The technology of picking up the first break of surface microseismic based on constraint

Abstract

In this paper, a constraint based first break acquisition technique for surface monitoring is proposed. This method enables users to automatically pick up the starting point and the ending point of the first arrival position after simply observing the starting point and the ending point of the first arrival position and determining the position. Secondly, because the first break automatic picking method mentioned in this paper will analyze the data characteristics of each channel carefully to find the first break time point in each channel accurately, so that the accuracy of first break picking is significantly improved.
