摘　　要：可降解钻井液通过在钻进过程中能够对储层实现有效封堵,钻进完成后又可采用破胶剂进行破胶,可对油气储层起到有效的保护作用。UltraFlo是一种塑性粘度低,悬浮性能好的无固相弱凝胶钻井液,通过实验对比数据的对比确定该钻井液体系的处理剂加量,并对该钻井液的各种性能进行了评价,证明其能够较好的保护储层和具有良好的抗温性能。The degradable drilling fluid can effectively block the reservoir through the drilling process and the breaker can be used to break the rubber after drilling, which can effectively protect the oil and gas reservoir. Ultra- Flo is a kind of non solid and weak gel drilling fluid with low plastic viscosity and good suspension performance. Through the comparison of the experimental data to determine the drilling fluid system of the treatment agent, and the performance of the drilling fluid were evaluated. It is proved that it can better protect the reservoir and have good temperature resistance.
