Abstract:

In recent year, with the expanding petroleum exploration, lithologic hydrocarbon reservoir has become the key for the further oil & gas exploration. Because of its inherent characteristics, such as low resistivity, little difference from water layer electric property, and low oil saturation etc., there are many difficulties in the reservoir prediction and the identification of the water/oil bed. Based on the analysis of geologic features of lowresistivity hydrocarbon reservoir and formation mechanism, referred to the origin, the geological logging and well logging data of low- resistivity hydrocarbon reservoir in northern Taibei, Tuha Basin were studied. A set of comprehensive methods that could be used to identify low - resistivity reservoir was put forward, which is significant for the future reservoir interpretation and evaluation.

Key words: deep oil-gas, topographic interference wave suppression, oil- gas prediction, cross- hole seismic
