Abstract

Abstract

The current hydrocarbon exploration targets are concealed,scattered,thin,and small.These characteristics put forward higher requirements for the migration imaging technique.Owing to the special acquisition method,the data derived from borehole seismic have the advantages of high resolution,rich wave field information,and less interference.In theory,borehole seismic can be used to realize high-precision imaging of complex reservoirs,such as concealed,scattered,thin and small ones around the well.Well types greatly limit the layout of the seismic sources.In practice,besides vertical wells,there are also many types of wells,such as inclined wells,curved inclined wells,and horizontal wells.For different well types,the seismic sources at the same depth have different positions and the same number of seismic sources have different spatial distributions,leading to significantly different seismic wave propagation paths and further affecting the imaging quality.However,there is no qualitative or quantitative understanding of the effects of well types on migration imaging currently.Using the visco-acoustic inverse time migration imaging method,this study analyzed the effects of well types on migration quality by comparing the seismic migration imaging results of theoretical models under various well types.The numerical results provide the qualitative relationships between well types and borehole seismic migration imaging quality and effective imaging range.The results also provide corresponding theoretical support for the design of a borehole seismic acquisition system.
