ANALYSIS OF THE CORE GLOW INTENSITY AND TEST RESULTSOF PRODUCTIVE ZEOLITE-CONTAINING ROCKS OF SORTYM FORMATION

Abstract

The article deals with the results of studied structure features of reservoirs in productive zeolite-containing rocks. We have established that the content of pelite fraction and carbonate content have impact on the deterioration of reservoir properties, and the development of zeolitization is characteristic for zones of improved reservoir properties.It is shown that the presence of the core glow in the ultraviolet light for zeolite-containing rocks doesn’t guarantee the receipt of the product during testing and will depend on the thickness ratio with different intensity of luminescence. The change in wettability of the rock in the reservoir conditions, an increase in the share of residual oil, and the presence of oil in the dead-end pores are the most likely explanation for the described situation. If the core luminescence is «weak», the product from the reservoir can only be obtained by applying special impact methods.
