Abstract:Non-seismic exploration techniques will greatly interest explorationists because hydrocarbon exploration becomes difficult and difficult,and because the requirement of exploration effect gets high and high. The author analyses some major developments of non-seismic techniques since 1990,their important role in hydrocarbon exploration,and their future development tendency. It is pointed out that with further technical development,non-seismic techniques will work in whole process of hydrocarbon exploration,therefore they are the necessary cooperators of seismic technique,and also the necessary ordinary techniques for efficient hydrocarbon exploration.
