Abstract

L'INVENTION CONCERNE UN PROCEDE DE PREPARATION D'UNE SOLUTION INFLUENCANT LA MOBILITE DANS LA RECUPERATION DE PETROLE, AYANT UNE EXALTATION D'ACTIVITE DE PLUS DE 15 ET UN RAPPORT DE FILTRATION INFERIEUR A 3 A TRAVERS UN FILTRE "MILLIPORE" DONT LES PORES ONT UN DIAMETRE DE 1,2MICROMETRE. LE PROCEDE CONSISTE A CHAUFFER UNE SOLUTION AQUEUSE DE BIOPOLYMERE DE XANTHOMONAS A UNE CONCENTRATION EQUIVALENTE EN XANTHANE DE0,05 A 2,0 ET A UNE TENEUR EN SELS DE MOINS DE 0,2 PENDANT UNE PERIODE D'ENVIRON2 A 60MINUTES A UNE TEMPERATURE D'ENVIRON60 A 98C, ET, LORSQUE LA CONCENTRATION EQUIVALENTE EN XANTHANE DEPASSE 3000PARTIES PAR MILLION, A DILUER LA SOLUTION A UNE CONCENTRATION EQUIVALENTE EN XANTHANE D'ENVIRON100 A 3000PARTIES PAR MILLION. APPLICATION AU DEPLACEMENT DU PETROLE DE GISEMENTS PARTIELLEMENT EPUISES.THE INVENTION CONCERNS A PROCESS FOR PREPARING A SOLUTION INFLUENCING MOBILITY IN OIL RECOVERY, HAVING AN ACTIVITY EXTENSION OF MORE THAN 15 AND A FILTRATION RATIO LESS THAN 3 THROUGH A "MILLIPORE" FILTER WHOSE PORES HAVE A DIAMETER OF 1.2MICROMETER. THE PROCESS CONSISTS OF HEATING AN AQUEOUS SOLUTION OF XANTHOMONAS BIOPOLYMER TO AN EQUIVALENT XANTHAN CONCENTRATION OF 0.05 TO 2.0 AND TO A SALT CONTENT OF LESS THAN 0.2 FOR A PERIOD OF ABOUT 2 TO 60 MINUTES AT A TEMPERATURE OF. APPROXIMATELY 60 TO 98C, AND WHEN THE EQUIVALENT XANTHAN CONCENTRATION EXCEEDS 3000 PARTS PER MILLION, DILUTE THE SOLUTION TO AN EQUIVALENT XANTHAN CONCENTRATION OF APPROXIMATELY 100 TO 3000 PARTS PER MILLION. APPLICATION TO THE DISPLACEMENT OF OIL FROM PARTIALLY EXHAUSTED DEPOSITS.
