Description

Technical Field

[0001] This utility model relates to the field of mineral exploration engineering technology, and in particular to a drilling mud monitoring and early warning system. Background Technology

[0002] Drilling is a technical method that uses mechanical equipment to drill holes into the ground to obtain rock and mineral samples, explore resources (such as oil, natural gas, and minerals), conduct geological surveys, or implement engineering projects (such as hydrological wells, geothermal wells, and pile foundation construction). Its core principle is to break the rock with a drill bit, using the drill rod to transmit power and circulate a medium (such as drilling mud) to cool the drill bit and remove rock cuttings, ultimately forming a borehole that meets the required specifications. Drilling is widely used in energy development, geological research, and engineering construction, and is an important means of resource exploration and the utilization of underground space.

[0003] Drilling mud is the core medium in drilling engineering. It cools the drill bit, carries cuttings, stabilizes the borehole wall, balances formation pressure, and transmits power, ensuring drilling efficiency and construction safety. Drilling mud is known as the lifeblood of drilling and plays a vital role in the quality of drilling operations.

[0004] During drilling operations, insufficient mud flow can lead to the inability to dissipate frictional heat from the drill bit in a timely manner, causing a sharp rise in drill bit temperature and potentially resulting in sintering, deformation, or even burnout. Simultaneously, it reduces the mud's cuttings-carrying capacity, leading to cuttings accumulation and exacerbating secondary grinding, increasing frictional heat generation. Furthermore, insufficient flow weakens the lubricating effect of the mud, intensifying direct friction between the drill bit and the rock. In deep holes or high-pressure formations, excessively low flow can disrupt the bottom hole pressure balance, indirectly causing abnormal heating of the drill bit. Different formations and drill string combinations have minimum required mud flow thresholds; once these thresholds are fallen, the risk of drill bit burnout increases significantly. Therefore, rationally controlling mud flow is one of the key measures to prevent drill bit burnout. Currently, there is an urgent need to develop a device that can effectively monitor mud flow and provide early warning. Utility Model Content

[0005] To address the issue of drill bit burn-out caused by the inability to monitor mud flow rate in the prior art, this invention provides a drilling mud monitoring and early warning system.

[0006] The technical solution of this utility model is as follows: This utility model is a drilling mud monitoring and early warning system, which is special in that: the drilling mud monitoring and early warning system includes a mud pump, a first high-pressure hose, an electromagnetic flowmeter, a display, a check valve, a second high-pressure hose, and a drill pipe. The mud pump is connected to the electromagnetic flowmeter through the first high-pressure hose. The electromagnetic flowmeter is connected to the display. The electromagnetic flowmeter is connected to the check valve through a flange. The check valve is connected to the second high-pressure hose. The second high-pressure hose is connected to the drill pipe.

[0007] Furthermore, the drilling mud monitoring and early warning system also includes a third high-pressure hose, which is connected to the second high-pressure hose via a tee connector, and the third high-pressure hose is connected to the drill pipe.

[0008] Furthermore, a water tap is installed on the third high-pressure hose.

[0011] Furthermore, the first high-pressure hose is connected to the electromagnetic flowmeter via a first flange with a reduced diameter.

[0012] Furthermore, the check valve is connected to the second high-pressure hose via a second flange with a reduced diameter.

[0013] The drilling mud monitoring and early warning system provided by this utility model employs a device structure in which mud flows into a first high-pressure hose via a mud pump, and the flow rate data is fed back to a display in real time via an electromagnetic flowmeter. A tap on a third high-pressure hose controls the flow rate of mud into the drill pipe. Therefore, this utility model has the following advantages:

[0014] 1. Simple structure: The structure of this utility model is simple. The device is directly embedded into the mud circulation pipeline through the flange structure, without the need to modify the existing drilling equipment. It is compatible with different pipe diameters, and is easy to install, operate and maintain.

The mud pump 16 is connected to the electromagnetic flowmeter 4 via the first high-pressure hose 1 and the first flange reducer 3. The electromagnetic flowmeter 4 is connected to the display 2. The electromagnetic flowmeter 4 is connected to the check valve 6 via the flange 5. The check valve 6 is connected to the second high-pressure hose 8 via the second flange reducer 7. The second high-pressure hose 8 is equipped with a tee connector 9, which connects to the third high-pressure hose 12 and the return water pipe 11 respectively.

The flow data detected by the electromagnetic flow meter 4 is fed back to the display screen 2 for monitoring and early warning. The mud flows through the check valve 6 to ensure that it can only flow from the pump to the drill pipe 15 and will not flow back due to pump shutdown or pressure fluctuation. The flow rate of mud entering the drill pipe 13 is adjusted by the faucet 14. The return water valve 10 is opened, and excess mud flows out through the return water pipe 11.
