Embodiment Construction

[0010] In order to further disclose the technical solution of the present invention, the following is a detailed description with embodiments in conjunction with the accompanying drawings of the specification:

[0011] The present invention consists of a main body 1 and tungsten steel cutting heads 4, 5. The main body 1 is cylindrical, the upper part is provided with a tubing female button 2, the center is provided with a cutting fluid channel 3, and the lower circumference is symmetrically provided with tungsten inserts The right-angled acute triangle and isosceles three trapezoidal grooves of the steel cutting head; correspondingly inlaid with the right-angled acute triangle tungsten steel cutting head 5 and the isosceles trapezoidal tungsten steel cutting head 4 in the groove. In the application, if it is to cut the tail of the tubing to fish the sucker rod, use the tubing to lower the fast cutter of the tubing tail to the tail of the tubing, turn the rig turntable to start cut...

Abstract

The invention relates to a fast oil pipe fish tail cutter which consists of a body and a tungsten steel cutting head and is characterized in that the body is designed to be a cylinder shape, the upper part of the body is provided with an oil pipe box, the center of the body is provided with a cutting fluid flow passage, the periphery of the lower part of the body is symmetrically provided with a right angle and acute angle triangle and isosceles trapezoid slot embedded with the tungsten steel cutting head, and a right triangle tungsten steel block and an isosceles trapezoid tungsten steel block are embedded in the slot. In the process of cutting the oil pipe fish tail, the cutter firstly cuts out a conical surface on the oil pipe fish tail and then cuts off the conical tip, thus shortening cutting time, speeding up the cutting, and gaining time for salvage and well repairing work.

Description

1. Technical Field [0001] The invention relates to a fishing tubing used in workover in an oil field and a quick cutter for tubing fish tails for fishing sucker rods. 2. Background technology [0002] During the production process of the oil well, due to the corrosion of the sewage in the oil, the tubing was perforated and broken off and the sucker rod was corroded and broken off, so it was necessary to stop production for salvage and workover. If the sucker rod breakage point is inside the fish tail of the tubing, you need to use a cutter to cut off the tail of the tubing to expose the sucker rod and then use the sucker rod salvage device to fish the sucker rod. If the oil pipe is salvaged, the tail part must Cut off the tubing and then use the tubing salvage device to salvage the tubing. The current oil pipe fish tail cutters are flat cut, and the cutting speed is relatively slow. It takes a long time to complete a fishing job, which seriously affects the production time rate o...
