Tutorial a proposed polarity standard for multicomponent seismic data

摘要

This paper proposes a multicomponent acquisition and preprocessing polarity standard that will apply gen- erally to the three Cartesian geophone components and the hydrophone or microphone components of a 2-D or 3-D multicomponent survey on land, at the sea bot- tom, acquired as a vertical seismic profile, vertical-cable, or marine streamer survey. We use a four-component ocean-bottom data set for purposes of illustration and example. A primary objective is a consistent system of polarity specifications to facilitate consistent horizon correlation among multicomponent data sets and enable determination of correct reflectivity polarity.
