[0002] Oil drilling engineering is an important part of oil exploration and development. Its main purpose is to use specific oil drilling equipment to drill through multiple formations along the designed track from the ground until it reaches the predetermined oil and gas layer or possible oil and gas layer, forming a stable oil and gas well for oil and gas production or injection of required fluids;

[0003] Among them, drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. Drilling fluid plays multiple roles in the drilling process, such as lubrication, cooling the drill bit, and carrying rock cuttings. If the drilling fluid contains a large amount of sand or other solid particles, its performance will be significantly reduced, such as reducing the lubrication effect, increasing pumping resistance, and affecting the sand carrying capacity. At the same time, if the sand and other solid particles in the drilling fluid are directly discharged into the environment without treatment, it will cause pollution to the environment, so the drilling fluid needs to be desanded.

[0004] Chinese patent document CN208473743U discloses a drilling fluid desilting and desanding device, comprising a first box body, the upper part of the first box body is hollow, a desander and a desilter are fixedly installed on the top surface of the first box body, the lower part of the desander and the lower part of the desilter are both located inside the first box body, a through hole is opened on the right side of the upper part of the first box body, a funnel is fixedly installed in the first box body, the funnel is located above the through hole, the sand outlet of the desander and the mud outlet of the desilter are both located above the funnel, a baffle is fixedly installed on the left side of the bottom of the funnel, and the front and rear sides of the baffle are fixedly connected to the inner wall of the first box body.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 and Figure 2 As shown, a drilling fluid desanding device for oil drilling engineering comprises a base 1, a slide rail 2 is fixedly connected to the upper end of the base 1, a vibration component 3 is slidably connected to the upper end of the slide rail 2, a support 4 is provided on the front side of the base 1, a motor 5 is fixedly connected to the upper end of the support 4, a connecting block 6 is fixedly connected to the upper end of the vibration component 3, a box body 7 with an internal hollow opening at the upper end is fixedly connected to the upper end of the connecting block 6, a filter component 8 is rotatably connected to the inner cavity of the box body 7, a transmission component 9 is fixedly connected to the rear end of the filter component 8, two partitions 10 are fixedly connected to the inner wall of the box body 7, sliding components 11 are slidably connected to the two sides of the box body 7, a liquid outlet 12 is opened on the lower side of the box body 7, and a material outlet 13 is opened on the side wall of the box body 7;

[0027] In actual use, the vibration component 3 vibrates the box 7, driving the filter component 8 in the box 7 to vibrate, thereby separating the sand-containing drilling fluid into solid and liquid. Through high-frequency vibration, the solid particles jump and roll on the surface of the filter component 8, while the liquid flows out through the filter component 8, thereby achieving solid-liquid separation.

[0028] like Figure 3As shown, the vibration assembly 3 includes a slider 302 slidably connected to the upper end of the slide rail 2. If the upper end of the slider 302 is fixedly connected to the frame 301, when the vibration assembly 3 is running, the slider 302 slidably connected to the slide rail 2 can make the frame 301 only shake in the horizontal direction along the slide rail 2. The shaking in the horizontal direction mainly provides kinetic energy for the lateral movement of the material, which helps the material to be evenly distributed on the screen and promotes the sliding of the material on the screen surface, which helps smaller particles of material to pass through the screen, while larger particles of material remain on the screen surface, avoiding shaking of the frame 301 in other directions during vibration, uneven distribution of materials on the screen, and affecting the screening efficiency.

[0029] The frame 301 and the base 1 are slidably connected with a slide bar 303, which passes through the base 1 and the frame 301 from left to right in sequence. A spring 304 is sleeved on the outer surface of the slide bar 303, one end of the spring 304 is fixedly connected to the inner wall of the base 1, and the other end is fixedly connected to the outer wall of the frame 301 on the opposite side of the base 1. A fixed block 310 is fixedly connected to the middle of the inner cavity of the frame 301, and a slide groove 311 is opened in the middle of the fixed block 310. A rotating shaft 308 is provided on the left and right sides of the slide groove 311. The front and rear sides of the two rotating shafts 308 are fixedly connected to eccentric wheels 307. The front ends of the two rotating shafts 308 are fixedly connected to pulleys 1 305, and the outer surfaces of the two pulleys 1 305 are commonly connected to belts 1 306 for transmission.

[0030] When the moving wheel of the eccentric wheel rotates on the center wheel, since the axis of the moving wheel is not on the axis of the center wheel, a certain eccentricity will be generated. This eccentricity causes the moving wheel to generate centrifugal force while rotating. The magnitude of the centrifugal force is related to the eccentricity and the rotation speed of the moving wheel. Generally, the larger the eccentricity and the higher the rotation speed, the greater the centrifugal force generated. When the centrifugal force generated by the eccentric wheel acts on the equipment or mechanism, it can cause the equipment or mechanism to vibrate. This vibration can be a composite vibration in the vertical and horizontal directions, which can not only evenly disperse the materials on the screen surface, but also avoid the shaking of the screen box. In the vertical direction, the centrifugal force causes the screen box to vibrate greatly, causing the materials on the screen surface to jump quickly, effectively removing large particles.

[0031] The lower ends of the front and rear sides of the two rotating shafts 308 are fixedly connected to the second support 309 , and the second support 309 plays a role in fixing the rotating shafts 308 .

[0032] like Figure 4As shown, the filter assembly 8 includes four transmission rollers 805 distributed in a rectangular array and rotatably connected to the inner wall of the box body 7. The rear ends of the four transmission rollers 805 all penetrate the rear side wall of the box body 7. The two transmission rollers 805 located on the upper side are commonly connected to the transmission belt 1 801 through transmission, and the two transmission rollers 805 located on the lower side are commonly connected to the transmission belt 2 802 through transmission. The transmission belt 1 801 is provided with a plurality of filter holes 1 803 distributed in a rectangular array, and the transmission belt 2 802 is provided with a plurality of filter holes 2 804 distributed in a rectangular array. The diameter of the filter hole 1 803 is greater than the diameter of the filter hole 2 804.

[0033] The multi-layer conveyor belt with filter holes can remove sand from the drilling fluid multiple times, and the sand removal efficiency is higher. When the sand-containing drilling fluid is poured onto the conveyor belt 1 801, the large-diameter sand particles remain on the surface of the conveyor belt 1 801, and the liquid and the small-diameter sand particles pass through the filter hole 1 803 and fall to the surface of the conveyor belt 2 802. The filter hole 2 804 on the conveyor belt 2 802 will perform a finer screening of the solid and the liquid. The sand particles will be transported to the discharge port 13 by the conveyor belt 2 802, and the drilling fluid will pass through the filter hole 2 804 and fall to the bottom wall of the box 7. After the sand removal is completed, the operator can collect the drilling fluid through the liquid outlet 12.

[0034] like Figure 4 As shown, the transmission assembly 9 includes a support three 903 fixedly connected to the rear end of the box body 7, the upper end of the support three 903 is fixedly connected to a motor two 904, the output end of the motor two 904 is fixedly connected to the rear end of the transmission roller 805 located on the lower right side, the rear sides of the four transmission rollers 805 are fixedly connected to pulley two 901, the two pulleys two 901 located on the same horizontal plane are jointly connected to the belt two 902, the pulley two 901 fixedly connected to the output end of the motor two 904 and the pulley two 901 on the same vertical plane are jointly connected to the belt two 902, and the transmission assembly 9 is used to control the operation of the transmission belt one 801 and the transmission belt two 802.

[0035] like Figure 2 As shown, two partitions 10 are respectively arranged on the left and right sides of the conveyor belt 1 801, and both partitions 10 are provided with holes 1001. The lower ends of the four holes 1001 are respectively flush with the lower ends of the conveyor belt 1 801 and the conveyor belt 2 802, and the two partitions 10 are fixedly connected with discharge plates 1002 on the opposite sides of the inner wall of the box body 7. One end of the four discharge plates 1002 is arranged on the lower side of the four holes 1001, and the other end is arranged on the lower side of the discharge port 13. The left and right ends of the box body 7 are provided with discharge ports 13 corresponding to the positions of the four holes 1001, and the heights of the four discharge ports 13 in the vertical direction are all lower than the four holes 1001 opposite thereto. The sand particles sieved by the conveyor belt 1 801 and the conveyor belt 2 802 are transported to the holes 1001, and slide to the discharge port 13 through the discharge plate 1002. The operator can collect the sand particles and then further process them.

[0036] like Figure 5 As shown, the sliding assembly 11 includes two sliding frames 1101 slidably connected to the box body 7, and the horizontal parts of the two sliding frames 1101 are slidably connected with scrapers 1102. The lower ends of the two scrapers 1102 are respectively connected to the upper ends of the conveyor belt 1 801 and the conveyor belt 2 802. The scrapers 1102 can scrape off the particles deposited on the conveyor belt 1 801 and the conveyor belt 2 802 to avoid clogging of the filter holes and affect the sand removal efficiency.

[0037] It should be noted that the specific installation method, circuit connection method and control method of the motor 1 5 and the motor 2 904 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0038] The working principle of the utility model is as follows: first, start the motor 5, the motor 5 drives the vibration component 3 to vibrate, and the box 7 starts to shake horizontally on the slide rail 2 under the action of the vibration component 3, and then start the motor 2 904, the conveyor belt 1 801 and the conveyor belt 2 802 start to drive, and the drilling fluid to be desanded is poured from the upper side of the conveyor belt 1 801 into the box 7. After the drilling fluid with sand particles falls on the conveyor belt 1 801, the drilling fluid falls downward through the filter hole 1 803, and the sand particles remain on the conveyor belt 1 801 and are transported to the discharge plate 1002, and then through the discharge plate 1002. The drilling fluid is discharged through the outlet 13, and some sand particles with small diameters will pass through the filter hole 1 803 and fall onto the conveyor belt 2 802, and then be transported by the conveyor belt 2 802 to the discharge plate 1002 and discharged through the discharge port 13. The drilling fluid will pass through the filter hole 2 804 and fall into the bottom wall of the box body 7. Under the action of the vibration component 3, the sliding frame 1101 will also move in the horizontal direction, driving the scraper 1102 to scrape off the mud and sand deposited on the conveyor belts 1 801 and 802 to avoid clogging of the filter holes. After the drilling fluid is desanded, the operator can collect the desanded drilling fluid through the discharge port 13.
