FLOW REGULATION OF MULTIPHASE FLUID MEDIUM, SUPPLIED FROM WELL Russian patent published in 2010 - IPC E21B43/12 

FIELD: oil-and-gas production.

SUBSTANCE: method provides installation in point lower than forward of flow of shutter, allowing regulated passage opening. They provides flowing of multiphase fluid medium at selected size of passage opening of shutter. It is selected one of parametres of flow of multiphase fluid medium, which is sensitive to changing of gas content ratio and liquid in multiphase fluid medium in point higher than flow. It is selected specified value of flow parametre and it is implemented continuous inspection of mentioned parametre of flow. It is regulated mentioned parametre of flow in the direction of its mentioned value by means of management of size of opening of shutter. Additionally regulation time from detection of an deviation from mentioned value up to management of opening less than period of time required for passing by multiphase medium of 25% distance between mentioned time higher than flow and lower than flow. Furthermore, it is proposed well, passing into underground stratum of field for flow of multiphase fluid medium, directed to surface, outfitted in point lower than forward flow by shutter with regulated opening and regulation system, provided for regulation of multiphase medium.

EFFECT: effectiveness and reliability increase in different situations with minimal requirements to facilities of hardware of regulation process.
