Abstract:
This paper discusses the contents and features of current Zero-offset VSP(ZVSP) techniques for the development stage of oil and gas exploration in aspects of data acquisition, processing and interpretation. The features involve: acquiring high-resolution ZVSP data, correlating not only thick layers, but also thin layers or reservoirs; exploiting multi-waves, using not only upgoing and downgoing waves, but compressional and converted waves simultaneously; extracting dynamic parameters, providing not only scale for time-depth relation and horizon scale for corridor-stack, but scales for amplitude, frequency, Q, wavelet, compressional-shear wave velocity ratio, Poisson ratio and elastic parameters; directly detecting lithologic properties, oil and gas, not only correlating, controlling and constraining horizon inversion, but identifying different types of reservoirs and providing constrains for joint petroliferous property inversion of both borehole and surface seismic data.
