Identification method of low amplitude structure in Matouying bump salience

Through present data comparison,the stratum attitude revealed by drilling data of Matouying bump salience is inconsistent with that of revealed by seismic data in time domain,and there is a big difference between structural features of T0 map in time domain and true structural features of Guantao formation.In view of the problems of Matouying bump salience such as low structure amplitude,thin sandstone layers and complex structure types,through seismic data reprocessing,and corresponding interpretation and analysis with different methods,based on fine velocity analysis,by use of Variable-velocity mapping technology,the research on low amplitude structure of Matouying bump salience has been reconfirmed.The actual drilling results the structural form by variable-velocity mapping is consistent with that of true structural shape.And therefore,the implementation of structural form has provided technical support and accurate reference for exploration and development workof Matouying bump salience in the future.
