METHOD OF RESEARCH OF GAS MEDIUM DYNAMIC PROCESSES OF UNDERGROUND GAS STORAGE Russian patent published in 2001 - IPC

FIELD: oil producing industry; applicable in research of fluid dynamics of underground gas storages. SUBSTANCE: method includes injection of indicators in gas carrier through different central injection wells into formation under maximum pressure. Injected into each said well is indicator of one color in the form of gas-filled microgranules with 0.5-0.6 mcm degree of dispersion. Microgranules consist of mixture of polycondensation resin and organic luminescent substance. Amount of indicator is determined by formula. During reduction of pressure down to minimum weighted average on area value, gas samples are taken from producing wells. Subject to determination at variations in time are concentration of indicators of each color and volume velocity of gas of all producing wells. Total amount of indicator of each color admitted to each producing well and fraction of migrating gas are determined by offered formulas. Maps are constructed and directions of intraformation and interformation crossflows are detected by value of migrating gas fractions and zones with different gas dynamic characteristics are outlines. EFFECT: higher reliability of research due to presentation of volume pattern of gas migration with use of indicators of several colors. 2 cl, 3 dwg, 2 tbl
