准噶尔盆地西北缘哈拉阿拉特山地区构造特征复杂,地质结构认识不清。依据地质露头、钻井、三维地震及非震等资料,运用地震属性分析、综合标定等技术方法,以断层相关褶皱理论为指导,采用“复杂构造带综合建模技术”构建了“多期逆冲推覆+走滑”构造解释模式。依据此模式,将哈拉阿拉特山前构造纵向分为上下两大构造层;平面上分为前缘冲断带、逆冲叠加带和后翼走滑带3个构造带;整体上划分为前缘超剥带、前缘冲断带、准原地叠加系统及外来推覆等四大系统。根据新的解释成果,在推覆体上部署的hs2井见到工业油流,说明“复杂构造带综合建模技术”在复杂构造建模中具有较好的应用价值。
The structural features of Hala’alat Mountain in the northwestern margin of Junggar Basin are complex and its geological structure is not well understood. Based on the geological outcrops, drilling, 3D seismic and non-seismic data, using seismic attribute analysis and comprehensive calibration techniques, and using the theory of fault-related fold as a guide, a multi-purpose integrated structural modeling technique is used to construct a multi- Periodic thrust nappe + slipping “structure interpretation mode. According to this model, the longitudinal structure of the Hala’alat piedmont is divided into two structural layers, the upper and lower tectonic strata. The plane is divided into three tectonic belts: thrust belt, thrust belt and back wing strike zone; The front edge of the stripping zone, the front edge of the thrust belt, quasi-original superimposed system and the external push the four systems. According to the new interpretation results, the industrial oil flow is seen in the hs2 well deployed on the nappe, indicating that ”the comprehensive modeling technology of complex structural zones" has a good application value in complex structural modeling.
