[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] A method for generating a logging service table is provided. Figure 1 and 2The specific embodiments of the present invention are described as follows:

[0037] Figure 1 The figure is a schematic diagram of the well logging downhole instrument bus design. The well logging downhole instrument bus of the present invention includes a controller 1, an Ethernet instrument bus 2, an RS485 bus 3, a well logging instrument 4, a well logging instrument 5, a well logging instrument 6, a well logging instrument 7 and a well logging instrument 8. The execution subject of the method of the present invention can be the controller 1. It should be noted that the number of well logging instrument strings is determined by the specific construction project and the number of instruments that can be simultaneously connected to the system, and the embodiment of the present invention does not limit it. In this embodiment, 5 are used as an example for explanation, which is not limiting.

[0038] It should be noted that the first node logging instrument in the embodiment of the present invention refers to the first logging instrument in the logging instrument string, such as logging instrument 4; the last node logging instrument refers to the last logging instrument in the logging instrument string, such as logging instrument 8.

[0039] The controller 1 performs duplex communication with logging instruments 4, 5, 6, 7, and 8 via the Ethernet instrument bus 2, controls the status of each logging instrument, and receives the data sent and collected by each logging instrument; the controller 1 also performs two-way communication with each logging instrument via the RS485 bus 3, and performs two-way communication between each logging instrument, to obtain the unique identification code reported by each logging instrument and the complete serial connection sequence data of the logging instruments. It should be noted that the controller 1 can be an independent functional module, or its functions can be integrated with the modules in the instruments of the ground system, for example, the corresponding functions of the present invention can be realized by adding communication hardware circuits and embedded codes in the telemetry unit.

[0040] The communication mode of the controller of the present invention to obtain the unique identification code of the logging instrument string can be flexibly set; it can be realized through RS485 bus 3 alone, that is, the first instruction instructs the current logging instrument to report its unique identification code to the previous logging instrument to achieve the above purpose. Figure 1 To explain:

[0041] like Figure 2 As shown, a unique identification code is defined for each instrument, which is represented by a 16-bit binary number, that is, composed of 2 bytes, wherein the high byte (8 to 15 bits) represents the type of instrument, and the low byte (0 to 7 bits) represents the serial number of the instrument; the type and serial number of the instrument can be uniquely determined through the unique identification code. It should be noted that the definition and number of bits of the unique identification code are not limited to the above Figure 2 As shown, it can be set according to the actual application scenario, and the number of bits and the definition of each bit can be set by yourself, as long as the type and serial number of the logging instrument can be uniquely identified, and the present invention does not limit it.

[0042] Therefore, the unique identification codes of the above-mentioned logging instruments 4, 5, 6, 7, and 8 are recorded as ID4, ID5, ID6, ID7, and ID8 respectively. Each logging instrument can report its own unique identification code and the unique identification code reported by the next-hop logging instrument to the previous-hop logging instrument through the RS485 bus 3. When the tail node logging instrument reports its own unique identification code, in addition to reporting its own unique identification code, it adds a suffix information to its own unique identification code and reports it to the previous-hop logging instrument as its own unique identification code. The suffix information is the identification information of the tail node logging instrument, that is, it identifies the tail node logging instrument as the last serial instrument in the above-mentioned logging instrument string, and there is no next-hop logging instrument in the subsequent string. For example, the previous logging instrument 7 of the tail node logging instrument 8 forwards the first instruction to the tail node logging instrument 8. The first instruction instructs the tail node logging instrument 8 to add an instrument identification code (i.e., suffix information) of all 0s at the end of its own unique identification code ID8, which is expressed in hexadecimal as "0x0000h", indicating that this is the last serial instrument in the logging instrument string.

[0043] Therefore, as described above, when the logging instrument string (4, 5, 6, 7, 8) is connected and the instrument is powered on, the logging instrument 8 reports "ID8+0x0000h" (a total of four bytes) to the logging instrument 7 through the RS485 bus 3, and the first instruction is also used to instruct the current logging instrument to insert its own unique identification code in front of the unique identification code reported by the next logging instrument as its current unique identification code; therefore, the logging instrument 7 reports "ID7+ID8+0x0000h" to the logging instrument 6 through the RS485 bus 3; similarly, the logging instrument 6 reports "ID6+ID7+ID8 +0x0000h" is reported to logging instrument 5 through RS485 bus 3; similarly, logging instrument 5 reports "ID5+ID6+ID7+ID8+0x0000h" to logging instrument 4 through RS485 bus 3; and so on, finally logging instrument 4 reports "ID4+ID5+ID6+ID7+ID8+0x0000h" to controller 1 through RS485 bus 3. Controller 1 identifies the type and serial number of each logging instrument according to the received information of "ID4+ID5+ID6+ID7+ID8+0x0000h" so as to automatically generate a logging service table. Of course, the controller 1 can also send the received "ID4+ID5+ID6+ID7+ID8+0x0000h" information to the ground system, such as the ground logging software system, and the ground system can identify the type and serial number of each logging instrument according to the "ID4+ID5+ID6+ID7+ID8+0x0000h" information, so as to automatically and accurately set the logging service table. So that the latest scale of each instrument corresponding to the number can be retrieved later, so as to achieve the purpose of controlling the instrument and collecting data. The logging data controlled and collected by the logging instrument is transmitted to the controller 1 through the Ethernet bus 2.

[0044] The communication mode of the controller of the present invention to obtain the unique identification code of the logging instrument string can be flexibly set; in addition to the above-mentioned single implementation through RS485 bus 3, that is, the first instruction instructs the current logging instrument to report its own unique identification code to the previous logging instrument to achieve the above purpose, the following is combined with Figure 1 Another way is described, that is, the first instruction instructs the current logging tool to report its unique identification code to the controller 1 to achieve the above purpose:

[0045] The controller 1 sends a first instruction to the logging instrument 4 of the head node through the RS485 bus 3, requesting to report a unique identification code.

[0046] Instrument 4 receives the command, reports "the command has been received" to controller 1 via RS485 bus 3, and reports "ID4+next hop logging instrument exists" to controller 1 via Ethernet instrument bus 2. Then, the first command (including the unique identification code ID4 of the current logging instrument) is forwarded to the next hop logging instrument 5 via RS485 bus 3.

[0047] The logging instrument 5 receives the first instruction, reports "the instruction has been received" to the logging instrument 4 at the previous hop through the RS485 bus 3, and reports "ID4+ID5+next hop logging instrument exists" to the controller 1 through the Ethernet instrument bus 2; then forwards the first instruction (including the current logging instrument's own unique identification code ID4+ID5) to the next hop logging instrument 6 through the RS485 bus 3. The first instruction is also used to instruct the current logging instrument to insert its own unique identification code after the unique identification code reported by the previous hop logging instrument as its current unique identification code.

[0048] The logging instrument 6 receives the first instruction, reports "the instruction has been received" to the logging instrument 5 on the previous hop through the RS485 bus 3, and reports "ID4+ID5+ID6+next hop logging instrument exists" to the controller 1 through the Ethernet instrument bus 2; then forwards the first instruction (including the current logging instrument's own unique identification code ID4+ID5+ID6) to the logging instrument on the next hop through the RS485 bus 3.

[0049] After receiving the first instruction, the logging instrument 7 reports "the instruction has been received" to the logging instrument 6 on the previous hop through the RS485 bus 3, and reports "ID4+ID5+ID6+ID7+the next hop logging instrument exists" to the controller 1 through the Ethernet instrument bus 2; then the first instruction (including the current logging instrument's own unique identification code ID4+ID5+ID6+ID7) is forwarded to the logging instrument 8 on the next hop through the RS485 bus 3.

[0050] After receiving the first instruction, the logging instrument 8 reports "the instruction has been received" to the logging instrument 7 of the previous hop through the RS485 bus 3. Since there is no next-hop logging instrument after the logging instrument 8, that is, the logging instrument 8 is a tail node logging instrument, even if the logging instrument 8 continues to forward the first instruction (including the current logging instrument's own unique identification code ID4+ID5+ID6+ID7+ID8), it will not receive the "instruction has been received" reply information reported by the next-hop logging instrument. Therefore, the logging instrument 8 reports "ID4+ID5+ID6+ID7+ID8+there is no next-hop logging instrument" to the controller 1 through the Ethernet instrument bus 2. Of course, as mentioned above, a suffix can also be added after the unique identification code of the current logging instrument as an identifier of "there is no next-hop logging instrument". Please refer to the above implementation method and it will not be repeated here.

[0051] Therefore, it can be seen from the above that the controller 1 obtains the unique identification code and connection sequence information of each logging instrument. The controller 1 can identify the type and serial number of each logging instrument based on the unique identification code and connection sequence information of each logging instrument, so as to automatically generate a logging service table. Of course, the controller 1 can also send the above information obtained to the ground system, such as the ground logging software system, and the ground system can identify the type and serial number of each logging instrument based on the above information, so as to automatically and accurately set the logging service table. So that the latest scale of the corresponding number of each instrument can be retrieved later, so as to achieve the purpose of controlling the instrument and collecting data. The logging data controlled and collected by the logging instrument is transmitted to the controller 1 via the Ethernet bus 2.

[0052] It should be noted that the specific implementation of the second method can also refer to the first method mentioned above and will not be repeated here.
