Abstract

Procedeul de exploatare a titeiului dintr-un strat petrolifer, conform inventiei, se caracterizeaza prin aceea ca în strat este injectat prin gaura forata, dupa injectia unui dop frontal, un dop activ constituit dintr-o emulsie formata din 20...95% în greutate apa de injectie sau apa de zacamînt care contine 0...5% în greutate ioni bivalenti, 5...80% în greutate titei brut cu o greutate specifica la 16 degree C mai mare de 0,9042, 0,1...15,0% în greutate emulgator constînd din compusi oxietilati carboximetilati cu formula generala: (vezi formula) în care R este un rest alifatic linear sau ramificat cu 6...20 atomi de carbon sau un rest alchil aromatic, eventual substituit cu 3...14 atomi de carbon în grupa alchil, n are o valoare cuprinsa între 1 si 30 si M este un ion de metal alcalin sau alcalino-pamîntos, sau de amoniu, raportul de amestec dintre substanta activa de interfata anionica si cea neionica fiind de 100:0 pîna la 40:60 si de preferinta de 100:10 pîna la 70:30 si în cazul în care apa de zacamînt are un continut relativ scazut în ioni de metale alcaline pamîntoase se adauga pîna la maxim 5% în greutate saruri de metale alcaline pamîntoase solubile în apa de zacamînt, alese de preferinta dintre CaCl2 si MgCl2, temperatura de inversare a fazelor emulsiei fiind cu 0...10 degree C si de preferinta cu 1...5 degree C deasupra temperaturii de zacamînt.
