Abstract：Aiming at “sandwich”style's complicated surface structure in west of south Boyang depression,we use dynamic character of uphole survey in double well to determine optimum shot hole depth in field operation,which provided a more scientific,straightforward and economic tool for selecting shot hole depth in the field.Meanwhile,the conception of true or false water table is presented combining a large amount of investigating job for surface structure.The analytic method for trial data having lower S/N ratio by using quantitative analysis tools such as time frequency analysis and frequency time analysis and tool using single shot record with pure wave and filtering with predominant frequency band for appreciation of data quality in single shot record provided a use for reference to later analyzing data in similar area.
