Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement equipment, and more specifically, to a liquid level collector device with dual-channel ultrasonic rapid sampling and non-destructive filtering. Background Art

[0002] In recent years, with the extensive implementation of deep drilling in complex geological environments, the risks of drilling fluid overflow and loss have increased sharply, posing a severe challenge to well control safety. The dynamic monitoring of the volume of the circulation tank, as a key measure to prevent drilling overflow and leakage accidents, can timely detect and warn potential problems by monitoring the changes in drilling fluid in real time.

[0003] In the drilling operation in complex geological environments, flow monitoring faces multiple challenges. Firstly, the existing monitoring equipment is large in size, which is not only inconvenient to carry, but also difficult to build a platform on complex terrains, greatly increasing the operation cost and time. Secondly, the monitoring system usually consists of various devices such as flow meters, sensors, and data collectors. If not scientifically arranged, the on-site wiring is likely to be intricate, making management and maintenance cumbersome. More seriously, the independent operation of devices lacks a unified management and coordination mechanism, resulting in frequent occurrence of information island phenomena, making it difficult to ensure data consistency and timeliness, and easily affecting decision-making efficiency and accuracy.

[0004] In addition, mechanical impacts during the drilling process, such as external factors like continuous vibration and accidental collisions, may not only cause the device housing to crack, internal components to loosen or even be damaged, affecting the operation progress and efficiency.

[0005] Currently, the monitoring of the drilling fluid outlet flow mainly relies on a baffle-type flow meter operated manually. However, during the long-term continuous measurement process, impurities in the drilling fluid will gradually adhere to and accumulate on the baffle, causing a change in the weight of the baffle, resulting in a large measurement error and affecting the reliability and stability of the entire flow monitoring.

[0006] The Chinese utility model patent with the patent name of "A Portable Drilling Fluid Flow Detection Device" and the publication number of CN219733327U, which has been publicly disclosed, includes a detection box, an ultrasonic flow sensor, a data transmission line, a control component, a display component, and a power supply component. This detection device integrates the control component, the display component, and the power supply component into the detection box, contacts the ultrasonic flow sensor with the drilling fluid pipeline, and uses ultrasonic waves for detection. The operation is simple, and it is convenient to carry and transport. However, if the ultrasonic flow sensor fails and the device cannot detect and handle it in time, it is easy to reduce the drilling efficiency; more seriously, it is impossible to detect dangers such as well leakage in time, increasing the operation risk.

[0032] Embodiment 1

[0033] Please refer to Figures 1-4, the utility model provides a liquid level collector device with dual-channel ultrasonic rapid sampling and non-destructive filtering. The same as the prior art, it includes an explosion-proof box body, a box cover hinged to the explosion-proof box body, a data monitoring and processing module, two sensor modules, and multiple connector interfaces 2; the data monitoring and processing module is fixed inside the explosion-proof box body, and multiple connector interfaces 2 are all embedded on the side of the explosion-proof box body. The data monitoring and processing module is connected to the sensor module through the connector interface 2; the data monitoring and processing module includes an analog quantity acquisition module, an industrial control computer, and a power module, and the analog quantity acquisition module, the industrial control computer, and the power module are connected to each other pairwise.

[0034] It should be noted that the power module receives external power through the connector.

[0035] Different from the prior art, the analog quantity acquisition module is provided with a first acquisition channel and a second acquisition channel. The input ends of the first acquisition channel and the second acquisition channel are respectively connected to the sensor module through different connector interfaces 2; the output ends of the first acquisition channel and the second acquisition channel are respectively connected to the industrial control computer.

[0036] The data monitoring and processing module further includes a switch control module, and the industrial control computer controls the switching of the first acquisition channel and the second acquisition channel through the switch control module.

[0037] This device adopts a dual-channel design, and each channel is connected to a different ultrasonic sensor. When this device detects that the currently working sensor module fails, this device will immediately inform the staff; at the same time, the device switches the data acquisition to another channel to ensure the continuity and stability of the data acquisition process, so as to realize the real-time monitoring of the drilling operation and effectively prevent the occurrence of potential risks such as well leakage.

[0038] The analog quantity acquisition module further includes two judgment modules. The input ends of the two judgment modules are respectively connected to the output ends of the first acquisition channel and the second acquisition channel in one-to-one correspondence, and the output ends of the two judgment modules are both connected to the industrial control computer.

[0039] The judgment module includes a voltage follower, a positive bias signal conditioner, and a window comparator.

The output end of the voltage follower is connected to the input end of the positive bias signal conditioner, the output end of the positive bias signal conditioner is connected to the window comparator, and the output end of the window comparator is used as the output end of the judgment module.

[0040] It should be explained that the voltage follower is used to isolate the input circuit and the output circuit to protect the front-stage circuit from the influence of the load in the output circuit; during the propagation and reception of ultrasonic signals, they may be affected by various factors, resulting in the offset of the signal baseline. The positive bias signal conditioner introduces a positive bias voltage to ensure that the signal remains within a suitable level range during processing and to protect the subsequent circuit; the window comparator is used to ensure that the signal fluctuates within a predetermined threshold. If the input signal exceeds the signal range, it is determined that the sensor is faulty, and a warning signal is sent to the industrial control computer at this time.

[0041] It should be explained that when the warning signal is received, the industrial control computer immediately takes measures to receive and analyze the abnormal data to ensure that these abnormal data will not accumulate for a long time and cause substantial damage to the industrial control computer itself. At the same time, the industrial control computer will quickly send a notice to the staff through the connected switch to remind them to pay attention to and handle the current abnormal situation.

[0042] Furthermore, in this embodiment, as Figure 3 shown, the judgment module includes a voltage follower U1, operational amplifiers U2, comparators U3, U4, diodes D1, D2, a capacitor C1, and resistors R1, R2, R3, R4, R5, R6, R7, R8, R9, R10;

[0044] Specifically, the positive input terminal of the voltage follower U1 is set as the con_in input terminal.

The negative input terminal of the voltage follower U1, the output terminal of the voltage follower U1, and one end of the resistor R1 are connected. The other end of the resistor R1, one end of the resistor R10, one end of the resistor R2, and the positive input terminal of the operational amplifier U2 are connected. The other end of the resistor R10 is connected to the positive power supply; the other end of the resistor R2 is grounded; the negative input terminal of the operational amplifier U2, one end of the resistor R9, and one end of the resistor R3 are connected. The other end of the resistor R9 is grounded. The pin 2 of the operational amplifier U2 is connected to the positive power supply, and the pin 5 is connected to the negative power supply; the output terminal of the operational amplifier U2, the other end of the resistor R3, one end of the resistor R4, one end of the capacitor C1, the positive input terminal of the comparator U3, and the negative input terminal of the comparator U4 are connected. The other end of the resistor R4, the other end of the capacitor C1, and one end of the resistor R7 are connected and grounded. The other end of the resistor R7, one end of the resistor R8, and the positive input terminal of the comparator U4 are connected. The other end of the resistor R8 is connected to the pin 4 of the comparator U4 and is connected to the positive power supply. The pin 5 of the comparator U4 is grounded. The output terminal of the comparator U4 is connected to the anode of the diode D2; the silver glue of the comparator U3 is connected to the positive power supply, and the pin 5 is grounded. The negative input terminal of the comparator U3, one end of the resistor R5, and one end of the resistor R6 are connected. The other end of the resistor R5 is connected to the positive power supply, and the other end of the resistor R6 is grounded. The output terminal of the comparator U3 is connected to the anode of the diode D1. The cathode of the diode D1 and the cathode of the diode D2 are connected, and the con_out output terminal is set here.

[0045] It should be explained that a judgment module is connected to a collection channel. The con_in input terminal is connected to the input terminal of the judgment module and the output terminal of the collection channel. The con_out output terminal is connected to the industrial control computer.

[0046] The data monitoring processor module further includes a switch, which is respectively connected to the industrial control computer and the connector interface 2.

[0050] The ultrasonic sensor is connected to the data monitoring processor module through the connector interface 2. The transmitting end of the ultrasonic sensor emits ultrasonic signals, which propagate in the air until they hit the drilling fluid surface and are reflected back. The receiving end of the ultrasonic sensor receives the reflected signals and transmits them to the monitoring processor module for processing and analysis. According to the analysis results, potential dangerous situations such as well leakage are evaluated and judged.

[0051] The mud scraper is arranged on the front side of the transmitting end and the receiving end of the ultrasonic sensor. The mud scraper is connected to the data monitoring processor module through the connector interface 2. The mud scraper is used to remove the mud and other impurities attached to the surface of the sensor module, so as to ensure that the sensor can maintain high-precision measurement and detection capabilities.

[0052] The data monitoring processor module also includes a time relay, which is respectively connected to the industrial control computer and the power supply module. The time relay controls the reciprocating movement of the mud scraper through the connector interface 2.

[0053] It should be explained that the time relay is controlled by the industrial control computer. The operator sets the reciprocating time parameters of the mud scraper at the monitoring end and sends them to the switch through the network. The switch forwards the instruction to the industrial control computer, and the industrial control computer analyzes the parameters and controls the time relay. The time relay controls the mud scraper according to the instruction to achieve the set reciprocating movement cycle.
