Abstract:

It is found that argillaceous sediments are steadily traceable in sedimentation mass. They are characterized by similar patterns of well logging curves and they correspond to the boundaries of identical stratigraphically oil and gas complexes. In the paper on the example of Yaun-Lorsk and Lyantor deposits of the Surgut crest the possibilities and advantages of multidimensional statistical correlation method of oil and gas reservoirs and mass are shown. With the use of the program Statistica producing depths AS9-AC10 on the deposits under investigation are calculated. The close correlation relationship between the depths of fine-dispersed clays of Alymskaya group and producing depth, which was taken into account in the development of geological models, is presented.
