Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement equipment, in particular to an integrated bass sound wave liquid level measurement processing control device. Background Art

[0002] In recent years, the scale of domestic oil and gas well exploration and development has continued to expand, and drilling operations have continued to advance to deeper formations, which has brought many problems. Well leakage, overflow, etc. are accidents that are often encountered during drilling, which have a great impact on the drilling process. Therefore, after the well leakage occurs, the location of the leaking layer should be determined promptly and accurately so that effective measures can be taken in time to deal with it. At present, the acoustic wave method for measuring the liquid level depth of the oil well is widely used by various oil fields due to its non-contact measurement characteristics. It calculates the liquid level depth of the oil well based on the product of the time delay of the liquid surface reflection wave and the speed of sound. Based on this depth data, it can be further analyzed and evaluated whether the oil well has potential safety risks such as well leakage and overflow, while minimizing the physical interference and damage to the measured liquid.

[0003] In the prior art, conventional drilling fluid level measurement, processing and control equipment includes gas explosion guns, high-pressure nitrogen cylinders, oil and gas well analyzers, etc. The gas explosion gun is combined with a high-pressure nitrogen cylinder to generate strong pulse sound waves by firing air burst bombs or operating air cannons. The sound waves will be reflected when they hit the drilling fluid surface, and the reflected echo signals will be received and analyzed by the oil and gas well analyzer. Based on the analysis results, it is determined whether there are potential dangers such as well leakage and overflow. There are also some ultrasonic level measurement, processing and control equipment, which include a sound wave processing system, a sound generator, a microphone and a notebook. The measurement principle is that the notebook controls the sound generator to emit sound waves, and the sound waves will be reflected when they hit the liquid surface. The microphone receives the reflected echo signals and transmits them to the sound wave processing system. The sound wave processing system processes them and transmits them to the notebook. The notebook calculates and analyzes the depth of the oil well liquid surface based on the product of the time delay of the liquid surface reflection wave and the speed of sound. Based on the analysis results, it is determined whether there are potential dangers such as well leakage and overflow.

[0004] In drilling operations, traditional and some existing drilling fluid level measurement, processing and control equipment have obvious shortcomings. The main problem is that the modules are independent of each other, resulting in a scattered on-site layout. Especially in complex environments, the overall system appears chaotic and disordered; and operators need to frequently shuttle between different locations to adjust modules, which greatly increases the complexity of operations; the independent operation of equipment lacks a unified management and coordination mechanism, and data consistency and timeliness are difficult to ensure; each module is large in size and the connection between modules is complex, making the transportation process cumbersome and easy to damage, limiting the portability of the equipment.

[0005] Therefore, it is of great significance to solve the problems of scattered modules, complex operation, poor portability and large space occupied by drilling fluid level measurement equipment. Utility Model Content

[0029] Example 1

[0030] In the prior art, the ultrasonic level measurement and processing control equipment includes a sound wave processing system, a sound generator, a microphone and a notebook which are dispersedly arranged at various places in the site. The sound wave processing system and the notebook are connected and both are placed at the monitoring end, which is set at the measurement site; the sound generator is arranged above the drilling fluid surface, and the microphone is placed around the sound generator to recover the reflected sound wave signal; the notebook is respectively connected to the sound wave processing system and the sound generator, and the microphone is connected to the sound wave processing system;

[0031] It needs to be explained that at the drilling fluid level measurement site, the laptop remotely controls the sound generator through physical connections, and the sound wave signals captured by the microphone are directly transmitted to the sound wave processing system through physical cables. This design provides effective physical isolation protection for the sound wave processing system and the laptop when facing potential dangers such as blowouts, thereby enhancing the safety of the system. However, this configuration of multiple physical connections makes the measurement site appear complicated, which not only affects the cleanliness of the working environment, but also increases the impact of external environmental factors on the equipment, which may weaken the stability of the sound wave measurement and the reliability of the data.

[0032] Reference Figure 1-Figure 5 The utility model provides an integrated bass acoustic wave liquid level measurement, processing and control device, including a cabinet, a cabinet door hinged to the cabinet, a valve system 7 matched with the cabinet, and a plurality of connector interfaces are embedded on the outer side of the cabinet; an explosion-proof box 1, a storage compartment 2, and an equipment accommodating cavity 3 are arranged inside the cabinet, an information processing system is arranged in the explosion-proof box 1, a sound-generating and receiving system is arranged in the equipment accommodating cavity 3, and the storage compartment 2 is used to store external accessories; the information processing system is connected to the sound-generating and receiving system, and the information processing system is connected to the valve system 7 through a connector interface; the information processing system includes an electrical equipment module and an installation frame, the installation frame is fixed to the cabinet, and the electrical equipment module is fixed in the installation frame.

[0033] It should be explained that the external accessories are placed in the storage compartment 2, which ensures the safety of the external accessories during transportation and improves the portability of the device.

[0037] It should be noted that a touch screen 4 is embedded on the outside of the explosion-proof box cover, and the touch screen 4 is connected to the electrical equipment module; an increased safety waterproof door is also hinged on the outside of the explosion-proof box cover for protecting the touch screen 4. The touch screen 4 is used to display various data for operators to view in real time. The operator can also send control signals to the electrical equipment module through the touch screen 4 to control the operation of each module; the increased safety waterproof door is used to protect the touch screen 4 and ensure that the touch screen 4 can operate stably at the measurement site.

[0038] The sound-generating and receiving system includes a woofer 9, a microphone, and a fixed frame. The microphone is arranged in front of the sound-generating end of the woofer 9, and the sound receiving end of the microphone is far away from the sound-generating end of the woofer 9. The fixed frame is fixed in the equipment accommodating chamber 3. The woofer 9 and the microphone are both fixed in the fixed frame. The woofer 9 is used to emit the original sound wave signal, which is reflected after contacting the drilling fluid surface, and the microphone is used to receive the echo signal after reflection.

[0039] It should be explained that, compared with high-frequency ultrasonic waves, the infrasound waves emitted by the mid-bass speaker 9 of the utility model have higher safety, lower operating costs and smaller measurement errors in oil well measurement; in addition, due to the strong penetrating power of infrasound waves, it is more suitable for drilling fluid containing suspended particles or impurities in this measurement.

[0040] The valve system 7 includes a flexible pipe 8, an electric ball valve, and a main pipe. One end of the flexible pipe 8 is connected to one end of the main pipe, and the other end of the flexible pipe 8 is connected to the cabinet and to the sound generating and receiving system. The electric ball valve is arranged on the main pipe, and the electric ball valve is controlled by the information processing system.

[0041] It needs to be explained that both the flexible pipe 8 and the main pipe serve as channels for sound wave transmission, and the electrical equipment module controls the switching state of the main pipe through an electric ball valve; the sound waves emitted by the generating and receiving system are transmitted to the pipeline where the drilling fluid is located through the flexible pipe 8 and the main pipe in turn, and the reflected sound waves are transmitted to the generating and receiving system through the main pipe and the flexible pipe 8 in turn.

[0042] The electrical equipment module includes an industrial computer, a relay, a power module, a communication module, and an echo processing module. The industrial computer is connected to the relay, the communication module, and the echo processing module respectively; the power module is connected to the industrial computer, the relay, the communication module, and the echo processing module respectively.

[0044] The electrical equipment module also includes a temperature detection module, which is connected to the industrial computer and the echo processing module respectively, and is used to comprehensively monitor the ambient temperature of the measurement site.

[0045] It should be explained that, given that the measurement site is usually faced with a high temperature environment, and temperature fluctuations have a significant impact on measurement accuracy and equipment performance, the potential interference of temperature on the quality of the echo signal must be fully considered. At the same time, the adverse effects of high temperature on the stable operation of electrical equipment in the cabinet must also be considered. The temperature detection module monitors temperature data in real time, which can not only compensate the echo signal in time, but also remind the operator of high temperature in the cabinet.

[0046] Specifically, if Figure 5 The temperature detection module includes a comparator U1, a thermistor U2, a capacitor C1, a transistor Q4, and resistors R1, R2, R3, R4, R6, and R7;

[0049] It should be noted that the OUT1 output terminal is connected to the echo processing module, and the OUT1 output terminal outputs the field temperature signal to the echo processing module. The echo processing module performs temperature compensation on the received echo signal according to the temperature signal to ensure the accuracy of the echo signal; the OUT2 output terminal is connected to the industrial computer, and after the industrial computer receives the high level output from the OUT2 output terminal, it issues a temperature warning to the operator.

[0051] It should be noted that the connector interface used to connect the electrical equipment module and the wireless transmission module 6 includes but is not limited to the antenna interface.

[0052] For ease of understanding, the working process of the device is described below:
