SELF-CONTAINED PORTABLE UNIT FOR STEAM GENERATION AND INJECTION BY MEANS OF INJECTOR WELLHEAD HANGER OF COILED JACKETED CAPILLARY TUBING WITH CLOSED CIRCUIT AND PROCEDURE FOR ITS OPERATION IN OIL WELLS

摘要

A self-contained portable unit for steam generation and injection by means of an injector wellhead hanger of coiled jacketed capillary tubing with a closed circuit and procedure for operation in oil wells comprises a portable, self-contained equipment for injection and dewaxing of heated fluids mounted on a hauler that includes a heat exchanger, a water tank, a heat exchanger, a softener, a centrifugal pum, a lubricant tank, a power engine, an electrical power generator, a control cabin, a fluids softener, a steam boiler, a reservoir tank, a fuel tank, a hose reel and one hose set for two lines of fluid injection and return of that connect to a wellhead hanger/injector for two capillaries making up a closed circuit. This wellhead includes three module and crowned with a lid, two of which are hangers and the rest are injection-type.

1. A self-contained portable unit for steam generation and injection via an injector wellhead hanger of coiled jacketed capillary tubing with a closed circuit for operation in oil wells, comprising:
self-contained equipment for injection and dewaxing of heated fluids, comprising: one hose set for two lines of fluid injection, the lines being connected to a wellhead hanger/injector for two capillaries making up a closed circuit; wherein the wellhead comprises three modules crowned with a lid, two of which are a first and second hanger and at least one is an injection-type, said hanger module having a set of double clamps that support capillary tubing of greater cross section; wherein the injector overlaps the hanger and is fixed, the injector connected to the portable unit for steam generation via a hose, and overlapping the injection-type module, an upper hanger is fixed, which has a capillary of smaller cross section and recovers steam from a well, and leading the fluid to the injector where it is treated thermally, and from the end of the capillary of the upper hanger, it is inserted in the tubing, making a closed circuit.
