The application of the permeability obtaining with stoneley-wave inversion in those complex lithology reservoirs with lower porosity and permeability shows that the permeability from stoneley-wave is a good reference to divide into zone for those reservoirs with relatively good wellbore conditions, big sediment thickness and good homogeneousness. This enlarges the application scope of acoustic logging.

斯通利波渗透率在低孔、低渗透性复杂岩性储层的应用结果表明，对于井眼条件相对较好、储层发育厚度大且均质的该类储层，可参考斯通利波渗透率进行储层的有效性划分，从而拓宽了声波测井的应用范围。

In order to draw a circle around coarse sand concentrated coming area in sediment-laden and coarse sand area of the middle Yellow River,the paper makes macro analysis on the factors of geological structure,lithology of stratum,category of landforms and hydrometeorology of the sediment-laden and coarse sand area in the middle Yellow River and regional difference related with coarse sand production.
