An electric fishing tool with eccentric nozzle

Abstract

The invention provides an eccentric water-nozzle electric dropping-fishing tool which comprises a dropping-fishing arm assembly and a first pressure-bearing cylinder and further comprises a circuit control board, a motor, a ball screw, a telescopic casing pipe, a telescopic push-pull rod assembly, a magnetic steel, a Hall switch and a ball screw bracket which are arranged in the first pressure-bearing cylinder. When the dropping-fishing arm assembly makes contact with an eccentric water nozzle, the dropping-fishing arm assembly is subjected to upward force, the telescopic push-pull rod assembly is pushed to drive the magnetic steel to go upwards, the magnetic steel approaches to the Hall switch, the Hall switch is triggered, and the circuit control board controls the motor to work at the time. According to the eccentric water-nozzle electric dropping-fishing tool, a ground instrument can be made to control a dropping-fishing arm of an electric delivery tool to be stretched or closed back at any time, and the water-nozzle detecting function is achieved; and when the electric delivery tool makes contact with the water nozzle, the ground instrument displays, and thus blindness of dropping-fishing of the water nozzle is avoided.

Description

technical field [0001] The invention relates to the field of petroleum logging and testing, in particular to an electric casting and fishing tool with an eccentric water nozzle. Background technique [0002] In the fine water injection process, the eccentric water distributor is equipped with an eccentric faucet that can be cast and fished. The tool used to cast and fish the eccentric faucet is called the eccentric faucet casting tool. [0003] At present, the eccentric spigot casting and fishing tool is mechanical, and the eccentric spigot casting and fishing tool needs to be locked with a lock block on the ground before the eccentric spigot casting and fishing tool goes down the well. When the faucet is cast, put the eccentric faucet casting tool down through the water distributor, and then lift the eccentric faucet casting tool to open the casting arm by collision. [0004] The fishing arm of the eccentric nozzle fishing tool is easily opened by accidental collision dur...
