Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the cleaning of well shafts has mostly been carried out by first performing a visual inspection of the shaft and then determining, for example, the composition of the washing liquid and the duration of the cleaning process.
  • a device for performing this method is known for example from DE-PS 34 45 316.
  • This object is achieved in that the ion concentration of various ions released from the deposits in the washing liquid is measured during the cleaning process, that the concentration of the ions released from the deposits in the washing liquid is suitably reduced depending on the result of these measurements for the further course of the cleaning , and that the duration of the cleaning process is controlled in dependence on the result of these measurements in such a way that the cleaning process is ended when no appreciable increase in the measured ion concentration is detected, although the washing liquid is still capable of absorbing corresponding ions.
  • the ions to be measured are, for example, the cations iron, manganese, calcium and / or aluminum, and the anions, for example sulfate and / or chloride, and also the cations and anions of the washing liquid additives.
  • sum parameter parameters of the washing liquid containing the various dissolved deposits can also be measured and the further cleaning process can also be influenced as a function of these measurements.
  • the master parameters are essentially the pH value, the conductivity and / or the redox voltage of the washing liquid.
  • the measurement can be carried out continuously or discontinuously. By determining the respective ion concentration and in particular its change over time, it can be determined which composition the Deposits and which detergent composition is the cheapest. If, for example, the concentration of an ion type increases only very slowly, although the absorption capacity of the washing liquid for these ions is far from exhausted, this means that these ion-forming deposits are only present to a negligible extent. If, on the other hand, there is no longer an increase in the concentration of an ion type because the absorption capacity of the washing liquid has been exhausted for this purpose, then suitable measures must be taken to ensure that these ions are absorbed further in the washing liquid.
  • the washing liquid is expediently led out of the shaft upwards and then returned to the shaft. This also facilitates the removal of used and fresh washing liquid, since these measures can then also be carried out outside the shaft.
  • the fresh washing liquid can be used up by reducing the ion concentration of the dissolved deposits in the discharged Washer fluid can be obtained.
  • the composition of the fresh washing liquid supplied is preferably determined by the result of the measurement, so that the absorption capacity is increased specifically for ions which are still present to a considerable extent in the deposits.
  • the deposits to be removed must not only be those that gradually accumulate during the operation of the well, but can also be so-called drilling fluid additives that were used in the manufacture of the well and must then be removed, since they impair the performance of the well.
  • the detergent liquid can also contain additives suitable for disinfection.
  • the measurements carried out then also serve in each case to control the disinfection and, if appropriate, by additional measurements to detect biological activities.
  • the total amount of the deposited deposits, divided into the individual types of ions measured can also be determined. This enables conclusions to be drawn about the condition of the well, for example at what intervals cleaning is carried out or whether the well should be replaced.
  • the concentration of the ions can be replaced by the continuous pumping out of the sample by continuous removal of ions from the washing liquid.
  • the figure thus represents only an example to explain the claimed method and in no way limits the application of the method by the representation of the figure.
  • the necessary measurements can be carried out inside or outside the well.

  1. Procédé pour le nettoyage de puits, dans lequel un liquide de lavage, composé de l'eau souterraine avec des additifs appropriés, est refoulé à partir du tuyaufiltre du puits dans les couches de gravier adjacentes à la paroi du tuyau-filtre et de nouveau aspiré, les dépôts réducteurs de débit à éliminer étant solubles par et dans les additifs et étant dissous par le liquide de lavage et recueillis dans celui-ci à l'état dissous, caractérisé en ce que, pendant l'opération de nettoyage, la concentration ionique de divers ions, libérés à partir des dépôts, est mesurée dans le liquide de lavage, en ce que la concentration des ions venant des dépôts dans le liquide de lavage est réduite de manière appropriée en fonction du résultat de ces mesures pour la suite de l'opération de nettoyage, et en ce que la durée de l'opération de nettoyage est réglée en fonction du résultat de ces mesures de telle manière que l'opération de nettoyage soit arrêtée lorsque aucune augmentation notable de la concentration ionique mesurée ne peut plus être constatée, bien que le liquide de lavage soit encore capable d'absorber des ions correspondants.
  2. Procédé selon la revendication 1, caractérisé en ce qu'en outre, des grandeurs directrices de paramètres sommes des divers dépôts dissous et du liquide de lavage sont en outre mesurées et en ce que la suite de l'opération de nettoyage est commandée en fonction de ces mesures.
