Thread sealing grease gun

Abstract

The invention provides a thread sealing grease gun. The thread sealing grease gun comprises a gun body (10), and a head (20) which is arranged at one end of the gun body (10), wherein a closed cavity (111) for storing sealing grease is formed in the gun body (10); a sealing grease outlet (23) is formed in the head (20); a piston (17), which is used for extruding the sealing grease in the closed cavity (111) and discharging the sealing grease from the sealing grease outlet (23), is arranged in the gun body (10). The thread sealing grease gun further comprises a rotating and grease discharging driving part which can drive the head (20) to rotate while driving the piston (10) to extrude the sealing grease in the closed cavity (111). According to the thread sealing grease gun, a handle can be rotated to drive the head to rotate, and meanwhile, the piston can be pushed to extrude the thread sealing grease to flow out from the sealing grease outlet in the head, thus achieving the purpose of uniformly coating the sealing grease on inner threads in a coupling of an oil pipe.

Description

technical field [0001] The invention relates to a thread sealing grease gun capable of applying thread sealing grease to threads. Background technique [0002] During downhole construction, before the tubing that needs to withstand internal pressure is run into the well, when the pressure test string or pump string is lowered, the thread sealant must be evenly applied to the tubing thread to prevent the string from leaking. At present, the application method of oil pipe thread sealant is very simple. Most of them use bamboo chips or wooden sticks to take an appropriate amount of thread sealant and apply it evenly on the inner thread of the oil pipe coupling. The existing method cannot formulate operating specifications, and cannot guarantee the uniformity of thread sealant application. Contents of the invention [0003] In order to solve the problem that the existing method cannot ensure that the thread sealant is applied evenly on the outside of the thread, the invention...

Problems solved by technology

[0003] In order to solve the problem that the existing method cannot ensure that the thread sealant is applied evenly on the outside of the thread, the invention provides a thread sealant gun, which can drive the head of the sealant gun to rotate through the rotation of the handle, and at the same time push the piston to compress The thread sealant overflows from the sealant outlet of the gun head, so as to achieve the purpose of evenly spreading the sealant on the inner thread of the oil pipe coupling
