摘要
石炭—二叠纪时,准噶尔地块处于外压内张的构造机制,发育成裂谷型沉积盆地区。二叠系具良好的生油条件,其上为中、新生代地层所超覆,使原盆地边缘的断裂带成为隐伏的古逆冲断裂带。克—乌断裂带向深处收敛可能与达尔布特深断裂组成“Y”形结构,沿断裂带有岩浆侵入和喷出活动。克—乌断裂带,在二叠系、三叠系及侏罗系内,发育了众多不整合、洪积相砂砾岩体、地层剥超带、基岩断块、火山岩等,组成众多的地层及构造圈闭,为油气运移和聚集提供良好的通道和场所,形成大型的隐伏逆冲断裂油气聚集带。本文认为应沿此思路开拓准噶尔盆地新的含油气领域。
In Carboniferous and Permain Period, Junggar Basin was growing a rift depositional basin under the structural mechanism of outside compression and inside tension The Permian System possessed good hydrocarbonforming conditions, and that Mesozoic anti Cenozoic strata overlapped on this strata turned the original fault belts in the basin margin into hidden paleothrust fault belts. It is possible that Karamay-Wuerbe fault belt converged in deep and Dalbute deep fault composed a y-like structure. Along the fault belt, there were magmatic intrusion and extrusion. A lot of unconformities, diluvial sandstoneconglomeratic bodies, stratigraphic denuding and overlapping belts, bedrock fault blocks and volcanic rocks occurred in the Permian. Triassic and Jurassic System in the fault belt formed many stratigraphical and structural traps, which provided good passages and Location for the hydrocarbon migrating and gathering, and formed a large hidden thrust fault hydrocarbon accumulating zone. The purpose of this paper was that new hydrocarbonbearing areas should be developed according to this idea.
