What if silted well or its water gone?

IN last article about chrede repairs its vibration pumps that "eat" sand, I reported that once again went to the water with a high content of clay and sand.

The bottom has risen again. About a meter, and the situation is rolled back. The pump does not have time to pump the slurry. Tired of these "dancing with a tambourine." Decided to ask other drillers on by washing wells. Cost - 6 thousand. rub. Car comes with the water tank and a powerful pump - is thrust hose with a "needle" (a narrow tube with a diagonal cut) and the water pressure on the surface washes away all the sand.

Likewise free stuck in the sand pumps.

It looks like this:

His video of the process did not take off.

Revised set of similar rolls, including with explanations. Realized that this must be done, because pump from the wellbore 5m sand vibrating pump almost unreal

Came Zil-131 with the container and pump. Pumped well for 15 minutes. Hydrant reached the bottom. Measured the level of the bottom water hose.

At first glance it did not work out so much sand. But given the fact that it flowed over the area - the sand is actually a lot.

Otkapal headboard drill pipe obstuchal its sledgehammer gravel that would fell as low as possible. It was heard as it strikes after sprinkled. Obstukival before ending obsypaniya sounds. I fill up a bucket of pebbles around the annulus.

Perhaps it will make tapping more dense around the filter slots of the casing and so much sand when pumping more will not come out.

After immersion pump sand went out. But not as much as the washing up. The water after 5 minutes of settling.

In the search for information in youtube, I stumbled upon manual cleaning methods silted wells (video presents two well recovery method):

Photo left - a vibrating pump to the lower wall of the pump changing cover with the upper wall and screwed into the outlet long bolt. Water outlet thus continue through the upper cover.

Photo on the right - to the pump housing to the lower fence bolted bracket. In both cases a bolt bracket and during operation of the pump (as it vibrates) will lift the slurry of sand and sludge, and a pump to pump the slurry with water. This method is suitable for small sediment accumulation.

The pump can be clogged with large stones - they may get stuck into the inlet.

Well, if the water is gone, or have a lot of sand (as in my case), it is only the pressure of the washing water.
