Description

Technical Field

[0001] This application belongs to the field of geological logging technology, and more specifically, relates to an automated logging device. Background Technology

[0002] During drilling, drilling fluid carries rock fragments broken by the drill bit to the surface; these rock fragments mixed in with the drilling material are called drill cuttings. Continuously obtained drill cuttings can directly describe the geological profile of the formation, reflecting the downhole formation conditions and rock properties, and helping to provide a preliminary understanding of the formation's oil and gas content. Because drill cuttings are inexpensive to obtain, easy to use, provide timely downhole condition information, and offer a highly systematic data set, they are an effective cognitive tool in geological logging.

[0003] In related technologies, drilling operations often last for dozens of days or even longer, requiring the sampling of cuttings for geological analysis every 1-2 meters of drilling, with a minimum sampling interval of 2 minutes and a sample weight of approximately 500g. To ensure accurate sampling and obtain effective geological data, a certain number of workers are typically assigned to collect drilling cuttings. However, manual operations are often subject to many uncontrollable factors, affecting the analysis of geological cuttings and causing confusion, which can directly impact the analysis of geological materials and the effectiveness of oil exploration and development.

[0004] In particular, with the rapid development of drilling technology today, drilling speed has been greatly improved. For example, the speed of rapid drilling in current drilling operations can reach 1 min / m. Traditional manual sampling can hardly meet the requirements of cuttings sampling under such conditions, which can easily lead to the omission of cuttings and directly affect the judgment of stratigraphic sequence lithology, which urgently needs to be improved. Summary of the Invention

[0005] In view of the deficiencies or improvement needs of the existing technology, this application provides an automated logging device, which aims to improve the automation level of cuttings sampling operations, as well as improve the efficiency and quality of cuttings sampling.

The multiple screen boxes move in a closed loop to perform the following: a feeding mechanism injects material into the screen box; a drilling fluid recovery mechanism recovers drilling fluid from the material in the screen box; a cuttings cleaning mechanism cleans the material in the screen box to leave clean cuttings in the screen box; an imaging analysis mechanism performs imaging analysis on the clean cuttings in the screen box; a drying and storage mechanism receives, dries and stores the clean cuttings in the screen box; and a screen box cleaning mechanism cleans the screen box.

[0008] The excitation mechanism is used to apply excitation force to the screen boxes at the drilling fluid recovery mechanism and the cuttings cleaning mechanism, so as to promote the separation and filtration of drilling fluid from the screen boxes and promote the cleaning of cuttings.

When the screen box moves from the upper horizontal conveying section to the lower horizontal return section, the screen box is adjusted from having its opening facing upwards to having its opening facing downwards, so that the clean rock chips inside the screen box automatically fall into the drying and storage mechanism.

[0012] As a further preferred embodiment, the feeding mechanism includes a mud pump with a discharge valve, and a weighing sensor is installed at the bottom of the screen box. The mud pump is used to draw material into the screen box. When the weighing sensor detects that the screen box has reached a preset weight, the mud pump discharges the material outside the screen box through the discharge valve.

[0013] As a further preferred embodiment, the excitation mechanism includes an exciter and a displacement component, the displacement component being used to drive the displacement adjustment of the exciter.

[0014] As a further preferred embodiment, the rock cuttings cleaning mechanism includes a cleaning tank and a lifting device, wherein the lifting device is used to drive the cleaning tank to move up and down so that the material in the screen box can be immersed in the cleaning liquid in the cleaning tank.

[0015] As a further preferred embodiment, the rock cuttings cleaning mechanism further includes a sludge pump and a circulation purification device, wherein:

[0016] The inlet of the sludge pump is connected to the bottom of the cleaning tank, and the outlet faces outward to discharge impurities.

[0017] The circulating purification device forms a media circulation with the cleaning tank, and the circulating purification device is used to purify the cleaning solution.

[0018] As a further preferred embodiment, the imaging analysis mechanism is an imaging analyzer with through-type photographic imaging detection function.

[0019] As a further preferred embodiment, the drying and storage mechanism includes: a collection hopper for receiving rock cuttings, a robotic arm for picking up and placing materials, a multi-station drying oven for drying rock cuttings, and a storage box for storing rock cuttings.

[0020] As a further preferred embodiment, the automated device also includes a transfer chamber with an openable hinged door, and the circulating transport mechanism, feeding mechanism, vibration mechanism, drilling fluid recovery mechanism, cuttings cleaning mechanism, imaging analysis mechanism, drying and storage mechanism, and screen box cleaning mechanism are all located inside the transfer chamber.

[0021] As a further preferred embodiment, the transfer chamber is equipped with a temperature regulation mechanism.

[0022] In summary, compared with the prior art, the technical solutions conceived in this application have the following main technical advantages:

[0023] 1. This device is a transferable integrated automated logging device that can process multiple batches of drilling materials in a continuous production line manner.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an automated logging device. (Refer to...) Figure 1-3The automated logging device includes a circulating transport mechanism 1, a feeding mechanism 2, a vibration mechanism 3, a drilling fluid recovery mechanism 4, a cuttings cleaning mechanism 5, an imaging analysis mechanism 6, a drying and storage mechanism 7, and a screen box cleaning mechanism 8. The circulating transport mechanism 1 includes multiple screen boxes 1-1 arranged in sequence. The multiple screen boxes 1-1 move in a closed path to pass through the feeding station, the drilling fluid recovery station, the cuttings cleaning station, the imaging analysis station, the drying and storage station, and the screen box cleaning station in sequence. At each station, the following is performed in sequence: At the feeding station, the feeding mechanism 2 injects material into the screen box 1-1. At the drilling fluid recovery station, the drilling fluid recovery mechanism 4 recovers the drilling fluid from the material in the screen box 1-1; at the cuttings cleaning station, the cuttings cleaning mechanism 5 cleans the material in the screen box 1-1 to ensure that clean cuttings remain in the screen box 1-1; at the imaging analysis station, the imaging analysis mechanism 6 performs imaging analysis on the clean cuttings in the screen box 1-1; at the drying and storage station, the drying and storage mechanism 7 receives, dries, and stores the clean cuttings; at the screen box cleaning station, the screen box cleaning mechanism 8 cleans the screen box 1-1 to ensure that the screen box 1-1 is clean and that multiple cuttings samplings do not interfere with each other. Additionally, the vibration mechanism 3 can reciprocate between the drilling fluid recovery station and the cuttings cleaning station to apply vibration force to the screen box 1-1, promoting the separation of drilling fluid and cuttings in the material, allowing the drilling fluid to be separated and filtered out from the screen box 1-1.

[0035] Furthermore, such as Figure 1 As shown, in some embodiments, the device further includes a transfer chamber 9, which has an openable / closeable hinged door 9-1. The circulating transport mechanism 1, the feeding mechanism 2, the vibration mechanism 3, the drilling fluid recovery mechanism 4, the cuttings cleaning mechanism 5, the imaging analysis mechanism 6, the drying and storage mechanism 7, and the screen box cleaning mechanism 8 are all housed within the transfer chamber 9. With this design, the device is a transferable integrated automated logging device, capable of convenient and quick integrated transfer, meeting the needs of site changes.

[0036] Specifically, the transfer compartment 9 preferably adopts a container-type structure, which is enclosed on five sides and is equipped with some material inlet, power supply hole, louvered ventilation hole, operation LCD screen and other structures. The remaining side of the transfer compartment 9 is set as a flip door 9-1, and the flip door 9-1 is preferably driven by electric cylinder / hydraulic cylinder / pneumatic cylinder to realize automatic opening and closing, which facilitates personnel entry and exit and inspection.

[0037] Preferably, the flip door 9-1 is equipped with an observation window, which is covered with transparent plexiglass, so that users can easily observe the operation of the equipment inside the transfer compartment 9.

[0038] Furthermore, the transfer chamber 9 is equipped with a temperature regulation mechanism to regulate the internal temperature of the transfer chamber 9, preventing the material from freezing and causing blockages in the pipelines in low-temperature mines. This temperature regulation mechanism includes, but is not limited to, the use of air conditioning.

[0039] Furthermore, in this embodiment, the circulating transport mechanism 1 adopts a belt conveyor to drive multiple screen boxes 1-1, so that the multiple screen boxes 1-1 move in a closed path in a circular motion. This allows the multiple screen boxes 1-1 to move along a designated direction through the feeding station, drilling fluid recovery station, cuttings cleaning station, imaging analysis station, drying and storage station, and screen box cleaning station, and then return to the feeding station, thereby achieving continuous sampling of cuttings and realizing streamlined synchronous operation.

[0040] Furthermore, the circulating transport mechanism 1 can use a motor-driven transmission belt, transmission chain, or other circulating transmission structure to move multiple screen boxes 1-1, or directly use a chain bucket conveyor with the screen boxes 1-1 as hoppers, as long as it can achieve the circulating movement of the screen boxes 1-1. However, it should be noted that in the circulating transport mechanism 1, sufficient space should be provided for the rock cuttings cleaning mechanism 5 to wet and clean the screen boxes 1-1.

[0041] In this design, the closed path includes an upper horizontal conveying section and a lower horizontal return section. When the screen box 1-1 is in the upper horizontal conveying section, its opening faces upwards to facilitate material receiving, rock cuttings cleaning, and rock cuttings imaging analysis. When the screen box 1-1 moves from the upper horizontal conveying section to the lower horizontal return section, it adjusts from having its opening facing upwards to having its opening facing downwards, allowing the clean rock cuttings inside the screen box 1-1 to automatically fall into the drying and storage mechanism 7, thus achieving automatic transfer of clean rock cuttings.

[0042] Furthermore, such as Figure 2-4 As shown, to rapidly supply material to the screen box 1-1, in this embodiment, the feeding mechanism 2 includes a mud pump 2-1 with a discharge valve. The liquid intake end of the mud pump 2-1 is connected to the feed inlet provided on the transfer chamber 9, and the material is drawn to the screen box 1-1 through the feed pipe so that the screen box 1-1 can receive the material. Preferably, the mesh counts of the multiple screen boxes 1-1 are different to accommodate rock cuttings of different particle sizes.

[0043] Furthermore, this device also includes a control module and a weighing sensor 10. The weighing sensor 10 is installed at the bottom of the screen box 1-1 to detect the weight of the screen box 1-1. The control module is connected to various mechanisms and components such as the weighing sensor 10. When the control module detects that the screen box 1-1 is carrying enough material (for example, when the weight of the screen box reaches a preset weight), the control module controls the discharge valve of the mud pump 2-1 to open and discharge the material, preventing material from overflowing and cleaning the screen box 1-1.

[0044] After the material is fed into the screen box 1-1 at the feeding station, the screen box 1-1 moves to the drilling fluid recovery station. The excitation mechanism 3 applies an excitation force to the screen box 1-1 to separate the rock cuttings and cleaning fluid in the material. The rock cuttings in the material are intercepted by the screen and trapped in the screen box 1-1, while the drilling fluid in the material is separated and filtered out from the screen and filtered into the drilling fluid recovery mechanism 4, thus realizing the recovery of drilling fluid.

[0045] Specifically, such as Figure 2 and Figure 4 As shown, the drilling fluid recovery mechanism 4 includes, but is not limited to, a collection box. The vibration mechanism 3 includes a vibrator 3-1 with an end cap and a displacement assembly 3-2. The displacement assembly 3-2 drives the vibrator 3-1 to reciprocate between the drilling fluid recovery station and the cuttings cleaning station, so that the end cap of the vibrator 3-1 can cover the opening of the screen box 1-1. The displacement assembly 3-2 includes, but is not limited to, a linear motor, an electric slide, or a multi-axis slide. The vibrator is existing technology and will not be described in detail here.

[0046] After the drilling fluid recovery is completed, the screen box 1-1 is moved to the cuttings cleaning station. The material in the screen box 1-1 is soaked and cleaned by the cuttings cleaning mechanism 5. The vibration mechanism 3 applies a vibration force to the screen box 1-1 at the cuttings cleaning station so that clean cuttings are left in the screen box 1-1.

[0047] Specifically, such as Figure 2 As shown, the rock cuttings cleaning mechanism 5 includes a cleaning tank 5-1 and a lifting device. The lifting device is used to drive the cleaning tank 5-1 to move up and down, and the lifting device includes, but is not limited to, an electric cylinder. The cleaning tank 5-1 has a top opening and contains cleaning fluid, which includes, but is not limited to, water.

[0048] Furthermore, after prolonged use, impurities typically accumulate inside the cleaning tank 5-1, and the cleaning solution may also become less clean. Therefore, such as... Figure 2 , Figure 3 and Figure 5 As shown, the rock cuttings cleaning mechanism 5 also includes a sludge pump 5-2 and a circulation purification device 5-3. The inlet of the sludge pump 5-2 is connected to the bottom of the cleaning tank 5-1, and the outlet faces outward to discharge impurities. The inlet and outlet of the circulation purification device 5-3 are both connected to the cleaning tank 5-1, and the circulation purification device 5-3 is used to form a media circulation with the cleaning tank 5-1. The circulation purification device 5-3 can purify the cleaning fluid flowing through it, and can be a water filter or similar device.

[0049] It is clear that after the sludge pump 5-2 is used to discharge impurities, the user can actively add cleaning fluid to the cleaning tank 5-1 through the pipeline as needed.

[0050] At the rock cuttings cleaning station, before the screen box 1-1 enters the station, the lifting device lowers the cleaning tank 5-1 to allow it to avoid the screen box 1-1. Once the screen box 1-1 has entered the station, the lifting device raises the cleaning tank 5-1, gradually enclosing it around the screen box 1-1. This continues until the cleaning fluid in the tank submerges the rock cuttings. The vibrator 3-1 then vibrates and cleans the rock cuttings. After cleaning, the lifting device lowers the cleaning tank 5-1, separating it from the screen box 1-1 so that the screen box 1-1 can move to the next station.

[0051] After the sieve box 1-1 completes the rock cuttings cleaning at the rock cuttings cleaning station, the sieve box 1-1 will move into the imaging analysis station and perform imaging analysis of the rock cuttings through the imaging analysis mechanism 6.

[0052] Specifically, the imaging analysis unit 6 employs a through-feed photographic imaging detection method, which ensures the continuity of logging operations and enables real-time tracking of drilling conditions at different depths, facilitating adjustments to drilling parameters by the drilling team. Preferably, the forming analysis unit includes an imaging analyzer with through-feed photographic imaging detection capabilities.

[0053] After imaging analysis, the sieve box 1-1 will be moved to the drying and storage station, where the rock cuttings inside the sieve box 1-1 will be put into the drying and storage mechanism for drying and storage, so as to achieve archiving of the rock cuttings.

[0054] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the drying and storage mechanism 7 includes: a collection hopper 7-1 for receiving rock chips, a robotic arm 7-2 for picking up and discharging materials, a multi-station drying oven 7-3 for drying rock chips, a bagging and marking machine 7-4 for bagging and marking rock chips, and a storage box 7-5 for storing rock chips.

[0055] The collecting hopper 7-1 is located below the screen box 1-1. When the screen box 1-1 moves from the upper horizontal conveying section to the lower horizontal return section (for example, when the screen box 1-1 rotates from the upper end in the forward direction to the lower end of the belt / transmission chain in the opposite direction under the drive of the belt / transmission chain), the screen box 1-1 is adjusted from opening upward to opening downward, so that rock cuttings fall into the screen box 1-1.

[0056] The robotic arm 7-2 includes, but is not limited to, a four-axis linear module robotic arm for picking up and unloading materials, thereby sending the materials into the multi-station drying oven 7-3. Preferably, the multi-station drying oven 7-3 uses an electric cylinder for automatic tray feeding and receiving, controlled by a control module to ensure that the drying cycle corresponds to the rock chip washing cycle. After the drying process is completed, the dried rock chips are sent to the bagging and marking machine 7-4. Finally, the robotic arm 7-2 or an automatically feeding and receiving tray is used to send the materials into the storage box 7-5 for storage. The storage box 7-5 is preferably a 100-compartment box.

[0057] like Figure 2 As shown, after the clean rock cuttings in the sieve box 1-1 fall into the collection hopper 7-1, the sieve box 1-1 continues to move to the sieve box cleaning station, where the sieve box 1-1 is cleaned by the sieve box cleaning mechanism 8, ensuring that multiple rock cuttings samplings do not interfere with each other. The sieve box cleaning mechanism 8 includes, but is not limited to, using the same components as the rock cuttings cleaning mechanism 5.

[0058] Under this design, the device has many advantages such as simple structure, high reliability, wide adaptability, and high degree of automation. It can process multiple batches of drilling materials in a continuous production line, thereby effectively improving the quality of cuttings logging data and the accuracy of cuttings collection. It can improve the cuttings profile matching rate, reduce the impact of manual operation, reduce the workload of logging and data collection personnel, and improve work efficiency and accuracy. At the same time, it can reduce the number of on-site logging and data collection personnel, and reduce labor risks and labor intensity.
