Fine Evaluation Criteria and Parameters of Baqukeshang Formation Conglomerate Reservoir in Kelamayi Oilfield

In view of the sedimentary and reservoir features of the Baqukeshang Formation conglomerate reservoir in Kelamayi oilfield, logging, coring, formation testing and other relevant geological data were used to match and extract parameters based on the analytical criteria of gray system theory. The lithology, physical properties and oil-bearing properties of the conglomerate reservoir were studied by using the statistical characteristic value and its accuracy and resolution. Parameters and indexes for fine reservoir evaluation were determined and a model was built. The parameters, criteria and weight coefficient for fine evaluation of this conglomerate reservoir are introduced in this paper through fine evaluation of reservoirs in 117 wells. A reliable geological basis is provided for further exploration and development of the Baqukeshang Formation conglomerate reservoir.
