论断层面正应力变化及影响因素──复杂断块油气田形成条件系列论文之一

Discussion on the Change of Normal Stress on Fault plane and Its Influence Factors──Part 1 Forming Conditions of Complicated Fault-Block Oil Fields

本文讨论断层面所受正应力的影响因素，包括断层发生时地应力类型，破裂前后、活动期中和构造力消失后埋深变化等因素的影响。并用设定条件对断层在产生以后的发育过程中以及停止活动后正应力的变化情况作了概念性的描述。

This paper discusses the influence factors of normal stress on fault plane,including ground stress types as fault occured and the change of buried depth around crackinghappening, the period of activity, after tectonic stress disappearance, etc. It describesconceptually the change of normal stress during and after the course of fault grouth under theassumed conditions.
