SYSTEM OF CONTROL OF PROCESS FLUID DISTRIBUTION AMONG WELLS Russian patent published in 2001 - IPC

FIELD: oil-producing industry. SUBSTANCE: system has a cluster pumping plant. Device for injection of process fluid into formation is connected to discharge line of cluster pumping plant and made in the form of hydraulic pressure transducer having hydraulic motor and booster pump kinematically connected thereto. Pump shaft is kinematically connected with a proportioner of chemical reagents and instrumentation unit. Hydraulic motor and pump may be made as volumetric displacement devices, for instance, piston-type ones and as dynamic action devices, for instance, in the form of hydraulic turbines, centrifugal or axial-flow pumps. Inlets of hydraulic motor and booster pump are connected to discharge line of the cluster pumping plant. Provision is made for direction of fluid flow after hydraulic motor to well where injection is to be limited. After the pump, fluid is directed to well which requires forced injection. EFFECT: higher oil recovery from formation. 4 cl, 4 dwg
