Abstract: As petroleum exploration applied to more and more regions, piedmont zone in foreland basin is becoming new areas in searching for the presence of hydrocarbons.Because of the complex surface and subsurface conditions, the field acquisition is difficult, and the data acquired is low in S/N ratio, and the subsurface structures difficult in imaging.According to the questions in geophysical prospecting, we put forward the acquisition parameters on the basis of forward modeling, with small group in terval, high coverage and optimum source-receiver offset as petroleum prospecting for complex structu repositions.Improving the S/N ratio of the record should be applied during data acquisition and processing.All of these advance new strategies for geophysical exploration in mountainous areas later.
