摘    要:鲁克沁构造带稠油油藏主要为次生油气藏,原油本身低熟,加之成藏过程中多种原因造成轻质组分逸散,进一步稠化而成。该构造带位于库木凸起前缘,长期处于有利的油气指向部位。台北凹陷二叠系桃东沟群湖相泥岩为长期稳定的油气来源。同时,该构造带断层和不整合面非常发育,为油气运移聚集提供了良好通道。通过对该构造带油气运聚规律的认真研究和总结,概括出次生稠油油藏的成藏模式,对吐哈油田下一步对浅层稀油、浅层气、深部气及深部凝析油的勘探具有重要意义。

关 键 词:次生稠油  稠油成因  成藏条件  油藏类型  成藏模式

Abstract:The Lukqun structural belt is located on the leading edge of the Kumu uplift, a favourable area for the hydrocarbon accumulation in the Tainan area, Turpan-Hami Basin, Xinjiang, where the heavy oil reservoirs occur as secondary oil reservoirs. The crude oil with low maturity was graded into the heavy oil due to the bleeding of light components during the hydrocarbon accumulation. The lacustrine mudstones have contributed to the steady hydrocarbon sources from the Permian Taodonggou Group in the Taibei depression. The highly developed faults and unconformities have provided good channels for the oil and gas migration and accumulation. The models for the accumulation of secondary heavy oil reservoirs proposed in this study may be significant to the future exploration of supergene light oil and gas, and deep-seated gas and condensate oil in the Turpan-Hami Basin.
Keywords:secondary heavy oil  origin of heavy oil  hydrocarbon accumulation  type of oil reservoirs  model for hydrocarbon accumulation
