Fig. 2 schematically illustrates a schematic structural diagram of a system for monitoring an operating condition of a pipeline according to another embodiment of the present application. As shown in fig. 2, the mobile monitoring device may include:
the displacement sensor 3 is used for acquiring displacement data of a target position;
the pressure sensor 4 is used for acquiring pressure data of a target position;
the temperature sensor 5 is used for acquiring temperature data of a target position;
the ultrasonic wall thickness detector 6 is used for acquiring the thickness data of the pipeline wall at the target position;
the flowmeter 7 is used for acquiring flow data of a target position;
a water level monitor 8 for collecting water level data of a target position;
wherein, the displacement sensor 3, the pressure sensor 4, the temperature sensor 5, the ultrasonic wall thickness detector 6, the flowmeter 7 and the water level monitor 8 are connected through cables.
In particular, the mobile monitoring device is located within a pipe 2, the pipe 2 being within a casing 1. Gas injection and gas production can be performed through the inner annulus of the pipe 2. The pipe 2 may be a pipe having a uniform inner diameter and a uniform outer diameter, or a pipe having a non-uniform inner diameter or a non-uniform outer diameter or a non-uniform inner and outer diameters. The pipe 2 may be a single pipe or a pipe string composed of a plurality of pipes. Both ends of the uppermost part and the lowermost part of the pipeline 2 are fixed and cannot move, the upper part is connected with a wellhead device, and the lower part is connected with a packer to ensure the sealing property of the pipeline.
The system may measure real-time data of target parameters of a target location by lifting or lowering the mobile monitoring device. The movable monitoring device comprises a displacement sensor 3, a pressure sensor 4, a temperature sensor 5, an ultrasonic wall thickness detector 6, a flowmeter 7 and a water level monitor 8.
The displacement sensor 3 is a linear device belonging to metal induction. The displacement sensor can be divided into an analog type and a digital type according to different conversion forms of measured variables. Common displacement sensors include potentiometer-type displacement sensors, inductive displacement sensors, capacitive displacement sensors, eddy current displacement sensors, hall-type displacement sensors, and the like. In the acceleration process of the movable monitoring device, the mass block is subjected to inertia force measurement, an acceleration value is calculated by utilizing a Newton second law, and then a specific coordinate is obtained through acceleration and speed. During fixed measurement, the position of the movable monitoring device can be obtained through the displacement sensor 3; in the movement measurement, the depth coordinates of the movable monitoring device at different time points can be obtained through the displacement sensor 3. Due to the special application environment, a displacement sensor with a small volume needs to be selected, for example, a hall displacement sensor can be used. The pressure sensor 4 is a device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. The temperature sensor 5 refers to a sensor which can sense temperature and convert it into a usable output signal. The phenomena of expansion with heat and contraction with cold at different temperatures are very obvious. The gas production process is a process of producing high-temperature gas in the stratum along the inside of the pipeline, wherein obvious temperature difference occurs in the pipeline, and the temperature of a well head and the temperature of a well bottom are higher. The gas injection process is a process of injecting low-temperature gas at the well head into the well bottom, and the temperatures of the well head and the well bottom are relatively low. By monitoring the temperature change in different injection-production periods, the pipeline expansion amount caused by the temperature effect is analyzed, and whether the pipeline is buckled and deformed or not is comprehensively judged.
The ultrasonic wall thickness probe 6 can perform thickness measurements according to the ultrasonic pulse reflection principle. The ultrasonic wall thickness probe includes a transmitting portion and a receiving portion. An ultrasonic wave is transmitted by the transmitting portion, the ultrasonic wave is reflected after encountering an obstacle, and the reflected ultrasonic wave is received by the receiving portion. The thickness data of the pipe wall of the pipe can thus be determined from the transit time and the sound velocity. The transit time is the time of transmission from the transmission of the ultrasound waves to the reception of the echo signal. The flow meter 7 is a meter that indicates the measured flow rate or the total amount of fluid in a selected time interval. The water level detector 8 is an instrument that can measure water level data. The movable monitoring device can measure real-time data of target parameters at multiple positions so as to analyze the real-time data subsequently, thereby improving the accuracy of judging the current running state of the pipeline.

Specifically, as shown in fig. 2, the movable monitoring device is susceptible to corrosion in the pipeline, and in order to ensure safe operation of the movable monitoring device, a protective shell 9 needs to be disposed outside the movable monitoring device. In addition, the protective case 9 may have a shock absorbing function, avoiding measurement deviation due to instability of the movable monitoring device. Through setting up the protective housing, avoid the material of pipe-line transportation to produce the influence to displacement sensor 3, pressure sensor 4, temperature sensor 5, ultrasonic wave wall thickness detector 6, flowmeter 7 and water level monitor 8 to can reduce displacement sensor 3, pressure sensor 4, temperature sensor 5, ultrasonic wave wall thickness detector 6, flowmeter 7 and water level monitor 8's vibrations.

Specifically, as shown in fig. 2, a cable 10 may connect the movable monitoring device, the display device, and the analysis device. Cables are materials used for power, communication and related transmission applications, including multi-core cables and mono-core cables. The real-time data collected by the movable monitoring device can be transmitted to the display device through the cable 10, the display device can transmit the real-time data to the analysis device through the cable, and the analysis device can transmit the alarm signal to the display device through the cable. In one example, a multi-core cable may be used. The multi-core cable comprises a plurality of transmission lines, each transmission line corresponds to one channel, and each transmission line is used for transmitting real-time data of a target parameter corresponding to a current channel. Through cable junction portable monitoring device, display device and analytical equipment to utilize the cable to carry out data transmission, can satisfy long distance's data transmission's demand, improve data transmission's stability.
In the embodiment of the present application, the real-time data of each target parameter is transmitted through two channels.
Specifically, in order to improve stability and safety in the signal transmission process, real-time data of each target parameter is transmitted by using two channels. In the case of a single channel failure, a backup channel is used for data transmission. Real-time data and signals collected by the movable monitoring device are transmitted through the two channels, stability and safety in the signal transmission process are improved, and the problem of data loss caused by channel faults is avoided.
