车排子油田地下水特征及勘探领域

对准噶尔盆地西北缘车排子地区各个层系的地层水和原油物理性质进行了分析,认为从石炭系、二叠系、三叠系、侏罗系到白垩系,封闭环境越来越差,其中侏罗系是从封闭环境到开放环境的过渡带,是最理想的储油层位。用地层水型可以判断断裂的封闭性,A 区的侏罗纪是封闭的,而 B 区是开启的。轻质油、中质油、重质油在侏罗系都有分布,表明油源是混源的。分析认为,车排子地区 A 区是侏罗系的主探区域。

Groundwater Nature and Exploration Domain in Chepaizi Field

In view of formation water and crude oil physical properties from all sequences in Chepaizi oilfield of Junggar basin, it is considered that the enclosed environments from Carboniferous to Cretaceous are worse and worse, among which Jurassic is the most perfect oil-bearing reservoir as a transitional zone from enclosed environment to open environment. It is concluded that the formation water type can be used to judge the enclosed quality of fault or fracture. The Jurassic in A zone of Chepaizi oilfield is enclosed and that in B zone is open, so the former (A zone) could be the main target for petroleum exploration in this field.
