METHOD OF CONTROLLING DEVELOPMENT OF MULTI-FORMATION GAS DEPOSIT Russian patent published in 2024 - IPC E21B47/06 E21B49/00 

FIELD: mining; measurement.

SUBSTANCE: invention relates to exploration of production wells. Method of controlling development of multi-formation gas deposit involves lowering pressure and temperature sensors into annular space of production wells of the deposit and their connection by means of cables to measuring inputs of individual telemetric system for measuring thermobaric parameters along the shaft of tubing strings, which are equipped with wells of the field. Telemetry system is used to continuously measure pressure and temperature in the tubular and annular space. GSM modem is used to transmit the obtained data to a remote control information system. Further, their automated processing, interpretation, three-dimensional geological-hydrodynamic and thermal modelling of the state of wells of the field to determine the gas-saturated thickness of the formation involved in the drainage by the change in pressure and temperature in the reacting wells, to determine the area of distribution of the formation involved in the drainage, reduction of temperature and pressure as a whole for formations and performance of quantitative assessment of degree of involvement of one or another part of deposit in development, as well as determination of optimal mode of well operation in mode of single gas gathering network, determination of hydraulic losses along tubing string of each well and determination of hydrate mode of operation of each well.

EFFECT: higher accuracy of control over development of multi-formation gas deposit.
