ORIENTED, MULTI-COMPONENT, DOWNHOLE SEISMIC DATA PROCESSING METHOD

摘要

The invention relates to a method for seismic positi onner in the space of geological events in the vicinity of the well and calculate their age and their penda direction dip. - It comprises the reception by several operative daring multi-axis seismic receivers in a well and coupled with the formations surrounding the well, the components following th ree seismic waves axis reflected by the discontinuities of the basement in response to waves if smiques emitted into the soil by a seismic source at the surface, the allocation to sismiq data ues received data defining the orientation in space multi-axis seismic sensors s reception, the parallel application to the three components of the received waves t reatment of operators allowing selection among the waves received at each multi-axis sensor, polarized waves including those whose polarization direction is parallel to the direction of propagation, the location in space, with each sensor multi- axes, respective directi ons from these polarized waves and positioning in the e spaced seismic events that generated said waves. - Application to seismic type with surface seismic source, dan s the same well as the receptors or in another well.
