METHOD OF INTEGRATING INITIAL DATA TO UPDATE FILTRATION STRUCTURE OF NON-UNIFORM CARBONATE RESERVOIRS Russian patent published in 2018 - IPC E21B49/00 G01V11/00 G06G7/48 G06F19/00 

FIELD: geology.

SUBSTANCE: invention relates to geological and hydrodynamic simulation and can be used when solving tasks of searching, reconnaissance and design of oil deposits development under collectors complex structure. Proposed method includes determination of the relationship between the seismic attributes and the formation's filtration parameters obtained from the results of the integration of high-performance dynamic well tests, identification of sources of watering wells on the basis of a comparison of the results of complex field and seismic studies, analysis and consideration of the features of fluid filtration in a fractured reservoir on the example of the Lower Permian deposits of the Varandey field, conducting of hydrodynamic calculations on the basis of a detailed geological and filtration model to assess the quality of the created fracture model in the reservoir in terms of the degree of convergence of the calculated and actual performance of wells and the reservoir as a whole, and comparative evaluation of the created and existing filtration models, as well as comparison of the projected production rates of newly drilled wells with their actual values.

EFFECT: technical result of the claimed invention consists in minimizing the occurrence of possible errors in the description of the filtration parameters of the formations, complicated by the developed system of fractures, developing an approach to assessing the activity and nature of manifestation of the water-head horizon, improving the quality of convergence of the obtained development parameters under hydrodynamic modeling and the actual data, as well as optimizing the curves of relative phase permeabilities in the conditions of fractured reservoirs.
