Study of shale reservoirs by the results of temperature studies
At present, thermometry is an effective method of controlling the development of oil fields. However, the theory and the method of research and interpretation, developed at present, refer, to great extent, to terrigenous reservoirs and to traditional methods of fields operation. The reservoirs fields development, characterized by low porosity and super low permeability values, as well as deposits of shale oil, requires a revision of the theory, methods of research and interpretation of well thermometry. The article presents the results of the data interpretation, obtained during field-geophysical studies of production wells with the data of temperature studies of Bazhenov suite of various fields in the Western Siberia. Bazhenov suite temperature data are analyzed and possibilities of a well thermometry when studying shale reservoirs are shown. The conditions of estimation of Bazhenov suite temperature gradients during wells operation and the most favorable depth interval for solving the geothermal problems in the operating wells are determined. A search indicator of the temperature criterion, which can be used to analyze and predict inflows from Bazhenov suite, is determined.
