Abstract: Volcanic rock hydrocarbon reservoir,which is same as the sedimentary rock reservoir,has already become an important domain for increasing reserves in China's oilfields.Liaohe oilfield has a long exploration history and a large potentiality of volcanic rock hydrocarbon reservoir.Its volcanic rock hydrocarbon reservoir being as the main reservoir is very complex.In order to make a successful exploration in the volcanic rock hydrocarbon reservoir,the log response of different volcanic rock inHuanxiling of Liaohe oilfield was analyzed,and the different volcanic rocks were determined using log curve of different lithology.The structural fractures of different volcanic rock reservoirs were identified using the methods of electric conductivity logging,acoustic logging,nuclear logging,dip logging.By the use of interpretation of fracture's log,a geological model for describing porosity of fracture was established,and the fracture's dip was determined,and fracture porosity was calculated.

Key words: Liaohe oilfield, volcanic rock hydrocarbon reservoir, structural fracture, log interpretation, fracture porosity
