本文介绍了堵水调剖剂GD MB的室内研究与现场应用。GD MB堵调剂由生物钙粉、矿物粉、固化剂等组成 ,配制成可携带、易泵注 ,在一定温度条件下可反应生成高强度凝结体的悬浮浆液。凝结体在 70℃温度条件下可稳定存在 6个月以上 ,其抗压强度大于 1 .0MPa。该堵调剂对岩心的堵塞率大于 98% ,对岩心孔隙具有很强的封堵能力 ,适用于高含水油田油水井堵水调剖 ,已用于胜利孤岛油田 5口注水井的调剖 ,取得了明显效果。
This paper introduces the indoor research and field application of plugging water control profile GDMB. GD MB blocking agent consists of biological calcium powder, mineral powder, curing agent and other components, formulated as a portable, easy to pump injection, under certain temperature conditions can generate high strength condensate suspension slurry. Condensate at 70 ℃ under the conditions of temperature can be stable for more than 6 months, the compressive strength is greater than 1 .0MPa. The clogging agent has a plugging rate of more than 98% for core and strong plugging capability for core porosity. It is suitable for water plugging and profile control of oil and water wells in high water cut oil fields and has been used for profile control of five water injection wells in Shengli Gudao Oilfield. Obvious effect.
