摘　　要：通过研究发现,吉木萨尔凹陷吉7井区侏罗系八道湾组由于地层向东逐渐抬升并受到剥蚀而形成地层圈闭。八道湾组底部砂层发育并与下覆梧桐沟组地层直接接触。芦草沟组烃源岩在流体势的作用下侧向运移并在断裂沟通下油气垂向运移,在梧桐沟组聚集成藏,由于八道湾组地层直接覆盖在梧桐沟组之上加之断裂沟通,形成八道湾组新油气藏。The study found that depression Ji 7 wells Jimusaer Jurassic strata due to the east Badaowan gradual uplift and erosion formed the stratigraphic trap.Badaowan bottom sand under development directly contacts with the overlying Wutonggou Formation.Lucaogou lateral migration of hydrocarbon source rocks and communicate in broken vertical migration of oil and gas in the reservoir Wutonggou group gathered under the action of a fluid situation,because Badaowan directly overlying strata groups combined Wutonggou broken communication,forming Badaowan new reservoirs.
