Method of Determining the Parameters of Reserviors of Gas Bearing Volcanic Rocks

The lithology of deep wells in eastern Daqing oil field and complex,so calculating reservoir parameters and recognizing fluid are very difficult.The well log data are processed and interpreted in this paper according to volcanic reservoir interpretation model which is established under the law of lithology grouping.The accuracy and coincidence rate of log interpretation are improved by jointly using the analysis results of imaging logging,lithologic classification and multi-well comparison,etc.The computed porosity,saturation,permeability and other parameters provide the basic parameters for submitting reserve of the area.
