研究表明,本區石炭?二疊紀烴源巖在中生代發生一次生烴和排烴,並有油氣充注,后因燕山運動導致地層抬升,一次生烴和成藏過程中止;在早第三紀,原來東傾的地層變為西傾,斷塊圈閉開始具雛形;至早第三紀沙二末期,石炭?二疊系的大部分地層古地溫再次超過中生代一次生烴的溫度,開始二次生烴和排烴,圈閉持續發育;晚第三紀末?第四紀,二次生烴、排烴達到高峰,二次成藏完成。Thus, it can be clearly recognized that the global continents located at near equator and southern hemisphere, showed the characteristics of range along latitude ; chinese continental blocks still located among the laurentia, siberia and gondwana in paleozoic ; following the fast moving of siberia plate to northwards, the amalgamation in north - south direction at the western parts of laurentia and gondwana, subducted the lapetus and rheic oceans, until to form the uniform pangea in the late stage of paleozoic ; however australia and india plates in eastern gondwana move and disperse gradually to southwards, to extend crust and form the paleo - tethys ocean ; the chinese continental blocks and adjacent blocks still located in paleo - tethys ocean, preserved the status of dispersion, gradually moving to northwards, showed the characteristics of range along north - south orientation, until carboniferous and triassic a series of local collisions happened in tianshan - hing ' anling, kunlun, qinling - dabie, jingshajiang and shaoxing - shiwandashan zones, thus the most part of chinese continental blocks amalgamated to eurasia continent
由此可以清晰地看出,在古生代早期全球各大陸的主要部分都位於赤道附近及南半球,大致表現為沿緯度、呈東西向排列的特徵,中國及鄰區的小陸塊群在古生代始終都處在勞倫大陸、西伯利亞與岡瓦納大陸之間;隨著西伯利亞大陸的快速北移,在勞倫大陸與岡瓦納大陸的西部地區發生南北向拼合,亞皮特斯洋和里克洋的消亡,到古生代晚期形成統一的泛大陸;而岡瓦納大陸的東部(澳大利亞和印度等)則逐漸向南移動、離散,地殼張開,構成古特提斯洋;中國及鄰區的小陸塊群則一直處在古特提斯洋中,保持離散狀態,總體上緩慢地向北運移,並逐漸轉為近南北向的排列方式,石炭紀到三疊紀才在天山興安嶺、昆侖山、秦嶺大別、金沙江和紹興十萬大山等地段發生一系列局部性的陸陸碰撞,使中國大陸地塊的大部分逐漸併入歐亞大陸。In the late permian and triassic, the basin underwent once again a large - scale transgression, and the depositional environment was shelf sea with delta locally

討論了查干凹陷及鄰區中-新生代盆地構造演化及其地球動力學特徵,三疊紀(印支期)為陸內造山作用與地殼增厚、隆升剝蝕階段;侏羅紀(燕山早期)為造山後造山帶的局部伸展垮塌階段;白堊紀(燕山晚期)為造山期后大規模伸展垮塌作用與伸展盆地的發育階段;新生代(喜山期)為遠距離碰撞效應與弱擠壓撓曲性質的穩定大陸內坳陷的發育階段。Firstly, based on the basin prototype, the triassic and jurassic mudstone and coal, the main source rocks of the basin, did not develop better in baicheng sag than in the northern thrust belt including keyi structural belt ; secondly, because of the thrusting happened in late cenozoic, the triassic and jurassic source rocks reach to a high to over high maturity and thus generate gas or condensate oil mainly. thirdly, the thrust faults compelled the natural gas to migrate from the north to the south or from the deep to the shallow. as a result, the keyi structural belt and the eastern qiulitage structural belt enriched in natural gas because they were not only located on the migration routines of the natural gas, but also developed simultaneously when the gas migration happened
從盆地構造史研究的角度認為庫車盆地的天然氣主要來源於北部山前沖斷帶: 1受原型盆地構造格局的制約,三疊系侏羅系烴源巖發育的最有利位置不是在拜城凹陷,而是在克依構造帶及其以北的北部山前沖斷帶2晚第三紀以來的逆沖推覆作用使得烴源巖提早進入高過成熟階段,並以產氣和凝析油為主3逆沖推覆作用所產生的北傾逆斷層控制天然氣自下而上自北而南運移,位於運移路線上的克依構造帶和秋里塔格構造帶的東段與烴源巖的排氣期匹配較好,從而使這些地區最富集天然氣。During my master " degree investigation, i mainly focused on the coarse - grain stratigraphy within mesozoic basins in chengde and pingquan districts, the eastern yanshan, and did systemic provenance analysis and paleo - current direction measurement and studied the relationship among basin evolution, volcanism and tectonism. then i summarized the mesozoic basin development and the coupling characters of basin and mountain. the evolution of basin and mountain in this area can be divided into several stages : the stage of compression uplift and flexural basin during the triassic through the early jurassic, the stage of structural compression - volcanism and foreland basin during the middle and late jurassic and the stage of rift basin in the cretaceous
