| description | The relevance of the study is determined by the considered possibility, in the absence of a core, to identify missed productive deposits in sandy intervals using materials from both the old and the new well logging fund. Modern requirements for the creation and development of the mineral resource base of the Russian Federation at the highest level presuppose the introduction of a large number of fundamentally new deposits and deposits, the profitability of which is established by the level of knowledge. In many cases, it is simply necessary to reduce the time frame and capital costs for exploration work due to the application and additional exploration of data from the past studied fields. The area of the Tambey field is quite promising in light of the active development of the Yamal oil and gas fields. The aim of the research is the illustration of the use of such parameters as statistical intensities of secondary pelitization and carbonatization as indicators of oil and gas saturation of sandy reservoirs in various areas of the Tambey field. Objects: cretaceous sandy deposits of the oil and gas field of the Tambey area of the Yamal Peninsula. Results. The paper demonsrtrates the petrological and geochemical indicators of oil and gas content and their determination based on logging data. Comparison of the results of statistical interpretation of logging data with the results of petrographic core study is illustrated. The work uses an innovative technology of statistical interpretation of logging materials for identifying the intensities of secondary geochemical processes in indication of oil and gas reservoirs. It was confirmed that in the North-Tambey area, with 80 % probability, the indicator of the formation gas saturation is the intensity of secondary carbonatization, provided that its critical value is exceeded by 0,22 conventional units, and in the West-Tambey area, the indicator of the oil and gas saturation of reservoirs is the intensity of secondary pelitization, provided that their values are exceeded up to 0,084 conventional units. |
