Description

Technical Field

[0001] This utility model belongs to the field of solid phase control devices for oil drilling, specifically a sand flushing device and sand flushing system for cleaning compacted sand at the bottom of drilling fluid tanks. Background Technology

[0002] Oil drilling typically uses 5-7 drilling fluid tanks. The drilling fluid drawn from the well first passes through a vibrating screen into drilling fluid tank No. 0, a triangular tank containing a sedimentation chamber to settle smaller rock cuttings and sand returned from the well that were not screened out by the vibrating screen. When rock cuttings and sand accumulate in the triangular tank over a long period, they become compacted and cannot be naturally discharged from the bottom outlet. Common cleaning methods include manual stirring, where operators use shovels or sticks to stir the fluid manually. This is inefficient, labor-intensive, and fails to thoroughly clean and compact the sediment. Utility Model Content

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0020] The directional terms or positional relationships such as "upper" and "lower" used in the embodiments are based on the drawings in this utility model specification. Figure 1 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0021] Example 1: A sand-flushing device for cleaning compacted sand at the bottom of a drilling fluid tank. like Figures 1-2 As shown, this embodiment includes a liquid supply unit, an execution unit, and a connecting pipeline 5. The liquid supply unit supplies flushing liquid to the execution unit through the connecting pipeline 5, and the execution unit then ejects it at high speed, thereby impacting and loosening the compacted sand at the bottom of the No. 0 drilling fluid tank.

[0022] The liquid supply unit includes a liquid supply tank 1 for storing sand flushing liquid and a pump body 2 placed inside the liquid supply tank 1. The pump body 2 is an existing sewage pump.

[0023] The execution unit includes a flushing gun 3 for rinsing sand and an operating lever 4 mounted on the flushing gun 3 for controlling its spatial position and orientation. In this embodiment, the flushing gun 3 is a conventional welded conical gun, which utilizes a stepped conical nozzle and a tapered design to enhance penetration of compacted sand. The operating lever 4 is an extended lever composed of multiple sections connected by threads, allowing the operator to select the number of sections according to their operating height to achieve a suitable length. During use, the operator holds the operating lever 4 to adjust the position and orientation of the welded conical gun to achieve all-around rinsing of the sand inside the triangular tank 7.

[0024] The inlet end of the connecting pipe 5 is connected to the outlet end of the pump body 2. Specifically, the inlet end of the connecting pipe 5 and the outlet end of the pump body 2 are connected by a threaded pipe 6. The outlet end of the connecting pipe 5 is connected to the inlet end of the flushing gun 3. In this embodiment, the connecting pipe 5 uses an existing water hose, which is flexibly connected to the water hose through a welded conical gun, making it adaptable to different tank structures.

[0025] When using this embodiment, after the pump body 2 is started, the flushing liquid in the supply tank 1 is pumped out, and after passing through the connecting pipeline 5, it is finally ejected at high speed from the nozzle of the flushing gun 3, impacting and loosening the compacted sand in the sand settling chamber 9 of the No. 0 drilling fluid tank (i.e., the triangular tank 7). The loosened sand is discharged from the bottom outlet 8 of the tank, which improves the cleaning efficiency and reduces the labor intensity.

[0026] Example 2 Sand flushing system like Figure 3 , 4 As shown, this embodiment includes the sand flushing device for cleaning compacted sand at the bottom of the drilling fluid tank as described in Embodiment 1, and also includes a triangular tank 7. The fluid supply tank 1 is located below the triangular tank 7 at the position corresponding to the bottom outlet 8, and a sand inlet is provided on the fluid supply tank 1 at the position corresponding to the bottom outlet 8. The fluid supply tank 1 is used to collect the sand flushed down from the triangular tank 7, preventing the sand and mud from directly hitting the ground.

[0027] A discharge pipe 10 is provided between the sand inlet of the supply tank 1 and the bottom outlet 8 of the tank. In this embodiment, the discharge pipe 10 adopts an existing threaded pipe. A valve 11 is installed on the discharge pipe 10, and the valve 11 adopts an existing manual butterfly valve. When it is necessary to clean the sand, open the manual butterfly valve, and then start the pump body 2 to flush with the welded conical gun. After flushing, the flushing liquid, along with the sand, flows out through the bottom outlet 8 of the triangular tank 7 and enters the supply tank 1. The sand accumulates at the bottom of the supply tank 1, and the flushing liquid is located above. It is pumped out by the pump body 2 to flush the sand in the sand chamber 9 of the triangular tank 7 again, realizing the recycling of the flushing liquid and saving water resources.

[0028] It should be noted that as the amount of sediment accumulated in the liquid supply tank 1 increases, in order to prevent the pump body 2 from sucking in sediment, it is necessary to manually lift the pump body 2 occasionally during use so that it is above the sediment and in contact with the flushing liquid.

[0029] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features.
