"PIETHODE DE TRrZCAGE DE LA BOUE DE FORAGE
PAR DETERINATlON DE LA CONCENTRATION D'UN ION SOLUBLE"."DRILLING MUD TRrZCING PIETHODE
BY DETERINATION OF THE CONCENTRATION OF A SOLUBLE ION ".
Le brevet principal a pour objet une méthode de traçage de la boue de forage au moyen d'un ion traceur qui est l'ion acétate CH3 COO a une concentration comprise entre 1.10-3 et 5,10-2 ion par litre de boue. The main patent relates to a method of tracing drilling mud using a tracer ion which is the acetate ion CH3 COO at a concentration between 1.10-3 and 5.10-2 ion per liter of mud.
On peut déterminer la concentration de l'ion acétate dans le filtrat de l'échantillon recueilli en traitant préalablement le filtrat à doser par de l'acide sulfurique dilué et en distillant l'acide acétique ainsi libéré à une température de l'ordre de 120 à 130 C. The concentration of the acetate ion in the filtrate of the collected sample can be determined by treating the filtrate to be determined beforehand with dilute sulfuric acid and distilling the acetic acid thus released at a temperature of the order of 120 at 130 C.
Au lieu d'acide sulfurique, on peut utiliser un autre acide fort tel que l'acide chlorhvydrique et la distillation de l'acide acétique peut s'effectuer à une température comprise entre 1050C et 1300C. Instead of sulfuric acid, another strong acid can be used such as hydrochloric acid and the distillation of acetic acid can be carried out at a temperature between 1050C and 1300C.
On peut déterminer ensuite l'acidité forte du distillat par l'addition d'une solution d'une base forte telle que la soude jusqu'à l'obtention d'un pH de 4,2 à 4,3, puis l'acidité faible par l'addition d'un volume mesuré de cette solution de base forte jusqu'à l'obtention d'un pli d'environ 8. The strong acidity of the distillate can then be determined by the addition of a solution of a strong base such as sodium hydroxide until a pH of 4.2 to 4.3 is obtained, then the acidity weak by adding a measured volume of this strong base solution until a fold of about 8 is obtained.
On a trouvé, selon la présente addition, que l'on pouvait utiliser une méthode de dosage plus perfectionnée, tenant compte du fait que l'evolution du pH lors du dosage provoque une redissociation d'acides forts en acides faibles, ce qui conduit à effectuer une neutralisation en milieu oxydant. It has been found, according to the present addition, that a more sophisticated assay method could be used, taking into account the fact that the change in pH during the assay causes a redissociation of strong acids into weak acids, which leads to neutralize in an oxidizing medium.
D'autre part, on peut limiter l'incertitude sur la valeur du pH rencontrée dans la neutralisation de l'acidité forte, en utilisant le pK de l'acide acétique reconnu à 4,65 (tampon acétique). Cette valeur n'est pratiquement pas affectée par la température ou le milieu dans lequel se trouve la solution. On the other hand, one can limit the uncertainty on the pH value encountered in the neutralization of strong acidity, by using the pK of recognized acetic acid at 4.65 (acetic buffer). This value is practically unaffected by the temperature or the environment in which the solution is found.
Un objet de la présente addition consiste ainsi en ce qu'apres avoir effectué une oxydation des acides faibles indésirables du distillat par l'iode et avoir neutralisé exactement l'exces d'iode, on ajoute un exces d'iode d'un volume V2 et d'une normalité N1 connus, on neutralise partiellement l'acidité du distillat par un volume mesuré V3 d'une base de normalite N jusqu'à l'obtention d'un pH 4,65.On poursuit la neutralisation de l'acidité jusqu'à l'obtention d'un pH 8, en mesurant le volume total V4 de la base utilisé, on évalue le volume V5 de l'excès final d'iode, notamment au moyen de thiosulfate de même normalité, et on détermine la concentration de l'ion traceur d'après la différence entre la quantité molaire de la base contenue dans le volume (V4 - V3) de base utilisé à la neutralisation de l'acidité entre les pH 4,65 et 8 et la quantité molaire d'iode contenue dans le volume d'iode (V2 - V5) utilisé à la réoxydation d'acides parasites faibles générés par la variation de pli au cours du dosage. An object of the present addition thus consists in that after having carried out an oxidation of the undesirable weak acids of the distillate by iodine and having neutralized exactly the excess of iodine, an excess of iodine of a volume V2 is added. and of a known normality N1, the acidity of the distillate is partially neutralized by a measured volume V3 of a base of normality N until a pH 4.65 is obtained. The acidity is further neutralized until a pH 8 is obtained, by measuring the total volume V4 of the base used, the volume V5 of the final excess of iodine is evaluated, in particular by means of thiosulfate of the same normality, and the concentration of the tracer ion according to the difference between the molar quantity of the base contained in the volume (V4 - V3) of base used for the neutralization of the acidity between pH 4.65 and 8 and the molar quantity d iodine contained in the volume of iodine (V2 - V5) used for the reoxidation of weak parasitic acids generated by the fold variation in during dosing.
La concentration C1 en grammes par litre d'acétate de sodium cristallisé CH3 C00 Na, 3H20 est alors donnée, pour une base monovalente telle que la soude et pour un volume V6 de prise d'essai de filtrat de boue, compte-tenu de la deniineutralisation de l'acide acétique à pli 4,65, par la formule
