摘　　要：临清拗陷东部CO2资源丰富,在古生界和新近系均发现了CO2气藏。根据最新勘探和研究成果,并结合济阳拗陷与东濮凹陷的勘探实践,分析认为临清拗陷东部CO2气藏气主要为幔源岩浆成因,浅层气藏中可能有煤成气过程中的伴生CO2混入。通过对典型气藏的解剖,指出断裂活动和岩浆活动对临清拗陷东部CO2的成藏有重要的控制作用。结合地质条件,指出了有利的勘探区带。CO2 resources are well developed in eastern part of Linqing Depression,and have been discovered both in Paleozoic and Neogene system.Based on the latest exploration and research achievements,combing with practice in adjacent Jiyang Depression and Dongpu sag,this paper analyzes the genesis of CO2 in eastern part of Linqing Depression,and point out that it is mantle-magma derived CO2,while shallow buried gas may contain associated gas during generation of coal derived gaseous hydrocarbon.Based on the sectional anatomy of typical gas reservoir,it can be concluded that tectonic movements such as faulting and magmatic activity are significant to reservoir forming of CO2 in eastern part of Linqing Depression,and consequently summarized favorable exploration structural belts and CO2 resource potential.
