METHOD OF UPDATE OF THE GEOLOGICAL-GAS FLUE MODEL OF THE GAS DEPOSIT ACCORDING TO THE DATA OF OPERATION Russian patent published in 2018 - IPC E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the production of natural gas and, in particular, to the operational control over the development of gas and gas condensate fields in the Far North. By the method increase the reliability of the results of hydrodynamic modeling and its efficiency due to the specification of the parameters of the geological model according to the operational control data and registration of basic parameters of reservoir operation in the regime of non-stationary filtration. For this purpose, it is planned to stop fishing for a given period and subsequently start it in operation. Immediately after the commissioning of the fishery, the wells are tested in a hydroprocessing mode to obtain additional information characterizing the functioning of the deposit being developed. All the data obtained and, in particular, formation pressure, wellhead pressure, temperature, gas flow rate or gas-condensate mixture for each well or bush of wells are used. Make appropriate changes in the three-dimensional geological and hydrodynamic reservoir models. Invention makes it possible to eliminate uncertainty in determining the direction of flow of formation fluids and the effect of wells on each other during their operation in a single system of gas gathering.

EFFECT: increase in the efficiency of development of gas and gas condensate fields by ensuring the maximum level of gas and condensate recovery.
