摘要: 东西伯利亚盆地和塔里木盆地皆为古老的克拉通盆地,都发现有一系列的油气田,只是规模有别。通过油气成藏要素及其主控因素的对比研究发现,塔里木盆地和东西伯利亚盆地在寒武系盐下都发育了优质的烃源岩和储集层,而区域性分布的中寒武统膏盐岩是良好的盖层。根据寒武系的生储盖组合、构造发育、沉积环境以及油气显示情况,并对比东西伯利亚盆地油气田油气成藏的特点认为,塔里木盆地寒武系盐下具有良好的勘探前景,有利勘探区带主要为塔中主垒带及其两侧、塔北隆起的英买力及轮南地区、巴楚低凸起的南部构造带。

Abstract: East Siberia basin and Tarim basin are all ancient craton basins where a series of oil-gas fields have been found, with different scales and reserves. The correlation of hydrocarbon accumulation and major control factors between these two basins indicates that there exist premium source rocks and reservoirs in subsalt carbonate rocks of Cambrian in these basins, and regionally distributing gypsum-salt rock of Middle Cambrian is good cap rock. The study shows that the subsalt carbonate rocks of Cambrian in Tarim basin possess favorable exploration prospect, the favorable areas or zones are located in the main host belts of Tazhong uplift and its two sides, Yingmaili and Lunnan areas in Tabei uplift and southern structural belt of Bachu swell, based on the source-reservoir-cap rock assemblage, structural development, sedimentary environment, oil-gas shows and the petroleum accumulation characteristics of the two basins.

Key words: East Siberia, Tarim basin, Cambrian, subsalt zone, hydrocarbon accumulation
