摘　　要：阐述了西西伯利亚尼欧克姆组的沉积结构；证实了尼欧克姆组的楔形结构。研究结果认为，楔形体是在崩塌沉积过程中的水进水退沉积旋回中形成的一种岩体。这些楔形体可分为两种砂岩－粉砂岩的储集岩体， 它们分别与大陆架沉积和末梢沉积有关，在每一种储集体中都广泛发育着不同类型的圈闭。应当把楔状体当作特殊的地层和含油气层单元来研究。This paper stated the sedimentary structure of Niochem formation in west Siberia with a wedge-shape structure． Study results suggested the wedge shape rock body is formed in collapse sediment depositional process during marine ingression and regression cycles procedure． These wedge-shape rock bodies could be divided into two kinds of sandstone-siltstone reservoir rock bodies relating to continental shelf deposition and ending deposition respectively． Various kinds of trapments are widely developed in each kind reservoir bodies． It is considered that the wedge-shape rock body should be regarded as special formation and special oil-gas bearing unit in geologic studies．
