Problems solved by technology

However, the demand for refined and mechanized maintenance has not yet been developed, and the research and development of intelligent portable maintenance equipment is still in a blank stage
This conventional method not only has high labor intensity, low efficiency, uneven application, but also causes great environmental pollution and easy waste of raw materials.
However, mass production practice shows that the grease must be applied evenly and the thickness is between 1 / 32in-1 / 16in to achieve the best protection effect, and the traditional manual oiling cannot meet the operation requirements

Embodiment 1

[0105] This embodiment illustrates the structure and working process of the thread maintenance system of the present application by taking the 8-inch thread on the external drill collar as an example.

[0106] See Figure 1-2 , The thread maintenance system of this embodiment includes a thread cleaning device, a thread air drying device and a thread grease spraying device, respectively forming a thread cleaning channel, a thread air drying channel and a thread spraying channel.

[0107] Wherein, the thread cleaning device includes a high-pressure cleaner 11, a thread cleaning gun head 12 and a cleaning fluid pipeline 13, one end of the cleaning fluid pipeline 13 is connected to the high-pressure cleaner 11, and the other end is connected to the thread cleaning gun. Header 12 connections. The high-pressure cleaner 11 can provide auxiliary functions such as heating to generate high-temperature steam, and the mixing ratio of cleaning agent and water can be adjusted.

Embodiment 2

[0132] This embodiment takes the 8-inch thread on the inner button drill collar as an example for illustration.

[0133] See Figure 11-14 , the difference between the thread maintenance system of the present embodiment and embodiment 1 is only:

[0134] The nozzles on the cleaning rod 124 of the threaded cleaning gun head 12 and the nozzles on the spraying rod 324 on the threaded grease spraying gun head 32 are facing away from the first mechanical rotary joint 122 and the second mechanical rotary joint 122 respectively. Type rotary joint 322 is set;

[0135] Both the first sealing cover 125 and the second sealing cover 325 are relatively short, and the first mechanical rotary joint 122, the first rotary joint connector 123, the cleaning rod 124 and the second mechanical rotary joint are not connected together. The swivel joint 322 , the second swivel joint connector 323 , and the spraying rod 324 can be airtightly connected to the inner buckle drill collar so as to form a ...

Abstract

A thread cleaning gun head comprises a first rotation connector, a first rotation connector connecting piece fixed to the first rotation connector, a cleaning rod arranged on the first rotation connector connecting piece, and a first pipeline connector. The cleaning rod comprises a cleaning arm, and the cleaning arm is arranged to extend in the axis direction of the first rotation connector. The cleaning arm is provided with a brush and a nozzle. The first pipeline connector is connected with the first rotation connector connecting piece. The invention further provides a thread cleaning device, a thread grease spraying gun head and device and a thread maintaining system. The thread maintaining system and the thread cleaning and grease spraying gun head and device thereof are high in automation degree and good in cleaning effect, and the grease applying thickness is easy to control.

Description

technical field [0001] This application relates to but not limited to the maintenance technology of drilling tool threads, specifically to but not limited to a thread maintenance system and its thread cleaning gun head and device, thread grease spraying gun head and device. Background technique [0002] Downhole oil extraction tools generally use internal and external threads with a set torque to connect and lengthen for drilling and production operations. In the whole operation process, the thread needs to be connected and disassembled frequently, so the fineness of the maintenance of the thread "protection wire" directly determines the timeliness and labor intensity of the entire operation process. [0003] Usually, after the drilling tool is transported back to the land, the flaw detection and "checking" should be carried out first, and then the "wire protection" maintenance should be carried out on the thread to prepare for operation. According to the investigation, Sch...
