Description

Technical Field

[0001] This invention relates to the field of downhole equipment maintenance machinery, and in particular to a mobile electromagnetic adsorption drilling and threading integrated device. Background Technology

[0002] Downhole equipment is typically heavy-load equipment, such as conveyors, transfer conveyors, and hydraulic supports. These devices are large in size and have high operating power. The corresponding assembly structural components are also generally made of high-strength metal components. For example, the head of a working face conveyor uses an embedded internal thread structure for all its connecting parts. During downhole use, the high-strength bolts connecting the internal threads of such equipment break extremely frequently under the action of lateral shear force on the external components. After maintenance, it is extremely difficult to handle the high-strength bolts that have broken inside the machine body. At the same time, due to the large size and weight of the equipment, ordinary large drilling and threading machinery cannot be used, and gas cutting equipment cannot be used without damaging the machine body. This is the main factor contributing to the high maintenance costs.

[0003] Specifically, there are two main difficulties. First, the fractured connecting parts are all high-strength bolts of grade 10.9 or higher, making removal difficult due to their high strength. Existing technologies typically utilize welding to weld connecting rods to the fractured bolts and then remove them through these rods. However, due to the high strength of the bolt connections, the success rate of removal is low because the embedded parts within the machine are prone to deformation or corrosion, resulting in very low efficiency. Second, threading after removal is difficult. Currently, commonly used threading machines are usually standalone machines resembling drilling rigs in shape. However, the damaged locations of downhole equipment, or the locations requiring threading, vary, and the large size and limited working space make ordinary machines unusable. The lack of corresponding positioning foundations for threading machines further complicates implementation. In summary, the level of integration of existing technologies for downhole equipment maintenance is generally low. This is the main reason why a large number of downhole equipment needs to be moved out of the well for maintenance and why surface maintenance is inefficient, further contributing to cumbersome work processes.

[0036] A force gauge 14 is also installed on the assembly chain 2.
