摘　　要：针对常规水基钻井液存在的问题,研制出了一种由水、多功能处理剂和可溶性盐组成的新型水基钻井液,多功能处理剂提供所需的钻井液性能,可溶性盐提供所需的钻井液密度。该钻井液组成简单、维护方便,具有较好的流变性和滤失性能,封堵能力强、抑制性好、固相含量低、无污染、适应性广、易配制、可重复利用,是一个全新的钻井液体系。A new water based drilling fluid was designed with water, multi-function additive and soluble salt. The rheology and filtration properties are obtained by the use of the multi-function additive and salt is used to weigh the fluid. This fluid has a simple formulation and is easy to use. Moreover, this fluid can be re-used for several times. Filed application showed its advantages over the previously used water based drilling fluids.
