| 摘 要： | 春晖油田侏罗系八道湾组油层段为中砾岩、细砾岩及含砾砂岩构成的一套粗碎屑沉积,储层非均质性较强,物性与含油性密切相关。为了确定优势储层的发育方向与分布,利用重矿物法和地层倾角法对物源方向进行了研究。重矿物中ZTR指数自西北向东南方向由5增大至20以上,反映出沉积物的搬运方向为西北→东南。18口井的倾角矢量图中矢量点最多的方向也均指示为东南方向,最终确定物源为西北方向的哈拉阿拉特山,同时对近源砾石较高的磨圆度进行了分析。

| Abstract: | The oil reservoirs in the Jurassic Badaowan Formation in the Chunhui Oil Field,Junggar Basin are mainly built up of a succession of coarse-grained clastic deposits including medium-to fine-grained conglomerates and gravelly sandstones.In this study,the provenance analysis is based on the heavy mineral method and stratal dip logs to determine the orientation and distribution of the dominant reservoir rocks.The NW-SE-trending increase of ZTR indices in the heavy minerals shows a NW-SE-trending migration of sediments,as indicated by the dip logs for several wells and the roundness of the proximal gravels in the Badaowan Formation.It follows that the principal source of detritus lay to the Halaalate Mountain in the northwest. |
