Integrated prediction based on GIS for sandstone-type uranium deposits in the northwest of Ordos Basin;

A new kind of integrated technique between remote sensing and gamma energy spectra is put forward,which can recognize lithology in the sedimentary basin and has already yielded good application effects in northeastern Ordos basin.

Clay minerals in Taiyuan Formation sandstones, Northeastern Ordos Basin are generally discussed in the paper, based on x-ray diffraction (XRD), Scanning electron microscopy (SEM), energy spectrum analysis, polarizing microscope and other analyses.

Characteristics and genesis of the Upper Paleozoic tight sandstone reservoirs in the northern Ordos basin;

,in the northern Ordos basin,a study is initiated with the aim of understanding the pattern of abnormal pressure distribution,and the genesis and evolution of pressure in the Upper Paleozoic of the basin by combining its characteristics of universal low abnormal pressure,tight reservoirs,simple sturctures,dispersed gas pays,and compa.
