Embodiment

[0046] Example A Quaternary Deep Well Layered Pumping and Stopping Device

[0047] refer to figure 2 , the layered pumping and water-stopping device of this embodiment includes a pump chamber pipe 10, an aqueduct 13, a rubber water-stop air bag 16, and a rubber water-stop plug 21. In this embodiment, the pump chamber pipe 10 is made of a Φ219×8mm seamless pipe , the length is 2500mm, the pipe body is used for the 30×200mm strip window for passing water, and the submersible pump 11 is installed inside, and the upper end of the pump room pipe 10 is connected to the drill pipe through the upper flange 9 and the flange short joint 8 in turn Connector 7, the lower end of the pump chamber pipe 10 is connected to the water guide pipe 13 through the lower flange 12. In this embodiment, the water guide pipe 13 directly uses a Φ89 drill pipe and is connected with a screw.

[0048] In this embodiment, the water-stop airbag is composed of an air line connector 14, an airbag upper plate ...

Abstract

The invention discloses a quaternary deep well layered water pumping and stopping device and a water pumping and stopping method thereof. The device comprises a drilling rod connecting head, a pumpingchamber pipe arranged at the lower portion of the drilling rod connecting head, a water guiding pipe arranged at the lower portion of the pumping chamber pipe, a rubber water stopping air bag arranged on the outer wall of the upper portion of the water guiding pipe, and a rubber water stopping plug arranged on the outer wall of the lower portion of the water guiding pipe. A using method comprisesthe steps of 1), hole drilling and sampling analysis; 2), well drilling; 3), hole punching; 4), well pipe installing; 5), gravel filling and water stopping; 6), well washing; 7), water pumping testing. The deep well layered water stopping device is simple in structure, the defects existing in traditional water stopping methods are overcome, the operation is convenient, the water stopping effect is reliable through actual use, and upper and lower water-containing layers are effectively isolated so that layered water stopping in a pipe in the same well hole can be achieved to achieve the purpose of layered water pumping testing. The layered water pumping and stopping device and method are suitable for performing observation and water pumping testing on different water-containing layers whenhydrographical drilling is conducted.

Description

technical field [0001] The invention relates to a Quaternary deep well layered pumping water stop device and a pumping water stop method thereof, which are suitable for the Quaternary deep well layered water pumping test. Background technique [0002] Layered water stop means that when hydrogeological drilling is carried out in areas with different aquifers (groups), in order to obtain hydrogeological parameters such as water volume, water level, water quality and water temperature of each aquifer (group), it is necessary to separate the water according to different aquifers (groups). Conduct observation and pumping tests. According to the design requirements, at the location of the aquifer, the work of isolating the upper and lower aquifers (groups) of the well and preventing the collusion of the upper and lower aquifers is called layered water sealing. It includes two parts: the water stop outside the pipe and the water stop inside the pipe. The water stop outside the pip...
