摘要

摘要: 川中古隆起西北斜坡构造变形复杂，明确其构造变形主控因素并揭示差异构造变形机制对于深化四川盆地构造演化认识和指导油气勘探部署至关重要。本研究以川中古隆起西北斜坡区为研究对象，基于高精度三维地震资料与钻井数据，精细刻画断裂-褶皱构造特征，明确了中下三叠统两套膏盐岩层空间展布特征及其与上覆构造变形之间的耦合关系，揭示了研究区差异构造变形机制。研究结果表明：（1）研究区构造变形具有明显的平面分区特征，北部为褶皱主导变形区，西部为断裂主导变形区，南部为弱变形区；（2）膏盐岩厚度空间分布与上覆地层构造样式存在一定的耦合关系，膏盐岩较厚时发育宽缓盐背斜或前翼突破型紧闭盐背斜，膏盐岩较薄时发育对冲型断层、单冲型断层或小型调节断层；（3）综合考虑膏盐岩层空间分布与造山带向盆地的挤压两个影响因素，提出了“膏盐岩层厚薄-应力强弱”双因素控制下的差异构造变形机制。

Abstract: The northwestern slope of the Central Paleo-Uplift of the Sichuan basin presents complicated deformation features with high-level of structural variation. This research aims to evaluate the controlling factors and reveal the differential deformation mechanism, as it is important for improving our understanding in tectonic evolution and oil/gas exploration of the Sichuan Basin. In this research, the fault-fold structural features were characterized in both section view and plane view by integrating high-resolution 3D seismic data and drilling data. The spatial distribution of two Lower-Middle Triassic evaporite layers was then mapped to identify the control on the structural deformation in the overlying sequences. The differential structural deformation mechanism of the study area was revealed. The conclusions are drawn as below. (1) The faultfold structures present high-level spatial variation, with folding dominated northern area, faulting dominated western area, and weak deformation southern area. (2) Significant relationship was observed between the spatial distribution of evaporites and structural styles of their overlying strata. Open salt anticlines or tight salt anticlines with forelimb breakthrough were developed in areas with thicker evaporites, whereas back-thrust faults, single thrust faults or small accommodation faults were developed in areas with thinner evaporites. (3) By integrating the spatial distribution of evaporites and basinward contraction, geological models of " evaporites’ thickness and stress intensity" were proposed to reveal the differential structural deformation mechanism of the study area.
