no. 1 approach

[0017] First implementation: see figure 1 , a geothermal well wall cleaning device, comprising a fixed plate 1, the left and right sides of the bottom of the fixed plate 1 are fixedly connected with a support plate 2, by setting the support plate 2, it plays the role of supporting the fixed plate 1, the support plate 2 The bottom is fixedly connected with a shelving block 27, and the bottom of the shelving block 27 is fixedly connected with a shock-absorbing pad 28. By setting the shelving block 27 and the shock-absorbing pad 28, the shock resistance of the whole device is improved, and the internal components of the cleaning device are avoided from being damaged by vibration. The left side of the top of the fixed plate 1 is fixedly connected with a rotating motor 3, the output shaft of the rotating motor 3 is fixedly connected with a rotating shaft 4, and the surface of the rotating shaft 4 is fixedly connected with a winding wheel 5, and the surface of the rotating shaft 4 is...

no. 2 approach

[0021] The second embodiment: a geothermal well wall cleaning device, including a fixed plate 1, the left and right sides of the bottom of the fixed plate 1 are fixedly connected with a support plate 2, and the left side of the top of the fixed plate 1 is fixedly connected with a rotating Motor 3, the output shaft of the rotating motor 3 is fixedly connected with a rotating shaft 4, the surface of the rotating shaft 4 is fixedly connected with a winding wheel 5, and the top of the fixed plate 1 is fixed on the right side of the rotating shaft 4 Connected with a stabilizing plate 6, the top on the left side of the stabilizing plate 6 is fixedly connected with a first runner 7, the top of the stabilizing plate 6 is fixedly connected with a second runner 8, and the top on the right side of the stabilizing plate 6 is fixed A third runner 9 is connected, the surface of the reel 5 is wound with a first fixed rope 10, and the end of the first fixed rope 10 away from the reel 5 passes ...

no. 3 approach

[0028] The third embodiment: a method for cleaning the well wall of a geothermal well. A cleaning device is suspended on the ground on both sides of the entrance of the geothermal well through a door-shaped support frame, and the rotating motor and the first fixed rope are used to drive the cleaning device on the support. The cleaning device moves up and down in the well body of the geothermal well. The cleaning device rotates and cleans the well wall while moving downward in the well body stably with the help of the multi-leg support structure arranged up and down adjacent to it and the electric rotary cleaning module with cleaning brushes. When the multi-leg support structure and the cleaning module are in contact with the well wall, the springs in the support structure are self-adaptive and elastic. The electric winding device is composed of a second fixed rope of a certain length pre-rolled on the roller of the winding device. The two ends of the rotating shaft of the rolle...

Abstract

The invention discloses a method for cleaning the well wall of a geothermal well, which comprises the following steps: when a cleaning device first goes out of a well, firstly releasing a section of asecond fixing rope by a mechanical transmission structure; in the process of releasing a second fixing rope body by a roller, linearly pulling a plurality of supporting rollers towards a symmetricalcenter position at the same time, until the outer boundaries of the supporting rollers are smaller than the size of a well entry opening, and then the well entry operation is carried out. After the whole cleaning device enters the well, the reverse operation is carried out, the roller rotates in the reverse direction, drives the mechanical transmission structure to simultaneously push the supporting rollers away from the symmetrical center position to linearly pull and move until all the released rope bodies of the second fixing rope are retracted. Synchronously, a rotating motor on the groundstarts to work, the method solves the problem of low stability system of a geothermal well wall cleaning device, leads the transmission structure to be more stable, improves the stability and safetyof the cleaning process, leads the cleaning efficiency to be high, greatly improves the working efficiency and brings great convenience to users.

Description

technical field [0001] The invention relates to the technical field of geothermal well wall cleaning, in particular to a geothermal well wall cleaning device and a cleaning method. Background technique [0002] Geothermal wells refer to methods and devices for generating electricity from geothermal energy with a depth of about 3,500 meters or hot spring water with a water temperature greater than 30°C. It belongs to high-temperature geothermal; 90℃~150℃, existing in the form of mixture of water and steam, etc., belongs to medium-temperature geothermal; Low temperature geothermal, after completion of geothermal well, due to the long-term use of circulating fluid during drilling, the circulating fluid will form mud skin on the well wall, if not handled properly, it will directly affect the next step of well cleaning operation, common geothermal well wall cleaning The stability of the device is low. Due to the unstable design of the transmission structure, the cleaning process...
