摘　　要：中原油田是一个埋藏深、含油气层系多、油藏类型多、非均质性严重的断块油气田。 1 999年以来 ,大斜度、大位移、高密度定向井逐年增多 ,成为获得油气层的主要方法。从现场角度分析了这类井对钻井液的要求及钻井液技术措施 ,筛选出适合不同区块地层特点的正电胶聚合物混油、聚磺盐水混油、钾铵基聚磺混油钻井液 ,均能满足这些高难度井钻井施工的要求。Zhongyuan Oilfield is a high burial depth,high oil layer and types and inhomogeneous block faulted oilfield.208 directional well had been completed in 1999,These were about 26% in all completed well.High angle and displacement and high density directional well have gained tendencyly every year .In this article,the drilling fluid measures and requirments had been analysed in onsite angle.Electropositive glue polymer drilling fluid (polymer sulphatedand potassium and ammonium base )oil emulsion drilling fluid all can meet the requirement of these high difficulty well.
