乾安油田论文：乾安油田储层伤害碱洗返排治理

1、乾安油田论文：乾安油田储层伤害碱洗返排治理【中文摘要】 乾安油田是典型的三低油田，目前油井稳产难度大、靠单一的压裂增油措施无法满足油井稳产的需要，本文结合在认真研 究乾安油田地质状况的基础上，并结合乾安油田在钻井压裂开发过程 存在的问题，进进行了乾安油田的储层伤害机理进行了研究，发现乾 安油田储层泥质含量高，容易造成水敏水锁伤害；油井出水矿化度高，容易结垢堵塞储层；压裂液残渣严重，容易污染储层；原油含蜡量高、 凝固点高,容易造成有机堵塞储层。总之乾安油田储层伤害严重，必须 采取有效治理措施，减少储层伤害。 本文针对乾安油田储层伤害严重，应用裂缝清洗、土酸酸化解堵、强负压复合解堵三项技术，有效减

2、少了钻井、压裂对储层的伤害，恢复油井生产能力，措施增油效果显著，有效延缓了油井综合递减，为乾安油田稳产提供了有效保障。并且提 出碱洗返排技术，减少了酸化、裂缝清洗对环境的污染，减少了残酸对 集输管网及抽油杆管泵的损害，取得了较好的经济效益。本文的研究 成功为低渗透油田增油措施提供了的可靠的依据，具有较高的经济效、人益【英文摘要】Qian an oilfield, which has difficulties inoil well stable production currently and whose requirements of oil wellstableproductioncanno
