Abstract:

Multi well log reservoir characterization technique is a new technique which combines reservoir geology with well log.The technique is characterized by plenty of information and complete characterization of the reservoir's 3-D geological property.On the basis of the reservoir interpretation model which was established by log data standardization of different well types and core analysis in GB8-X2 block reservoir of Bamianhe Oilfield,the plane variation characters of lithology and petrophysics were studied and high resolution structural map was made,and then low-resistivity pays was identified.According to these,the dynamic prediction of reservoir flow was made by subdividing reservoir units and resedual oil enrichment could be found. This technique is used to search for residual oil enrichment zones,the result is successful.The totalized newly proved reserves are 248?10⁴t and available reserves are 51?10⁴t.
