Abstract：Mid interval sand bodies in the third member of Shahejie farmatian in Fanjia area shave camplicated gealagy phenamena,sa that explarers have different apinians an sedimentatian type of the sand badies.We researched into the sand bathes which are characterized by drag and gravity flaw phenamena.We have discavered that the sand units shave special geolagy phenomena(black tearing,black splitting and black migration),and that the sand units retain the characteristics of lithalagy,petraphysics,water flaw and ariginal structure(oblique bedding)of an ariginal delta frant.It is abvious that such a sand unit belongs in a new sedimentatian type,name- 1y slump mass sedimentatian type.According to the seismic reflection characteristics of sand unit in slump mass sedimentatian type,we use the saftwares of structural stratigraphy sequence to canvert a filtered seismic sectian inta a relative wave impedance sectian, in which sand bodies can be known by analysing the reflectian amplitudes relating to sandrack and mudrock.Quite good effect has been received in the interpretatian.
