Abstract

Abstract

At present,the targets of oil and gas exploration have transformed from simple structural oil and gas reservoirs into deep complex structural oil and gas reservoirs.The small thickness,wide distribution,and hidden occurrence state of the reservoirs pose great challenges to seismic migration imaging technology.Compared with ground seismic,the seismic sources of the borehole seismic are located in wells and close to target layers.Meanwhile,the times that wave field induced by the borehole seismic passes through the low-velocity zone reduce by one.Therefore,the borehole seismic has the advantages of high signal-to-noise ratio (SNR) of data and strong reservoir identification in theory and thus can serve the purpose of the fine imaging of the reservoirs around wells.However,the special observation method makes it difficult to directly apply mature ground seismic imaging technology to the borehole seismic.In addition,due to the weak source energy of the borehole seismic,the formation absorption attenuation effect produces stronger impacts on the borehole seismic than on the ground seismic.Therefore,it is necessary to develop a targeted migration imaging method for borehole seismic.This study applied the visco-acoustic reverse-time migration imaging method to the borehole seismic and discussed the influence of various factors on the migration imaging effect of borehole seismic through model calculation,aiming to provide theoretical and technical support for the practical application of borehole seismic technology.
