Study on identifiable standard of the deep oil-gas layer in Qiaodubai region

Oil-gas exploration in Dongpu Sag has entered into middle-late period, shallow oil-gas has been basically proved and exploration direction transfers to the deep layer. But because of complex geological conditions, depth of the reservoir, low-porosity and low-permeability, oil-gas exploration is rather difficult, especially in tems of deep oil-gas identification, information quality, it's more difficult to identify the deeper oil-gas layer and constrain the deep oil-gas exploration process. This article takes Qiaodubai region as a model, the traditional "four property" method and standard identification integrated with gas measuring parameters are used to identify the deeper oil-gas, and achieve good results.
