| 摘 要： | 临清坳陷（东部）煤炭资源丰富，石炭二叠系煤系烃源岩埋藏深、分布广，是煤成气勘探的有利地区．自其沉积以来经历了均衡、停止、补偿和差异演化四个阶段，形成了现今比较复杂的热演化格局．按照不同地区的埋藏历史，可以把它们划分成回返型和中隆新凹型两种，后者是煤成气生成和保存的有利地区．结合埋藏热演化史，对临清坳陷（东部）石炭二叠系煤系烃源岩主生气期进行了确定，并计算了其资源量

| Abstract: | The coal is rich in eastern Linqing depression. The burial depth of hydrocarbon source rock is deep, and distribution is broad. It is the best area to explore the gas from coal bed. It underwent through four stages: balance, stop, difference and compensate. According to the history of occurrence of different area, every stage is classified as two types. It is a good area where the burial depth is deep. The period of secondary generation of nature gas is defined, and the gas from coal bed resource extend is estimated. |
