摘　　要：桩西油田桩139等区块稠油油藏原油黏度高。在原油开采过程中,因边底水活跃造成油井含水率偏高是其主要生产矛盾,针对这一问题,从调堵增产角度出发,开发了一种新型高强度堵水剂ZXDJ-1,基本配方为6.0%改性锂藻土+0.5%多聚甲醛+0.5%酚醛树脂PN760+1.6%增黏剂+0.4%改性CMC。研究证实,该堵水剂具有较高强度、良好的耐温、热稳定性及封堵性能。采用双管并联模式的驱替实验结果表明,堵水剂的优越性表现在对调堵层位不仅具有强的选择性,还具有高耐冲刷性。堵水剂堵水技术现场应用5井次,应用效果证明,取得了较好的油井调堵效果,可为类似油藏调堵工艺提供参考。High viscosity of crude oil in Zhuang 139 block heavy oil reservoir in Zhuangxi oilfield.In the process of crude oil exploitation,the main production contradiction is the high water content of oil wells due to the active bottom water.Aiming at this problem,we have developed a new high-strength water plugging agent named ZXDJ-1.The basic formula is 6.0%modified lithium alginate+0.5%polyformaldehyde+0.5%phenolic resin PN760+1.6%tackifier+0.4%modified CMC.The research confirmed that the water plugging agent has high strength,good temperature resistance,thermal stability and plugging performance.The results of displacement test using the dual-pipe parallel mode show that the water plugging agent has the advantages of not only strong selectivity to the plugging layer,but also high scouring resistance.The water shutoff technology of water plugging agent has been applied for 5 times in the field,and the application results have proved that it has achieved good oil well plugging and profile control effect,which can provide a reference for similar reservoir water plugging technology.
