摘要
塔河油田奥陶系碳酸盐岩油藏经多轮次周期注水后,井间形成优势水流通道,注入水突破现象日益突出,注水效率逐年降低。针对注水突破技术难题,高温(140℃)高矿化度(24×104mg.L-1)作业环境,开展调剖体系室内实验研究,优选分散剂、固化剂、缓凝剂,形成可固化废弃泥浆调剖体系配方,并进行现场试验,调剖效果明显,不仅实现废弃物资源化利用,而且对塔河缝洞型油藏调剖有一定的指导意义。
After multiple water injections for Tahe Oilfield Ordovician carbonate rock, the problem of injection breakthrough is increasingly prominent which lead to lower efficiency. The experiments of profile control system was studied in order to breakthrough the technical problems under the environment of high temperature and high mineralization of water. The dispersant, curing agent and retarder were optimized to form a solidified profile control system formula. The profile control effect was good in field test. The system is not only for waste resources utiliza-tion, and but also guide for profile control of fracture-cave oil deposit.
