| 摘 要： | 川南地区断层带提供了天然气向上散失通道，并破坏盖层封堵能力。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。利用数量化理论建立了断层带不同部位缝洞系统保存系数的定量预测模型，可用于大断裂带保存条件的钻前预测。

| Abstract: | The faulted zones in South Sichuan serve as up escaping paths of subsurface gas and destroy sealing property of cap rocks. 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. The quantitative approach to appraising preservation conditions of the fracture cavity system in the faulted zone before drilling has been put forward. |
