The Applications of Cluster Analysis of Reservoir Evaluation in Chang 8 Oil Reservoirs of Baibao Oilfield

Reservoir evaluation, which works throughout the oil and gas development, has always focused on exploration and development needs [1-3].There are many influencing factors and data in the evaluation process, thus it’s difficult to select the reasonable evaluation parameters and methods. Selecting the appropriate evaluation parameters and evaluation methods can improve the accuracy of evaluation, reduce the evaluation workload. Regional studies have shown that Delta-front sub-facies is the major sedimentary type of the Chang 8 in Baibao oilfield, widely distributed delta distributary channel and mouth bar sands are good oil and gas reservoirs in the area. In this paper, cluster analysis reservoir evaluation is using to obtain their correct evaluation parameters, in order to provide the basis for further development.
