摘    要:对济阳坳陷断裂发育特征、断裂对CO2气释放、运移和聚集成藏的控制作用分别进行了分析研究,认为该坳陷多期次、复杂的断裂活动为幔源CO2气的成藏提供了良好运移、聚集条件,幔源无机成因的CO2气自地幔岩浆脱气能够沿着断裂运移到浅层圈闭聚集成藏,其中断裂活动起到了关键的作用,济阳坳陷已发现的八里泊、花沟、阳25等CO2气藏均与周围的断裂活动有关。埕南断裂、临商断裂、高青-平南断裂是济阳坳陷内CO2气运移、聚集成藏的有利断裂,断裂带附近的各类构造和岩性圈闭是济阳坳陷CO2气勘探取得进一步突破的有利目标。

关 键 词:济阳坳陷  断裂活动  气源断裂  运移  聚集  二氧化碳气藏

Abstract:Characteristics of fault development and the control of faults on outgas, migration and accumulation of CO_2 in Jiyang depression are studied in this paper. The complex multiphase faulting in Jiyang depression provided favorable migration and accumulation conditions for reservoiring of mantle-derived abiogenetic CO_2, which migrated upward along the faults and accumulated in the shallow traps. Faulting has played a key role in the process of CO_2 reservoiring. All the CO_2 reservoirs discovered in Jiyang depression, such as Balipo, Huagou and Yang 25, are related with the faulting nearby. Chengnan, Linshang and Gaoqing-Pingnan faults are favorable for migration and accumulation of CO_2 in Jiyang depression. The structural and lithologic traps along these faults are favorable targets for future exploration of CO_2 reservoirs in Jiyang depression.
Keywords:Jiyang depression  faulting  gas source fault  migration  accumulation  CO_2 reservoir
