Abstract: PetroChina has began focusing on such domains as high-steep structure, carbonate rocks, low permeability, and volcanic rocks, and carried out geophysical research based on the thought of "highlighting key basins, relying on key projects, popularizing mature techniques, tackling bottlenecks, and leading technical development" since 2006. Since the "11th Five-Year Plan" period, PetroChina has developed four key techniques, remarkably improving the quality of seismic data and the accuracy of reservoir prediction and hydrocarbon detection. In addition, PetroChina has obtained a series of important geologic achievements and explored a set of effective management methods by applying the key geophysical techniques mentioned above, which vigorously enables it to get a growth spurt for oil and gas reserves.

Key words: PetroChina, geophysical technique, research projects, exploration for oil and gas
