摘要
通过分析斋桑盆地东部萨尔布拉克地区天然气有机地球化学特征,全面解剖气藏形成的地质条件,认为该区天然气为二叠系和侏罗系稠油的生物降解气,属于晚期或超晚期成藏。指出该区原油生物降解气资源量大、丰度高、勘探潜力大,喜马拉雅运动期形成的一系列背斜、断背斜等圈闭是天然气勘探的主要目标。
The analysis of the natural gas organic geochemical characteristics and the comprehensive study of the gas reservoirs-forming geological conditions in Sarybulak area in eastern Zavsan basin of Kazakhstan show that the gas in this area belongs to biodegraded gas of the Permian and the Jurassic heavv oils,with gas accumulation occurring in Late Neogene to Quaternary.It is suggested that the biodegraded gas in this area is characterized by abundant resources,high abundance and huge potentials for exploration.A series of anticlinal and faulted anticlinal traps formed during Himalayan orogenic period could be the major targets for natural gas exploration in this area.
