Description

Technical Field

[0001] The utility model relates to the field of oil mining, in particular to a drilling device for oil mining with good protection performance. Background Art

[0002] Drilling equipment for oil production refers to the mechanical equipment used to drill for oil and natural gas underground. It mainly includes components such as drilling rigs, drilling towers, mud pumps, drill bits, rotary tools, and power systems. These devices play a vital role in the oil production process.

[0003] Existing technologies, such as CN206267796U, describe a drill bit for oil production. This utility model relates to the technical field of oil production. A drill bit connection column is provided at the upper end of a connecting shaft, and a drill bit base is provided at the upper end of the column. The drill bit base is equipped with several cutting tools embedded with several diamonds, and a guide hole is provided in the middle of the drill bit base. One side of the cutting tool is provided with a slot, and two sides of the slot are provided with inserts, each of which has several perforations. The cutting tools, slot, and inserts form an "I"-shaped insert. The drill bit base has several slots, and two sides of the slots are provided with groove bodies. The groove bodies are provided with screw holes corresponding to the perforations. The "I"-shaped insert is inserted into the drill bit base through the cooperation of the inserts and the groove bodies, and is secured by screws in the screw holes. This device can adapt to the hardness requirements of different rock layers. If the cutting edge is damaged, the entire drill bit does not need to be replaced, greatly reducing investment costs and enhancing practicality.

[0004] In order to solve the problem of replacing the drill bit of the existing equipment, the drill bit in the existing equipment is used, because some rocks are relatively hard, which will cause the blade on the drill bit to be damaged. Due to long-term work, the drill bit is subjected to excessive pressure and will generate a large vibration force, which can easily cause the thread to loosen due to vibration, and then cause the drill bit to be loosened or fall off, affecting the progress of oil extraction, and it is not convenient to alleviate the hard impact force of the drill bit during the drilling process. When the drill bit just starts to drill, its impact force is mostly large, and the drill bit directly impacts the ground hard, which easily causes a high risk of damage to the drill bit. The drill bit needs to be replaced regularly, which is more consumable and needs to be improved. Utility Model Content
