APPLICATION OF SEISMIC INVERSION TO THE PREDICTION OF BURIED-HILL OIL RESERVOIRS-AN EXAMPLE FROM THE EAST HUANGHUA DEPRESSION

The formation of oil reservoirs in buried hills is very complex.This makes it difficult to confirm oil-play distribution.While studying buried hills in the East Huanghua Depression,the authors suggested a new way to find out oil plays.First,the logging response characteristics of an oil play were used to synthesize the characteristic curves.Then,the comprehensive seismic reservoir characteristic inversion restrained by wells was done to obtain the seismic inversion body of the oil play.At last,by geological ana-lysis,the oil play was recognized directly from the inversion body,and the distribution range of oil pools was determined.This will provide geological bases for the development of oilfields.
