Abstract:Some views on how to achieve efficient hydrocarbon exploration in West China are put forward in the article. Hydrocarbon exploration in West China is very difficult. To have efficient exploration,we must follow scientific exploration procedure,make comprehensive geological research,put into more expenditures and new techniques,and pay more attention to exploration efficiency. Particularly, geophysical exploration must go ahead of the rest.Geophysical exploration serves as forerunner,which is embodied not only in exploration deployment. To achieve this,we must ameliorate our thought and develop some key new techniques that will greatly improve the geophysical exploration efficiency in West China. With the development of these new key techniques,both good exploration situation and obvious technical advance in geophysical exploration will come naturally.There are tough surface condition and complicated subsurface geological structure in West China;therefore,static correction,low S/N ratio and migration are three key problem; that influence the efficiency of geophysical exploration. Some definite technical conclusions have been drawn for the two former problems;the third problem involves both velocity field research and prestack migration application. According to the requirements of processing and interpretation of seismic data in mountainous district,I analyse the technical problems to determine the strategy of developing these key techniques.
