通过油气包裹体的研究 ,对准噶尔盆地腹部石西油田油气藏成藏期次进行了划分 :1侏罗系油藏为一次成藏 ,充注低熟油气 ;2石炭系油藏为多期次成藏 ,主要充注高熟油气。结合区域地质演化特征对油气藏成藏序列分析得出 :来源于二叠系烃源岩的侏罗系油气藏为次生油气藏 ;石炭系油气藏为原生油气藏 ,二者之间有成因关系
According to the study of hydrocarbon inclusions, the hydrocarbon accumulation stages of Shixi Oilfield in the abdomen of Junggar Basin are divided into: 1 Jurassic reservoir is a reservoir formation, filling low-mature oil and gas; 2 Carboniferous reservoir is multi-stage Accumulation, the main charge of mature oil and gas. According to the regional geological evolution characteristics, the sequence analysis of reservoir formation shows that the Jurassic reservoir derived from the Permian source rocks is a secondary reservoir, and the Carboniferous reservoir is a primary reservoir, with the genesis relationship
