Seismic Technique of Exploring Natural Gas in Loess Plataeu and Interpretation
-
Abstract
Owing to complex ground feature of loess plateau, acquiring seismic data is difficult. The following measures are taken: in area of corrasional gullies, the high resulution technique of curved line is used, in smooth area on top of loess plateau, the nonvertical survey line technique is used, and the condition of receiving signals is intensified. Therefore several difficult problems in data processing are initially resolved. An appropriate method of integreted geophysical interpretation has been gotten, and it is applied to determig traps of storing natural gas in Palaeozoic.
