摘　　要：准噶尔盆地西北缘、腹部、东部,现已出现3条北东-南西向(或近南北向)展布的油气富集带;在胸部、南缘,可能还会出现2条近东西向展布的油气富集带。这些油气富集带的出现与分布,是与盆地基底存在着具有网格状深大断裂带紧密相连的,特别是近南北向的深大断裂具有拉张和走滑性质,是盆地下“地震活动带”,构成了油气和深部热物质由南向北运移的“高速公路”,盆地盖层在这些地带也正是断裂发育带。已知的原油和地层水分析资料,从不同侧面都支持这个观点。根据这种思路,提出了今后的勘探对策和建议。Three hydrocarbon-enriched belts to northeast-southwest have occurred in northwestern margin, hinterland and eastern part of Junggar basin, and two belts to near-east-west trend are probable to shape in hinterland and southern margin of Junggar basin. Their formation and distribution are closely related to presence of fenestral and deep faulting （s） in the basinal basement. Particularly, the deep faulting to near-south-north trend is characterized by tensional and strike-slip natures, being as “earthquake active zone” under the basin and shaping a “highway” of the hydrocarbon and deep thermal material migration from south to north. The cap rocks of the basin in these belts could be all as fracture-developed zones. These viewpoints have been supported in many aspects by analysis data from available crude oil and formation water. Based on Such a viewpoint, the countermeasures and suggestions for petroleum exploration in the future are proposed in this paper.
