[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] During oil and gas exploration drilling, cuttings logging data is crucial for understanding subsurface lithology, oil-bearing properties, and stratigraphic correlation. After retrieval, the cuttings are mixed with drilling fluid, necessitating thorough cleaning before subsequent analysis. However, current drilling site equipment for cuttings cleaning and separation is often limited in function, typically offering only one method and failing to provide multiple options to meet specific site requirements.

[0019] Example 1 like Figures 1-3 As shown, in order to solve the above-mentioned technical problems, this utility model provides a logging cuttings retrieval and washing device, including a feeding assembly 10, a vibrating retrieval and washing section 20, and an integrated retrieval and washing section 30; the feeding assembly 10 is configured to transport a cuttings mixture and includes a feeding port 110; the vibrating retrieval and washing section 20 is disposed below the feeding port 110; the vibrating retrieval and washing section 20 includes a vibrating screen 210 to vibrate and separate the cuttings mixture output from the feeding port 110; the integrated retrieval and washing section 30 is disposed below the feeding port 110 and arranged side by side with the vibrating retrieval and washing section 20; the integrated retrieval and washing section 30 includes a separation box 310, a cleaning assembly 320 disposed in the separation box 310, and a drying assembly 330 to clean, dry, and separate the cuttings mixture output from the feeding port 110.

[0020] As can be seen from the above, by setting up the vibration washing unit 20 and the integrated washing unit 30 respectively, two different methods for cleaning and separating rock cuttings mixtures are provided. Users can choose according to the actual needs on site, greatly improving flexibility and practicality. When the requirements for cleaning and separating the rock cuttings mixture are high, the staff can choose the integrated washing unit 30 to clean and separate the rock cuttings mixture. When the requirements for cleaning and separating the rock cuttings mixture are low, the staff can choose the vibration washing unit 20 to clean and separate the rock cuttings mixture. The vibration washing unit 20 disperses the rock cuttings mixture by vibrating the vibrating screen 210, and then uses the vibrating screen 210 to screen the dispersed rock cuttings mixture to separate rock cuttings and sludge. The integrated washing unit 30 cleans and separates the rock cuttings mixture through the cleaning component 320 and the separation box 310, quickly cleaning the sludge off the rock cuttings mixture. The drying component 330 dries the separated rock cuttings. The cleaning and separation effect is good, effectively separating rock cuttings and sludge, and ensuring the purity of the rock cuttings sample.

[0021] It should be noted that the rock debris mixture includes sludge clumps and rock debris.

[0022] It should also be noted that the feeding assembly 10 includes a feeding bracket and a feeding tube disposed on the feeding bracket, and the feeding port 110 is disposed at one end of the feeding tube.

[0023] It should also be noted that, such as Figure 1 As shown, the logging cuttings washing device also includes a first sand-containing box 220 and a second sand-containing box 230; the first sand-containing box 220 is located at one end of the vibrating screen 210, and the second sand-containing box 230 is located directly below the vibrating screen 210; and the vibrating screen 210 is provided with multiple screen holes, the diameter of which is smaller than the diameter of the cuttings and larger than the diameter of the sludge clumps, so that the cuttings separated by vibration fall into the first sand-containing box 220 through the screen holes.

[0024] It should also be noted that the vibrating washing section 20 is a linear vibrating screen. The vibrating screen 210 uses a vibrating motor as the vibration source, which causes the rock cutting mixture to be thrown up on the screen and move forward in a straight line. The vibrating screen 210 produces oversize and undersize materials. The oversize material (rock cuttings) moves to the first sand receiving box 220, and the undersize material (sludge clumps) is collected through the second sand receiving box 230. In addition, the specific structure and working principle of the vibrating washing section 20 are existing technologies and will not be described in detail in this application.

[0025] Example 2 like Figures 1-3As shown, the logging cuttings retrieval device includes a feeding assembly 10, a vibrating retrieval section 20, and an integrated retrieval section 30. The feeding assembly 10 is configured to transport a cuttings mixture and includes a feeding port 110. The vibrating retrieval section 20 is located below the feeding port 110 and includes a vibrating screen 210 to vibrate and separate the cuttings mixture output from the feeding port 110. The integrated retrieval section 30 is located below the feeding port 110 and is arranged side by side with the vibrating retrieval section 20. The integrated retrieval section 30 includes a separation box 310, a cleaning assembly 320, and a drying assembly 330 located within the separation box 310 to clean, dry, and separate the cuttings mixture output from the feeding port 110.

[0026] As can be seen from the above, by setting up the vibration washing unit 20 and the integrated washing unit 30 respectively, two different methods for cleaning and separating rock cuttings mixtures are provided. Users can choose according to the actual needs on site, greatly improving flexibility and practicality. When the requirements for cleaning and separating the rock cuttings mixture are high, the staff can choose the integrated washing unit 30 to clean and separate the rock cuttings mixture. When the requirements for cleaning and separating the rock cuttings mixture are low, the staff can choose the vibration washing unit 20 to clean and separate the rock cuttings mixture. The vibration washing unit 20 disperses the rock cuttings mixture by vibrating the vibrating screen 210, and then uses the vibrating screen 210 to screen the dispersed rock cuttings mixture to separate rock cuttings and sludge. The integrated washing unit 30 cleans and separates the rock cuttings mixture through the cleaning component 320 and the separation box 310, quickly cleaning the sludge off the rock cuttings mixture. The drying component 330 dries the separated rock cuttings. The cleaning and separation effect is good, effectively separating rock cuttings and sludge, and ensuring the purity of the rock cuttings sample.

[0027] It should be noted that the rock debris mixture includes sludge clumps and rock debris.

[0028] It should also be noted that the feeding assembly 10 includes a feeding bracket and a feeding tube disposed on the feeding bracket, and the feeding port 110 is disposed at one end of the feeding tube.

[0029] It should also be noted that, such as Figure 1 As shown, the logging cuttings washing device also includes a first sand-containing box 220 and a second sand-containing box 230; the first sand-containing box 220 is located at one end of the vibrating screen 210, and the second sand-containing box 230 is located directly below the vibrating screen 210; and the vibrating screen 210 is provided with multiple screen holes, the diameter of which is smaller than the diameter of the cuttings and larger than the diameter of the sludge clumps, so that the cuttings separated by vibration fall into the first sand-containing box 220 through the screen holes.

[0030] It should also be noted that the vibrating washing section 20 is a linear vibrating screen. The vibrating screen 210 uses a vibrating motor as the vibration source, which causes the rock cutting mixture to be thrown up on the screen and move forward in a straight line. The vibrating screen 210 produces oversize and undersize materials. The oversize material (rock cuttings) moves to the first sand receiving box 220, and the undersize material (sludge clumps) is collected through the second sand receiving box 230. In addition, the specific structure and working principle of the vibrating washing section 20 are existing technologies and will not be described in detail in this application.

[0031] like Figure 1 , Figure 2 As shown, in some embodiments, the integrated washing unit 30 further includes a support member 340, a circumferential drive assembly 350, and a radial drive assembly 360; the support member 340 is used to receive the separated material after the rock cuttings mixture is separated by the separation box 310; the circumferential drive assembly 350 is disposed on the support member 340; the radial drive assembly 360 is disposed on the circumferential drive assembly 350, and the separation box 310 is disposed on the radial drive assembly 360; wherein, the circumferential drive assembly 350 is configured to drive the separation box 310 to rotate around the support member 340, and the radial drive assembly 360 is configured to drive the separation box 310 to move in the radial direction of the support member 340, so that the separation box 310 is aligned with the feed port 110 and receives the rock cuttings mixture.

[0032] The circumferential drive assembly 350 rotates the separation box 310, reducing the angle between the separation box 310 and the feed port 110. The radial drive assembly 360 moves the separation box 310 radially, reducing the distance between the separation box 310 and the feed port 110, thus aligning the separation box 310 with the feed port 110 and enabling it to collect the rock chip mixture. The support member 340 not only provides a structural foundation for the circumferential drive assembly 350 and the radial drive assembly 360, but also collects the separated material from the separation box 310.

[0033] like Figure 2 As shown, in some embodiments, the circumferential drive assembly 350 includes a turntable 3501 and a circumferential drive member; the turntable 3501 is rotatably disposed on the support member 340; the circumferential drive member is disposed on the support member 340, and the rotation axis of the circumferential drive member is connected to the turntable 3501 to drive the turntable 3501 to rotate.

[0034] It should be noted that the turntable 3501 is, but is not limited to, rotatably mounted on the support 340 via rolling bearings; the circumferential drive component is, but is not limited to, a servo motor.

[0035] It should also be noted that a central water pipe is installed on the top of the turntable 3501, and multiple third spray nozzles are installed on the central water pipe to wash the turntable 3501 and the support 340 to prevent the accumulation of sludge, rock debris and other contaminants.

[0036] like Figure 2 As shown, in some embodiments, the radial drive assembly 360 includes multiple support seats, multiple radial drive members, and multiple radial actuators 3601; the multiple support seats are rotatably disposed on the turntable 3501, and the multiple support seats are arranged circumferentially around the turntable 3501; the multiple radial drive members are disposed within the turntable 3501, and each of the multiple radial drive members corresponds to one of the multiple support seats, with the rotation axis of the radial drive member connected to the corresponding support seat; the multiple radial actuators 3601 correspond to one of the multiple support seats, and the radial actuators 3601 are disposed on the corresponding support seats, with the separation box 310 disposed on the telescopic rod of the radial actuator 3601.

[0037] The extension and retraction of the radial actuator 3601 drives the separation box 310 to move in the radial direction of the support 340, bringing the separation box 310 closer to the feed port 110, ensuring that the feed port 110 can convey the rock chip mixture into the separation box 310; the radial drive drives the separation box 310 to rotate, enabling the separation box 310 to flip, ensuring that after cleaning, drying and separation, the separation box 310 can transfer the separated material onto the support 340.

[0038] It should be noted that the support base is not limited to being rotatably mounted on the turntable 3501 via rolling bearings; the radial drive component is not limited to a servo motor, and the radial actuator 3601 is not limited to an electric push rod.

[0039] It should also be noted that there are multiple separation boxes 310, and each separation box 310 corresponds to a different radial actuator 3601. The separation box 310 is mounted on the telescopic rod of the corresponding radial actuator 3601 by a fixing rod.

[0040] It should also be noted that after the rock cuttings mixture is injected into the separation box 310, it is washed by water injection in the cleaning component 320. The first separated material is sludge, which falls onto the support component 340. After the cleaning and drying are completed, the separation box 310 is flipped over, transferring the separated rock cuttings onto the support component 340.

[0041] like Figures 2-4 As shown, in some embodiments, the cleaning assembly 320 includes multiple cleaning pipes, multiple first spray nozzles 3201, and a vibrator 3202; the multiple cleaning pipes are disposed on the separation box 310; the multiple first spray nozzles 3201 are disposed on the cleaning pipes and arranged at intervals along the cleaning pipes; the vibrator 3202 is disposed at the bottom of the separation box 310.

[0042] Clean water is injected into the separation box 310 through the cleaning pipe and the first spray nozzle 3201. The clean water washes the rock debris mixture, which serves as a primary cleaning action. The dried rock debris in the separation box 310 is vibrated and dispersed by the vibrator 3202, which further screens out the residual sludge in the rock debris and improves the cleaning effect.

[0043] It should be noted that the vibrator 3202 at the bottom of the separation box 310 operates after the cleaning component 320 and the drying component 330 have completed the first cleaning process, thus playing a secondary cleaning role.

[0044] It should also be noted that the drying assembly 330 includes multiple dryers disposed on the inner wall of the drying chamber.

[0045] In some embodiments, the bottom of the separation chamber 310 is provided with a plurality of filter holes.

[0046] The sludge cleaned by the cleaning component 320 is filtered out through the filter holes, while the rock debris is retained.

[0047] It should be noted that, as Figure 3 As shown, the integrated washing unit 30 also includes an agitator 391 and an agitator motor. The agitator 391 is located inside the separation box 310 and is rotatably disposed at the bottom of the separation box 310. The agitator motor is disposed at the bottom of the separation box 310, and the rotating shaft of the agitator motor is connected to the agitator shaft, thereby driving the agitator 391 to rotate, thereby improving work efficiency during washing and drying.

[0048] like Figure 2 As shown, in some embodiments, the support member 340 includes a first guide section 3401 and a second guide section 3402 connected to the first guide section 3401. The second guide section 3402 is provided with a discharge port 3403 at one end away from the first guide section 3401, and the width of the second guide section 3402 gradually decreases along the length direction.

[0049] The separated material is guided to the conveying assembly 370 by setting the first guide section 3401 and the second guide section 3402.

[0050] It should be noted that, as Figure 2 As shown, the support member 340 includes a support plate and a guide plate disposed on the support plate, thereby forming a first guide section 3401 and a second guide section 3402; in addition, a cleaning pipe is disposed on the guide plate, and a plurality of fourth spray nozzles 3404 are disposed on the cleaning pipe to rinse the support member 340 and prevent the accumulation of rock debris and sludge.

[0051] It should be noted that the support member 340 is arranged at an angle downwards, and there is an angle between the support member 340 and the conveying assembly 370, so as to smoothly guide the rock cuttings onto the conveying assembly 370.

[0052] It should also be noted that, such as Figure 2 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction.

[0053] like Figure 1 As shown, in some embodiments, the integrated washing unit 30 further includes a conveying assembly 370 and a filter element; the conveying assembly 370 is disposed at the discharge port 3403 and located below the support member 340; the transition member 380 is disposed at one end of the conveying assembly 370 away from the discharge port 3403 to receive the separated material on the conveying assembly 370.

[0054] It should be noted that baffles are provided on both sides of the conveying assembly 370 to prevent the transported materials from falling off; the conveying assembly 370 includes, but is not limited to, a belt conveyor, and the specific structure of the conveying assembly 370 is prior art, which will not be described in detail in this application.

[0055] It should also be noted that a spray pipe can be installed on the baffle, and multiple fifth spray nozzles are installed on the spray pipe to rinse the conveying component 370 and prevent the accumulation of rock chips, sludge and other residues.

[0056] like Figure 5 , Figure 6 As shown, in some embodiments, the transition member 380 includes a first transition housing 3801, a second transition housing 3802, a sand conveying pipe 3803, a plurality of cleaning pipes, and a plurality of second spray nozzles 3804; the second transition housing 3802 is disposed at the bottom of the first transition housing 3801 and communicates with the first transition housing 3801, and the cross-sectional width of the second transition housing 3802 gradually decreases in the height direction; the sand conveying pipe 3803 is disposed at the bottom of the second transition housing 3802 and communicates with the second transition housing 3802; the plurality of cleaning pipes are disposed at the bottom of the second transition housing 3802; and the plurality of second spray nozzles 3804 are disposed on the cleaning pipes and arranged at intervals along the cleaning pipes.

[0057] The material separated from the conveying assembly 370 is received by the transition piece 380. The second transition shell 3802, whose cross-sectional width gradually decreases, acts as a confluence. The bottom of the second transition shell 3802 is flushed by the cleaning pipe and the second spray nozzle 3804, so that the rock debris and sludge are flushed into the sand conveying pipe 3803 to avoid the accumulation of rock debris and sludge.

[0058] It should be noted that the first transition shell 3801 is cubic, and the second transition shell 3802 is frustum-shaped, with the second transition shell 3802 being larger at the top and smaller at the bottom. In some embodiments, the integrated washing unit 30 further includes a sand catcher located below the transition member 380.

[0059] It should be noted that, as Figure 7As shown, the sand collector includes a base 3901, a fixed plate 3902, and multiple rock cuttings collection boxes 3903. The fixed plate 3902 is rotatably mounted on the base 3901. The multiple rock cuttings collection boxes 3903 are arranged at equal intervals around the fixed plate 3902, and the bottom of the rock cuttings collection box is provided with a drainage hole. One of the rock cuttings collection boxes 3903 is located directly below the sand conveying pipe 3803 and collects the rock cuttings output by the sand conveying pipe 3803. When the rock cuttings collection box 3903 is full of rock cuttings, the fixed plate 3902 can be rotated to align another rock cuttings collection box 3903 with the sand conveying pipe 3803.

[0060] It should also be noted that when the transition piece 380 receives sludge, a sludge receiving box is placed at the bottom of the sand conveying pipe 3803; when the transition piece 380 receives rock cuttings, a sand receiving device is placed at the bottom of the sand conveying pipe 3803.

[0061] During operation, staff can choose to use the integrated washing unit 30 or the vibrating washing unit 20 to collect rock cuttings as needed. When the vibrating washing unit 20 is selected, the vibrating washing unit 20 disperses the rock cutting mixture by vibrating the vibrating screen 210. The vibrating screen 210 produces oversize and undersize materials. The oversize material (rock cuttings) moves to the first sand collection box 220, and the undersize material (impurities, sludge clumps, etc.) is collected through the second sand collection box 230. Of course, the staff can put the rock cuttings separated by the vibrating washing unit 20 into the integrated washing unit 30 for cleaning and drying as needed. When the integrated washing unit 30 is selected, the circumferential drive assembly 350 drives the turntable 3501 to rotate, and the radial actuator 3601 drives the corresponding separation box 310 to move towards the feed port 110, so that the separation box 310 is aligned with the feed port 110 to inject the rock cuttings mixture into the separation box 310; the washing assembly 320 washes the rock cuttings mixture, and at the same time the agitator 391 rotates to improve the washing effect. The washed sludge flows out through the filter holes, and the rock cuttings are retained in the separation box 310, thus achieving primary cleaning; then the drying assembly 330 dries the rock cuttings, and the vibrator 3202 at the bottom of the separation box 310 vibrates the dried rock cuttings to further remove the residual sludge in the rock cuttings, completing secondary cleaning; the radial drive assembly drives the separation box 310 to rotate, transferring the rock cuttings in the separation box 310 to the support 340, and then to the conveying assembly 370, which transports them into the sand receiving device.

[0062] Although the present invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
