摘　　要：深水浊积砂体及其体系域以其重要的理论意义和作为油气储集层的经济价值始终是沉积地质学研究的主要领域之一。深水浊积砂体是在深水环境下在重力作用下所形成的一个连续过程的组成部分。这个连续部分可以分为五类:泥石流、颗粒流、流体化沉积物流、浊流和滑塌。由浊流过程形成的深水环境下的浊积砂体,具有海相浊积体和湖相浊积体的特征,与海(湖)平面的下隆低水位有关。The main theory sighificance and commercial value for oil reservoirs of deep water turbidite sandbodies and system are one of main research area of sediment al geology.The deep water turbidite sandbodies is a continuous component part which formed in deep water environment by gravitation.The part can be divided into five types： debris flow, grain flow,fluidify sediment flows,turbidity current and slump.The paper shows deep water turbidite sandbodies which formed by turbidity current and discusses the characteristic and genesis mechanism of deep water turbidite sandbodies.
