【Abstract】 This paper describes the result of a test in a more than 400 m deep well. Practice shows that, with the adoption of some measures, the PS wave of single drillhole layer-testing method can break through the limit of one hundred meters. This technique can therefore be used in more extensive application fields.更多还原
