Abstract: After developing and growing for several decades, PetroChina holds more than 150 crews covering the geophysical technique service, their annual acquisition capacity reaches 2D 100 thousand km, 3D near 40 thousand sq.km ,ranked the first in the world, and meanwhile posses a staff of seismic data processing and interpretation with perfect skill. Up to now, the company has formed a series of dominant geophysical techniques including 6 acquisition, 6 data processing and 11 data interpretation,and have been developing 3 acquisition-processing techniques focusing on complicated region, and actively tracking 3 preceding geophysical techniques. However, the objects that oil/gas exploration of PetroChina are faced with might be more and more complicated, and the quality request for seismic data will be needed to raise gradually with the exploration degree upgrading, through developing continuously the seismic exploration technique and generating the series matching technique with special features , tackling key bottleneck technique and tracking the development of forward technique ,PetroChina will be boosted to realize its maximum benefits in oil/gas exploration and development

Key words: seismic acquisition technique, seismic processing technique, seismic interpretation technique, status, developing tendency, PetroChina
