摘要
锦州油田稠油区块进入高轮次吞吐阶段后,油层层内、层间矛盾愈加突出,层内存水增多,导致边水内侵,层间水窜,油井含水90%以上,严重影响区块油井的正常开采。通过对该区块油藏研究及油井生产历史研究,及对施工工艺参数的优化设计,选择合适的药剂,并进行配方及工艺改进,实施高温调剖措施,达到了良好的堵水、防窜效果,对区块的后期开发奠定了基础。
As the heavy oil block of Jinzhou oilfield has entered the period of multiple cycled steam huff and puff,water cut is a-bove 90%,in layer interference and interlayer interference became obvious,coupled with increased interlayer water,invaded edge water and interlayer water channeling have been caused,and all of these have a serious effect on normal pro- duction.Through the analysis of reservoir,production history, optimized design of parameters,the proper agent has been chosen to perfect the formula.The technical application proves the water plugging and channeling preventing at high temperature has achieved good results and will provide a solid foundation for field development.
