GRINDING OF THE SURFACE OF RECONSTITUTED HARD-TO-PROCESS POWDER MATERIALS

Abstract

Geological and hydrodynamic three-dimensional digital models (geological and technological models) are currently widely used to predict the degree of displacement of oil and gas from productive formations, oil recovery or oil recovery coefficient.  Based on these models, the assessment of geological and recoverable hydrocarbon reserves is carried out, and the optimal strategy for additional exploration and development of productive formations is justified. The creation and application of such permanent geological and technological models is one of the main directions for improving the quality of design, management and control of the development of oil and gas and oil fields. The main indicators of the macro-heterogeneity of the formation are sandiness, fragmentation, and discontinuity of the formation. The discontinuity of the formation can be caused by both the wedging of the formation and its replacement by impermeable rocks.  A consequence of the discontinuity of the formation is the presence of many sand bodies (lenses) with different geometric dimensions both laterally and horizontally, within which fluid movement is possible. The influence of the macro-heterogeneity of the formation is of great 
importance on the coefficient of impact coverage of the formation. This should be taken into account when designing the development, both at the initial stage and subsequent stages.  The paper presents the possibilities of modeling as a tool for substantiating technical and 
technological solutions in the process of oil production and taking into account lithological macro-heterogeneity in the construction of digital geological models of oil and gas fields for the tasks of calculating geological and recoverable hydrocarbon reserves, predicting reservoir 
productivity and monitoring their development.
