Abstract
Description
Technical Field
[0001] This utility model relates to the field of mud transportation technology, specifically a transportation pipeline for mud transfer. Background Technology
[0002] Drilling is the process of using mechanical equipment or manpower to drill holes into the ground to create boreholes. It typically refers to the drilling of wells for exploring or developing liquid and gaseous minerals such as oil and natural gas, as well as large-diameter water supply wells. Drilling has extremely wide applications in national economic construction. The drilling mud produced is pumped into a temporary storage tank, and then transported through pipelines to a mud treatment tank. The treated mud is then pressed into a filter press to form a mud cake, completing the dewatering process. Because the mud contains a large amount of sand and gravel, the sand and gravel entering the filter press affects the dewatering effect and also reduces the service life of the filter press. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a conveying pipeline for mud transfer, thereby solving the deficiencies of the prior art.
[0004] The purpose of this utility model is achieved through the following technical solution: a conveying pipeline for mud transfer, including a mud storage tank, the bottom of which is connected to a mud conveying pipe and a sewage discharge pipe, the mud conveying pipe being connected to a mud pump, the inner bottom surface of the mud storage tank being inclined, a mud hole being opened at the high end of the inner bottom surface of the mud storage tank, the mud conveying pipe being connected to the mud hole, a sewage discharge hole being opened at the low end of the inner bottom surface of the mud storage tank, the sewage discharge pipe being connected to the sewage discharge hole, and a filter screen being installed on the inner bottom surface of the mud storage tank at the position of the mud hole.
[0005] Furthermore, a flange is fixedly fitted at the bottom of the sewage pipe, and a plug is connected to the flange.
[0006] Furthermore, an annular sealing ring is fixed on the top surface of the plug, and an annular groove is provided at the bottom of the drain pipe. The axial length of the annular sealing ring is greater than the axial depth of the annular groove, and the annular sealing ring is interference-fitted into the annular groove.
[0007] Furthermore, the filter screen is installed on the inner ring of the annular disc, which is connected to the mud storage tank by screws.
[0008] Furthermore, a manhole is provided at the top of the mud storage tank, the manhole is connected to the inner cavity of the mud storage tank, and a ladder is installed on the inner wall of the mud storage tank.
[0009] Furthermore, a sealing groove is provided around the manhole on the top of the mud storage tank, and a counterweight plug is adapted to be installed in the sealing groove.
[0010] Furthermore, an annular sealing gasket is fixed on the step formed by the sealing groove and the manhole, and the counterweight plug compresses and deforms the annular sealing gasket.
[0011] The beneficial effects of this utility model are:
[0012] The mud in the mud storage tank is transported to the treatment tank through the mud delivery pipe. Before entering the mud delivery pipe, the mud is filtered through a filter screen to prevent large particles of sand and gravel from entering the mud delivery pipe. This prevents the mud delivery pipe from transporting sand and gravel into the subsequent mud treatment station and does not affect the subsequent mud treatment operations.

Detailed Implementation
[0017] Example 1
[0018] like Figures 1 to 3As shown, a conveying pipeline for mud transfer includes a mud storage tank 1. The bottom of the mud storage tank 1 is connected to a mud conveying pipe 2 and a drain pipe 4. The mud conveying pipe 2 is connected to a mud pump 3. The inner bottom surface of the mud storage tank 1 is inclined. A mud hole 5 is opened at the high end of the inner bottom surface of the mud storage tank 1, and the mud conveying pipe 2 connects to the mud hole 5. A drain hole 6 is opened at the low end of the inner bottom surface of the mud storage tank 1, and the drain pipe 4 connects to the drain hole 6. A filter screen 7 is installed on the inner bottom surface of the mud storage tank 1 at the position of the mud hole 5. The mud in the mud storage tank 1 is conveyed to the designated location via the mud conveying pipe 2. Inside the storage tank, the slurry is filtered through the filter screen 7 before entering the slurry conveying pipe 2, preventing large particles of sand and gravel from entering the slurry conveying pipe 2. This prevents the slurry conveying pipe 2 from conveying sand and gravel into the subsequent slurry treatment station, thus not affecting the subsequent slurry treatment operations and extending the service life of the filter press. Since the bottom surface of the slurry storage tank 1 is inclined, and the drain pipe 4 is installed at the lower end of the inclined surface, the sand and gravel filtered by the filter screen 7 moves towards the drain pipe 4 under the action of the inclined surface. The sand and gravel enter the drain pipe 4 through the drain hole 6 and are finally discharged uniformly through the drain pipe 4.
[0019] Example 2
[0020] Since the filter screen 7 may become clogged after long-term use, affecting the delivery of mud, in accordance with the first embodiment, the filter screen 7 is installed on the inner ring of the annular disc 12. The annular disc 12 is connected to the mud storage tank 1 by screws, so that the annular disc 12 can be detachably installed on the inner bottom wall of the mud storage tank 1, making it convenient to replace and clean the filter screen 7.
[0021] Example 3
[0022] Based on Example 2, such as Figure 1 and Figure 3 As shown, a manhole 13 is provided on the top of the mud storage tank 1. The manhole 13 is connected to the inner cavity of the mud storage tank 1. A ladder 14 is installed on the inner wall of the mud storage tank 1. Through the manhole 13 and the ladder 14, workers can enter the mud storage tank 1 to disassemble the filter screen 7 and install a new filter screen 7.
[0023] Furthermore, a sealing groove 15 is formed around the manhole 13 at the top of the mud storage tank 1. A counterweight plug 16 is fitted inside the sealing groove 15. An annular sealing gasket 17 is fixed on the step formed by the sealing groove 15 and the manhole 13. The counterweight plug 16 compresses the annular sealing gasket 17, causing it to deform. When the counterweight plug 16 is placed inside the sealing groove 15, it will compress the annular sealing gasket 17, causing it to deform. This will cause the annular sealing gasket 17 to adhere tightly between the counterweight plug 16 and the step, forming a high-strength sealing surface to prevent mud leakage from the mud storage tank 1. A pull ring is fixed at the top of the counterweight plug 16, making it easy to lift the counterweight plug 16 to expose the manhole 13.
[0024] Example 4
[0025] Based on Example 3, such as Figure 1 and Figure 2 As shown, a flange 8 is fixedly fitted at the bottom of the sewage pipe 4. A plug 9 is flange-connected to the flange 8. An annular sealing ring 10 is fixed on the top surface of the plug 9. An annular groove 11 is opened at the bottom of the sewage pipe 4. The axial length of the annular sealing ring 10 is greater than the axial depth of the annular groove 11. The annular sealing ring 10 is interference-fitted into the annular groove 11. The bottom opening of the sewage pipe 4 is sealed by the plug 9. The sand and gravel in the mud storage tank 1 are periodically discharged. During discharge, a trolley is set under the sewage pipe 4, the plug 9 is removed, and the sand and gravel in the mud storage tank 1 are discharged. The sand and gravel in the mud storage tank 1 are discharged into the cart through the drain pipe 4. After discharge, the plug 9 is installed at the bottom of the drain pipe 4, so that the annular sealing ring 10 fits into the annular groove 11. Since the axial length of the annular sealing ring 10 is greater than the axial depth of the annular groove 10, after the plug 9 is installed, the annular sealing ring 10 will be squeezed and interference-fitted into the annular groove 11 to form a high-strength sealing surface, which improves the sealing strength between the plug 9 and the drain pipe 4, so that the mud in the mud storage tank 1 will not overflow from the drain pipe 4.
