摘要
通过CO2气藏中啄13CCO2、CO2含量、CO2/3He、3He/4He等C—He系统分析,确定了花沟地区CO2气藏的成因类型。对高53馆陶组气藏、花17沙三段气藏、花501馆陶组气藏等典型CO2气藏进行了解剖,利用地震、重、磁等资料分析了断裂、火成岩发育特征及其与CO2成藏的关系。根据花沟地区勘探实践,总结了CO2气藏的地震识别方法和地表化探检测方法。
CO2 pool genesis types of Huagou area are determined by systematically performing C—He analysis for ?13CCO2,CO2 content,CO2/3He,3He/4He in CO2 pool. Gao 53 Ng pool, Hua 17 Es3 pool and Hua 501 Ng pool have been anatomized. Growth characters of fault fracture and eruptive rock and their relationships with CO2 pool forming are analyzed by using seismic data, gravity and magnetic data. The seismic identification and geochmical surfacedetection for CO2 pool are summarized based on practical exploration experiences in Huagou area.
