[0019] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connection", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral connection; the connection can be a mechanical connection or an electrical connection; the connection can be a direct connection or an indirect connection through an intermediate medium, and can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] A long-distance mud discharge tooling comprises: a slurry discharge pipeline 1, a quick-opening valve, a transfer water tank 3 and a transfer pump 4, wherein the slurry discharge pipeline 1 is provided with a first quick-opening valve 201, a hole is opened on the wall of the slurry discharge pipeline 1 and connected to the transfer pump 4 through a pipeline, a second quick-opening valve 202 is provided on the pipeline, a hole is opened on the wall of the slurry discharge pipeline 1 and connected to the transfer water tank 3 through a pipeline, a second quick-opening valve 202 is provided on the pipeline.

[0021] The slurry discharge pipeline 1 is a steel pipe 101 welded with a flange 102 , and a plurality of slurry discharge pipelines 1 are boltedly connected via the flanges 102 , and rubber gaskets are arranged between the flanges 102 .

[0022] A handrail 7 and a sidewalk 6 are provided beside the transfer water tank 3 .

[0023] The tooling adopts a unit modular structure, can be quickly disassembled and replaced, and uses low-power equipment to solve problems such as the risk of high pressure in long-distance mud transportation. It is suitable for various working environments, with simple equipment, easy operation, high construction guarantee rate and low construction cost.

[0024] The unit components are adopted, the slurry discharge pipe 1 is a steel pipe 101, flanges 102 are welded on both sides of the steel pipe 101, and the slurry discharge pipes 1 are assembled and connected by flanges 102, which can adapt to any length of conveying, and can be replaced at any time if the pipe is blocked.

[0025] The quick-opening valves include the “slurry stop valve set on the main pipeline” and the “slurry inlet valve and slurry outlet valve connected to the drilling rig or transfer water tank”. The main pipeline slurry stop valve is used to open and close the pipeline.

[0026] The transfer pump 4 and the transfer water tank 3 are set at an interval of 200m. The setting distance is determined according to the head of the drilling rig circulating pump and should be less than the head distance of the circulating pump. The transfer pump 4 can be of the same power as the drilling rig circulating pump, and its function is to transfer and transport.

[0027] The slurry discharge pipeline 1 adopts unit components, which are easy to assemble and replace, and can adapt to the assembly of pipelines of any length; the transfer water tank 3 and the mid-mounted pump 4 are set, and there is no need to set up a high-power slurry discharge pump, which fully utilizes the reverse circulation drilling rig or mud suction equipment and other self-owned equipment, and avoids the safety risk of high pressure in the long-distance transmission pipeline of a high-power slurry discharge pump.

[0028] The slurry discharge pipeline 1 is welded with steel pipe 101 and flange 102. The length of steel pipe 101 is determined according to the on-site transportation distance, and 3m, 6m, and 9m are generally set as standard sections; steel pipe 101 is directly determined according to the on-site slurry discharge volume per unit time, which is generally 1.2 times the maximum slurry discharge volume; flange 102 is directly matched with steel pipe 101, and flanges 101 are connected with high-strength bolts, with rubber gaskets in the middle. If individual slurry discharge pipelines 1 are blocked on site, the unit section can be replaced at any time.

[0029] At the reverse circulation drilling rig or mud suction equipment, under normal construction conditions, the three valves are all open, and the valves on both sides are connected to the transfer pump 3, which transports mud to the slurry discharge pipe 1; if the slurry discharge pipe 1 is blocked, close the main pipe valve (80 valve) and the valve on the blocking side (40 valve) to ensure that the slurry discharge system operates normally while the blocked side is replaced and repaired.

[0030] At the transfer water tank 3, under normal construction conditions, the main pipeline valve (80 valve) is closed, and the valves on both sides (40 valves) are opened. One side is the slurry discharge pipeline 1 entering the transfer water tank 3 pipeline 5, and the other side is the transfer water tank 3 entering the slurry discharge pipeline 1 pipeline 5; when the slurry discharge cycle is long, open the main pipeline valve (80 valve) at intervals of 3-5 days, and close the valves on both sides (40 valves) once, lasting about 30 minutes, to remove the accumulation at the valve.

[0031] The interval between the transfer water tanks 3 is determined by the lift of the mud pump, which mainly solves the problem of high pressure transportation over long distances in the slurry discharge pipeline 1 and provides power for subsequent pipeline slurry discharge.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any modification, equivalent replacement and improvement made by any technician familiar with the technical field within the technical scope disclosed by the utility model and within the spirit and principle of the utility model shall be covered by the protection scope of the utility model.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
