Description

Technical Field

[0001] This utility model relates to the field of drilling and grinding tools, specifically a drilling and grinding tool for quickly drilling bridge plugs. Background Technology

[0002] A quick-drilling bridge plug is a commonly used device in the oil and gas industry, mainly used in downhole operations. It is typically used to isolate or seal off a certain area or to isolate the flow of liquids and gases in downhole operations. It is commonly used in well workover, plugging, or temporary sealing operations in oil and gas wells. After installation, the quick-drilling bridge plug needs to be removed when the wellbore needs to be used again, which requires the use of drilling tools.

[0003] Existing drilling tools typically involve installing a drill bit, which is prone to damage after prolonged use and requires replacement. Current drill bits are connected to the rotating shaft via threads, necessitating the use of various tools to remove them, making the process cumbersome. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a drilling tool for a fast-drilling bridge plug to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling tool for a fast-drilling bridge plug, comprising a connecting seat, a fixing block fixed on one side of the connecting seat, a screw fixed on one side of the fixing block, a protrusion fixed on one side of the connecting seat, a drill bit sleeved on the outer wall of the protrusion, a slot formed on the outer wall of the protrusion, a insertion rod installed on the outer wall of the drill bit, a blocking block installed on the outer wall of the drill bit, and a limit groove formed on one side of the drill bit.

[0006] By adopting the above technical solution, when it is necessary to replace the drill bit, it is only necessary to use hex bolts to remove the blocking block from the outside of the drill bit and take out the insert rod to disassemble the drill bit. There is no need to disassemble the connecting seat, which improves the efficiency of drill bit installation and disassembly. The two sets of insert rods make the drill bit installation more stable and prevent it from falling off during operation. Moreover, the tapered drill bit can better drill the fast drilling bridge plug.

[0007] The present invention is further configured such that the drill bit has an insertion hole inside, and the inner wall of the insertion hole fits against the outer wall of the insertion rod.

[0008] Preferably, the provided insertion hole can cooperate with the insertion rod to limit the movement direction of the insertion rod and prevent the insertion rod from moving.

[0009] The present invention is further configured such that the outer wall of the drill bit is provided with a threaded groove, the inner wall of the threaded groove matches the blocking block, and a hexagonal groove is provided on one side of the blocking block.

[0010] Preferably, the threaded groove allows the end of the hexagonal bolt to enter the groove during use. Rotating the hexagonal bolt fixes the blocking block within the threaded groove, preventing the blocking block from moving.

[0011] The present invention is further configured such that a limiting piece is fixed at one end of the insertion rod, and the diameter of the limiting piece is larger than that of the insertion rod.

[0012] Preferably, a limiting piece is provided to limit one end of the insertion rod, avoiding the problem of the insertion rod being difficult to remove and increasing the weight of the insertion rod.

[0013] The present invention is further configured such that an avoidance groove is provided on the other side of the blocking block.

[0014] Preferably, by creating a clearance groove, when the blocking block is installed inside the threaded groove, the limiting piece enters the interior of the clearance groove, thereby avoiding the problem of the blocking block protruding.

[0015] The present invention is further configured such that the number of the insertion rods is two sets, and the two sets of insertion rods are symmetrically arranged about the vertical center line of the drill bit.

[0016] Preferably, the two sets of insert rods make the drill bit installation more stable and prevent the drill bit from shaking.

[0017] The present invention is further configured such that a sealing gasket is fixed on one side of the connecting seat, and a groove is provided on one side of the drill bit.

[0018] Preferably, the sealing gasket is designed to fit into the groove, thereby preventing leakage at the connection between the drill bit and the connector.

[0019] The present invention is further configured such that the inner wall of the limiting groove is inclined and one end of the protrusion is inclined.

[0020] Preferably, the protrusions with beveled surfaces can easily enter the interior of the limiting groove.

[0021] In summary, the present invention has the following main advantages: 1. This utility model is equipped with a drill bit, a protrusion, a plug rod, a limiting groove, and a blocking block. When the drill bit needs to be replaced, only a hexagonal bolt is needed to remove the blocking block from the outside of the drill bit and take out the plug rod to disassemble the drill bit. There is no need to disassemble the connecting seat, which improves the efficiency of drill bit installation and disassembly. The two sets of plug rods make the drill bit installation more stable and prevent it from falling off during operation. Moreover, the tapered drill bit can better drill the fast drilling bridge plug.

[0022] 2. This utility model features a sealing gasket and a groove. The sealing gasket and groove work together to seal the connection when the connecting seat is connected to the drill bit. This prevents liquid from entering the connection and makes the drill bit work more stably. Attached Figure Description
