准噶尔盆地西北缘构造条件复杂,具有丰富的烃源岩。通过对该区油源和运移通道的分析研究,得出该区油砂的成矿模式:①多期的构造活动使烃源岩多期生烃;②三期构造活动、三个阶段的成矿过程,形成了大量的不整合面和断层通道,使原油远距离运移;③燕山期和喜马拉雅期构造活动使盆地边缘抬升,经受剥蚀,油层出露地表,轻质油逸散形成了现今的油砂资源。该区的油砂资源主要分布在原油运移通道附近。区内油砂总资源量为1.8825×108t,其中可采资源量达1.2603×108t,黑油山背斜附近是油砂资源勘探的有利区。
The northwestern margin of the Junggar Basin is characterized by complex structural conditions and abundant source rocks. Through the analysis of the oil source and migration channel in this area, the ore-forming model of oil sands in this area is obtained: (1) multi-stage tectonic activities make hydrocarbon generation multiple hydrocarbon generation; (3) tectonic activity in the third phase; During the Yanshanian and Himalayan tectonic activities, the edge of the basin was uplifted and subjected to denudation, the surface of the oil layer exposed and the light oil escaping formed the present-day Oil sand resources. The oil sands resources in this area are mainly distributed near the crude oil migration channel. The total resource of oil sands in the area is 1.8825 × 108t, of which recoverable resources amount to 1.2603 × 108t. The vicinity of the Heiyou Mountain anticline is a favorable area for oil sands exploration.
