Definitions
- the present invention relates to a method and a Device for maintaining the performance of new Wells as well as for cleaning and regeneration of existing ones Wells, particularly wells.
- the currently most common type of fountain is the Drilling wells, with vertical and horizontal wells be distinguished.
- the vertical well is there in principle from a pipe string that after sinking one Hole is inserted into the borehole.
- the pipe string has inlet openings at the level of the water-bearing layers or filter pipes for the passage of water.
- the fountain To fine sand of the upcoming soil from the entry openings to keep away, the fountain must be with such a large borehole diameters are made that between Filter tube and borehole a sufficient fill from sieved and washed filter gravel can be.
- a phenomenon feared in well construction is the so-called blocking of well filters, which can lead to a considerable loss of performance in the well in question.
- the cause of the loosening is water level fluctuations in the area of the filter tube as a result of water extraction, which lead to the fact that Fe 2+ ions in the trapped water of the filter are oxidized to Fe 3+ ions by the entrained oxygen-containing soil air, which precipitate out as poorly soluble Fe 3+ hydroxides and as a result of the constant repetition of this process, gradually close the flow paths in the filter gravel and the inlet openings in the filter tube.
- the loosening takes place independently of the filter material and can generally only be avoided by keeping the water level in the well above the upper edge of the filter tube. However, this is hardly possible in practical operation.
- iron bacteria can also cause a loosening be conditional on their metabolic activity Convert divalent iron into trivalent iron. On this also leads to the formation of sparingly soluble Hydroxide.
- WO-A-91/12406 already describes a method for Cleaning and regeneration of wells and in particular to remove incrustations in the form of Blockages and / or sintering known the well pipe and a gravel fill surrounding it be ultrasonically applied to the Loosen incrustations and vacuum with water.
- the present invention is therefore based on the object based on a method and an apparatus for Maintaining the performance of new wells as well as Cleaning and regeneration of existing wells Specify ultrasound or design so that a effective and inexpensive cleaning of the well is guaranteed.
- the object is achieved with a method solved according to the features of claim 1.
- the basic idea of the invention is in that a delimited section of each Well filter and the adjoining one Filter gravel area in the stationary state of the Ultrasound generator applied as long as ultrasound until a measurement is taken in the extracted medium Cleaning effect is proven.
- An advantageous embodiment of the invention provides that in the well in question Packer used to delimit a cleaning area between which a submersible is placed becomes.
- the cleaning process is thus on one defined, enclosed space concentrated, whereby the cleaning performance is increased.
- Another advantageous embodiment is that the removed by the pump, the detached Well water containing particles of a measuring device is supplied in the physical and / or chemical Characteristics measured to determine cleaning success become. This way, in the interest of a quick Total cleaning can be determined when cleaning completed in a given well area and the cleaning process in neighboring areas can continue.
- the device according to the invention essentially consists from a submersible transducer which emits ultrasonic vibrations, a device for positioning the Submersible within the well and one of them detached particle-removing pump.
- the device shown in Figure 1 comprises a Submersible transducer 3 with a supply cable 2 a generator 1 arranged outside the fountain 4 connected is.
- the diving transducer 3 is in the fountain 4 in the arranged at the top of the filter section.
- Above and Packers 5 are arranged below the immersion transducer 3, which one within the water column of the fountain certain working area of the submersible transducer 3 delimit.
- the diving transducer 3 is adjustable with a rope 6 Submersible pump 7 connected in the upper Packer 5 is arranged.
- a pipe leads from the pump 7 8 from the well 4 to a measuring device 9, in the pumped water by means of electrodes 10 and measured organoleptically continuously and on this Way the cleaning success can be determined.
- the pH value, the turbidity and / or other parameters of the pumped out Water can be detected by the concentration of the loosened ocher particles in the water and one Statement about cleaning performance and / or cleaning success allow.
- the fountain filter is basically sonicated horizontal and acts on both the filter tube and also on the filter gravel and floor area behind 11. To remove the loosened ocher particles immediately to remove the cleaning area, the water above the immersion transducer 3 by the pump 7 continuously aspirated.
- the pump 7 is expedient controlled so that the submersible 3 always from Water is surrounded.
- a submersible transducer 3 with several transducers 12 use.
- the one in FIGS. 2 and 3 Immersible transducer 3 shown has a polygonal trained outer jacket 13 and is with a total twenty star-shaped vibrators 12 equipped so that an intensive sound reinforcement of the relevant filter section is achieved.
- the Diving transducer 3 shown has a power output of around 1200 watts.
- the diameter of the plunger 3 is in relation to the well pipe chosen so that the distance to the pipe wall is as low as possible, but still one there is sufficient scope.
- encrusted and / or clogged well filters not only cleaned, but deposits that contribute to loss of performance Lead wells, can also be prevented preventively.
- the invention is not restricted in its implementation to the above embodiment. Much more a number of variants are conceivable, which of the shown solution even with fundamentally different types Make use of the remarks.
