摘    要:近年来针对雪峰山西侧盆山过渡带震旦系-下古生界油气新区新层系所开展的主要油气地质综合调查研究工作及取得的主要进展有:一是综合利用野外地质调查、微古化石和同位素地层测试及以往资料成果,建立完善了震旦系-下古生界统一的多重地层划分对比方案,新建了几丁虫等典型微古化石剖面和同位素地层剖面;二是基本查明区内构造格架和主要褶皱、断裂、滑脱层的分布特征,明确雪峰山主要为准原地构造隆起成因;三是较高精度地恢复了震旦纪-早古生代重点时期岩相古地理面貌及其沉积充填演化序列,揭示了沉积相带对生储岩石发育分布的控制关系;四是更详细地圈定了震旦系-下古生界9个重点层组烃源岩和储集岩的发育分布特征,划分出3套有利生储盖组合;五是解剖总结认为构造抬升和断裂活动是区内及邻区古油藏形成的主要控制因素.其中断裂是决定现今油气保存与勘探选区最重要的因素之一;六是优选出利川-恩施等4个有利含气远景区及2个较有利含气远景区,为深入开展油气勘探目标区优选、实现油气勘探新发现奠定工作基础。

关 键 词:雪峰山西侧地区  盆山过渡带  震旦系-下古生界  油气地质调查  油气远景区

Abstract:The basin-mountain transition zone of westem Xuefeng Mountain,located between Sichuan Basin and Xuefeng Mountain, is a new oil and gas exploration area of Sinian-Lower Paleozoic. This paper focuses on the major progress made by a large number comprehensive hydrocarbon geological survey in recent years: First, the establishment of a more perfect multiple stratigraphic division and correlation program and typical microfossils and isotope profiles of Sinian-Lower Paleozoic, by comprehensive utilization of the latest comprehensive geological survey, microfossils and isotopic formation analysis. Second, to identify basic characteristics of the major folds, fractures, slip layers and tectonic framework of this region,and further confirm that Xuefeng Mountain is a quasi-situ uplift. Third, to restore higher accurate lithofacies palaeogeography and sedimentary filling evolutionary sequences during Sinian-early Paleo- zoic, and designate multiple reef facies belts. Fourth, more detailed delineation of favorable source rocks and reservoirs zone of Sinian- Lower Paleozoic nine key layer group. Fifth, by anatomical think that tectonic uplift and faulting of the region and adjacent areas of ancient reservoirs are main controlling factors formed by ancient reservoirs, especially fracture is the most critical factor in the decision of nowadays oil and gas preservation and exploration. Sixth, Sinian-Lower Paleozoic in the area divided into three sets of favorable combination of reservoir, preferably four favorable hydrocarbon prospective areas. The work has laid an important basis to promote to carry out on and gas exploration target area preferred and new discoveries of oil and gas exploration in the area.
Keywords:west side of Xuefeng Mountain  mountain-basin transition zone  Sinian-Lower Paleozoic  comprehensive hydrocarbon geological survey  hydrocarbon prospective area
