[0002] The Beidou-2 satellite navigation system (BD2, Beidou-2) is a global satellite navigation system independently developed by China. As of the end of 2012, there are currently 14 satellites serving the Asia-Pacific region, including 5 GEO satellites, 5 IGSO satellites and 4 MEO satellites. Among them, the Beidou-2 5 GEO satellites provide short message communication function, and other satellites provide navigation and positioning function. Among the 5 GEO satellites, each satellite contains 2 independent beam signals, i.e. a total of 10 independent beam signals provide short message communication service. The data remote transmission technology based on Beidou short message is also gradually applied in the oil and gas industry.

It should be noted that, as long as no conflict exists, the various embodiments of the present invention and the various features of the embodiments can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.

[0028] In addition, the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in a different order than here.

[0029] Beidou-2 is a global satellite navigation system developed independently by China. As of the end of 2012, there are 14 satellites serving the Asia-Pacific region, including 5 GEO satellites, 5 IGSO satellites and 4 MEO satellites. Among them, the 5 GEO satellites of Beidou-2 provide short message communication function, and other satellites provide navigation and positioning function. Among the 5 GEO satellites, each satellite contains 2 independent beam signals, i.e. a total of 10 independent beam signals provide short message communication service. The data remote transmission technology based on Beidou short message is also gradually applied in the oil and petrochemical industry. Due to the remote geographical environment of the well site, the transportation and communication conditions are restricted, and the commonly used communication means in daily life such as 3G / 4G network and optical fiber have high cost for laying and maintenance in remote well sites. At present, commercial satellites are often used for well site data remote transmission, but the cost is high, so the research on data remote transmission based on Beidou system is carried out to reduce the cost while ensuring the quality of data remote transmission.

[0030] Although the existing Beidou short message transceiving technology can be applied to various scenarios, there are still the following problems: first, although the existing implementation method of Beidou short message multi-card user machine can improve the data sending frequency, the sending frequency is deeply coupled with the number of terminal Beidou cards, and the data sending frequency cannot be directly set, so the flexibility is poor; second, by using the same shared terminal by multiple users to reduce the procurement and operation and maintenance cost, the use efficiency of Beidou short message satellite terminal is improved, but the user does not have the control right and ownership of the terminal, and the stability and safety of data remote transmission cannot be guaranteed; third, the multi-card automatic switching Beidou short message communication gateway does not have the function of high-frequency data sending through the configuration of multiple Beidou cards for short message sending stability.

[0031] In addition, although the existing Beidou short message communication technology can be applied in oil and gas areas, it is limited to the use of Beidou single communication module, the data sending frequency is 60 seconds each time, and each short message can only accommodate 79 bytes, which cannot meet the real-time data transmission demand of the well site at present.

[0032] Therefore, in order to solve one or more of the above technical problems, the present application proposes a well site real-time data remote transmission system and an implementation method thereof. The system comprises a field end device arranged at a drilling site and a remote end device arranged at a well site background. The field end device comprises a first Beidou terminal for realizing short message communication and navigation positioning, and a field control device. The field control device can obtain a transmission frequency set by a user and convert the transmission frequency into a short message sending frequency. Then, the well site messages that need to be remotely transmitted in real time at the drilling site and meet the Beidou short message format are sent to the remote end through the first Beidou terminal via satellite signals according to the short message sending frequency. In this way, the well site real-time data remote transmission system based on the Beidou short message technology can provide a low-cost transmission method for data remote transmission of remote well sites, and can control the data transmission frequency to realize real-time sending and receiving of well site data.

[0033] Figure 2 is a specific structure schematic diagram of the well site real-time data remote transmission system of the embodiment of the present application. The present application provides a well site real-time data remote transmission system (hereinafter referred to as "remote transmission system"). As shown in Figure 2 , the remote transmission system comprises a field end device 100 and a remote end device 300. The field end device is arranged at a drilling site, and the remote end device is arranged at a background end of the drilling site.

[0034] Figure 1 is a whole structure schematic diagram of the field end device for the well site real-time data remote transmission system of the embodiment of the present application. As shown in Figure 1 , the field end device 100 at least comprises a first Beidou terminal 101 arranged at a drilling site and a field control device 102. The first Beidou terminal 101 and the field control device 102 are connected through a serial port for bidirectional communication.

[0035] In the embodiment of the present application, the first Beidou terminal 101 adopts a Beidou multi-card terminal device. The first Beidou terminal 101 is used for realizing short message communication and RNSS navigation positioning. The first Beidou terminal 101 comprises a Beidou multi-frequency antenna, a radio frequency module, a baseband processing, a first Beidou card array and a main control board, and can realize high-frequency short message communication and RNSS navigation positioning. The first Beidou array comprises at least one main Beidou card and a plurality of auxiliary Beidou cards. The main Beidou card can be used for receiving information and sending information. The auxiliary Beidou card is used for sending information.

[0036] In one embodiment, the first Beidou terminal 101 internally supports a maximum of 17 Beidou cards, one of which is a main card that can be used for receiving information and sending information, and the remaining 16 are auxiliary cards that are only used for sending information.

[0037] The field control device 102 is connected to the first Beidou terminal 101 and is used to control the first Beidou terminal 101. The field control device 102 is also used to obtain a transmission frequency set by a user (e.g., a staff member at the well site), and then convert the transmission frequency into a short message transmission frequency. According to the currently generated short message transmission frequency, the well site message that needs to be transmitted remotely in real time from the drilling site is sent to the remote end 200 via the first Beidou terminal 101 in the form of a Beidou short message. In an embodiment of the present invention, the transmission frequency is a data transmission (transmission) frequency set by the well site user to meet the real-time data transmission requirements of the well site. The short message transmission frequency is the information (short message) transmission frequency that can actually be achieved by the transmission frequency under the device configuration conditions of the first Beidou terminal 101.

[0038] The field control device 102 is a server connected to the first Beidou terminal 101, with a built-in software system. By controlling the Beidou multi-card terminal, the real-time data of the well site is sent and received in the form of Beidou short messages, realizing the remote transmission function of the real-time data of the well site at a fixed frequency (short message sending frequency) between the Beidou terminals corresponding to the field end and the remote end.

[0039] like Figure 1 As shown, the field control device 102 comprises at least: a front-end display module 201, a format conversion module 202 and a data remote transmission module 203. In the field control device 102, each module is developed for two scenario states: (message) sending and (message) receiving.

[0040] The following describes the implementation principle and functional structure of the field control device 102 in the message sending state.

[0041] Front-end display module 201 is used to obtain the transmission frequency input by the user during message transmission. In this embodiment of the present invention, front-end display module 201 is preferably a human-computer interaction interface device that allows the input of the transmission frequency of real-time wellsite data and applies the input transmission frequency to the high-frequency data remote transmission module 203.

[0042] The format conversion module 202 is used to collect real-time wellsite data from the drilling site when the message is sent, and to perform data compression, Beidou message format conversion and encryption on the real-time wellsite data obtained in real time to form a corresponding wellsite message, thereby transmitting the real-time generated wellsite message to the data remote transmission module 203.

[0043] In the format conversion module 202, on the one hand, the well site real-time data to be transmitted remotely is collected in real time, and each well site real-time data collected in real time is processed in a series of (format conditions) so that each well site real-time data meets the format conditions of being sent out by the Beidou multi-card terminal. The well site real-time data includes but is not limited to well depth, rotation speed, drilling pressure, total pool volume, inlet flow, outlet flow, inlet temperature and outlet temperature and the like.

[0044] In addition, in the embodiment of the present application, the format condition processing is to first compress each well site real-time data to meet the length limit of 79 bytes of short message, so as to meet the Beidou terminal sending standard, and then sequentially perform Beidou message protocol format conversion processing and Beidou protocol processing on the compressed data, so as to obtain a corresponding well site message for each well site real-time data.

[0045] The data remote transmission module 203 is connected with the front-end display module 201 and the format conversion module 202 respectively. The data remote transmission module 203 is used to buffer the well site messages to be transmitted remotely by using information queue technology in the message sending state, so as to transmit the well site messages to be sent to the first Beidou terminal 101 at a short message sending frequency generated based on the current transmission frequency.

[0046] On the one hand, the data remote transmission module 203 needs to obtain the transmission frequency transmitted from the front-end display module 201, and then convert the transmission frequency into a short message sending frequency. The conversion of the transmission frequency into the short message frequency is performed by using the following expression:

[0047] F = MAX (T / N, U) (1)

[0048] Wherein, F represents the short message sending frequency, T represents the frequency of sending a short message by a single Beidou card (for example: 60 seconds), N represents the number of Beidou sub-cards accessed in the message sending state, and U represents the transmission frequency. In one embodiment, when 16 sub-cards are fully accessed to the field control device, the short message sending frequency of the current Beidou multi-card terminal (the first Beidou terminal 101) is about 4 seconds / time. In this way, the first Beidou terminal 101 in the embodiment of the present application uses the restriction of the device sending frequency condition (T / N) related to the configuration condition of the Beidou terminal device to meet the transmission frequency required by the user to realize the remote transmission function of the well site real-time data by the way of multi-card rotation sending Beidou short message data packet, and this sending frequency limiting method reduces the deep coupling between the sending frequency and the number of Beidou cards of the multi-card user machine, and the data remote transmission frequency can be directly and flexibly set.

[0049] In addition, after the short message sending frequency is generated, the data remote transmission module 203 in the embodiment of the present application also uses information queue technology to cache the well site messages that need to be transmitted to the remote end in real time. In the data remote transmission module 203, a sending information cache space with a preset capacity is configured. In the sending information cache space, well site messages based on different data collection time points are stored. In the message sending state, the data remote transmission module 203 will cache the real-time well site messages to be sent in a queue, and send the well site messages out of the queue at the current generated short message sending frequency (preferably, at the sending frequency set by the user) to the first Beidou terminal 101 through the serial port (such as the RS232 serial port).

[0050] The implementation principle and functional structure of the field control device 102 in the message receiving state will be described below.

[0051] The data remote transmission module 203 is also used to receive feedback messages transmitted from the remote end through the first Beidou terminal 101 in the message receiving state, and uses information queue technology to cache the received feedback messages. In the data remote transmission module 203, a receiving information cache space with a preset capacity is configured. In the receiving information cache space, feedback messages based on different data receiving time points are stored. In the message receiving state, the feedback messages received from the first Beidou terminal 101 are cached in the message queue, and then each feedback message in the queue waits to be sent out in turn, so as to be used after being decoded.

[0052] The format conversion module 202 is also used to analyze and decompress the cached feedback messages in the message receiving state, so as to obtain the feedback information sent by the well site background to the field.

[0053] On the one hand, the format conversion module 202 will collect the feedback messages transmitted from the remote end in real time, and will also perform a series of (analysis condition) processing on each feedback message collected in real time, so that each feedback message meets the analysis of the field control device server. In addition, in the embodiment of the present application, the analysis condition processing is to first analyze the Beidou protocol of each feedback message, and then perform decompression processing, so as to output the feedback information that the remote end needs to send to the field. The feedback information is the instructions and / or data related to parameter configuration, device control, early warning and alarm prompt, etc. that the remote end needs to control and manage the field end.

[0054] At this time, the front-end display module 201 responds and / or displays the restored feedback information in the message receiving state.

[0055] Reference Figure 2The remote terminal device 300 at least comprises a second Beidou terminal 301 and a remote control device 302 arranged at a remote background of the drilling site.

[0056] The second Beidou terminal 301 adopts a Beidou multi-card terminal device. The second Beidou terminal 301 is used to realize short message communication and RNSS navigation positioning. The second Beidou terminal 301 comprises a Beidou multi-frequency antenna, a radio frequency module, a baseband processing, a second Beidou card array and a main control board, and can realize high-frequency short message communication and RNSS navigation positioning and other functions. The second Beidou array comprises at least one main Beidou card and multiple auxiliary Beidou cards. In the embodiment of the present application, since the first Beidou terminal 101 and the second Beidou terminal 301 are similar in structure and function, the present application does not repeat the structure and function of the second Beidou terminal 301.

[0057] The remote control device 302 is used to acquire the well site message transmitted from the field terminal through the second Beidou terminal 301, and restore the well site message. In the embodiment of the present application, since the internal structure, the connection mode of each module and the function of each module of the remote control device 302 are similar to those of the field control device 301, the specific structure and internal function of the remote control device 302 are not repeated.

[0058] Further, the remote control device 302 is also used to receive the well site message transmitted from the field terminal according to the receiving process involved in the similar message receiving state of the field control device 301, restore each received well site message, and output the original well site real-time data, so that the restored original well site real-time data is displayed in real time by the front-end display module in the remote control device 302 and is recorded in the database. In addition, the remote control device 302 is also used to generate a feedback message according to the feedback information required to be sent to the field terminal according to the sending process involved in the similar message sending state of the field control device 301, and then send the feedback message to the field terminal at a short message sending frequency generated based on the transmission frequency input by the user.

[0059] Figure 3 The transmission principle of the well site message in the well site real-time data remote transmission system of the embodiment of the present application is shown in the figure. Figure 3As shown, when sending well site messages, the well site real-time data in the field control device is compressed and protocol encrypted by the format conversion module 202, and the well site real-time data has the condition of being sent out by the Beidou multi-card terminal. The well site real-time data compressed and protocol adapted enters the data high-frequency remote transmission module 203 for buffering. The user can set the transmission frequency on the front-end display interface, and the data high-frequency remote transmission module 203 will send the well site real-time data in the form of Beidou short message to the Beidou multi-card terminal at the frequency. When receiving the well site message, the message received by the Beidou multi-card terminal is buffered in the data high-frequency remote transmission module, and then protocol decrypted by the Beidou protocol adaptation module (format conversion module), and displayed on the front-end display interface and stored in the warehouse.

[0060] In this way, the well site real-time data remote transmission system of the present application sends and receives the well site real-time data in the form of Beidou short message through the multi-card terminal respectively arranged at the well site and the background, realizes the fixed frequency well site real-time data remote transmission between the two Beidou terminals, and thus ensures the point-to-point short message communication between the field and the background.

[0061] The following provides a specific example of the well site real-time data remote transmission system described in the present application:

[0062] When performing real-time data remote transmission for remote well sites, one industrial computer is arranged at the well site, and the industrial computer has well site real-time data; another networkable server is arranged at the remote end, which can store the received server or perform subsequent operation. The deployment points of the present application are as follows:

If the user inputs the frequency U<F, the system will prompt the user on the front-end display interface.

[0065] ③For each well site real-time data, first through the well site real-time data Beidou protocol adaptation module compression and protocol adaptation processing, the data has the conditions of being transmitted by Beidou multi-card terminal. After compression and protocol adaptation processing, the data enters the data high frequency remote module to transmit data at a frequency F.

[0066] ④The receiving end receives the data and puts it into the data high frequency remote module for buffering, and then sequentially passes through the well site real-time data Beidou protocol adaptation module for protocol analysis and decompression. After obtaining the original well site real-time data, sequentially perform warehousing, and display the data on the front-end display page.

[0067] On the other hand, based on the above-mentioned well site real-time data remote transmission system, the embodiment of the present application also provides a method for realizing remote transmission of well site real-time data (hereinafter referred to as "remote transmission implementation method"), which is realized by the above-mentioned well site real-time data remote transmission system. Figure 4 is the step diagram of the method for realizing remote transmission of well site real-time data of the embodiment of the present application.

[0070] Step S402, converting the currently set transmission frequency into a short message sending frequency, and sending the well site messages that need to be remotely transmitted in real time in the form of Beidou short messages through the first Beidou terminal set in the drilling site to the remote end according to the short message sending frequency;

[0071] Step S403, acquiring the currently transmitted well site messages by the remote end through the second Beidou terminal set in the drilling remote background, and restoring the well site messages.

[0072] Further, the above-mentioned short message sending frequency is generated by using the following expression:

[0073] F = MAX (T / N, U)

[0074] Wherein, F represents the short message sending frequency, T represents the frequency of sending short messages by a single Beidou card, N represents the number of Beidou sub-cards accessed in the message sending state, and U represents the transmission frequency set by the user.
