| 摘 要： | 岩矿资料表明,鄂尔多斯盆地西部环县地区延长组长6三角洲沉积体系物源来自西部。进一步的地震相研究表明,该三角洲沉积体系在虎洞一带分为两支,一支沿环县-樊家川一线呈东西方向展布,另一支顺洪德方向呈北东向延展,并在耿湾-罗卜塬附近与东北物源体系的安边三角洲交汇。

| Abstract: | Decrease of debris and nonresistance minerals and increase of stable minerals such as quartz and zircon from west to east in the Huanxian region show that sediments of the Chang 6 delta system in this area was from the western regions.Three kinds of seismic facies could be recognized in the Chang 6 beds:the middle or high amplitude value-subparallel-relatively continuous reflection,the foreset reflection and the middle or low amplitude value-parallel reflection,corresponding to the deltaic plain,the deltaic front and the prodelta clay(or interdistributary clay), respectively. Distribution characteristics of seismic facies suggest that the Huanxian Chang 6 delta system could be divided into two branches in the Hudong region:one extends easternwards from Huanxian to Fanjiachuan,another goes to Hongde in NE direction and meets with the Anbian delta in Gengwan-Luobuyuan region.The front parts of the eastern Huanxian delta of Well Huan 4-Huan 41 are the ideal places to explore the lens and pinchout reservoirs. |
