This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement, whose tectonic deformation and magma intrusion is fiercely, and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian, it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area, such as a - granite ' s stock, batholiths and diabase ' s dike. there are many fault depressions possible
按照不同構造層,研究了各構造層的構造特徵:基底構造層:受早海西期構造作用的影響,與準噶爾洋盆俯沖閉合、而後陸-陸碰撞的區域擠壓構造作用有關,為一構造變形和巖漿侵入活動強烈的古生代褶皺基底。二疊系構造層:受中海西區域性伸展斷陷作用的影響,盆地及其周緣地區發育與伸展構造有關的構造-巖漿組合,如呈巖株、巖基狀侵位的a型花崗巖以及呈巖墻狀侵位的輝綠巖等。The basin - formed mechanism, evolution model and petroliferous geological features of compresso - shear basins in the world are analyzed, by which six aspects of the features are summarized as follows : 1 ) in the compresso - shear process, the sedimentary speed of basin is high, forming thicker coarse - grained clastic rocks which normally shape good petroleum reservoir ; 2 ) the source rocks of basin tend to coming from the organic matter - enriched rocks formed in pre - compresso - shear stages, except that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in pre - compresso - shear stages, e4xcept that in intense compresso - shear process, deep water - semi deep water source rocks are possibly developed in frontal of deep depression ( fore deep ) of thrust belt ; 3 ) the en echelon folds ( including anticline and fault - nose structure ) are generally as good oil traps ; 4 ) the compresso - shear process is helpful to hydrocarbon accumulation ; 5 ) it may promote the maturity and hydrocarbon - generating process of organic matte, and 6 ) the thrust belts in the surrounding areas of compresso - shear basin are favorable are favorable domains for petroleum concentration
摘要通過對世界上壓扭性盆地的成盆機制、演化模式和油氣地質特點分析,總結壓扭性盆地具有6個方面的石油地質特徵:壓扭作用期間盆地的沉積速率較高,一般形成較厚的粗碎屑沉積,它們常構成很好的油氣儲集層:盆地的烴源巖往住來自於前壓扭期砂成的富含有機質的巖石,但在強烈的壓扭作用期間,在沖斷帶的前緣深坳陷(前淵)中有可能發育深水半深水相的烴源巖;壓扭(張扭)作用期間形成的雁行式褶皺(包括背斜和斷鼻等)往住是很好的油氣圈閉;壓扭作用易於成藏;壓扭作用可以促進有機質的成熟生烴作用;壓扭性盆地的周邊沖斷帶是油氣賦存的有利部位。Situated at the both e w sides of pamir, the s w tarim and tadjik basins have the similar evolution history of tectono sedimentary processes during cenozoic, i. e. steady subsidence with transgressive sequence in paleogene and speedy subsidence with continental molassetype sediments in strong compressive tectonic environment in neogene - quaternery. since neogene, for the effect of pamir and west kunlun s northward moving and thrusting, there is complicated tectonostructural deformation taking place in tadjik and sw tarim. neogene stratigraphic combination and later structural deformation of tadjik basin and southwestern tarim much resemble each other in terms of extent of transpressional processes. paleogene in tadjik basin is main oil - bearing sequence and many substantial oil - gas fields there have been found. so, it can be assured in comparison that there is oil - gas perspective also in southwestern tarim region
第四紀受強烈擠壓快速沉降接受陸相磨拉石沉積。自新第三紀以來,受帕米爾西昆侖北移和隆升沖斷的影響,塔西南和塔吉克盆地發生了復雜的褶皺沖斷變形,其差異在於塔西南明顯地受走滑為主的剪壓構造作用,而塔吉克盆地是受擠壓為主的剪壓構造作用的影響。塔西南和塔吉克盆地下第三系巖相組合類似,後期構造變形也相似,塔吉克盆地下第三系是該盆地的主力油層,已有許多油氣田發現,因此可以推斷塔西南也應該有良好的油氣前景。
