Description
Die Erfindung betrifft einen Impulsgenerator nach dem Oberbegriff von Anspruch 1.The invention relates to a pulse generator according to the preamble of
Die Erfindung betrifft eine Vorrichtung zur Regenerierung von Brunnen und zur Intensivierung von Förderbohrungen mittels hydraulischer oder pneumatischer Energie-Impulse, welche im zu bearbeitenden Filterbereich des Brunnens oder der Förderbohrung während der Regenerierung kontinuierlich auf und ab bewegt wird und dabei hydraulische oder pneumatische Energie-Impulse erzeugt.The invention relates to a device for regenerating wells and for intensifying production wells by means of hydraulic or pneumatic energy pulses, which is continuously moved up and down in the filter area to be processed of the well or the production well during regeneration and thereby generates hydraulic or pneumatic energy pulses .
In Brunnen sowie in Förderbohrungen lagern sich mit zunehmender Betriebszeit Feststoffe und Inkrustationen ab, welche die Durchlässigkeit des Grundwasserleiters, der Filterkiesschüttung sowie der Filterschlitzung verringern. Ebenso können bereits durch den Bohrprozess bei der Errichtung eines derartigen Bauwerkes Rückstände von z. B. Bohrspülungen die Durchlässigkeit des Grundwasserleiters verringern.With increasing operating time, solids and incrustations are deposited in wells and in production wells, which reduce the permeability of the aquifer, the filter gravel bed and the filter slots. Likewise, residues of z. B. drilling fluids reduce the permeability of the aquifer.
Zur Regenerierung und Behandlung dieser Brunnen und Förderbohrungen sind verschiedene Verfahren bekannt.Various methods are known for the regeneration and treatment of these wells and production wells.
Mechanische Verfahren mittels Bürsten oder durch Eindringen eines Wasserstrahles in den Bereich der Filterrohre sind durch hohen maschinellen Aufwand gekennzeichnet.Mechanical processes using brushes or by penetrating a jet of water into the area of the filter tubes are characterized by high mechanical complexity.
Es sind auch Verfahren zur chemischen Regenerierung von Brunnen und zur Intensivierung von Förderbohrungen bekannt. Diese sind zeitaufwendig und in ihrer Eindringtiefe begrenzt. Auch wirkt die chemische Regenerierung nicht an allen Stellen des Brunnens effektiv.Methods for chemical regeneration of wells and intensification of production wells are also known. These are time-consuming and limited in their depth of penetration. Chemical regeneration is also not effective at all points in the well.
Weiterhin sind auch eine Reihe von hydromechanischen Verfahren bekannt, welche auf anderen Wirkungsweisen beruhen:Furthermore, a number of hydromechanical processes are known which are based on other modes of action:

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung zu entwickeln, die hydraulische oder pneumatische Energie-Impulse freisetzen kann, welche schonend auf das Brunnenmaterial einwirken, und die Vorrichtung effektiv, ökologisch unbedenklich und explosionssicher arbeitet. Impulsstärke und Impulsfolge sollen auf die unterschiedlichen Parameter von Brunnen oder Förderbohrungen einstellbar sein.The invention is therefore based on the object of developing a device that can release hydraulic or pneumatic energy pulses which act gently on the well material, and the device works effectively, ecologically harmless and explosion-proof. The pulse strength and pulse sequence should be adjustable to the different parameters of wells or production wells.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patenanspruches 1 gelöst.The object is achieved according to the invention by the characterizing features of

Sofort nach der Entspannung des Volumens in der Arbeitsdruckkammer
Eine Eingrenzung der Einsatztiefe in Brunnen oder Bohrungen besteht nicht.There is no limitation of the operating depth in wells or boreholes.
Durch eine an der Vorrichtung zusätzlich zu befestigende integrierte Zentrierung kann die Vorrichtung jedem Brunnen- oder Förderbohrungsdurchmesser vor dem Einsatz so angepasst werden, dass sie sich definiert zentrisch im Brunnen oder der Förderbohrung befindet und somit eine optimale und gleichmäßige Ausbreitung der Energieimpulse ebenso garantiert ist wie eine Beschädigung der Brunnen- oder Förderbohrungswand verhindert wird.Thanks to an integrated centering that is additionally to be attached to the device, the device can be adapted to each well or production well diameter before use so that it is centrally located in the well or the production well and thus an optimal and even distribution of the energy impulses is guaranteed as well as a Damage to the well or production well wall is prevented.
Da auch bei diesem Impulsgenerator keinerlei elektrische Leitungen mit in den Brunnen oder in die Förderbohrung eingebracht werden, ist dieser auch ohne zusätzliche Schutzmaßnahmen in explosionsgefährdeten Anwendungsbereichen einsetzbar.Since no electrical lines are introduced into the well or into the production well with this pulse generator either, it can also be used in potentially explosive areas without additional protective measures.
