| 摘 要： | 依据近几年新疆区域地质调查结果,结合新疆油田与吐哈油田最新勘探成果,通过区域构造背景和沉积充填演化特征推断石炭系沉积建造样式,理顺了新疆北疆地区石炭纪地层层序,目的是推断石炭纪烃源岩发育层段与主力生烃区范围。下石炭统有效烃源岩分布较广,主要发育于北疆西准噶尔达尔布特山前、博格达山前、准噶尔东部陆东—五彩湾地区早石炭世被动陆缘海相和海陆过渡相沉积盆地;上石炭统有效烃源岩分布相对局限,主要发育于东准噶尔克拉美丽山前石钱滩区、布尔津—吉木乃区及库普—三塘湖区海陆过渡相沉积盆地内。石炭系油气成藏严格遵循"源控论",有效生烃区决定其有效成藏范围,所伴随发育的火山岩体决定其富集程度。优选西准噶尔、东准噶尔、库普—三塘湖区、博格达山前区、布尔津—吉木乃区石炭系烃源岩发育区及其相邻构造带,作为今后石炭系油气勘探战略选区的重要领域和区带。

| Abstract: | According to the results of regional geological survey in recent years and the latest exploration achievements of Xinjiang & Tuha oil fields,the Carboniferous sedimentary building patterns by the analysis of regional tectonic background and depositional filling process are concluded.The aim of this article is to clarify the Carboniferous stratigraphic sequence in northern Xinjiang and to point out the source rock-existing formations of Carboniferous as well as the main hydrocarbon generating areas.The effective source rocks mainly occurred in the marine sedimentary basins of passive continental margin and marine-continental transitional facies basins developed during extensional period of Early Carboniferous in the Derbute Piedmont,Bogeda Piedmont in west Junggar,and east Junggar basin-Wucaiwan district,and were widely distributed in Lower Carboniferous;on the contrary,these rocks in Upper Carboniferous were relatively limited distributed,which existed mainly in the Shiqiantan and Buerjin-Jimunai and Kupu-Santanghu marine facies basins of Kelameili Piedmont in east Junggar basin,respectively.Hydrocarbon accumulation process in Carboniferous strictly followed the "Source Control Theory".Effective hydrocarbon generating areas controlled the effective hydrocarbon accumulation areas,whose enrichment degree was affected by associated volcanic rocks.Finally,we selected several important regions that are strategic areas for the oil & gas exploration of Carboniferous.These regions included the developed source rock area and the adjacent tectonic belts in the east and west parts of Junggar basin,the Kupu-Santanghu area,the Bogeda Piedmont and Buerjin-Jimunai. |
