摘　　要：塔里木盆地塔河油田是中国第1个古生界海相亿吨级大油田。结合高精度三维地震精细解析、相干属性提取等方法,从剖面样式和平面展布特征探讨了走滑断裂的构造样式、主次级断裂关系、活动期次及其油气地质意义。研究表明:塔河地区主要发育NNW向和NNE向2组主干走滑断裂,在深层T 7 6界面附近还发育NNW向、NNE向和近EW向3组次级走滑断裂,次级走滑断裂发育层位与塔河油田主要的产油目的层位具有明显对应关系;喜马拉雅期活动强的主干走滑断裂及其与次级走滑断裂交汇部位为油气有利勘探区域。该认识可为该区优选高效井井位和提高钻井成功率提供参考和理论依据。The Tahe Oilfield in Tarim Basin is the first Paleozoic oilfield with a billion-ton scale in China.Combining with the high-precision 3D seismic interpretation,coherent attribute extraction and other methods,the structural styles of strike-slip faults,primary-secondary fault relationships,active stages and its geology significances were discussed from the longitudinal and lateral distributions.Result indicates that there are two groups of major strike-slip faults with NNW and NNE in Tahe.There are also three secondary faults with NNW,NNE and near EW in the vicinity of the deep T 7 6 interface.The horizons with the secondary faults show a favorable correspondence with the major oil production horizons of Tahe Oilfield.The intersection area between the major active strike-slip faults in the Himalayan period and the secondary strike-slip faults is considered as the favorable hydrocarbon exploration zone.This understanding could provide certain reference and theoretical basis for efficient well deployment and well drilling success rate improvement.
