摘　　要：对中原油田典型断块地层的造斜规律进行了三维力学分析。并根据分析研究结果，提出了一些行之有效的钻井方法。经５９口斜直井和定向井钻井实践，共缩短钻井周期４３３．６５ｄ，节约钻井成本９４３．４万元，经济效益与社会效益显著。By use of 3-D mechanics analyses, the paper studies the bulidup rules of typical fault block formations in Zhongyuan Oilfield,and puts forward some effective drilling ways. Applications in 59 slant and directionalholes show drilling cycle is shortened by 433. 65 days,and drilling cost is cut down by 9.43 million yuan totally.
