METHOD AND DEVICE FOR ADJUSTABLE INJECTION OF FLUID TO LAYERS WITH AUTOMATED MEASURING OF PROCESS PARAMETERS Russian patent published in 2017 - IPC E21B43/14 E21B43/18 

FIELD: oil and gas industry.

SUBSTANCE: invention falls into the area of the maintenance of the reservoir pressure on the multilayer field and can be applied at the dual injection of fluid to one or more layers of one well, as well as in a number of cases it may be applied to control, investigate and cut-off of the injection of fluid to the layers in the deep disposal well. A packaging arrangement, including a socket or a shank, a lower packer, a disconnecter, a device for measuring the parameters of the injected fluid, a pumping distribution device, upper packer, an anchor, a disconnecter and an extension tool are lowered to the well on the flow column - FC. Along the immersible downhole equipment the controlling cable is routed (geophysical and/or fiberglass cable or cable of other type) to measure the parameters of the injected fluid. If necessary to measure the parameters of the injected fluid, the extractible part of the pumping distribution device is extracted and the diameters of the flow beans are modified, or, if necessary to disable the pumping of any layer, an appropriate end plug is installed instead of the flow bean. On the device chassis on the outer lateral face there is a linear bore back in the form of a channel for laying the controlling cable from the device for measuring the parameters of the injected fluid, as well as a flow channel of the diffuser is made in the form of a nonconvergent conical body, developing into a cylinder. A technical result is to improve the effectiveness of the device for measuring the parameters of the injected fluid.

EFFECT: invention provides the possibility by means of one device to implement the adjustable injection of fluid to the layers and using, at least one of the measuring device to perform the measurements of the basic parameters of the fluid injection.
