DEVICE OF PHYSICAL-CHEMICAL PROCESSING OF WELL Russian patent published in 2016 - IPC E21B43/00 E21B36/00 E21B43/25 

FIELD: oil industry.

SUBSTANCE: invention relates to oil industry, namely to a physical-chemical well processing. Proposed device consists of heater-reactor housing, which is connected with ejector by means of connecting element. Ejector is equipped with input to supply process substances and at least one input of liquid reagent with a check valve. Inside the heater -reactor housing there is reaction zone filled with heat- and chemically resistant filler. Along the whole length of the reactor zone there are composite electric heaters and temperature sensors, wires of which are isolated in the protective cover. Wires are introduced into the housing of heater-reactor together with power cables of electric heating elements by sealed lead-ins. Electric heating elements are interconnected in train orientation and are fixed on input and output of reactor zone by centering devices. At the output of reactor zone there is a filter to prevent loss of fine particles and open fire from reactor zone, and plug equipped with check valve. For higher sealing and more uniform distribution of filler within reactor zone in the housing of heater-reactor at the inlet of reactor zone between connecting element and centering device there is a pressing mechanism installed.

EFFECT: invention allows controlling and maintaining temperature at any point of the reactor, obtaining fine-dispersed mixture of reagents fed into the device, increases efficiency of in-core processes.
