| 摘 要： | 羊塔克油气田位于塔里木盆地塔北隆起轮台凸起西端 ,由 4个凝析气藏和 2个挥发性油藏组成 ,具有高孔隙度、高渗透率储集层 (白垩系砂岩、下第三系底砂岩 )、优质盖层 (下第三系膏泥岩 )和优越的圈闭条件 ,烃源岩为库车坳陷的侏罗系煤系地层。据油气生物标志化合物参数及稳定碳同位素组成特征分析 ,原油为煤系泥岩生成 ,天然气为煤成气。圈闭形成于早第三纪末 ,油气藏形成于晚第三纪的上新世库车组沉积期。油气从油气田东部注入 ,由东向西运移并差异聚集 ,依次形成凝析气藏、带油环凝析气藏和挥发性油藏。图 3表 3参 2 (梁大新摘 )

| Abstract: | Yangtake oil field, located in Tabei uplift, Tarim basin, consists of two volatile oil pools and four condensate pools. Hydrocarbon accumulation took place in Neogene period, hydrocarbon came from Jurassic source rock. Oil and gases, charged east, migrated and entraped differentially, formated successively condensate pools, condensate pools with oil rings and oil pools. The Jurassic coal measure strata are confirmed to be main source rocks in Kuqa depression. Cretaceous sandstone and Eogene mudstone are the main reservoir and caprock. The traps, formed before Neogene, are favorable for hydrocarbon accumulation. |
