Description

TECHNICAL FIELD

[0001] The present application relates to the field of oil extraction equipment, in particular to a wall-mounted submersible cable rapid operation device and a buckle pressing device. BACKGROUND

[0002] At present, with the rapid development of oil and gas extraction equipment, rodless oil extraction is applied more and more widely as a new generation of drilling and extraction technology. As the power cable of the rodless oil extraction technology, the submersible cable needs to be extended to several kilometers deep in the oil well with the unit. The current submersible cable is bound on the surface of the oil pipe through the cable protector. This fixing method makes the oil pipe and the cable become one, and the fixing device of the cable needs to be fixed at the specified position during the well lowering process, which increases the operation difficulty. At the same time, the cable fixing device is not firm, and the cable is easily squeezed with the well wall during the well lowering process, causing the cable damage and increasing the operation cost. Secondly, this fixing method requires the oil pipe and the cable to be lifted together during the well lifting process, which makes the well lifting operation very difficult, the operation is complex, a large amount of manpower and time cost are required, and the cable is also easily damaged during the well lifting process, which cannot meet the secondary use, which brings huge economic loss to the oil field. Therefore, the present application provides a wall-mounted submersible cable rapid operation device to solve the above problems. SUMMARY

[0003] The purpose of the present application is to provide a wall-mounted submersible cable rapid operation device, which has the effect of lifting the submersible cable separately.

[0004] The above technical purpose of the present application is realized by the following technical scheme: a wall-mounted submersible cable rapid operation device, comprising a submersible cable and an oil pipe, a plurality of hooking assemblies are fixedly connected to the submersible cable, the hooking assembly comprises a hook, and a plurality of hooking belts for hooking the hooks are fixedly connected to the outer wall of the oil pipe.

[0005] By adopting the above technical scheme, a plurality of hooking assemblies are arranged on the submersible cable, and a plurality of hooking belts are arranged on the oil pipe. When the submersible cable is connected to the oil pipe, the hooks are inserted into the hooking belts from top to bottom, and the submersible cable is inserted into the submersible motor or the submersible pump, etc. The relative fixation of the oil pipe and the submersible cable is realized, and the oil pipe and the submersible cable are lowered into the well together during the well lowering process. During the well lifting process, the hooks on the hooking assembly are separated from the hooking belts from bottom to top, the cable is slowly pulled out from the steel belt first, and then the well lifting work of the oil pipe assembly is processed after the submersible cable lifting is completed, so that the oil pipe and the submersible cable are lifted separately, the operation is fast, and the submersible cable is protected.

[0006] Further provided in the present application is that the hook is inserted between the hooking belt and the oil pipe to form a hooking.

[0007] By adopting the above technical solution, the hook is inserted between the hook belt and the oil pipe to form a hook. After the hook is completed, the hook belt pulls the hook to fit the outer wall of the oil pipe, thereby increasing the static friction between the hook and the oil pipe and improving the stability of the submersible cable when it is lowered into the well.
