  1. The frontal structure of longmenshan in the west of sichuan is very complex, showing intense structure deformation in overthrust belt, high structure amplitude, steep stratigraphic dip, developed fault blocks, complex seismic wave field, frequent change of lateral velocity, and poor image of post - stack time migration processing

    摘要川西龍門山前緣構造非常復雜，逆掩推覆構造帶構造形變強烈，構造幅度大，地層傾角陡，斷塊發育，地震波場復雜，速度橫向變化大，常規疊后時間偏移處理成像效果較差。
  2. Through the research on the development character of overthrust fault, we analyzed its sealing mechanism. we also established evaluation standard and method of fault sealing ability through the following two simulation experiment : experiment on the quantitative relationship between property of fracture zone filler and fault sealing ability ; experiment on the deformation character of cream shale. based on these work, we evaluated sealing ability of overthrust faults on several typical structure in kuche depression

    本文通過逆掩斷層發育特徵研究，分析了逆掩斷層封閉機理，在斷裂帶填充物性質與斷層封閉性定量關系模擬實驗和膏泥巖變形特徵模擬實驗基礎上建立了斷層封閉性評價標準及評價方法，以此對庫車坳陷幾個典型構造上逆掩斷層垂向封閉性進行了評價，結果表明現今斷層多是封閉的，這是庫車塌陷天然氣和異常孔隙流體壓力得以保存的主要條件。
  3. Based on these research, we recovered the evolution history of overthrust faults vertical sealing ability and considered that there always have fracture activity ever since jidike formation deposition period. but this kind of activity is not always continuous. during moving period, fault is open

    在此基礎上對逆掩斷層垂向封閉性演化史進行了恢復，認為斷裂自吉迪克組沉積時期以來均有活動，但這種活動是間歇性的，活動時期斷層開啟，靜止時期斷層多是封閉的。
  4. We established geological and mathematic model for the relief of overthrust fault and earned out simulation computation after selecting factors. the result is that pressure can be released when fault is open. but ft will take a long time for the formation pressure to be relieved to normal formation pressure

    建立了逆掩斷層泄壓的地質模型和數學模型，選取參數后進行了模擬計算，結果表明逆掩斷層活動開啟釋放壓力，但要將地層壓力釋放到正常地層壓力需要時間較長，在斷裂活動時期不足以將圈閉中超壓釋放掉，這是庫車坳陷超壓能夠保存的另一主要原因。
  5. Nw compressive structures are developed in indosinian epoch in which folds are predominant and companied with some small thrusts. nearly ns or nnw compressive structures are developed at the end of yanshan epoch in which it is mainly overthrusted structures and closed folded structures. large gentle anticlines and synclines are developed from the end of mesozoic to early tertiary, and antithetic sagging structures are developed in mesozoic

    研究發現，本區印支期發育了以褶皺為主、局部伴有小型逆斷層的北西向壓性構造，燕山末期（中生代末期）發育了以逆掩構造和緊閉的褶皺構造為主的近南北向或北北西向壓性構造，中生代末到第三紀早期發育了以寬緩為特徵的大型背斜向斜構造，以及中生界內部的逆牽引構造。
