Abstract
Inventia se refera la un procedeu de recuperare a titeiului dintr-un strat petrolifer aflat în faza secundara sau în cea tertiara de exploatare, care cuprinde injectia, prin cel putin o gaura forata aflata în comunicatie cu stratul, a unui dop de solutie micelara deplasat prin strat de catre un dop de apa cu vîscozitate marita artificiala si injectia de apa conventionala precum si exploatarea fluidelor provenind din strat prin cel putin o alta gaura forata în acest scop. Procedeul, conform inventiei, consta în aceea ca într-un strat productiv, înainte de injectia apei cu vîscozitate marita artificial, este injectata o solutie micelara în a carei compozitie intra în proportie de 8...37% în greutate o componenta anionica reprezinta 8...32% în greutate si, de preferinta, 8...17% în greutate, iar restul este constituit dintr-o componenta tensioactiva neionica în proportie de 1...5% în greutate si, de preferinta, 3...4% în greutate, componenta tensioactiva anionica fiind constituita din amestecuri complexe de sulfonati de petrol cu cation monovalent, ales de preferinta dintre ionii de sodiu si amoniu extrasi din gudroanele acide provenite de la rafinarea uleiurilor minerale si anume a uleiului alb usor de la toate cele zece trepte de rafinare, si de preferinta pe la treptele 3,4,5 si 6 precum si la rafinarea uleiului de transformator, singur în amestec între ei în raport de 1:1, sau în amestec între ei în raport de 1:1 sau în amestec cu sulfpnatii de petrol-avînd o greutate echivalenta medie de 360...460 obtinuti prin sulfonarea unor fractiuni din motorina de cocsare, care contin structuri aromatice mono, di si polinucleare avînd un interval dThe invention relates to a process for the recovery of crude oil from a secondary or tertiary oil layer comprising the injection of at least one drilled hole in communication with the layer of a micelle solution plug displaced by layer by an increased viscosity water stopper and conventional water injection, as well as the exploitation of fluid from the layer through at least one other hole drilled for this purpose. The process according to the invention consists in that, in a productive layer, before the injection of artificially viscous water is injected a micellar solution in which the composition is 8 to 37% by weight an anionic component is 8 ... 32% by weight, and preferably 8 to 17% by weight, and the remainder consisting of a non-ionic surfactant component in a proportion of 1 ... 5% by weight and preferably 3% by weight. .4% by weight, the anionic surfactant component being composed of complex mixtures of monovalent cationic petroleum sulfonates, preferably selected from the sodium and ammonium ions extracted from the acid tar from the refining of the mineral oils, i.e., the light white oil from all the ten refining steps, and preferably the steps 3,4,5 and 6, as well as the refining of the transformer oil alone in a mixture of 1: 1 or 1: 1 mixed with each other or in admixture with s petroleum peaks having an average equivalent weight of 360 ... 460 obtained by sulfonation of fractions of coke diesel, which contain mono, di and polynuclear aromatic structures having a d
