First, referring to fig. 1, fig. 1 shows a schematic structural diagram of a monitoring system provided by the present application, which mainly includes four parts, namely, an underground "open hole section" diameter monitoring device, a paperless recorder data storage device, a data remote transmission device, and a remote data analysis terminal.
It will be appreciated that the monitoring system may be distinguished by underground and aboveground portions.
For the underground part, the diameter monitoring device of the underground open hole section is configured at a target pipe column, the target pipe column is a pipe column part consisting of a salt layer stratum structure in an injection and production pipe column of the salt cavern gas storage, and the injection and production pipe column of the salt cavern gas storage also comprises a metal pipe column connected with the target pipe column.
It can be understood that the target string, namely the "open hole section" of the injection-production string of the salt cavern gas storage is arranged to prevent the whole injection-production string from being damaged by tension due to the tensile strain at the top of the salt cavity, and is directly obtained by hollowing out the salt layer stratum of the underground environment to form a hollow pipeline which can be connected with the metal string to form the whole injection-production string.
And for the overground part, the paperless recorder data storage device, the data remote transmission device and the remote data analysis terminal are respectively arranged at preset positions on the ground.
It can be understood that the paperless recorder data storage device, the data remote transmission device and the remote data analysis terminal correspond to three aspects of storage, transmission and analysis processing of the diameter monitoring result, and correspondingly, the diameter monitoring processing for the naked eye section in the application specifically includes the following contents:
the diameter monitoring device of the underground naked eye section acquires the diameter of a target tubular column through a sensor configured by the diameter monitoring device, the diameter monitoring result is transmitted to the paperless recorder data storage device through a transmission line, the paperless recorder data storage device stores the diameter monitoring result transmitted by the diameter monitoring device of the underground naked eye section through the transmission line, and the diameter monitoring result is transmitted to a remote data analysis terminal through a communication module configured by the data remote transmission device, so that the remote data analysis terminal analyzes the diameter monitoring result.
It can be found that, because the diameter monitoring device of the underground 'open hole section' is installed in the drilling process of the data well or other excavation projects, compared with the method of adopting indirect analysis modes such as injection and production efficiency analysis, stratum creep and the like to estimate the diameter change of the 'open hole section', the diameter of the 'open hole section' can be conveniently and directly observed through the diameter monitoring device of the underground 'open hole section', thereby bringing the characteristic of high precision and providing rich, fine or powerful data support for the analysis and processing of the diameter monitoring result of the subsequent remote data analysis terminal.
Further, it can be understood by referring to fig. 2 showing another schematic structural diagram of the monitoring system of the present application, in fig. 2, 1 is a downhole "open hole section" diameter monitoring device, 2 is a wired transmission cable, 3 is a wellbore device, 4 is a paperless recorder data storage device, 5 is a data remote transmission device, and 6 is a remote data analysis terminal.
The diameter monitoring device of the downhole open hole section can be configured with corresponding sensors to acquire the diameter of the open hole section according to a preset diameter monitoring mode, in other words, the diameter monitoring device of the downhole open hole section can mainly comprise the sensors, and even can be directly the sensors.
As a practical implementation manner, the sensor configured in the downhole "open hole section" diameter monitoring device may specifically be a Linear displacement sensor (LVDT), where two ends of the Linear displacement sensor are in contact with the surrounding rock of the target tubular column, that is, the length direction of the Linear displacement sensor is perpendicular to the tubular wall and is in the same straight line with the diameter that can be monitored, and during the peristaltic contraction process of the target tubular column, the surrounding rock contacting the target tubular column causes the length of the Linear displacement sensor to change correspondingly, which is caused by the extrusion of the surrounding rock on two ends of the Linear displacement sensor, so that the Linear displacement sensor can record the change of its own length, and obtain the diameter monitoring result.
In addition, in practical application, the diameter monitoring device of the downhole naked eye section can be configured with sensors of types other than the linear displacement sensor, such as an ultrasonic sensor, an infrared sensor and even an image sensor, and the factors such as application cost, application environment and the like can be considered according to monitoring requirements.
The diameter monitoring result obtained by monitoring the diameter monitoring device in the downhole open hole section is a primarily monitored diameter result, or the diameter monitoring result collected by the diameter monitoring device in the downhole open hole section is original data, and then the original data is transmitted to the remote data analysis terminal for final analysis, so that a final target diameter monitoring result which can be output is obtained.
Under the arrangement, more data processing can be carried out to the ground remote data analysis terminal as much as possible, so that for the underground diameter monitoring device of the open hole section, the related data processing scale is smaller, and the requirements on software and hardware are reduced.
And under the condition that the diameter monitoring result acquired by the downhole naked eye section diameter monitoring device is original data, the downhole naked eye section diameter monitoring device can acquire the diameter monitoring result at the naked eye section at different time points, and the remote data analysis terminal can analyze the diameter shrinkage result of the target tubular column integrally according to the diameter monitoring results acquired at a plurality of different time points, so that the diameter shrinkage result acquired by the remote data analysis terminal has higher analysis precision.
The diameter monitoring device of the downhole naked eye section is continuously concerned, in practical application, the number of the diameter monitoring devices of the downhole naked eye section is more than one, and the diameter monitoring devices of the downhole naked eye section can be distributed at a target pipe column according to preset distribution density, diameter monitoring of different depth positions of the naked eye section is completed, and the preset distribution density is specifically set in density units such as unit interval, unit depth or unit number.
Obviously, the preset deployment density of the downhole open hole section diameter monitoring device can obtain a balance between the deployment cost and the monitoring range in actual operation, and the adaptive deployment density is determined by combining density units such as unit spacing, unit depth or unit number.
Meanwhile, the working pressure and the service life of the downhole 'open hole section' diameter monitoring device are considered, in order to avoid high-intensity work, the monitoring time interval of the downhole 'open hole section' diameter monitoring device can be set to be 10 minutes, the monitoring requirement is met, the working pressure can be reduced, and the long service life of the downhole 'open hole section' diameter monitoring device is guaranteed.
Of course, the monitoring time interval may also be 3 minutes, 5 minutes, 20 minutes, 30 minutes, and the like, and may be specifically adjusted according to actual needs.
Secondly, to the transmission line of configuration between "bore hole section" diameter monitoring devices in the pit and the paperless record appearance data storage device, this application specifically adopts for wired transmission line, promptly, accomplishes the transmission of diameter observation result and relevant work order through the communication cable, so in the underground environment of salt cavern gas storage, has reliable and stable effect of work.
It can be understood that the paperless recorder data storage device is mainly responsible for receiving, storing and forwarding the diameter observation result.
As an example, the paperless recorder data storage device can integrate multiple functions of data measurement, display, processing, operation, alarm, report form recording and the like, a high-speed and high-performance 32-bit correx-M4 microprocessor is adopted inside, a circuit board is subjected to three-prevention coating treatment of corrosion prevention, moisture prevention and dust prevention, an instrument power supply has strong anti-interference capability, external harmonic interference can be effectively inhibited, the stability of the whole machine is greatly improved, 48M bytes Flash is adopted in the device in the early spring, a USB interface and other equipment local transmission data are supported outside, power failure protection is supported at the same time, all data are stored in a Flash storage, all historical data and configuration parameters are prevented from being lost due to power failure, and power is supplied by a lithium battery after the power failure.
The communication device, i.e. the Data Transfer Unit (DTU), on which the specific forwarding of the diameter observation depends is located between the paperless logger Data storage device located on the well and the remote Data analysis terminal located remotely.
As another example, the data remote transmission apparatus may operate in a manner of implementing bidirectional transparent data transmission from a serial port to a network, supporting a network transparent transmission mode, having the characteristics of high speed and low delay, and implementing functions of automatically positioning, remotely configuring DTU parameters, remotely upgrading DTU firmware, monitoring terminal device data, cloud transparent transmission of relay terminal device data, DTU offline alarm, tracking DTU position, monitoring signal quality, monitoring data flow, managing a SIM card, and the like, and in the network transparent transmission mode, it may transmit data to a designated device.
As a practical implementation manner, the communication module configured in the data remote transmission device is specifically a 4G communication module or a 5G communication module, and compared with the method of using other devices to forward data, for example, the data remote transmission device sends data to a device in a manner of bluetooth, Wireless Fidelity (Wi-Fi), zigbee (zigbee), and the like, and then forwards the data to a designated device, the data remote transmission device can directly complete communication and internet surfing through the self-configured 4G communication module or 5G communication module, and forwards the data to the designated device.
For example, the network transmission of the data remote transmission device can be completed by depending on a 4G traffic card (corresponding to a 4G communication module).
It can be understood that, in practical application, the data remote transmission device can directly send the diameter monitoring result to the remote data analysis terminal, so as to prompt the remote data analysis terminal to perform corresponding analysis processing; alternatively, it may be sent to a remote data analysis terminal in an indirect manner.
That is, in the present application, as another practical implementation manner, the monitoring system may further include a cloud server, and the paperless recorder data storage device transmits the diameter monitoring result to the cloud server through a communication module configured by the data remote transmission device, so that the remote data analysis terminal downloads and analyzes the diameter monitoring result from the cloud server.
It can be understood that if upload the diameter monitoring result to the cloud ware, by cloud ware storage diameter monitoring result, and carry out the corresponding seeking of diameter monitoring result, download service, can impel in practical application, remote data analysis terminal side can be convenient change equipment or change the account number of logging in, reach better data transmission effect promptly, data storage effect, more can reach better data and look up the effect, conveniently adjust remote data analysis terminal under different situation, and carry out the analysis of diameter monitoring result on remote data analysis terminal.
The remote data analysis terminal can be different types of terminal equipment such as a desktop computer, a notebook computer, an all-in-one computer, a smart phone, a tablet Personal computer, a Personal Digital Assistant (PDA) and the like, and at the remote data analysis terminal side, a worker can check and control the work of the monitoring system provided by the application through human-computer interaction and can check the analysis result of the remote data analysis terminal on the received diameter monitoring result.
In the specific analysis processing of the remote data analysis terminal, as another example, if the diameter monitoring result is obtained by monitoring from downhole "open hole section" diameter monitoring devices configured at different positions of the target tubular column, the remote data analysis terminal may further analyze the diameter monitoring result obtained by monitoring the downhole "open hole section" diameter monitoring devices configured at different positions to obtain a plurality of sub-diameter shrinkage results, and then fuse the plurality of sub-diameter shrinkage results to obtain the target diameter shrinkage result.
That is to say, the sub-diameter shrinkage results corresponding to each downhole open hole section diameter monitoring device are analyzed, and then the sub-diameter shrinkage results corresponding to the downhole open hole section diameter monitoring devices are integrally fused to obtain the final target diameter shrinkage result capable of being output.
It can be understood that, under the setting, compared with the method of directly analyzing and fusing all diameter monitoring results on the whole, the method analyzes and fuses corresponding sub-diameter shrinkage results for different downhole open hole section diameter monitoring devices, and balances the proportion of each downhole open hole section diameter monitoring device in the position or the specific gravity of the device monitoring result to fuse the whole target diameter shrinkage result, so that the method has the characteristics of flexibility and fineness in the aspects of analysis effect and analysis precision, and can bring higher analysis precision.
Secondly, on the basis of analyzing and monitoring the diameter shrinkage result of the naked eye section, the corresponding alarm event can be configured according to the practical application requirement so as to send an alarm to related equipment or workers in the first time, so that the diameter shrinkage result of the naked eye section is prompted to have abnormal or emergency situations, and the diameter shrinkage result of the naked eye section needs to be checked, maintained and the like in time.
Namely, after the diameter shrinkage result of the target pipe column is obtained through analysis, when the diameter shrinkage result of the target pipe column meets the alarm condition, the remote data analysis terminal outputs an early warning.
The early warning condition includes an alert value set based on consideration factors such as contraction efficiency or contraction amplitude.
