Description

Technical Field

[0001] The present application belongs to the technical field of geological logging, and more specifically, relates to an automatic logging device. Background Art

[0002] During the drilling process, the drilling fluid will bring the rock blocks that have been broken by the drill bit underground to the surface. The rock blocks mixed in these materials are called drilling cuttings. The continuously obtained drilling cuttings can directly describe the geological planing surface of the formation, reflect the underground formation conditions and rock properties, and help to initially understand the oil and gas conditions of the formation. Due to the low cost of obtaining drilling cuttings, simple methods, timely reflection of underground conditions, and strong data systematization, it is an effective means of understanding geological logging.

[0003] In related technologies, drilling construction often needs to be carried out continuously for dozens of days or even longer, and it is required to take a rock eyebrow for geological analysis every 1-2m of drilling. The shortest sampling time interval must not be less than 2 minutes, and the weight of the sampled rock eyebrow is required to be around 500g. In order to ensure accurate sampling and obtain effective geological data, a certain number of workers are generally specially assigned to sample the drilling rock eyebrow. However, manual operations often have many uncontrollable factors, which affect the analysis of geological cuttings, causing confusion, and easily directly affecting the analysis of geological materials and the effect of oil exploration and development.

[0004] In particular, with the rapid development of drilling technology today, the drilling speed has been greatly improved. For example, the rapid drilling speed in today's drilling construction can reach 1min / m. Traditional manual sampling can basically not meet the requirements of rock cuttings sampling under such conditions, which can easily lead to the omission of rock cuttings, directly affecting the judgment of stratigraphic sequence lithology, and urgently needs to be improved.

[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a logging automation device. Figure 1-3The logging automation device comprises a circulating transport mechanism 1, a feeding mechanism 2, an exciting mechanism 3, a drilling fluid recovery mechanism 4, a cuttings cleaning mechanism 5, an imaging analysis mechanism 6, a drying and storing mechanism 7 and a screen box cleaning mechanism 8, wherein: the circulating transport mechanism 1 comprises a plurality of screen boxes 1-1 arranged in sequence, and the plurality of screen boxes 1-1 circulate along a closed path to sequentially pass through a feeding station, a drilling fluid recovery station, a cuttings cleaning station, an imaging analysis station, a drying and storing station and a screen box cleaning station, and sequentially perform the following at each station: 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 in 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 so that clean cuttings are retained 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 and dries 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 so that multiple cuttings sampling does not interfere with each other. In addition, the excitation mechanism 3 can reciprocate between the drilling fluid recovery station and the cuttings cleaning station to apply an excitation force to the screen box 1-1, promote the separation of the drilling fluid and cuttings in the material, and separate and filter the drilling fluid from the screen box 1-1.

[0035] Further, such as Figure 1 As shown, in some embodiments, the device further includes a transfer bin 9, which has an openable flap 9-1, and a circulating transport mechanism 1, a feeding mechanism 2, an excitation 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 are all arranged in the transfer bin 9. Under this design, the device is a transportable integrated logging automation device, which can be conveniently and quickly transported in an integrated manner to meet the needs of site changes.

[0036] Specifically, the transfer bin 9 preferably adopts a container-type structure with five closed sides and is provided with some feed holes, power holes, shutter ventilation holes, operating LCD screen and other structures. The remaining side of the transfer bin 9 is set as a flap door 9-1, and the flap door 9-1 is preferably driven by an electric cylinder / hydraulic cylinder / pneumatic cylinder to achieve automatic opening and closing, which is convenient for personnel to enter and exit and for inspection.

[0037] Preferably, an observation window is provided in the flap 9 - 1 , and the observation window is covered with transparent plexiglass to facilitate the user to observe the operation of the equipment inside the transfer warehouse 9 .

[0038] Furthermore, a temperature regulating mechanism is installed inside the transfer bin 9, and the temperature regulating mechanism is used to regulate the temperature inside the transfer bin 9 to prevent the device from freezing the pipe and causing blockage in a mine with a lower temperature. The temperature regulating mechanism includes but is not limited to air conditioning.

[0039] Furthermore, in this embodiment, the circulating transport mechanism 1 adopts a scheme of using a belt line to drive multiple screen boxes 1-1, so that the multiple screen boxes 1-1 can move in a closed path in a circular manner, so that the multiple screen boxes 1-1 can move in a specified 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 can be rotated back to the feeding station again, thereby realizing continuous sampling of cuttings and realizing water streamline synchronous operation.

[0040] Furthermore, the circulating transport mechanism 1 can use a circulating transmission structure such as a motor-driven transmission belt or a transmission chain to drive the movement of multiple screen boxes 1-1, or directly use a chain bucket conveyor with the screen box 1-1 as a hopper, as long as the circulating movement of the screen box 1-1 can be achieved. However, it should be noted that in the circulating transport mechanism 1, a space should be reserved for the rock chip cleaning mechanism 5 to perform infiltration cleaning of the screen box 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, the opening of the screen box 1-1 faces upwards, so as to receive materials, clean cuttings, image and analyze cuttings, etc. When the screen box 1-1 moves from the upper horizontal conveying section to the lower horizontal return section, the screen box 1-1 is adjusted from opening upwards to opening downwards, so that the cleaned cuttings in the screen box 1-1 automatically fall into the drying storage mechanism 7, thereby realizing the automatic transportation of cleaned cuttings.

[0042] Further, such as Figure 2-4 As shown, in order to quickly supply materials to the screen box 1-1, in this embodiment, the feed mechanism 2 includes a mud pump 2-1 with a discharge valve, and the liquid intake end of the mud pump 2-1 is connected to the feed port set on the transfer bin 9, and the material is pumped to the top of the screen box 1-1 through the feed pipe so that the screen box 1-1 can receive the material. Preferably, the mesh sizes of the multiple screen boxes 1-1 are different from each other to cope with rock cuttings of different particle sizes.

[0043] Furthermore, the 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 material carried by the screen box 1-1 is sufficient (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 for discharge to prevent material from overflowing and cleaning the screen box 1-1.

[0044] After the screen box 1-1 at the feeding station completes feeding, the screen box 1-1 moves to the drilling fluid recovery station, and a vibration force is applied to the screen box 1-1 through the vibration mechanism 3 to vibrate and separate the rock cuttings and the cleaning fluid in the material, so that the rock cuttings in the material are intercepted by the screen in the screen box 1-1, and the drilling fluid in the material is separated and filtered out from the screen to the drilling fluid recovery mechanism 4, thereby realizing the recovery of the drilling fluid.

[0045] Specifically, if Figure 2 and Figure 4 As shown, the drilling fluid recovery mechanism 4 includes but is not limited to the use of a collection box, and the excitation mechanism 3 includes a vibrator 3-1 with an end cover and a displacement assembly 3-2. The displacement assembly 3-2 is used to drive the vibrator 3-1 to move back and forth between the drilling fluid recovery station and the cuttings cleaning station, so that the end cover 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 the use of a linear motor, an electric slide, a multi-axis slide, etc. The vibrator is a prior art and will not be described in detail here.

[0046] After completing the recovery of the drilling fluid, the screen box 1-1 moves to the cuttings cleaning station, and the material in the screen box 1-1 is infiltrated and cleaned by the cuttings cleaning mechanism 5, and the screen box 1-1 at the cuttings cleaning station is vibrated by the vibration mechanism 3, so that clean cuttings are retained in the screen box 1-1.

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

[0048] Furthermore, after long-term use of the cleaning tank 5-1, impurities are usually deposited in the cleaning tank 5-1, and the cleaning liquid may not be clean. Figure 2 , Figure 3 and Figure 5 As shown, the cuttings cleaning mechanism 5 also includes a sewage pump 5-2 and a circulation purification device 5-3, wherein the inlet of the sewage pump 5-2 is connected to the bottom of the cleaning tank 5-1, and the outlet is outwardly used 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 medium circulation with the cleaning tank 5-1. The circulation purification device 5-3 can purify the cleaning liquid flowing through the circulation purification device 5-3, and the circulation purification device 5-3 can use a water filter, etc.

[0049] It is clear that after using the sewage pump 5-2 to discharge impurities, the user can actively add cleaning liquid to the cleaning tank 5-1 through the pipeline according to demand.

[0050] At the rock chip cleaning station, when the screen box 1-1 has not entered the rock chip cleaning station, the lifter drives the cleaning tank 5-1 to descend so that the cleaning tank 5-1 avoids the screen box 1-1. After the screen box 1-1 moves into the rock chip cleaning station, the lifter drives the cleaning tank 5-1 to rise so that the cleaning tank 5-1 is gradually covered on the outer periphery of the screen box 1-1, and continues to rise until the cleaning liquid in the cleaning tank 5-1 immerses the rock chips, and the rock chips are vibrated and cleaned by the vibrator 3-1 to achieve the cleaning of the rock chips. After the cleaning is completed, the lifter drives the cleaning tank 5-1 to descend so that the cleaning tank 5-1 is separated from the screen box 1-1, so that the screen box 1-1 moves to the next station.

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

[0052] Specifically, the imaging analysis mechanism 6 adopts a through-type photographic imaging detection method, which ensures the continuity of logging work, can track the situation of different depths of drilling work in real time, and facilitates the drilling team to adjust drilling parameters. As a preferred embodiment, the formation analysis mechanism includes an imaging analyzer with a through-type photographic imaging detection function.

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

[0054] Specifically, if Figure 2 , Figure 3 and Figure 5 As shown, the drying and storage mechanism 7 includes: a collecting bucket 7-1 for receiving rock cuttings, a manipulator 7-2 for taking and placing materials, a multi-station oven 7-3 for drying rock cuttings, a bagging and marking machine 7-4 for bagging and marking rock cuttings, and a storage box 7-5 for storing rock cuttings.

[0055] Among them, the collecting bucket 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, the screen box 1-1 rotates from the upper end to the lower end of the belt line / transmission chain under the drive of the belt line / transmission chain), the screen box 1-1 is adjusted from the opening facing upward to the opening facing downward, so that the rock cuttings fall into the screen box 1-1.

[0056] Among them, the manipulator 7-2 includes but is not limited to a four-axis linear module manipulator for picking up and discharging materials, thereby sending the materials into the multi-station oven 7-3. Preferably, the multi-station oven 7-3 uses an electric cylinder to automatically send and receive the baking tray, which is controlled by a control module to ensure that the drying beat corresponds to the rock chip cleaning beat. After the drying process is completed, the dried rock chips are sent to the bagging and marking machine 7-4. Finally, the manipulator 7-2 or the baking tray that can be automatically sent and received is used to send the materials into the storage box 7-5 for storage. The storage box 7-5 is preferably a hundred-grid box.

[0057] like Figure 2 As shown, after the cleaned rock cuttings in the sieve box 1-1 fall into the collecting bucket 7-1, the sieve box 1-1 continues to move to reach the sieve box cleaning station, and the sieve box 1-1 is cleaned by the sieve box cleaning mechanism 8 to ensure that multiple rock cuttings sampling do not interfere with each other. Among them, the sieve box cleaning mechanism 8 includes but is not limited to using the same components as the rock cutting cleaning mechanism 5.

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