东北地区复合造山作用与松辽盆地深部找藏方向探讨
Composite orogeny in northeast China and deep reservoir prospecting in Songliao basin
摘要
Abstract
The Northeast China is held by the Siberian plate,the North China Plate and the Pacific plate. Since ancient continental break-up during Proterozoic this area was exposed to Xingkai,Caledonian, Her-cynian, Indosinian, Yanshanian and Himalyanian orogenic activities with accretive and mosaic terrains formed. Composite orogeny in this area is characterized by multi-phase,overriding,structural complexity, long-term process and continental accretion,etc. In late Paleozoic, there was a triangular C-P marine sedimentary basin within the Variscan orogenic belt at northern margion of North China Plate. The current structural frame of the area depends on the structure-magma events during the J3-K1 periods. Oil-bearing basin in the area is genetically related to the "surface-crust-lithosphere three-layered stereo bridge" structural pattern and also to Pacific subduction and asthenospheric mushroom uplift shown by S seismic wave. Due to the complex deep processes of plate collision,compression,underplating,delamination,resorption, thinning,subsidence of crust the composite basin was formed by overprint of Cenozoic continental rift basin on Carboniferous-Permian marine basin. In view of the geological conditions for reservoir-controlling, the main direction and recommendations for future deep reservoir prospecting is proposed.关键词
