Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Currently, during drilling, it is necessary to analyze the drilling cuttings to obtain the geological conditions of the drilling area. In existing technology, the cuttings are carried out of the wellbore along with the drilling mud. A separation mechanism then separates the cuttings from the mud, and a collection cylinder 160 collects them. The collected cuttings are manually removed from the collection cylinder 160 for packaging and transportation, and then sequentially transported to a cleaning unit and an analysis unit for analysis. This process is labor-intensive and inefficient.

[0033] In view of this, the designers have designed an automated rock cuttings analysis and collection device for the logging industry. After the rock cuttings are separated from the mud, they can be collected by the rock cuttings collection mechanism 100, and then transported to the rock cuttings analysis mechanism for analysis in an automated manner. The whole process is highly automated, with low labor intensity and high efficiency.

[0034] Please combine Figure 1 and Figure 2In this embodiment, the automated cuttings analysis and acquisition device for the logging industry includes a cuttings collection mechanism 100, a cuttings conveying mechanism 200, and a cuttings analysis mechanism (not shown). The cuttings collection mechanism 100 is used to receive cuttings separated from the mud and convey them to the cuttings conveying mechanism 200. The cuttings conveying mechanism 200 is used to receive cuttings output from the cuttings collection mechanism 100 and convey them to the cuttings analysis mechanism.

[0035] The working principle of the automated cuttings analysis and acquisition device for the logging industry provided in this embodiment is as follows:

[0036] During operation, in conjunction with the solid-liquid separation device of the drilling system, the rock cuttings and mud generated during drilling are carried out of the well body together. After passing through the solid-liquid separation device, the rock cuttings fall into the rock cuttings collection mechanism 100. The rock cuttings collection mechanism 100 transports the collected rock cuttings to the rock cuttings conveying mechanism 200, and the rock cuttings conveying mechanism 200 then transports the rock cuttings to the rock cuttings analysis mechanism. In this way, the rock cuttings analysis and collection process is fully automated, reducing the manual intervention links, with a high degree of automation and high efficiency.

[0037] Please combine Figure 2In this embodiment, optionally, the rock cuttings collection mechanism 100 includes a base 110, a first motor 120, a first gimbal 130, a second motor 140, a second gimbal 150, and a collection cylinder 160. The number of second motors 140, second gimbals 150, and collection cylinders 160 are equal and correspond one-to-one. The number of each of the second motors 140, second gimbals 150, and collection cylinders 160 can be one or more. For example, in this embodiment, the number of each of the second motors 140, second gimbals 150, and collection cylinders 160 is four. The base 110 is a metal frame, which can be made by welding metal profiles. The base 110 is positioned on the rock or soil or other supports. The first motor 120 is fixed to the top of the base 110 by bolts, and the output shaft of the first motor 120 extends vertically. The first gimbal 130 is connected to the output shaft of the first motor 120, and the first gimbal 130 can rotate around the axis of the first motor 120 under the drive of the first motor 120. Four second motors 140 are fixed to the second gimbals 150, and are evenly spaced around the output shaft of the first motor 120. The output shaft of each second motor 140 extends horizontally, and adjacent second motors 140 are vertically aligned around the output shaft of the first motor 120. Each second gimbal 150 is mounted on the output shaft of a corresponding second motor 140 and can rotate under the drive of that motor. Each second gimbal 150 has a collection cylinder 160, with one end open and the other closed. When the second motor 140 is started, it can switch the open end of the collection cylinder 160 between an upward and downward position. When the open end of the collection cylinder 160 is upward, it can collect rock fragments separated from the solid-liquid separation device. Furthermore, after the rock cuttings collection is completed, the first motor 120 first drives the first gimbal 130 to rotate, causing the collecting cylinder 160, which has completed rock cuttings collection, to move away from the rock cuttings collection position, that is, away from the rock cuttings outlet position of the solid-liquid separation device. The collecting cylinder 160 then rotates to a position corresponding to the rock cuttings conveying mechanism 200. Then, the second motor 140 starts, driving the collecting cylinder 160 to rotate again, so that the open end of the collecting cylinder 160 faces the direction of gravity, allowing the rock cuttings inside to enter the rock cuttings conveying mechanism 200. Through the continuous operation of the four collecting cylinders 160, continuous receiving and transfer of rock cuttings can be achieved, resulting in flexible operation and high efficiency.

[0038] It should be noted that the rotation frequency of the first motor 120 can be matched with the drilling speed, thereby better receiving rock cuttings and improving the accuracy of subsequent rock cuttings analysis results.

[0039] Furthermore, in other embodiments, the angle of the output shaft of the adjacent second motor 140 may not be 90°, but may be any other non-zero angle other than 90°.

[0040] Please combine Figure 1 and Figure 2 In this embodiment, optionally, the cuttings conveying mechanism 200 includes a conveyor frame 210, a conveyor belt assembly 220, a collection frame 230, a conveyor tray 240, a lifting assembly 250, and an adjusting assembly 260. The conveyor frame 210 and the collection frame 230 are arranged at intervals in the conveying direction of the conveyor belt assembly 220, for example, the conveyor frame 210 and the collection frame 230 are located at opposite ends of the conveyor belt assembly 220. The conveyor frame 210 is used to receive a plurality of stacked conveyor trays 240, and each conveyor tray 240 has an outwardly folded annular flange 241 at its edge. The lowermost conveyor tray 240 among the plurality of stacked conveyor trays 240 on the conveyor frame 210 can be placed on the conveyor belt assembly 220, thereby transporting the conveyor tray 240 toward the collection frame 230 via the conveyor belt assembly 220. During the conveying process of the conveyor plate 240 by the conveyor belt assembly 220, the conveyor plate 240 can receive rock cuttings falling from the open end of the collection cylinder 160, thereby completing the transfer of rock cuttings. Furthermore, the conveyor plate 240 containing rock cuttings can move to the collection frame 230, and multiple conveyor plates 240 are stacked sequentially from bottom to top, arranged in a layered manner and positioned by the collection frame 230. During the conveying process of the conveyor plate 240 by the conveyor belt assembly 220, the lifting component and the adjusting component 260 work together to move the conveyor plate 240 relative to the conveyor belt assembly 220, causing it to move away from the conveyor belt assembly 220 first. This ensures that when receiving rock cuttings falling from the collection cylinder 160, the plate remains relatively stationary with respect to the collection cylinder 160, improving the safety of rock cuttings collection [A1], and preventing misalignment between the collection cylinder 160 and the conveyor plate 240, which could result in the rock cuttings not being completely received by the conveyor plate 240. Simultaneously, during the collection process, the lifting component 250 and the adjusting component 260 work together to lift the conveyor tray 240 away from the conveyor belt assembly 220, preventing the conveyor tray 240 from affecting the operation of the conveyor belt assembly 220 when receiving rock cuttings. This is because the continuous influx of rock cuttings into the conveyor tray 240 causes constant changes in its weight. If the conveyor tray 240 remains continuously on the conveyor belt assembly 220, it will cause increased vibration, affecting the stability of the conveyor belt assembly 220 and consequently impacting the transport of the remaining conveyor trays 240 on the conveyor belt assembly 220. After the lifted conveyor tray 240 has finished collecting rock cuttings, the lifting component 250 and the adjusting component 260 work together to place the collected conveyor tray 240 back onto the conveyor belt assembly 220, thereby transporting the conveyor tray 240 towards the collection frame 230 via the conveyor belt assembly 220.

[0041] Please combine Figure 3Optionally, the conveyor frame 210 includes a first frame 211, a first telescopic structure 212, a second telescopic structure 213, and a support member 214. The first frame 211 includes four first skeletons and multiple first connecting rods. The four first skeletons are located at the four corners of a rectangle and are perpendicular to the plane enclosed by the rectangle. The four first skeletons are arranged in parallel and enclose a rectangular space, in which the conveyor tray 240 is slidably disposed. Adjacent first skeletons are connected by at least one first connecting rod. The first telescopic structure 212 is connected to the first frame 211, the second telescopic structure 213 is connected to the telescopic end of the first frame 211, and the support member 214 is connected to the telescopic end of the second telescopic structure 213. The first telescopic structure 212 extends and retracts horizontally, and the second telescopic structure 213 extends and retracts vertically. The first telescopic structure 212 can move the support member 214 closer to or further away from the conveyor tray 240. When the support member 214 is close to the conveyor tray 240, it can be inserted between the bottom conveyor tray 240 and the upper conveyor tray 240 adjacent to the bottom conveyor tray 240. Then, the second telescopic structure 213 rises, and the support member 214 abuts against the annular folded edge 241 of the upper conveyor tray 240. Thus, through the cooperation of the second telescopic structure 213 and the support member 214, all the conveyor trays 240 located above the bottom layer are driven to rise a certain distance. The bottommost conveyor tray 240 is not subjected to the gravity of the other conveyor trays 240. Under the action of the conveyor belt assembly 220, the bottommost conveyor tray 240 can be conveyed normally.

[0042] It should be understood that the first telescopic structure 212, the second telescopic structure 213 and the support member 214 constitute a set of driving structures. Two sets of driving structures can be set on opposite sides of the first frame 211 to improve stability.

[0043] In addition, both the first telescopic structure 212 and the second telescopic structure 213 can be cylinders or hydraulic cylinders.

[0044] Please combine Figure 1 and Figure 2 In this embodiment, optionally, the conveyor belt assembly 220 includes a motor, two pulleys, and two conveyor belt bodies 221. The motor is connected to one of the two pulleys, and the two conveyor belt bodies 221 are both sleeved on the two pulleys and are spaced apart in the axial extension direction of the pulleys, forming a clearance area 222 between the two conveyor belt bodies 221. The conveyor tray 240 can be carried by both conveyor belt bodies 221 simultaneously for conveying.

[0045] Please combine Figure 4In this embodiment, optionally, the collection rack 230 includes a second frame 231, a third telescopic structure 232, and a one-way rotating member 233. The third telescopic structure 232 is connected to the second frame 231 and is used to drive the conveyor tray 240 conveyed from the conveyor belt assembly 220 to rise. The third telescopic structure 232 is located between the clearance area 222 between the two conveyor belt bodies 221 and can abut against the conveyor tray 240 located on the conveyor belt assembly 220 from below, thereby driving the conveyor tray 240 to rise. The one-way rotating member 233 is rotatably connected to the second frame 231 and has a gap between the one-way rotating member 233 and the support of the conveyor belt body 221. The vertical height of this gap is not less than the height of the conveyor tray 240, so that the conveyor tray 240 can enter the area enclosed by the second frame 231 from the inlet of the second frame 231 under the drive of the conveyor belt assembly 220. Meanwhile, when the unidirectional rotating member 233 rotates in the first direction, it can abut against the second frame 231 to limit the unidirectional rotating member 233 from continuing to rotate in the first direction. When the conveyor disc 240, which is in contact with the conveyor belt assembly 220, rises under the drive of the third telescopic structure 232, the annular folded edge 241 of the conveyor disc 240 can abut against the unidirectional rotating member 233 and drive the unidirectional rotating member 233 to rotate in a second direction opposite to the first direction. The annular folded edge 241 of the conveyor disc 240 can pass over the unidirectional rotating member 233. After the annular folded edge 241 of the conveyor disc 240 passes over the unidirectional rotating member 233, the unidirectional rotating member 233 rotates in the first direction under the action of gravity and abuts against the second frame 231. At this time, the conveyor disc 240 conveyed from the conveyor belt assembly 220 is collected. After the conveyor disc 240 passes over the unidirectional rotating member 233, it will drop a certain height under the action of gravity and abut against the unidirectional rotating member 233 again. The unidirectional rotating member 233 plays the role of supporting the conveyor disc 240.

[0046] It should be understood that two unidirectional rotating parts 233 can be provided and symmetrically arranged on opposite sides of the second frame 231, which can more stably support the conveyor plate 240.

[0047] In addition, the third telescopic structure 232 can be a cylinder or a hydraulic cylinder, etc.

[0048] Please combine Figure 2In this embodiment, optionally, the lifting assembly 250 includes a fourth telescopic structure 251 and a lifting plate 252. The fourth telescopic structure 251 can be configured as a cylinder or a hydraulic cylinder, and the lifting plate 252 is connected to the telescopic end of the fourth telescopic structure 251. The telescopic direction of the fourth telescopic structure 251 extends vertically, enabling the lifting plate 252 to rise and fall to approach or move away from the conveyor belt body 221. Furthermore, the lifting plate 252 is located within the area enclosed by the two conveyor belt bodies 221, thereby contacting the bottom of the conveyor disc 240 on the conveyor belt body 221 and causing the conveyor disc 240 to rise and move away from the conveyor belt body 221. Optionally, two lifting assemblies 250 can be provided and arranged at intervals in the conveying direction of the conveyor belt body 221, with an insertion area between the two lifting plates 252.

[0049] Please combine Figure 2Optionally, the positioning assembly 260 includes a telescopic unit 261 and a support plate 262. The support plate 262 is connected to the telescopic end of the telescopic unit 261, and the telescopic unit 261 is used to move the support plate 262 closer to or further away from the conveyor belt. The height of the support plate 262 is higher than the height of the conveyor belt body 221 to avoid interference with the conveyor belt body 221 when the support plate 262 is close to it. The support plate 262 can be positioned below the conveyor tray 240, which is lifted by two lifting plates 252. The support plate 262 and the two lifting plates 252 can also jointly support the conveyor tray 240. Specifically, the lifting plate 252 can be raised to a height higher than the support plate 262 to avoid interference between the support plate 262 and the lifting plate 252 when the support plate 262 is inserted below the conveyor plate 240. After the position of the support plate 262 is adjusted, the two lifting components 250 descend, and the conveyor plate 240 can be supported solely by the support plate 262 after the lifting components 250 descend. At this time, the telescopic unit 261 is activated, and the telescopic unit 261 can drive the conveyor plate 240 away from the conveyor belt body 221 through the support plate 262, thereby moving it to a position where it can receive the rock cuttings falling from the collection cylinder 160. In other words, through the cooperation of the lifting components 250 and the adjusting components 260, the conveyor plate 240 can be driven to reciprocate between the conveyor belt body 221 and the rock cuttings collection mechanism 100. When the rock cuttings collection mechanism 100 is in position, the conveyor tray 240 is not supported by the conveyor belt body 221. Rock cuttings falling from the collection cylinder 160 can smoothly enter the conveyor tray 240 without affecting the stability of the conveyor belt body 221. After the rock cuttings collection is completed, the adjustment component 260 transports the conveyor tray 240 above the conveyor belt body 221. The two lifting plates 252 rise and continue to rise to a certain height after contacting the bottom of the conveyor tray 240, causing the bottom of the conveyor tray 240 to separate from the support plate 262. The conveyor tray 240 is then supported only by the two lifting plates 252. Then, the telescopic unit 261 drives the support plate 262 back to its original position, and the fourth telescopic structure 251 drives the lifting plates 252 to descend. After descending to the set position, the conveyor tray 240 is supported only by the two conveyor belt bodies 221, and the conveyor tray 240 can be normally transported to the collection rack 230, where it is then positioned and stored.

[0050] In this embodiment, optionally, the automated rock cuttings analysis and acquisition device for the logging industry also includes a rock cuttings cleaning mechanism. The rock cuttings cleaning mechanism receives the rock cuttings conveyed from the rock cuttings conveying mechanism 200 and cleans them. The rock cuttings analysis mechanism receives the rock cuttings discharged from the rock cuttings cleaning mechanism. The rock cuttings cleaning mechanism can adopt a known existing structure, which will not be specifically described in this embodiment.

[0051] In addition, the rock cuttings analysis apparatus can be set as a fluorescence analysis device, which can adopt existing known structures, and will not be specifically described in this embodiment.

[0052] It should be noted that the conveyor tray 240 containing rock cuttings collected in the collection rack 230 can be transported to the rock cuttings cleaning mechanism by a robotic arm or conveyor belt, and the cleaned rock cuttings can also be transported to the rock cuttings analysis mechanism by a conveyor belt.

[0053] The automated cuttings analysis and acquisition device for the logging industry provided in this embodiment automates the entire cuttings analysis and acquisition process, reducing manual intervention and achieving a high degree of automation and efficiency.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
