Description

Technical Field

[0001] This utility model relates to the field of oil and gas drilling technology, and in particular to an oiling device for drill thread. Background Technology

[0002] Pipes are essential tools in oil and gas drilling. During the drilling process, multiple pipes are usually connected end to end in the well. The pipes are connected by threads at their ends. During use and storage, the threads at the ends of the pipes often become rusty and scaled. In order to protect the quality and performance of the pipes, the threads at the ends of the pipes are usually cleaned and then grease is applied before operation to prevent affecting the service life and performance of the pipes.

[0003] Currently, after the pipe fitting seat is positioned at the wellhead, before connecting the pipe fitting, the internal threads of the pipe fitting are cleaned and grease is applied manually. Due to the limited working space at the wellhead, the workload of applying grease manually is large and labor-intensive. It takes a long time to apply the grease evenly to the threads, which not only poses a safety hazard of injury to personnel but also seriously affects the efficiency of the operation.

[0004] Therefore, there is an urgent need for a high-safety and high-efficiency oiling device for drill thread. Utility Model Content

[0024] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0025] like Figure 1 As shown, this embodiment provides an oiling device for drill bit threads, including a mounting base 1, a driver 2, a folding arm, and an oiling block 3. The driver 2 is mounted on the mounting base 1, one end of the folding arm is rotatably mounted on the mounting base 1, and the other end of the folding arm is connected to the oiling block 3. The driver 2 is connected to the folding arm to drive the folding arm to extend and fold, thereby causing the oiling block 3 to move closer to and away from the drill bit threads. In this embodiment, the driver 2 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0026] Specifically, when oiling is required, the actuator 2 drives the folding arm to extend, causing the oiling block 3 to approach and abut against the drill string threads for oiling. After oiling is completed, the actuator 2 drives the folding arm to retract, causing the oiling block 3 to move away from the drill string threads, thus completing the operation. Compared with existing technologies, this method has a high degree of mechanization, enabling unmanned oiling operations and greatly improving both operational efficiency and safety.

[0027] Furthermore, such as Figure 1 As shown, the folding arm includes a front arm 41 and a rear arm 42. The driver 2 is connected to the front arm 41. One end of the front arm 41 is rotatably mounted on the mounting base 1 as a point of the folding arm. The other end of the front arm 41 is rotatably connected to one end of the rear arm 42. The other end of the rear arm 42 is connected to the oiling block 3 as the other end of the folding arm. Specifically, the front arm 41 is composed of two parallel connecting arms 411, which are a first connecting arm and a second connecting arm. The first connecting arm is closer to the driver 2 than the second connecting arm, and the driving end of the driver 2 is connected to the second connecting arm.

[0028] Furthermore, such as Figure 2 As shown, the oiling block 3 has an arc-shaped surface that conforms to the drill bit threads, and an oiling thread 31 is provided on the arc-shaped surface. In this embodiment, multiple oil outlets 32 are evenly provided on the oiling thread 31, and the multiple oil outlets 32 are connected to the oil inlet 43 on the folding arm. Specifically, the oil inlet 43 is provided on the rear arm 42. After the oiling thread 31 on the arc-shaped surface abuts against the drill bit threads, thread oil is injected from the oil inlet 43 and applied to the drill bit threads through the multiple oil outlets 32. The oiling thread 31 and the multiple oil outlets 32 enable the thread oil to be evenly applied to the drill bit threads.

[0029] Furthermore, in this embodiment, the number of oiling bodies formed by the mounting base 1, the driver 2, the folding arm, and the oiling block 3 is two, and the two oiling bodies are arranged symmetrically. It should be noted that the number of oiling bodies is only an example; if the number of oiling bodies is three or more, they will be arranged in a circular pattern.
