Abstract

Inventia se refera la un încalzitor electric subteran destinat încalzirii unui flux de gaze sub presiune, injectat în strat în vederea maririi factorului final de recuperare a titeiului. încalzitorul poate functiona la o gama variata de temperaturi si debite, avînd posibilitatea unor reglari continue, automate a acestor parametri. Are aplicabilitate în industria extractiva a petrolului. încalzitorul este constituit dintr-un element rezistiv, montat izolat fata de un cilindru de protectie si fata de un tronson de tubing. Curgerea fluidului are loc în spatiu spiralat, de sectiune rezistiv.The invention relates to an underground electrical heater designed to heat a pressurized gas stream injected into the bed in order to increase the final oil recovery factor. the heater can operate at a wide range of temperatures and flows, with the possibility of continuous, automatic adjustment of these parameters. It is applicable in the oil extraction industry. the heater is constituted by a resistive element mounted in isolation from a protective cylinder and facing a tubing section. Fluid flow occurs in spiral, resistive section space.
