| 摘 要： | 对大庆低渗透储层机构特征和综合损害机理进行研究,确定水锁损害是最主要的伤害类型之一。大庆油田龙西地区水锁损害在10.41%~14.29%。通过在室内对水锁损害机理分析,进行了防水锁剂的优选和评价,优选出的表面活性剂DW-3大大的降低了滤液界面张力,具有良好的防水锁效果。防水锁聚合物钻井液在现场试验表明,矿场评价该钻井液体系渗透率恢复值达到88.14%。形成大庆油田低渗透储层防水锁专项技术,达到保护油气藏的目的。

| Abstract: | The low permeability reservoir characteristics and overall damage mechanism in Daqing were studied , water blocking damage is one of the most important type of injury .By reservoir damage mechanism analysis ,Daqing oilfield Longxi area water blocking damage between 10 .41% ~14 .29% .Therefore ,this paper mainly through water lock damage mechanism indoor ,preferred and evaluation of waterproof lock agent .Optimizing and evaluating anti-water lock agent indoors ,anti-water lock agent DW-3 greatly reduce the filtrate interfacial tension .Anti-water lock drilling fluid ,which was used in field test shows that ：Pilot evaluated the permeability recovery value of drilling fluid system reached 88 .14% .Formed the special technology of anti-water lock in Daqing oilfield ,achieved the purpose of protecting reservoirs . |
