大断裂影响缝洞系统保存条件的主要因素包括：大断裂断距、断层上消失层位、断面倾角、盖层厚度以及缝洞系统所处断裂带位置等。
The main factors influencing the gas preservation condition includes the fault amplitude, fault fragmented intervals, fault surface dip, and the position of fracture cavity system in the faulted zone.
如果盖层中发育顺层断层，盖层的封盖能力将被大大改善，将能够封盖更大的油气高度或者流体压力，利于形成更大规模的油气藏。
Therefore cap rocks with bedding faults can seal higher hydrocarbon column height and fluid pressure and thus facilitates the formation of larger scale hydrocarbon accumulations.
在同一凹陷中，断层的旋转、滑移运动，生、储、盖层的沉积作用和重力侧向滑动作用同步发生。
In the same depression, the rotation and slide of the fault, the sedimentation of source-reservoir-cap rock and gravity caused lateral sliding take place synchronously.
