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1 0. 4 1%~1 4. 2 9%。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 灢 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8 8. 1 4%。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.

Key words: Surfactant,    ,  Low permeability,    ,  Damage of water lock,    ,  Optimize,    ,  Reservoir protectionc
