源外远源油气藏的内涵和特征——以准噶尔盆地盆1井西富烃凹陷为例
|
摘要
中国西部复杂叠合盆地主要发育多源多期的源外油气藏,可将其划分为源外近源油气藏和源外远源油气藏。虽然源外远源油气藏国内外勘探实例较多,但对其内涵和特征描述却不多见。为此以准噶尔盆地盆1井西凹陷为例,围绕"源、输、圈"三者之间的时空耦合关系,从动态成藏角度分析了凹陷北侧源外远源油气藏的特征及成藏规律,认为其具有远离生烃中心,在源输体系内油气单次或多次远距离聚集,且成藏期滞后于大规模排烃期等内涵特征。在油气二次运移或次生调整时期,源输体系与体系内圈闭的有效时空耦合是源外远源油气成藏的关键认识基础上,结合不同成藏时期及成藏构造带的形态变化规律,可将源输体系划分为稳定型和变迁型源输体系2类,变迁型源输体系又可细分为建设性变迁型源输体系和破坏性变迁型源输体系。研究指出基东鼻凸带两翼、陆梁隆起南翼、石南31至石西低凸带、盐131低凸带及侧翼值得下步远源高效勘探更多的关注。
The complex superimposed basins mainly developed outside hydrocarbon reservoirs in western China with the characteristics with multi source and multi stages,which can be divided into near source and far source.There are a lot of exploration examples of far-source reservoirs outside the source at home and abroad,but the description of the connotation and characteristics is not much.Taking the Well Pen-1 west sag of Junggar Basin as an example,based on the analysis of the space-time coupling relationship of "source,carrier,trap",we analyzed the reservoir characteristics and pool formation patterns of the farsource reservoirs in the north of Well Pen-1 west sag from the perspective of dynamic accumulation.The research suggests that connotation characteristics include a farther distance from hydrocarbon-generating center,a single or multiple oil and gas long distance accumulation in"source-carrier"system and reservoir forming period lagging behind.According to crucial point of the effective coupling between the source and transportation system during the oil & gas secondary migration or adjustment,the source-transportation system can be divided into two types:The stable source-transportation and the transitional source-transportation combined with the structural characteristics of different oil & gas accumulation stages.The transitional source-transportation can be subdivided into constructive and destructive source-transportation.The further oil/gas exploration of far-source reservoirs in Well Pen-1 west sag should be focused on the flank of the Jidong nose convex belt,the south Luliang uplift,the low convex belt between the SN31 area to the Sixi area,the low convex belt and the flank of the Y131 area.
