摘　　要：油田开发研究与实践认为 ,水力压裂裂缝延伸方向总是平行于地层最大水平主应力方向或垂直于断层走向。濮城油田沙三段油藏 2 0 0 1年压裂裂缝监测资料显示 ,一半以上压裂井的裂缝延伸方向平行或近似平行于主断层或次级断层 ,重新认识研究后认为这种情况确实存在 ,深入研究其内在原因并提出准确预测压裂裂缝延伸方向的解决办法 。The oil-field development studies think that the extension directions of the crack under the water power pressure always run parallel with the biggest main power of the geologic strata in level or perpendicular to the fault. According to the crack monitor data on the Third Member of Shahejie Formation of Pucheng oil field, the extension direction of the crack in above half well which have been pressed in 2001 is run parallel with or run parallel approximately with the mian or hypo-break layer, and research afresh to think this kind of circumstance are really exsits. deep into its inside reason and bring up the solution that can predict accurately the crack extension direction under the water power pressure, it have the important leading meaning. to instruct development well net in oil-field and put the water power pressure into practice.
