Description

Technical Field

[0001] This invention relates to the field of drilling engineering technology, and more specifically, to a digital sand sampler and its usage method. Background Technology

[0002] Cuttings logging is an important service in geological logging, serving as a crucial basis for identifying formation lithology, determining stratigraphic positions, and discovering and evaluating oil and gas reservoirs. Cuttings, as return material from the formation, require manual sampling to ensure accuracy. In the field, cuttings undergo a series of processes including sampling, cleaning, drying, labeling, and bagging to become qualified samples.

[0003] Currently, rock cuttings collection methods both domestically and internationally primarily rely on manual retrieval. This involves manual tasks such as cleaning and marking the rock cuttings. The processed rock cuttings must meet industry standards, such as a sand sample weight requirement of 500g, a baking temperature not exceeding 80℃, and complete drying to remove all moisture. Simultaneously, manual marking of the rock cuttings is necessary, including information such as depth, stratigraphic position, lithological name, and a brief lithological description. The entire process is complex and prone to errors, leading to inaccurate rock cutting information. This can hinder on-site rock cutting description, geological evaluation, and subsequent rock cuttings verification, resulting in low work efficiency.

[0004] Therefore, how to solve the problem of low efficiency in existing artificial cuttings logging methods is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a digital sand sample tray that can automate the cuttings logging process and improve the efficiency of cuttings logging.

[0006] Another objective of this invention is to provide a method for using the aforementioned digital sand sample pan, which improves the standardization, automation, and digitization of rock cuttings samples, significantly enhances the automation level of rock cuttings cleaning, and lays the foundation for accurate rock cuttings identification and stratigraphic evaluation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0011] The detection device is located on the sand sample pan body and is used to detect the temperature, humidity and weight of rock fragments in the sand sample pan body in real time.

[0012] The control device is located on the top of the sand sample pan body, and is connected to the RFID radio frequency tag and the detection device.

[0022] Control sand sample tray initialization;

[0023] After cleaning, the rock cuttings were transferred to the sand sample pan body to drain the water;

[0024] The sand sample tray is transferred to the drying oven for drying. At the same time, the temperature and humidity of the rock cuttings are detected in real time by temperature and humidity sensors, and the detected temperature and humidity data are sent to the microcontroller.

[0025] After the rock chips are dried, the gravity sensor is controlled to detect the weight of the rock chips and send the detected weight data to the microcontroller. If the weight of the rock chips meets the standard, a standardized rock chip sample is formed.

The bottom of the sand sample tray body is provided with a filter screen and a draining tank. The filter screen is located above the draining tank. The rock cuttings that have just been washed contain a lot of water. When the rock cuttings are placed on the sand sample tray body, the water is filtered through the filter screen and the excess water is drained into the draining tank, thereby realizing the process of draining the rock cuttings.

[0029] The control device is located on top of the sand sample pan and is signal-connected to the RFID tag and detection device. The control device acquires information about the rock cuttings detected by the RFID tag and detection device. The detection device, located on the sand sample pan itself, is used to monitor the temperature, humidity, and weight of the rock cuttings within the pan in real time. It monitors the temperature, humidity, and weight of the rock cuttings during drying and sends the data to the control device. The control device then regulates the drying parameters to ensure a smooth drying process. The RFID tag, located on top of the sand sample pan, collects data from the rock cuttings and sends this data to the control device. Employing RFID and automated control technologies ensures the rock cuttings are completely dried at the specified temperature, resulting in standardized samples that meet weight and humidity standards. This standardization and automation of rock cuttings logging improves the efficiency of the process. Attached Figure Description

[0043] The core of this invention is to provide a digital sand sample tray that automates the cuttings logging process, thereby improving the efficiency of cuttings logging operations. Another core aspect of this invention is to provide a method for using the aforementioned digital sand sample tray, which enhances the standardization, automation, and digitization of cuttings samples, significantly improving the automation level of cuttings cleaning and laying the foundation for accurate cuttings identification and formation evaluation.

[0044] Please refer to Figure 1 and Figure 2 A digital sand sample tray includes a sand sample tray body 1, an RFID radio frequency tag 3, a detection device 4, and a control device 5.

[0045] Specifically, the bottom of the sand sample tray body 1 is equipped with a filter screen 2 and a draining trough. The filter screen 2 is located above the draining trough. The freshly washed rock fragments contain a lot of water. When the rock fragments are placed on the sand sample tray body 1, the water is filtered through the filter screen 2, and the excess water is drained into the draining trough, thereby realizing the process of draining the rock fragments.

[0046] The control device 5 is located on top of the sand sample pan and is signal-connected to both the RFID tag 3 and the detection device 4. The control device 5 acquires the rock cuttings information detected by the RFID tag 3 and the detection device 4. The detection device 4 is located on the sand sample pan body 1 and is used to monitor the temperature, humidity, and weight of the rock cuttings within the sand sample pan body 1 in real time. The detection device 4 monitors the temperature, humidity, and weight of the rock cuttings during drying in real time and sends the measured data to the control device 5. The control device 5 controls the drying parameters of the rock cuttings to ensure the drying process proceeds smoothly. The RFID tag 3 is located on top of the sand sample pan body 1 and is used to collect data from the rock cuttings. The RFID tag 3 sends the collected data to the control device 5. By employing RFID radio frequency technology and automated control technology, the rock cuttings are ensured to be completely dried at the specified temperature, so that the dried sample meets the standards for weight and humidity, forming a standardized rock cuttings sample. This enables the standardization and automation of rock cuttings logging, improving the efficiency of rock cuttings logging operations.

[0047] The sand sample tray body 1 is equipped with an RFID radio frequency tag 3 on one side for information reading during the automated logging process. The bottom of the sand sample tray body 1 is equipped with a filter screen 2 to drain the water in the rock cuttings and ensure that fine particles in the rock cuttings are filtered out, so that all samples are completely preserved. The bottom of the sand sample tray body 1 is equipped with a drainage trough so that the water in the rock cuttings is filtered into the drainage trough after passing through the filter screen 2, which is conducive to the rapid drying of the rock cuttings.

[0048] The digital sand sample tray set up in the above manner can realize the standardization and digitization of well logging sand sample collection, improve the level of digital management and application of sand samples, and ensure the formation of rock cutting samples that meet industry standards by adopting automated collection and digital information technology, thereby improving the standardization, automation and digitization of rock cutting samples and providing support for subsequent lithological identification and stratigraphic evaluation.

[0049] In the above embodiment, the control device 5 includes a microcontroller 51 and a display screen 52. Both the microcontroller 51 and the display screen 52 are located on the top of the sand sample pan body 1, and the microcontroller 51 and the display screen 52 are connected by signals.

[0050] It should be noted that the sand sample pan body 1 is equipped with a microcontroller 51, which is mainly used for data acquisition from the temperature sensor 41, humidity sensor 42 and gravity sensor 43. The microcontroller 51 has a data acquisition and display program installed, which has data storage, display and alarm functions. It can control the display screen 52, which is used to display information such as the well depth, lithology name, and stratigraphy of the sand sample. It is also used to display the temperature and humidity of the sand sample. By switching the display of information such as the depth, lithology, and stratigraphy of the sand sample, users can easily understand various information about the rock cuttings in the current sand sample pan body 1.

[0051] Among them, the display screen 52 is an electronic display screen 52, which uses products with high temperature resistance and waterproof rating.

[0052] In the above case, the sand sample tray body 1 is provided with a first mounting groove for mounting the microcontroller 51. The first mounting groove is provided with an openable top cover. The top cover is provided with a wire opening and is a high-temperature resistant and waterproof cover.

[0053] Understandably, the sand sample pan body 1 has a pre-reserved first mounting groove for installing the microcontroller 51, and the top is designed as a flip cover to facilitate the placement of the microcontroller 51. In addition, the top cover has corresponding connection wire ports to enable the microcontroller 51 to be connected to the temperature sensor 41, humidity sensor 42 and gravity sensor 43.

[0054] The top cover is a high-temperature resistant and waterproof cover, which can prevent the top cover from melting due to the drying temperature during the drying process of the sand sample tray body 1, and can also prevent water from entering from the top cover and causing damage to the microcontroller 51.

[0055] Furthermore, a second mounting groove for installing RFID radio frequency tags 3 is provided on one side of the sand sample tray body 1, and a heat-insulating and waterproof layer is provided on the second mounting groove.

[0056] It should be noted that a second mounting groove for installing RFID radio frequency tag 3 is reserved on one side of the sand sample tray body 1. RFID radio frequency tag 3 is embedded in one side of the sand sample tray body 1. The size of the second mounting groove is the same as that of RFID radio frequency tag 3. The surface of the second mounting groove is sprayed with heat-insulating and waterproof material to form a heat-insulating and waterproof layer. The upper part of RFID radio frequency tag 3 is encapsulated with high temperature resistant material and waterproofed, while ensuring that RFID radio frequency tag 3 can communicate normally.

[0057] In the above embodiment, the detection device 4 includes a temperature sensor 41, a humidity sensor 42, and a gravity sensor 43. The temperature sensor 41, humidity sensor 42, and gravity sensor 43 are all connected to the microcontroller 51 via wires.

[0058] Understandably, temperature sensor 41 is used to measure the temperature of rock cuttings. When the sand sample pan body 1 is being baked, if the temperature of the rock cuttings is higher than the set temperature, an alarm message is issued to cool it down. Humidity sensor 42 is responsible for collecting the humidity of the rock cuttings. When the humidity of the rock cuttings is higher than the set humidity when the sand sample pan body 1 is being baked, an alarm message is issued to extend the baking time. Gravity sensor 43 is responsible for collecting the weight of the rock cuttings. When the collected weight is less than or greater than the set weight range, an alarm message is issued.

[0059] Temperature sensor 41 detects the temperature of the rock cuttings to ensure that the temperature meets the requirements; humidity sensor 42 detects the humidity of the rock cuttings to ensure that the humidity meets the requirements; gravity sensor 43 measures the weight of the rock cuttings to ensure that the weight of the rock cuttings meets the sampling standards; through the above series of measurements, a rock cuttings sample that meets the standards is formed.

[0060] Based on the above embodiment, the temperature sensor 41, humidity sensor 42 and gravity sensor 43 are all located in the interlayer space between the bottom of the sand sample tray body 1 and the filter screen 2. The bottom of the sand sample tray body 1 is provided with mounting positions for installing the temperature sensor 41, humidity sensor 42 and gravity sensor 43. The temperature sensor 41, humidity sensor 42 and gravity sensor 43 are all connected to the sand sample tray body 1 by binding ropes.

[0061] It should be noted that the side of the sand sample tray body 1 is reserved for the installation positions of temperature sensor 41 and humidity sensor 42, and the bottom middle position of the sand sample tray body 1 is reserved for the installation position of gravity sensor 43. Temperature sensor 41 and humidity sensor 42 are reliably fixed to sand sample tray body 1 by binding rope, and gravity sensor 43 is reliably fixed to filter screen 2 by binding rope.

[0062] In the above embodiment, gripping handles 11 are provided on the edges of both sides of the sand sample disc body 1.

[0063] Understandably, the sand sample tray body 1 adopts a rectangular design, and the two sides of the sand sample tray body 1 are designed with gripping handles 11 to facilitate manual handling and automated robotic arm gripping.

[0064] The sand sample tray body 1 has a sand sample tray slot installed at the bottom. The size and position of the sand sample tray slot are matched with the automatic conveyor belt to lock and fix it on the automatic conveyor belt, ensuring that the sand sample tray body 1 is stably transported on the conveyor belt.

[0065] As a preferred embodiment, the sand sample tray body 1 is made of aluminum alloy.

[0066] It should be noted that the sand sample tray body 1 is made of aluminum alloy, which facilitates heat conduction during rock cutting drying and is beneficial for the rapid drying of rock cuttings.

[0067] In the above case, filter 2 is a high mesh count filter 2.

[0068] Understandably, the bottom of the sand sample pan body 1 is designed with a double-layer filter screen 2, using a high-mesh filter screen 2 to ensure that the rock fragments drain water quickly and that fine rock fragments such as siltstone can be retained.

[0069] Please refer to Figure 3 A method for using a digital sand sample tray, applied to the aforementioned digital sand sample tray, the method including:

[0070] Step S1: Initialize the control sand sample tray;

[0071] Step S2: Control the transfer of the cleaned rock cuttings to the sand sample pan body 1 to drain the water;

[0072] Step S3: Control the sand sample tray body 1 to transfer to the drying box for drying treatment. At the same time, the temperature and humidity of the rock cuttings are detected in real time by temperature sensor 41 and humidity sensor 42, and the detected temperature and humidity data are sent to the microcontroller 51.

[0073] Step S4: After the rock chips are dried, control the gravity sensor 43 to detect the weight of the rock chips and send the detected weight data to the microcontroller 51. If the weight of the rock chips meets the standard, a standardized rock chip sample is formed. Then, the standardized rock chip sample is tested and analyzed, and the analysis results are stored in the microcontroller 51 and displayed on the display screen 52.

[0074] Step S5: Control the RFID radio frequency tag 3 to automatically read all the information of the rock cuttings, and complete the automatic generation and printing of the rock cuttings tag;

[0075] Step S6: Control the rock cuttings samples to be bagged and labeled.

[0076] It should be noted that before placing the rock cuttings onto the sand sample tray body 1, the digital initialization of the sand sample tray is first completed. The system obtains the sand sample tray information through the RFID radio frequency tag 3 and stores data such as the well number and well depth of the rock cuttings into the system. Then, the rock cuttings are placed on the sand sample tray body 1. The sand sample that has just been cleaned contains a lot of water. The water is filtered through the filter screen 2, and the excess water is drained into the drain tank. After the rock cuttings have drained, the sand sample tray body 1 is placed into the drying oven by a robotic arm. The temperature sensor 41 and humidity sensor 42 on the sand sample tray body 1 collect the temperature and humidity parameters of the rock cuttings in real time and send them to the microcontroller 51. The baking temperature and humidity of the rock cuttings are controlled within the industry standard. If the parameters exceed the standard, the microcontroller 51 will issue an alarm and display it on the display screen 52 to prompt the user to take action.

[0077] Humidity sensor 42 ensures complete drying of rock cuttings. After the sand sample tray body 1 is dried in the drying oven, gravity sensor 43 collects the weight of the rock cuttings to check if the weight meets the standard. When the weight of the rock cuttings meets the standard, a standardized rock cutting sample conforming to industry standards is formed. Then, other analytical equipment is used to detect the rock cuttings in the sand sample tray body 1, including rock cuttings image acquisition and rock cuttings elemental analysis. The analysis results are stored in the microcontroller 51 and displayed on the display screen 52 as needed. All information of the rock cuttings is automatically read by RFID radio frequency tag 3, enabling the system to automatically generate and print rock cuttings labels. The system controls the bagging of rock cuttings samples, putting the rock cuttings in the sand sample tray body 1 into labeled sand sample bags. After the rock cuttings are marked and bagged, the rock cuttings information stored in the sand sample tray is cleared, and the sand sample tray enters the next cycle of its life cycle.

[0078] In summary, the digital sand sample tray provided by this invention addresses the shortcomings of existing manual cuttings logging methods, such as low efficiency, cumbersome operation, and low level of informatization. It fully leverages the advantages of digitalization and automation, employing RFID radio frequency technology and 51 microcontroller automation control technology to ensure that cuttings are completely dried at a specified temperature. After drying, the samples meet standards in terms of weight, humidity, etc., forming standardized cuttings samples. Simultaneously, various data from the cuttings are collected for digital information display and sharing, allowing users to easily access various information about the cuttings. The system also automatically completes functions such as label printing using the cuttings information, improving the standardization, automation, and digitization of cuttings samples. This significantly enhances the automation level of cuttings cleaning, laying the foundation for accurate cuttings identification and formation evaluation.
