Description

Technical Field

[0001] This application belongs to the field of hole reamer technology, specifically hole reamers for oil drilling. Background Technology

[0002] Reamers for oil drilling effectively enlarge wellbore diameters, improving drilling efficiency. By using reamers, rock and other materials around the wellbore can be quickly removed during drilling, reducing drilling resistance and increasing drilling speed. Secondly, reamers can enlarge the wellbore in a shorter time, reducing the working time and cost of traditional reaming methods and improving the overall production efficiency of the drilling process. Furthermore, oil drilling reamers are highly adaptable, working stably under different rock formations and geological conditions, especially suitable for complex environments such as hard rock, high pressure, and deep wells. Their design typically features high wear resistance and strength, maintaining stable performance during prolonged high-intensity operation, reducing equipment wear and maintenance costs. The use of reamers not only reduces wellbore damage but also effectively prevents wellbore collapse, improving drilling safety. In addition, oil drilling reamers improve drilling accuracy, ensuring the wellbore size and shape meet design requirements, providing a good foundation for subsequent well completion and oil production. Through proper design, reamers can reduce the need for cement wall protection and casing, lowering construction difficulty and costs.

[0029] Reference Figure 1-4 A borehole reamer for oil drilling includes a base plate 1. The base plate 1 has a rectangular groove inside, and a connecting rod 2 is disposed inside the rectangular groove. The connecting rod 2 has a threaded hole 12 inside, and a threaded connecting post 16 is threadedly connected to the threaded hole 12. A connecting post 14 is fixedly connected to the lower end of the threaded connecting post 16. A gasket 15 is disposed between the connecting rod 2 and the connecting post 14. During the connection and use of the assembly, the connection between the threaded connecting post 16 and the threaded hole 12 facilitates the installation or replacement of the lower reamer head 11 assembly by the operator during subsequent operations. When the reaming head 11 assembly malfunctions, it facilitates timely replacement by the operator, thus enabling subsequent use. During installation, the operator aligns the threaded connecting post 16 with the threaded hole 12, and passes the washer 15 through the threaded connecting post 16 to facilitate connection between the threaded connecting post 16 and the threaded hole 12, thereby strengthening the connection between the components and ensuring the stability of the connection. This facilitates subsequent operation, improves the adaptability of the structure, and makes it easier for the operator to use. By using the connecting rod 2, the lower end of the reaming head 11 assembly can be easily driven, thus facilitating the use of reaming operations in oil drilling.

[0030] Reference Figure 1-2Multiple mounting plates 4 are fixedly connected to the upper end of the mounting base plate 1. The mounting plate 4 has a working groove inside, which provides a position for convenient mounting of the telescopic component 8 and the cylinder component 7, thereby stabilizing the position of the components. The working groove facilitates the telescopic component 8 to move the rectangular working plate 10, and makes it convenient to adjust the working height of the rectangular working plate 10.

[0031] Reference Figure 1-2 The inner top wall of the working groove of the mounting plate 4 is provided with a telescopic component 8, and the upper end of the mounting plate 4 is provided with a cylinder assembly 7. The telescopic component 8 is connected to the cylinder assembly 7, and the position of the telescopic component 8 is connected to the position of the cylinder assembly 7, so as to facilitate the telescopic operation of the telescopic component 8 by using the cylinder assembly 7, thereby facilitating the movement of the rectangular working plate 10 for hole enlargement operation.
