Problems solved by technology
[0002] Downhole staff are responsible for the installation, commissioning, maintenance, and calibration of the detection devices of the well monitoring system within the jurisdiction. Many existing sophisticated in-well detection procedures are limited by existing technologies, and staff still need to carry detection instruments downhole for detection. The detection instrument needs to install power supply facilities in the well in advance. Most of the staff enter the well through ropes or ladders. When performing detection operations, there are many safety hazards. It is difficult to illuminate the well and supply power to the detection instrument, which affects the work efficiency of the staff.

The invention discloses a crawling ladder for in-well detection. The crawling ladder comprises a ground surface, a drilling platform is fixedly arranged on the top end face of the ground surface, a drilling working cavity is formed in the drilling platform in an up-down penetrating mode, and the top end face of the drilling working cavity is in communication with a well body arranged in the groundsurface. The crawling ladder is convenient to use, a climbing frame and a cable are carried by a bottom frame installed in the drilling platform to descend into a well, the situation in the well is transmitted back to the ground through a camera on the bottom frame, and after it is confirmed that the well is safe, a worker goes down to the well for detection through the crawling ladder; and the crawling ladder can avoid installed facilities in the well and be fixed to the wall of the well in the descending process of the worker, the cable can supply power to an illuminating lamp on the crawling ladder and a detection instrument carried by the worker, a safe and convenient working environment is created for the worker, the detection working efficiency of the worker is improved, the application range is wide, and the crawling ladder is worthy of application and popularization.
Description
technical field [0001] The invention relates to the technical field of downhole detection, in particular to a climbing ladder used for downhole detection. Background technique [0002] Downhole staff are responsible for the installation, commissioning, maintenance, and calibration of the detection devices of the well monitoring system within the jurisdiction. Many of the existing sophisticated in-well detection procedures are limited by the existing technology, and it is still necessary for the staff to carry detection instruments into the well for detection. The detection instruments need to be equipped with power supply facilities in the well in advance. Most of the workers enter the well through ropes or ladders. During the detection operation, there are many safety hazards. It is difficult to illuminate the well and supply power to the detection instruments, which affects the work efficiency of the staff.
