摘　　要：通过对钻井液的筛选和入井液的评价 ,并在室内研究、现场攻关试验的基础上 ,形成了从钻井到完井、采油等区块开发生产全过程中的一整套完善的油层保护技术体系。研究表明 ,钻进过程应采用正电胶钻井液、聚合物铵盐泥浆体系和近平衡钻井 ;作业过程严禁使用淡水或卤水作为洗井液、压井液 ,酸液中应加入抑制盐敏和酸敏的防膨剂 ;压裂过程优选羟丙基瓜胶、有机硼交联剂及微胶囊破胶剂 ;Through selecting the drilling fluids and evaluating the drill-in fluids and based on laboratory study and field test, a complete set of reservoir protection techniques for well drilling, completion and oil production are established in the development of the block. The study shows MMH drilling fluid, polymer - ammonium, salt mud systems and near balanced drilling during well drilling, fresh water or salt water used as a flushing fluid, or killing fluid are avoided during the operation, an antiswell agent is added in acid for inhibiting salt sensitivity and acid sensitivity, during the fracturing, hydraxypropyl melon gum, organic boron cross-linking agent and microcapsule gel breaker are chosen, during water injection the techniques of precision water treatment and prior antiswelling are deployed.
