Oil field test shows that the deep water plugging and fracturing technology increases oil 2.3 t/ d and reduces water 20%,has good effect of increasing oil.
