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。The main characters of the thermal fluid activity are recognized as follow : many types and stages of veins are widely developed ; vitrinite reflectivity of different areas varies apparently with the depth ; there was a high temperature field during the formation of the thermal fluid, meanwhile, the volcaniclastic rocks were modificated by the thermal fluid activity, for example, sericitization of plagioclase, chloritization of volcanic detritus in andesitic detris tuff ; in the tufaceous mud, the thermal fluid activity accelerates " maturating " of the organic carbon by heating ; and the trace elements show an anomaly in the wall rocks
同時，受熱流體活動的影響，熱流體對火山碎屑巖具有一定改造作用，如在安山質巖屑凝灰巖中，斜長石絹雲母化、火山巖巖屑綠泥石化明顯；在凝灰質泥巖中，熱流體對圍巖中有機碳具有明顯的「催熟」加熱作用，微量元素則出現異常現象。Planation surface is a wide - ranging and undulating surface formed by planation in a long and relative stable period or in a decreacing - development period. it is near the base level and there always exists some deposits such as crust of weathering above it. planation surface is often uplifted or buried by the later tectonic activities
夷平面是在長期的地殼相對穩定時期或地殼下降發展階段，由廣泛的夷平作用以截斷面形式橫切所有先成的地層和構造的接近侵蝕基準面的平緩的地表形態，其上常有風化殼等碎屑堆積，常遭到後期的抬升切割或埋藏，分佈於地球的各緯度帶。These landslides go with fluidization peculiarity different degree in course of their motion, and their speed and distance increase several times because of the fiuidization, thereby the disaster area greatly broaden. on the base of above, the paper studies systematically the fluidization of large high - speed rockslides in all its aspects : analyzed the aerodynamic effect in the short - range on the base of the wind turmel experiment, studied the effect of falling into pieces when landslides collides mountain ; studied the accelerating effect through high - speed collide experiment of landslides model ; and the paper reappear the overall process including set - out, collide in the short range, debris flow in the long - range of touzhai large landslide via distinct element method ( dem ), studied the flow law and equation of different type of debris flow resulted from large landslide. as a sample to apply, the paper analyzed fluidization mechanism of touzhai landslide
基於這一點，本文對大型高速巖質滑坡的流體化現象進行了全面而系統的研究：通過風洞模型實驗，研究了大型高速滑坡凌空飛行階段的空氣動力學效應，研究了飛行中滑坡巖體在與途中不動山體發塵碰撞時的解體破碎效應，通過滑坡巖體高速碰撞模型實驗研究了滑坡巖體解體破碎後部分巖體的加速運動效應，並應用離散單元法再現了雲南頭寨溝大型滑坡啟動高速、近程碰撞、遠程碎屑流運動的全過程，研究了巖體解體破碎后形成不同類型碎屑流的運動規律及運動方程，並對頭寨滑坡流體化運動機理進行了實例分析，取得了以下主要結論和成果： （ 1 ）對于大型高速滑坡，大多在啟程活動階段已獲得了高速，這使得這類滑坡在其離開剪出口之後以凌空飛行的形式向前運動，在其飛行過程中，滑坡巖體與空氣強烈作用，並產生空氣動力學效應，滑坡巖體在因碰撞而產生的解體破碎效應及部分巖體的加速運動效應的作用下，在遠程活動階段，以高速碎屑流的形式向前運動。This is the direct reason of bad reservoir property of sandstone, especially lower permeability. the influence and control factors of reservoirs include : deposition, diagenesis and tectogenesis. the deposition is the basic factor, it control the shape and distribution of sand body, and influence the type and the intensity of the diagenesis ; the diagenesis is the key factor, it control the process of pore evolvement, so the diagenesis control the sandstone ' s storage space and reservoir quality directly ; the fracture of the tectogenesis formation could improve the porosity and permeability of sandstone
其中沉積作用是基礎，控制了儲集砂體的形態特徵和分佈范圍，同時由於不同沉積類型砂體在碎屑成分組成、泥質含量、顆粒粒度、砂體厚度、砂體內部的非均質性、孔隙介質的物理化學性質等方面不盡相同，從而也影響著砂巖所經歷的成巖作用路徑、類型和強度，因此沉積作用是控制儲層發育的主導因素；成巖作用是關鍵，直接決定了砂巖的孔隙演化過程，從而決定了儲層內部儲集空間特徵和儲集性能；而構造作用形成的裂縫對改善砂巖的儲滲性能具有一定作用。分享友人
