| 摘 要： | 综合应用地震、钻井等资料 ,对山东惠民凹陷的伸展构造及调节带特征进行了系统的分析。认为惠民凹陷的总体构造特征是正断层发育 ,构造类型以伸展断块构造 (半地堑和半地垒 )为主。凹陷内一级正断层主要控制着凹陷的沉积和构造特征 ,二级断层控制着构造带(凹陷内的半地垒 )的形成 ,三级及四级断层控制着局部构造的形成或对局部构造起复杂化作用。惠民凹陷具有分区块断构造特征 ,即呈南北分带、东西分块的构造格局 ,纵向伸展断块之间为调节带所调节。分析认为惠民凹陷内发育 2个一级调节带和 5个二级调节带 ,它们多是油气聚集的有利地区。

| Abstract: | According to the seismic and well data, this paper systematically analyzes the structural characters and accommodation zones in the Huimin Depression. The faults develop in this area with several orders, and extensional faulted blocks (half graben and half horst) are the main type of structural style. The first-order faults control the sedimentary and structural characters of the Huimin Depression, the second-order faults control the formation of second-order structure zones, and the third and forth-order faults control the formation of local structures or complicate them. The segmentation of structure pattern is the characteristic for the Huimin Depression. the longitudinal structural zones can be divided from north to south and the transverse faulted blocks can be divided from west to east. Among these structural zones, there exist accommodation zones. Moreover, two first-order and five second-order accommodation zones can be identified in the Huimin Depression, most of which are advantageous zones for oil & gas accumulation. |
