准噶尔盆地西缘春光油田地层-岩性油气藏特征

doi:10.11743/ogg20150302

摘要/Abstract

摘要： 春光油田位于车排子凸起斜坡带上，构造较为简单，油气成藏类型以地层-岩性油气藏为主，属于源外成藏。新近系沙湾组、古近系和白垩系是主要的勘探层系。通过沉积特征研究，认为新近系沙湾组主要发育冲积扇、辫状河沉积，古近系、白垩系主要发育辫状河三角洲沉积。在明确该区地层沉积特征的基础上，开展了春光油田地层-岩性油气藏成藏条件研究。首先通过油源对比分析，认为东部昌吉凹陷和南部四棵树凹陷均具有供烃能力，二叠系和侏罗系是主要的供烃层系。输导条件是春光油田油气成藏的主控因素。对不整合面、厚砂体和断层这3种输导要素进行了深入研究，认为春光油田存在一套高效的复式输导体系，并建立了该区的油气输导模式。分别对新近系沙湾组岩性油气藏和白垩系、古近系地层油气藏特征开展了研究，确定了各个层系油气成藏主控因素，并最终建立了春光油田油气成藏模式，有效的指导了春光油田地层-岩性油气藏勘探。

Abstract: The Chunguang oilfield is located in a simple structure named Chepaizi slope zone in western margin of Juggar Basin, northwestern China.The reservoirs are mainly stratigraphic and lithologic type of outside hydrocarbon source.The Neogene Shawan Formation, Paleogene, and Cretaceous, are all the exploration targets.Analyses of depositional characteristics show that the Shawan Formation developed mainly alluvial fan and braided river depositional system, the Paleogene and the Cretaceous grew braided river delta sedimentary system.A study based on semdimentary features of the area had been carried out to answer questions concerning on reservoiring conditions.Analyses of oil-source correlation show that the Changji sag in the east and Sikeshou sag in the south of the area had the potential to provide hydrocarbon and their Jurassic and Permian formaiotns were the major hydrocarbon-generating ‘factories'.Migration pathways for hydrocarbon were regarded as the major controlling factor for the reservoiring of oil in the area.Three relevent elements had been thoroughly studied(unconformity, sand sheet and fault).The result indicates the existence of a highly efficient pathway system.A hydrocarbon migration pattern was established for the area based on the study.Reserveroi features analyses of the area were used to determine the major controlling factors, establish of reservoring model and guide the exploration.

Key words: oil-source correlation, migration pathway system, reservoiring model, stratigraphic and lithologic reservoir, Chunguang oilfield, Juggar Basin
