METHOD OF BAZHENOV FORMATION DEPOSITS DOUBLE MEDIUM GEOLOGIC AND HYDRODYNAMIC MODELS CONSTRUCTING Russian patent published in 2016 - IPC G06T17/05 G01V9/00 

FIELD: geology; data processing.

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. Summary: core material is studied with extraction of rocks lithological identification and determination of their main properties. Constructing detailed double medium three-dimensional geological model based on stochastic pixel parameters distribution method. Double medium hydrodynamic model is constructed (Kazemi model) with adaptation of formation parameters for deposit development history. Multivariate calculation of deposit development prognostic indices with selection of optimum variant and issue of recommendations for implementation of geotechnical measures are carried out. At that, for construction of geologic model cells types distribution statistical probability is determined, which are assigned with specific values of porosity, permeability, oil saturation, compressibility and connectivity between matrix and cracks by section of each deposit productivity zone. That is ensured by constructing local lithological cuts based on geophysical surveys materials interpretation with detection of law between geophysical parameters and lithologic composition of rocks. For separation of local productivity zones results of wells hydrodynamic research methods, seismic exploration complex data analysis are additionally used.

EFFECT: higher efficiency of searching, design and development of deposits under complex structure of reservoirs due to adequate geological hydrodynamic model.
