挤压盆地中背斜油气成藏模式——以柴达木盆地七个泉油藏为例
|
摘要
以柴达木盆地西部地区七个泉构造为例,借助岩心薄片观察、物性及地震解释,提出了背斜构造带中烃类初次运移方向主要为顺层面侧向运移,并在背斜核部深层聚集,随后沿裂缝等路径向浅部储层分散.油藏分布具有深部大、浅部小的特点,为挤压盆地中背斜油气藏的勘探开发提供参考.
Based on core and thin section observation,physical property analysis,and seismic interpretation in Qigequan area in western Qaidam,a new hydrocarbon accumulation mode in the anticline structure is proposed.Hydrocarbon moves mainly along the parallel direction in the wing and the crack in the axes.Hydrocarbon fills first the deep strata and then the shallow formation in the axes.
