Abstract

Inventia se refera la un procedeu de recuperare a titeiului cu densitate mare sau medie dintr-un mediu poros, prin injectia continua sau intermitenta în mediul respectiv, prin cel putin o gaura forata aflata în comunicatie cu aceasta a aburului sau apei calde si deplasarea agentului folosit prin mediul poros împreuna cu titeiul, spre cel putin o alta gaura forata, prin care are loc extractia la suprafata fluidelor. Procedeul, conform inventiei, consta în adaugarea în agentul termic, constituit din apa fierbinte, abur sau apa fierbinte si abur, a unei substante care la temperatura de scazamînt este putin solubila sau sublimeaza în apa si titei, dar este solubila sau sublimeaza în agentul termic, avand punctul de topire sau sublimare mai mare decat temperatura de zacamant, astfel ca dupa injectia agentului termic în zacamant, astfel si deplasarea acestuia în zonele frontului de temperatura, în care are loc o scadere a temperaturii, se produce o resucere a permeabilitatii prin solidificarea substantei respective, dupa care, ca urmare a aportului de caldura adus de catre agentul termic injectat ulterior, are loc o deblocare a mediului poros respectiv.
