PROCESS MONITORING EXPLOITATION OF OIL FIELDS Russian patent published in 1999 - IPC

FIELD: oil industry. SUBSTANCE: process includes conducting of geophysical and geological examinations of wells and laboratory studies of properties of pool fluids and porous media, interpretation of materials of geophysical and geological examinations, building of detail volumetric geological and hydrodynamic model of lamination-inhomogeneous pool by dismembering and correlation of sections by data of geophysical and geological examinations, determination of volumes of collected oil in production wells and volumes of pumpings in injection wells and issue of recommendations to carry out geological and technical measures. Complex of logging investigations of wells is performed additionally and local geologic-statistic sections are plotted by complex of logging curves. Adoptive approach consisting in storage of knowledge on peculiarities of geological structure of pool by way of successive transfer from exposure of global laws of change of geological and geophysical characteristics to bringing to light and registration of local peculiarities of structure is used for dismembering and correlation of sections. This base is employed to construct detailed volumetric geological and hydrodynamic model of lamination-inhomogeneous pool and hydrodynamic linkage of correlated semi-pools of adjacent wells is additionally corroborated by comparison of volumes and dynamics of pumping and intervals of perforation of injection wells and dynamics of extraction of oil and water, intervals of perforation of production wells and/or by conducting of additional studies by geophysical methods. EFFECT: enhanced authenticity and efficiency of process under conditions of complex structure of collectors. 2 cl, 6 dwg
