塔里木盆地西南坳陷苏2构造建模

由于受资料的限制，塔里木盆地西南坳陷苏2构造的构造模型具有多解性，直接影响苏2构造的油气勘探。结合前人研究成果和地质露头、地震、钻井资料，建立起该区带的构造模型，获得以下认识：山前断层为基底卷入断层，断层产状由山前向盆地、由深部向浅部逐渐变缓，泥盆系等较老地层逆冲于苏2背斜之上；苏2构造不但有可能存在下白垩统，而且还可能有侏罗系。

Modeling of Su-2 Structure in Southwest Depression of Tarim Basin

Because of the limitation of information, the Su?2 structural model for southwest depression in Tarim basin is of multiple solutions, which directly affects the exploration potentials of Su?2 structure. Combining with previous research results and geological outcrop,seismic and drilling data, the model for this area is developed, from which the following understandings are obtained: piedmont fault belongs to basement?involved fault, the fault occurrence appears transition from piedmont to basin and from deep to shallow, gradually, the older strata like Devonian system are overlying on Su?2 anticline; the Lower Cretaceous is likely to exist in Su?2 structure, also there possibly exists the Jurassic
