苏南、浙北地区叠层复因多期层滑构造及其与油气藏的关系

我们将层间滑动—切层滑动—逆掩断层—推覆构造这—滑动构造系列称之谓层滑构造。苏南浙北地区地壳浅部的层滑构造有六个层位叠复发育,有水平挤压和重力滑动各种成因,有印支期和燕山期多期活动。层滑构造产生叠复盆地,有利于油气藏的形成和保存。需强调的是构造应力活动同油气运移是密切相关的。

POLYGENESISES AND MULTIPLE-PERIODS LAYER SLIDING STRUCTURES WITH SUPERINCUMBENT-BEDS AND THEIR RELATION WITH OIL-GAS POOL IN THE AREA OF SOUTHERN JIANGSU AND NORTHERN ZHEJIANG

We call a system of sliding structures, including bedding slip-dessecting slip-overthrust-nappe structure, as the layer sliding structure. There are six superincumbent beds, characterized by various genesises of horizontal compression and gravitative sliding, and multiple-cycle activities Yinzhi and Yenshan are in the layer sliding structures developed in the shallow crust in southern Jiangsu and northern Zhejiang. A superim position basin is produced by the layer sliding structure, and this basin is beneficial to the formation and preservation of oil and gas. It should be stressed that activities of structural stresses are closely related to the movement of oil and gas.
