| 摘 要： | 通过对中国大中型气田天然气输导通道类型及影响因素研究，得到中国大中型气田主要有断裂、断裂与不整合组合、砂体、断裂与砂体组合、不整合与砂体组合和不整合6种输导通道类型。其中以断裂为主，其次是断裂与不整合组合，再次是砂体和断裂与砂体组合，最少为不整合和不整合与砂体组合。它们主要受盆地类型、盆地内构造带类型和源储空间位置关系的影响。由中国大中型气田储量、含气面积和聚集时问，通过求取其天然气聚集效率，把中国大中型气田划分为高效、中效和低效3类气田。通过中国大中型气田天然气聚集效率与输导通道类型之间关系分析，得到聚集时间相对较晚的断裂、砂体和断裂与不整合组合形成的输导通道天然气聚集效率相对较高，有利于快速形成大中型气田。

| Abstract: | A study on the types of gas transporting pathway and their influence of large and medium gas fields of China suggests that there are six types of gas transporting pathways, i.e. fault, combination of fault and unconformity, sandbody, combination of fault and sandbody, combination of unconformity and sandbody and unconformity. The most important is the fault transporting pathway, the second is the combination of fault and unconformity, the third is sandbody and combination of fault and sandbody, and the last is unconformity and combination of unconformity and sandbody. The types of gas transporting pathway was influenced by the types of basin, types of structures zone in the basin and the spatial relation of source and reservoir. According to gas reserves, gas-bearing areas and accumulation ages of large and medium gas fields in China, and a calculation of gas accumulation efficiency, gas fields of China are divided into three types of high, middle and low efficiency. Through the analysis of relation between gas accumulation efficiency and types of gas transporting pathway, fault, sandbody and combination of fault and unconformity are considered to have higher gas accumulation efficiency, and are favorable for gas to form large gas fields quickly. |
