Abstract

The invention relates to the technical field of well washing equipment, and provides underground water well washing sampling equipment which comprises a washing pipe and a sewage discharging device which are arranged on a lifting platform, a water supply device connected with the washing pipe and a stirring part rotationally arranged on the lifting platform, the stirring part is provided with a water passing cavity, the side wall of the stirring part is provided with a plurality of water passing holes, the water passing holes are communicated with the water passing cavity, the flushing pipe is located in the water passing cavity, and the outer wall of the stirring part is further provided with a stirring part. By means of the technical scheme, the problem that in the prior art, existing clean water well washing equipment is low in working efficiency is solved.

Description

technical field [0001] The invention relates to the technical field of well washing equipment, in particular to a groundwater well washing and sampling equipment. Background technique [0002] Well flushing refers to the process of injecting the well flushing medium through the wellbore or drill pipe from the pumping equipment during the workover operation due to engineering needs, and carrying the materials in the wellbore to the surface, thereby changing the properties of the medium in the wellbore to meet the operation requirements. process. [0003] The methods of washing the well include: use the original drilling pump to pump clean water, that is, after changing the slurry with clean water, then continue to wash the well in circulation, which is called clean water well washing; stop the circulation of clean water, and use the piston to continuously move up and down in the well pipe to cause pressure excitement. Destroying the mud skin on the well wall and dredging the...
