高邮凹陷横向低凸起构造特征分析
|
摘要
选择发育典型横向低凸起的高邮凹陷作为研究对象,综合利用地震、测井、录井资料分析横向低凸起的空间展布,重构横向低凸起的演化及动力机制,探讨横向低凸起与沉积相的耦合关系。研究结果表明:高邮凹陷断层(系)产状及其联接方式的差异性形成了离散型横向低凸起和汇聚型横向低凸起;在运动学方面,断层的构造演化阶段控制了走向斜坡与横向低凸起的演化程度,但两者的演化阶段并非同步进行;在动力学方面,断层间应力状态的差异形成了倾滑横向低凸起、斜滑横向低凸起和混合横向低凸起3种类型。横向低凸起与三角洲沉积体在时空上呈现良好的耦合关系。
According to the seismic, well logging and mud logging data, spatial distribution of lateral low uplifts was analyzed, the evolution and dynamic mechanism were reconstructed and the coupling between the lateral low uplifts and sedimentary facies was investigated by taking typical lateral low uplifts in Gaoyou sag as research subjects. The results show that it is the difference in fault attitude and its connection mode in the Gaoyou sag that leads to the formation of different types of lateral low uplifts. In the geometry, dispersion inclined hard linkage between the faults forms the dispersion lateral low uplift, and the convergent inclined hard linkage forms the convergent lateral low uplift. In the kinematics, the structural evolution of faults controls the evolvement degree of strike slope and lateral low uplift, but their evolutionary stages are not experienced at the same time. In the dynamics, the difference in stress status between faults can leads to the formation of three types lateral low uplift, i.e. dip slip lateral low uplift, slanted slip lateral low uplift and mixing lateral low uplift. Lateral low uplift and delta depositional system show good coupling relationship between space and time.
