Description

Technical Field

[0001] The present application relates to the technical field of mixed-phase fluid measurement, and in particular to a portable optical quantum mass absorption coefficient calibration device and method. Background Art

[0002] In the oil and gas industry, mixed-phase flow meters are used to measure the flow rates of various fluid media in oil and gas products. Photons of different energies emitted by a photon source pass through the measured substance and enter the detection system in a transmission manner. When the photons pass through the oil and gas mixed-phase flow, some of them will be absorbed by different substances. Different media have different mass absorption coefficients. The detection system captures each incoming photon, quantifies its energy, and classifies and counts it according to different energy levels to form an energy spectrum.

[0003] By analyzing the effect of the measured medium on the energy spectrum, the holdup of each phase in the finished crude oil can be calculated, and thus the flow rate of each phase fluid medium can be calculated. Therefore, determining the mass absorption coefficient of different media is a necessary prerequisite for mixed phase flow measurement.

[0004] Currently, absorption coefficient calibration is typically performed in the laboratory. Samples of varying phases are taken back to the laboratory for calibration, and the calibrated absorption coefficients are then incorporated into the flowmeter for field measurements. This is a time-consuming and labor-intensive process, requiring significant labor costs. Furthermore, field measurement environments are complex and the media are highly variable. Currently, there is a lack of a portable mass absorption coefficient calibration device for field use. Summary of the Invention

[0093] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0094] In order to achieve the above objectives,

[0095] Reference Figure 1-Figure 5The embodiment of the present application provides a portable optical quantum mass absorption coefficient calibration device, comprising a housing 1, wherein the housing 1 is provided with a cavity 11 communicating with the outside and a cover 12 for sealing the cavity 11, wherein the cavity 11 is provided with an optical quantum probe 2, an optical quantum source 3, a container 4, a power supply, and a processor 6.

[0096] The placement container 4 is detachably arranged on the shell 1 , and the placement container 4 is arranged between the photon probe 2 and the photon source 3 . The photon probe 2 , the photon source 3 and the power supply are all electrically connected through the processor 6 .

[0097] As the fundamental structure of the entire device, housing 1 not only provides necessary protection but also defines the device's shape and dimensions. It features a cavity 11, which houses the device's core components. Cover 12 seals cavity 11 to ensure stability and accuracy in the measurement environment.

[0098] The cavity 11 is the core space inside the device, used to install and fix various components. The cover 12 is used to seal the cavity 11 to prevent external interference factors such as light and dust from entering and affecting the measurement results.

[0099] As a key component for measuring the light quantum mass absorption coefficient, the light quantum probe 2 is responsible for receiving and converting light signals into electrical signals for subsequent processing and analysis.

[0100] The photon source 3 is used to provide a stable and controllable light source for illuminating the calibration object. The type and intensity of the photon source 3 can be adjusted as needed to meet different calibration requirements.

[0101] The container 4 is used to hold the sample or solution to be calibrated. The material, shape, and size of the container 4 should be selected according to the characteristics of the calibration object to ensure measurement accuracy and repeatability.

[0102] The power supply provides power to the entire device, ensuring the normal operation of all components. The power supply design should take into account portability and battery life to meet the needs of on-site calibration.

[0103] Processor 6 serves as the device's control and data processing center. It receives information from the photon probe 2 and photon source 3, processes and analyzes the data, and ultimately outputs the calibration results. Processor 6 also features a user interface and functionality to facilitate user operation and results viewing.

[0104] Among them, the shell 1 is provided with a rotating block 13, and the rotating block 13 is provided with a limiting groove 14. The limiting groove 14 is used to install and place the container 4. After the rotating block 13 enters the shell 1, the photon source 3, the photon probe 2 and the limiting groove 14 are located on the same axis.

[0105] Optionally, this embodiment uses a high-performance, long-life lithium battery or rechargeable battery pack to provide stable power support. The power supply is designed with a power display and a charging port, so that the user can easily understand the power status and charge at any time.

[0106] Furthermore, the power supply can be equipped with a power management module and an energy-saving mode. The power management module can intelligently allocate power resources to ensure the normal operation of various components. The energy-saving mode can automatically reduce power consumption when not in use, extending battery life.

[0107] Processor 6, a high-performance, low-power microprocessor or embedded system, is responsible for data processing, sending and receiving control instructions, and displaying the user interface. Processor 6 also interfaces with display screen 15 to form a touchscreen user interface, wireless communication module, and remote control system. The touchscreen user interface offers an intuitive interface and a wide range of functional options, making operation and configuration easy. The wireless communication module supports communication protocols such as Bluetooth and Wi-Fi, enabling connection and data transmission with devices such as smartphones and tablets. The remote control system allows users to monitor and control the device in real time via a remote terminal.

[0108] During use, the user first places the sample or solution to be calibrated into container 4, then mounts container 4 on the rotating block 13. By rotating the rotating block 13, container 4 is moved to the desired position. The processor 6 then activates the photon source 3, causing it to emit a stable light beam to illuminate the calibration object. The photon probe 2 receives the light signal after it passes through the calibration object, converts it into an electrical signal, and transmits it to the processor 6. The processor 6 processes and analyzes the received signal, ultimately calculating the photon mass absorption coefficient and displaying it on the display 15.

[0109] It can be understood that the placement container 4 of this embodiment is provided with a magnetic stirrer 41 , a temperature sensor 42 and a heating mechanism, and the magnetic stirrer 41 , the temperature sensor 42 and the heating mechanism are all electrically connected to the processor 6 .

[0110] For magnetic stirrers, you can use the TH-MC1 magnetic stirrer from Tuohe Technology. Made of 6062 aluminum, it is lightweight and durable. It provides stable magnetic stirring and meets basic experimental needs.

[0111] It can be understood that the photon detector of this embodiment is integrated with a temperature measurement module, which can perform temperature correction on the calibration process. The test liquids of different temperatures and different mixed phase states are factory calibrated before leaving the factory. Steps one to three are repeated to obtain the functional relationship between oil and water at different temperatures. The temperature measurement module is built into the calculation module and can be used in conjunction with the temperature sensor 42 placed in the container 4.

[0112] In the specific implementation process, a suitable temperature correction model (such as a linear correction model or a nonlinear correction model) is selected, and the portable photon mass absorption coefficient calibration device is repeatedly simulated with different working conditions and different temperatures to monitor the actual temperature value measured by the photon detector to obtain multiple sets of temperature data, each set of temperature data including a measured temperature value and an actual temperature value corresponding to the measured temperature value. According to the error between the measured temperature value and the corresponding actual temperature value, the parameters of the temperature correction model (such as the temperature correction coefficient) are adjusted until the error between the measured temperature value and the actual temperature value is less than the preset error, and the temperature correction model is obtained. In actual application, the actual temperature value measured by the photon detector is substituted into the temperature correction model to obtain the corrected temperature value.

[0113] On this basis, after long-term use, the measurement accuracy of existing optical quantum measurement equipment is often difficult to guarantee due to factors such as light source aging and changes in detector sensitivity.

[0114] By setting up the calibration mechanism 5, the optical quantum measurement device can be calibrated regularly to ensure the accuracy and reliability of the measurement results.

[0115] Specifically, the sample pre-storage device 51 is internally configured with multiple independent storage units designed to store different types of samples, including pure water samples, pure oil samples, and pure solid samples. Each sample can be properly stored in its own dedicated storage unit. The device and the external housing 1 are connected by a snap-on method, allowing for easy and detachable connection, making it easy for users to assemble or disassemble as needed.

[0116] To further enhance the sample storage environment, a temperature regulator and temperature detector are also incorporated into the sample pre-storage device 51. The temperature regulator integrates both heating and cooling functions. Its core component may be a high-efficiency temperature control element such as a Peltier module. This, combined with a precise temperature sensor 42 and a feedback system, ensures that the temperature within the storage unit is maintained within a preset range.

[0117] The sample processing device 52 is primarily responsible for sample pretreatment, with the stirring element being a key component. The stirring element's primary function is to ensure the homogeneity of the oily sample before measurement, effectively preventing calibration errors caused by stratification or sedimentation. Given the high viscosity and tendency of oily substances to stratify, the stirring element's efficiency is particularly important.

[0118] Furthermore, given that the agitator is in contact with oily substances for extended periods of time, the choice of material is crucial. To ensure its durability and reliability, we use corrosion- and wear-resistant materials, such as stainless steel or materials with special coatings. These materials effectively resist erosion by oily substances, thereby extending the agitator's service life.

[0119] After long-term use, the measurement accuracy of existing optical quantum measurement equipment is often difficult to guarantee due to factors such as light source aging and changes in detector sensitivity.

[0120] Among them, in this embodiment, the photon source 3 can emit photoelectrons of three energy levels by emitting the first energy level group photons, the second energy level group photons and the third energy level group photons, and are detected and recorded accordingly by the photon detector. The energy of the first energy level group photons is 31keV, the energy of the second energy level group photons is 81keV, and the energy of the third energy level group photons is 356keV.

[0124] That is, the portable photon mass absorption coefficient calibration device is placed at the measurement site, and the empty container 4 is directly counted and calibrated. When the photon source 3 emits the first energy level group photons, the second energy level group photons and the third energy level group photons, the number of photons detected by the photon probe 2 is recorded as N. 01 、N 02 and N 03 ;

When the placement container is filled with pure water sample:

[0147] When container 4 is placed to hold a pure solid sample:

[0148] When the photon source emits 3 first energy level group photons, 2nd energy level group photons and 3rd energy level group photons, the number of photons detected by the photon probe 2 is recorded as, N 固1、 N 固2、 N 固3；

[0149] The absorption coefficient of the solid is calculated as follows:

[0154] K 固 is the mass absorption coefficient of the solid at 356keV;

[0155] m 固 is the mass of the solid.

[0156] Thus, the absorption coefficients of pure water samples, pure oil samples and pure solid samples can be obtained.

[0157] S3. Obtain the mass of each component in the substance to be tested and calculate the absorption coefficient of the substance to be tested:

[0158] By separating the substance to be tested, the mass of the components in the substance to be tested is obtained, which is recorded as m x and m y ;

[0159] The solution to be tested is any two phases among oil, gas, water and solid;

[0169] N x is the absorption coefficient of the mixed phase test liquid;

[0170] By measuring the weight of different components in the substance to be tested, the absorption coefficient of the test solution can be obtained.

[0171] When it is necessary to test the substances collected on site, follow-up tests are performed based on the different conditions of the substances:

[0172] When the substance to be tested is any two-phase mixture of oil, gas, water, or solid; for example, the sample cup is filled with real liquid test samples containing oil and water respectively, and the test calibration is performed. At this time, the absorption coefficient is N x Calculate according to the following formula.

[0181] m is the mass of the mixed phase liquid to be tested;

[0182] N x is the absorption coefficient of the mixed phase test solution.

[0183] By combining the above three equations, we can obtain N x The numerical value is to obtain the mass absorption coefficient of the substance to be tested.

For example, when it is necessary to detect an oil and water mixture, the water content η of the substance to be tested and the mass m of the substance to be tested can be obtained by first performing a water content test on the substance to be tested.

[0195] The mass absorption coefficient of the substance to be measured is calibrated based on the water content η of the substance to be measured and the mass m of the substance to be measured.
