Description

Technical Field

[0001] This utility model relates to the field of geological logging and sand extraction technology, specifically a geological logging and sand extraction device. Background Technology

[0002] Geological logging is a wellbore exploration technology that integrates geology, electromechanical engineering, chemical analysis, and computer science. During the drilling process, it collects, organizes, and analyzes a large amount of information, establishes formation profiles while drilling, discovers and evaluates oil and gas reservoirs, and helps ensure safe drilling operations and protect oil and gas reservoirs. During the drilling process, drilling cuttings are carried to the surface by the high-speed flowing mud in the drill string. The cuttings are then filtered out by a mud vibrating screen. Due to the different sizes of the cuttings particles, they accumulate on the slope near the sand pit. Rock cuttings are usually collected manually on site. The rock cuttings that are covered with drilling mud are then washed with water, taken back to the geological room, dried, and then subjected to geological analysis. There is now a mechanical sand extractor that uses a spiral sand extractor to replace manual collection and improve collection efficiency. However, although this device can assist in sand extraction, it cannot screen the collected rock cuttings. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7In this embodiment of the utility model, a geological logging sand extractor includes a sand extraction cylinder 100 and a sand extraction head 200. A spiral conveying blade 110 is rotatably arranged inside the sand extraction cylinder 100. It also includes an installation box 300, a screening cylinder 400, a screening plate 500, and a collection box 600. A feeding hopper 120 is provided on the outer wall of the sand extraction cylinder 100 for discharging the conveyed rock cuttings. The installation box 300 is located below the feeding hopper 120, and an installation cavity is opened inside the installation box 300. Four support legs are fixedly connected to the bottom surface of the installation box 300. The screening cylinder 400 is rotatably arranged in the installation cavity of the installation box 300, and a sand inlet 410 is opened on the top surface of the screening cylinder 400. The bottom of the feeding hopper 120... The bottom surface of the screening cylinder 400 is provided with a filter screen 420 corresponding to the position of the sand inlet 410. The screening cylinder 400 is rotatably connected to a rotating mechanism 430. The outer end of the sand collection cylinder 100 is equipped with a motor 1 that drives the spiral conveying blades 110 to rotate. The outer wall of the screening cylinder 400 is equipped with a motor 2 that drives the rotating mechanism 430 to rotate. Several screening plates 500 are provided. Several screening plates 500 are installed at equal angles on the outer wall of the rotating mechanism 430. The screening plate 500 includes a rectangular frame 510 and a filter screen 520. The collection box 600 is located at the bottom of the mounting box 300 and is used to receive the fine sand filtered by the filter screen 520. The collection box 600 is equipped with a filter cloth 630 inside.

[0016] Specifically, the motor one installed at the outer end of the sand extraction cylinder 100 is started. The motor one operates and outputs power, driving the spiral conveying blades 110, which are rotated inside the sand extraction cylinder 100, to rotate. The sand extraction head 200 cooperates with the sand extraction cylinder 100 to contact the rock cuttings at the geological logging site. As the spiral conveying blades 110 rotate, the collected rock cuttings are gradually conveyed into the sand extraction cylinder 100. Finally, the rock cuttings enter the screening cylinder 400 through the feeding hopper 120. Starting the second motor can drive the rotating mechanism 430 to rotate, causing the rotating mechanism 430 to drive the screening cylinder 400. As the screening plate 500 rotates, and under the rotation of the screening plate 500 and the gravity of the rock chips themselves, fine sand with a particle size smaller than the aperture of filter screen 420 and filter screen 520 will pass through filter screen 420 and fall down, while larger rock chips will remain in the screening cylinder 400. The collection box 600, located at the bottom of the installation box 300, is used to collect the fine sand filtered by filter screen 420 and filter screen 520. The collection box 600 is equipped with a filter cloth 630. After the fine sand falls into the collection box 600, the filter cloth 630 will filter the fine sand again and filter out the residual liquid. Example 1

[0017] like Figure 3-5As shown, in this embodiment, the rotating mechanism 430 includes a rotating shaft 431. Both ends of the rotating shaft 431 are rotatably connected to the two inner walls of the screening cylinder 400. An outer sleeve 432 is fixedly fitted onto the outer wall of the rotating shaft 431. Several protrusions 4321 are provided at equal angles on the outer wall of the outer sleeve 432. Each protrusion 4321 has a mating groove 4322 on its top surface. Two C-shaped columns 433 are symmetrically fixedly connected to the top surfaces of the protrusions 4321. Each C-shaped column 433 has a snap-fit ​​groove 4331 on its top side. A mating block 550 that mates with the mating groove 4322 is fixedly connected to the bottom surface of the rectangular frame 510. Two snap fasteners 540 are provided on the outer wall of the rectangular frame 510, and these snap fasteners 540 engage with the snap-fit ​​grooves 4331. A scraper 530 is fixedly fitted onto the top surface of the rectangular frame 510, and the top of the scraper 530 contacts the inner wall of the screening cylinder 400.

[0018] In this embodiment, motor two is started, and the motor shaft of motor two is driven to the rotating shaft 431 through a coupling, causing the rotating mechanism 430 to rotate, thereby causing several screening plates 500 to rotate synchronously. During rotation, rock debris inside the screening cylinder 400 repeatedly comes into contact with filter screen two 520 and filter screen one 420, so that fine sand smaller than its pore size passes through the filter holes and enters the collection box 600 for collection. When the rotating mechanism 430 rotates, the scraper 530 scrapes the inner wall of the screening cylinder 400, reducing the adhesion of rock debris to the inner wall of the screening cylinder 400; when cleaning or... When replacing the screening plate 500, the two clips 540 on the rectangular frame 510 can be pressed down to retract the clips 540 and stop engaging with their corresponding slots 4331. At this time, the screening plate 500 can be moved upward along the inner wall of the two C-shaped columns 433. During installation, the screening plate 500 is inserted into the two symmetrical C-shaped columns 433 from top to bottom until the mating block 550 is inserted into the corresponding mating groove 4322. Then, the clips 540 engage with the slots 4331 on the C-shaped column 433, thus fixing the screening plate 500.

[0019] like Figure 6-7 As shown, in this embodiment, the collection box 600 further includes a bottom frame 610 and a box body 620. Four insertion posts 611 are symmetrically fixedly connected to the top surface of the bottom frame 610. Each of the four insertion posts 611 has a second snap fastener 612 on its sidewall. The bottom surface of the box body 620 has four symmetrically arranged insertion slots 621 that engage with the insertion posts 611. The outer wall of the box body 620 has a second snap fastener slot 622 that engages with the second snap fastener 612. The filter cloth 630 is fixed between the box body 620 and the bottom frame 610. The device also includes a base 700. A groove 710 is formed on the inner bottom surface of the base 700. A drain pipe 720 is inserted into the outer wall of the base 700. The other end of the drain pipe 720 communicates with the interior of the groove 710. The interior of the base 700 is used to house the collection box 600.

[0020] In practice, the sieved fine sand falls into the collection box 600, specifically into the upper box 620, and accumulates on the surface of the filter cloth 630. The mud and water will be filtered out along the filter cloth 630 and flow into the groove 710 below, and finally discharged through the drain pipe 720, so that the fine sand in the collection box 600 can be initially dried. When it is necessary to remove the fine sand, the second buckle 612 can be pressed to retract the second buckle 612 into the insertion post 611, and no longer engage with the second buckle groove 622. At this time, the box 620 can be separated from the bottom frame 610, so that the filter cloth 630 along with the fine sand on its surface can be removed. Finally, a new filter cloth 630 is taken out and laid on the top surface of the bottom frame 610, and then the box 620 and the bottom frame 610 are snapped and fixed to prepare for the next reception. Example 2

[0021] Based on Example 1, in order to facilitate the discharge of large rock fragments remaining inside the screening cylinder 400.

[0022] like Figure 1-2 As shown, in this embodiment, the front sidewall of the mounting box 300 has two symmetrically arranged sliding slots 310, and the front sidewall of the mounting box 300 is provided with two limiting plates 320. Each of the two limiting plates 320 has a limiting groove 322 on its opposite end. The rear sidewall of each of the two limiting plates 320 is fixedly connected with a connecting rod 321, which slides into the interior of each of the two sliding slots 310. The outer wall of each of the two limiting plates 320 is fitted with a return spring 330. The bottom surfaces of the two limiting plates 320 are fixedly connected by a connecting rod 340, which causes the two limiting plates 320 to move synchronously. The front sidewall of the screening cylinder 400 is fixedly connected with a connecting shaft 440, and the end of the connecting shaft 440 is fixedly connected with a connecting plate 450. The size of the connecting plate 450 matches the size of the limiting groove 322, and the outer wall of the connecting plate 450 is fixedly connected with a handle 460.

[0023] In practice, under the elastic force of the return spring 330, the limiting plate 320 will extend outward by default, aligning with the position of the connecting plate 450. When the sand inlet 410 faces upward, the connecting plate 450 faces the left limiting plate 320, and the limiting groove 322 of the left limiting plate 320 is engaged with the outer wall of the connecting plate 450, restricting the rotation of the screening cylinder 400. When only large rock fragments remain inside the screening cylinder 400, a new box is placed under the mounting box 300, and the connecting rod 340 is pressed towards the mounting box 300, causing the two limiting plates 320 to abut against the surface of the mounting box 300, no longer touching the connecting plate 450. Engage the connection. At this point, hold the handle 460 and rotate it 180 degrees around the axis of the connecting shaft 440, so that the end of the connecting plate 450 faces the right-side limiting plate 320. At this time, the screening cylinder 400 is fixed to the connecting shaft 440, causing the sand inlet 410 to flip downwards. Large rock fragments inside will fall into the box naturally due to gravity. At this time, release the pressure on the handle 460, and the return spring 330 will drive the limiting plate 320 to rebound, so that the limiting groove 322 on the right-side limiting plate 320 engages with the connecting plate 450. Then, start the motor 2 to drive the rotating mechanism 430 to rotate, so that the screening plate 500 assists in sweeping out the large rock fragments in the screening cylinder 400.
