摘要
通过柴达木盆地三湖地区第四系生物气的资源分布类型和控制因素分析,指出生物气具有3种赋存方式:一是聚集在低幅度构造圈闭;二是聚集在岩性圈闭中;三是以水溶性天然气形式广泛分布。北斜坡、盐湖—哑巴尔、西部及凹陷的低幅度构造圈闭是近期的勘探重点,南北斜坡带的岩性尖灭带圈闭、盆地内沉积低隆起带及斜坡带与湖盆内透镜体等岩性圈闭类型是今后的勘探方向,水溶性天然气是第四系探索领域。
From analysis of resources distribution types and controlling factors of Quaternary biogas in Sanhu region in Qaidam Basin,three occurrence ways of biogas are pointed out:the low-rate structural traps,the lithologic traps,and the widely distributed water-soluble form.The exploration focus is the North Slope area,the Yanhu-Yabaer area,the low-rate structural traps in the west and sags.The lithologic pinchout traps in the S-N slopes,the low uplifts and slopes in the basin,and the lens in the lake basin are the future exploration targets.Water-soluble natural gas exploration is heuristic exploration direction in the area.
