An up-tilt three-way rigid contact hole sensor installation and recovery device

Abstract

The present invention discloses an updip type three-way rigid contact hole installed sensor installing and recycling device. The device comprises a sensor and also comprises a butting shell, the bottom of the butting shell is connected with the sensor detachably, and the top end of the butting shell is equipped with an epoxy resin fixing hole in which an epoxy resin colloid is arranged. The device also comprises a tray on which a cup is fixed, the concrete or epoxy resin is arranged inside the cup, and the tray is equipped with a second threaded rod used for inserting in the epoxy resin colloid. The updip type three-way rigid contact hole installed sensor installing and recycling device of the present invention better solves the problems that the sensor and the hole wall are difficult to couple during the updip type drill hole, the sensor is difficult to install in the updip type drill hole, avoids the situation that the sensor installation is limited by the drill hole angle and the gravity, and is convenient to recycle the sensor.

Description

technical field [0001] The invention relates to the field of microseismic monitoring, in particular to an upward-inclining three-way rigid contact hole sensor installation and recovery device. It is suitable for reservoir water storage, nuclear waste storage, underground storage of greenhouse gases, geothermal engineering, safe operation of open slopes, fault orientation of oil and gas exploitation, oil production stability of oil and gas wells, rockburst induced by mining, roof collapse, ground pressure shock Disaster safety monitoring, assessment and management. Background technique [0002] Microseismic (microseismic) is a small earthquake, which is caused by the accumulation of energy in the rock itself in a local area to a certain extent, and the cracks and destruction inside the rock are induced by external disturbances, and the accumulated energy is released in the form of elastic waves. Micro vibration. Microseismic monitoring technology is one of the important mea...

Problems solved by technology

Although the monitoring effect of this installation method is better, as the project progresses, the continuous installation of new sensors will inevitably increase the monitoring cost, resulting in a lot of waste, and once the sensor of this installation method has a problem, it cannot be repaired and replaced. , thereby affecting the monitoring effect; the second is the recyclable installation method, which is mostly designed for specific engineering conditions, such as the installation and recovery of all-round deep holes in fractured rock mass, the installation and recovery of deep holes in water-bearing weak rock and soil, Reverse thread installation and recovery at the bottom of the borehole, simple mechanical installation and recovery of the wedge body, etc. These installation and recovery methods have not yet involved the installation and recovery of the three-way rigid contact sensor for the upward-inclining drilling. For the existing installation and recovery of the upward-inclining drilling The recovery technology still has the following difficulties and deficiencies: 1) It is difficult to achieve good coupling between the three directions of the sensor and the hole wall, which greatly affects the signal reception of microseismic monitoring, resulting in the loss of valuable data, which affects disaster prediction and forecasting. Accuracy; 2) Due to various reasons such as gravity, couplant, connection, etc., the sensor is easy to fall off in the upward drilling, and the sensor has a greater risk of damage
