Description

Technical Field

[0001] This application relates to the technical field of oil extraction, and in particular to an addressing system for smart probes. Background Technology

[0002] For oil extraction, well logging operations are becoming increasingly difficult, requiring different working methods to meet the needs of normal extraction operations.

[0003] In related technologies, logging operations require retrieving the drill string after drilling is complete, and then lowering it using a cable and gas to complete the logging. However, this method affects drilling efficiency. To reduce the impact on drilling efficiency, drill string logging technology has been developed.

[0004] Through-the-string logging technology allows logging to be performed without removing the drill string. However, the internal diameter of the drill string necessitates a smaller outer diameter for the instrument, which in turn limits the sensor size. Wellbore coverage is a crucial factor during logging, and to maximize coverage, a multi-probe approach is employed. Given the multiple probes, a critical challenge is ensuring that the probes automatically detect their location when replacement is needed. Utility Model Content

[0005] In order to enable the probe to automatically obtain address information, this application provides an addressing system for intelligent probes.

[0006] The addressing system for smart probes provided in this application adopts the following technical solution:

[0007] An addressing system for a smart probe includes an addressing module for connecting to the smart probe and for changing the feedback level of the smart probe to enable the smart probe to acquire address information.

[0008] By adopting the above technical solution and utilizing the addressing module, when multiple smart probes are connected to this system, the addressing module provides feedback to the smart probes, enabling them to acquire address information. Once the smart probes acquire the address information, they can correlate the detection data with the corresponding information. Furthermore, even if a smart probe is replaced, it can automatically obtain the address information based on its installation location, eliminating the need for manual settings and improving convenience.

[0009] Optionally, the addressing module includes address lines, which are divided into A address lines and B address lines. The addressing module also includes N wiring sub-modules, each of which is connected to N-1 address lines, and the number of A address lines among the N-1 address lines connected to each wiring sub-module is different; where N≥3 and N is an integer.

[0010] By adopting the above technical solution, multiple smart probes are connected. The number of A address lines connected to each wiring submodule is different, while the total number of address lines connected to each wiring submodule is the same. Due to the different number of A address lines, the feedback level is different. Based on this, the address information of the smart probe can be determined, that is, it can be determined which smart probe sent the data.

[0011] Optionally, address line A is grounded, and address line B is left floating.

[0012] By adopting the above technical solution, address line A is grounded. After the smart probe outputs a high level, the grounding will cause this pin to switch to a low level, resulting in a high level feedback. When address line B is left floating, the feedback level is also high. Based on this, the smart probe can obtain address information.

[0013] Optionally, the addressing module includes address lines, which are divided into A address lines and B address lines. The A address lines are grounded, and the B address lines are left floating. The addressing module also includes three wiring sub-modules, which are a first wiring sub-module, a second wiring sub-module, and a third wiring sub-module. The first wiring sub-module connects two A address lines, the second wiring sub-module connects one A address line and one B address line, and the third wiring sub-module connects two B address lines.

[0014] By adopting the above technical solution and using two address lines, the address of each wiring submodule can be determined. The intelligent probe can obtain the address information by feeding back the voltage level. Furthermore, the position and address of the wiring submodule remain unchanged; even if the intelligent probe is moved, the address information obtained will still be the address information of the current position.

[0015] Optionally, the wiring submodule is a plug.

[0016] By adopting the above technical solution and utilizing connectors, the smart probe can be easily installed and removed, thus improving convenience.

[0017] Optionally, the A address line connected to the second wiring submodule is connected to the A address line connected to the first wiring submodule, and the B address line connected to the second wiring submodule is connected to the B address line connected to the third wiring submodule.

[0018] By adopting the above technical solution, the connection method of shorting between the same address lines can reduce the amount of connection wires used, reduce costs, and also reduce the thickness of the wire harness to a certain extent.

[0019] Optionally, the addressing module includes address lines, which are divided into A address lines and B address lines. The A address lines are grounded, and the B address lines are connected to a high-level output terminal. The addressing module also includes three wiring sub-modules, namely a first wiring sub-module, a second wiring sub-module, and a third wiring sub-module. The first wiring sub-module is connected to two A address lines, the second wiring sub-module is connected to one A address line and one B address line, and the third wiring sub-module is connected to two B address lines.

[0020] By adopting the above technical solution, the address line is grounded or can provide a high level to provide level feedback to the smart probe, so that the smart probe receives different feedback levels, thereby obtaining address information.

[0021] Optionally, the A address line connected to the second wiring submodule is connected to the A address line connected to the first wiring submodule, and the B address line connected to the second wiring submodule is connected to the B address line connected to the third wiring submodule.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Utilizing an addressing module, when multiple smart probes are connected to this system, the module provides feedback voltage to the smart probes, enabling them to acquire address information. Once the smart probes obtain the address information, they can correlate the detection data with the corresponding information. Furthermore, even if a smart probe is replaced, it can automatically obtain the address information based on its installation location, eliminating the need for manual settings and improving convenience.

[0024] 2. Connect multiple smart probes, and each wiring submodule has a different number of A address lines connected to it, while the total number of address lines connected to each wiring submodule is the same. Due to the different number of A address lines, the feedback level is different. Based on this, the address information of the smart probe can be determined, that is, it can be determined which smart probe sent the data. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] Example 1

[0030] This application discloses an addressing system for smart probes. (Refer to...) Figure 1 An addressing system for smart probes includes an addressing module 1, which is used to connect to multiple smart probes. By changing the feedback level of the smart probes, the smart probes can obtain address information.

[0031] Using addressing module 1, the smart probe can automatically acquire address information, determine its location, and thus associate the detection data with the smart probe. Furthermore, even if the smart probe is replaced or its position is interchanged, it can still automatically acquire the address information of its installation location, improving convenience.

[0032] Specifically, the addressing module 1 includes address lines 2, which are A address lines and B address lines respectively. The addressing module 1 also includes N wiring sub-modules 3. In this embodiment, the wiring sub-modules 3 can be connectors. Each wiring sub-module 3 is connected to N-1 address lines 2, and the number of A address lines among the N-1 address lines 2 connected to each wiring sub-module 3 is different. Wherein, N≥2, and N is an integer; the number of A address lines connected to each wiring sub-module 3 is different, and the number of A address lines can be zero; the A address lines are grounded, and the B address lines are left floating.

[0033] After connecting the smart probe to the wiring submodule 3, the smart probe pulls the level of the pin connected to the wiring submodule 3 high and detects whether there is a change in the pin level. If there is a change, it can be known that the pin is grounded, that is, that the pin is connected to address line A. By knowing the number of connected address lines A, the smart probe can know the number of connected address lines B. Then, based on the number of both, it can know its own address.

[0034] Since the number of A address lines and B address lines connected to the wiring submodule 3 is fixed, even if the position of the smart probe is changed, the address is still fixed for a given wiring submodule 3. Therefore, even if the smart probe is replaced or the positions of the smart probes are interchanged, the address information at the fixed position will not be affected.

[0035] Reference Figure 2In this embodiment, N is determined to be three, meaning that the addressing module 1 includes three wiring sub-modules 3, namely, a first wiring sub-module 31, a second wiring sub-module 32, and a third wiring sub-module 33. The first wiring sub-module 31 connects to two A address lines, the second wiring sub-module 32 connects to one A address line and one B address line, and the third wiring sub-module 33 connects to two B address lines. The A address line connected to the second wiring sub-module 32 is connected to the A address line connected to the first wiring sub-module 31, and the B address line connected to the second wiring sub-module 32 is connected to the B address line connected to the third wiring sub-module 33.

[0036] When the smart probe outputs a high level, address line A is grounded, and the smart probe receives a low level feedback. Address line B is floating, so the smart probe receives a high level feedback. The address is obtained by using the high and low levels of the feedback.

[0037] For example, a high level feedback is represented as "1", and a low level feedback is represented as "0". As described above, the address of the first wiring submodule 31 is "00", the address of the second wiring submodule 32 is "01" or "10", and the address of the third wiring submodule 33 is "11".

[0038] Example 2

[0039] Reference Figure 2 Address line 2 is divided into address line A and address line B. Address line A is grounded and address line B is connected to the high-level output terminal. The first wiring module 31 connects two address lines A, the second wiring module 32 connects one address line A and one address line B, and the third wiring module 33 connects two address lines B.

[0040] Specifically, the A address line connected to the second wiring module 32 is connected to the A address line connected to the first wiring module 31, and the B address line connected to the second wiring module 32 is connected to the B address line connected to the third wiring module 33.

[0041] At this time, the smart probes connected to the first wiring submodule 31 all have low feedback levels, the smart probes connected to the second wiring submodule 32 have one low level and one high level feedback levels, and the smart probes at the third wiring submodule 33 all have high feedback levels.

[0042] The smart probe can determine the address by using different feedback levels.

[0043] The implementation principle of an addressing system for a smart probe according to an embodiment of this application is as follows: the addressing module 1 is used to enable the smart probe to know its current address, so that the platform or device used to receive the smart probe can determine which location of the smart probe sent the detection data.

[0044] To allow the smart probe to determine its own location, different feedback levels are provided to the smart probe via the wiring module 3, enabling the smart probe to obtain its own address and thus determine its location.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
