Technical Field

[0001] The invention relates to the field of well logging downhole bus transmission, in particular to a well logging storage method, system, terminal and medium accessed by a token ring network. Background Art

[0002] Geophysical logging (referred to as logging) is an important technology in the process of oil production. In the process of exploring and exploiting underground mineral deposits such as oil and natural gas, the basic principles of physics are used, and advanced instruments and equipment are used to detect the physical property parameters (electricity / acoustic / radioactivity) of the well wall medium, and evaluate the lithology, physical properties (porosity, permeability), electrical properties, and oil content (four-property relationship) of the reservoir. The logging system mainly completes the measurement and analysis of various physical properties of the underground formation. It is a data-centric control system that realizes the functions of logging information collection, transmission, processing and quality control through a certain transmission medium. It is the material carrier of all logging information application technologies, including system hardware and system software. Among them, downhole instrument data storage and high-speed and high-reliability data transmission between the ground system are key technologies that need to be broken through in the application of the logging system, which puts forward higher requirements for the downhole instrument bus. At present, downhole instruments mostly use DTB bus, Ethernet bus, and CAN bus. However, the bus mode used by various logging systems cannot select data collection according to demand, but needs to collect all data at one time according to the set transmission rate. Sometimes, due to the limitations of transmission distance and transmission speed, the amount of received data is too large and the real-time storage is too large. Summary of the invention

[0003] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a logging storage method, system, terminal and medium using a token ring network access to solve the technical problems in the prior art of large amount of downhole instrument data, complex storage method and low storage efficiency.

[0025] 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.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0027] The purpose of the present invention is to provide a well logging storage method, system, terminal and medium using a token ring network access to solve the technical problems of large amount of downhole instrument data, complex storage method and low storage efficiency in the prior art.

[0028] See also Figure 1 In one embodiment of the present invention, a method for storing well logging data using a token ring network is provided, comprising the following steps:

[0029] Step 1, obtaining information of multiple downhole instruments, determining cyclic communication connections of multiple downhole instruments, and forming a token ring network bus;

[0030] Specifically, the address information of multiple downhole instruments is obtained by the host computer through the downhole telemetry instrument.

[0031] Step 2, setting multiple downhole instruments as corresponding nodes, numbering the multiple nodes, and setting node access priorities according to the numbers;

[0032] Specifically, corresponding nodes are set for multiple downhole instruments, and multiple nodes are numbered in sequence along the token ring network bus, one of the nodes is set as the first node, and the node access priority is set on the first node along the token ring network bus.

[0033] The node access priority is set in a unidirectional manner along the token ring network bus in sequence from the first node access to the last node access.

[0034] Step 3: The token receives the access instruction and accesses the nodes in sequence according to the node access priority. After determining the node to store the real-time collected data, it passes it to the next node for data storage until all token accesses are completed.

[0035] Specifically, the token accesses nodes in sequence according to the node access priority, obtains the node addresses of the previous node and the next node in sequence, accesses the nodes in sequence along the token ring network bus, and stores the real-time collected data through the node feedback information.

[0036] The token performs unidirectional access to nodes along the token ring bus, and deletes the information of the previous node after visiting the previous node.

[0037] The token ring network bus in the present invention includes a host computer, a network cable, a coaxial cable, a downhole telemetry instrument, and a plurality of downhole instruments. Each downhole instrument is set as a node to realize multi-node unidirectional access of the token.

[0038] The host computer refers to a computer or single-chip microcomputer that can directly send operation instructions. It generally provides a user operation interactive interface and displays transmission data to the user. Here it is a PC.

[0039] Downhole telemetry refers to the cable telemetry sub, which is a unified data transmission system between all downhole instruments and the ground computer logging system. Its main function is to collect downhole data and transmit it to the ground.

[0040] The downhole instruments should be cable logging series instruments.

[0041] The token in the present invention is a 3-byte special frame, and the data frame is released after receiving the data frame sent by the node.

[0042] Example

[0043] according to Figure 2As shown, taking three parameters, inclination, wellbore, lateral, acoustic wave, and induction downhole instruments as examples, it includes a host computer, a network cable, a coaxial cable, a downhole telemetry instrument, and several downhole instruments. Since a variety of combinations can be used for downhole instrument logging operations, it is not limited to the combination of the instruments listed above, but the overall data transmission principle is the same. Each downhole instrument acts as a node to achieve multi-node unidirectional access to the token. The logging storage method includes the following steps:

[0044] S1, select a computer as the host computer, and connect each downhole instrument. There is no requirement for the number of downhole instrument connections, and multiple nodes can be set for token access.

[0045] S2, set the access priority of each instrument node according to the requirements, and define each instrument as node 1, node 2, and so on in the order of priority. Use the set nodes to create a virtual ring.

[0046] S3, the host computer sends a command, first node 1 decides whether to store the real-time collected data, and can store the current node data according to demand. If the data does not need to be stored, the token is passed to the next node.

[0047] S4, repeat S3, and continue to unidirectionally transfer to the next node for data storage until all token accesses are completed as required. The data flow is unidirectional in the direction of token transfer; in order to prevent the token from circulating infinitely, once it has completed its purpose, it will be deleted from the network to ensure efficient data transmission.

[0048] In summary, the present invention provides a logging storage method using a token ring network for access, in which downhole instruments are used as nodes in a virtual ring, and serial numbers are defined for each node according to a custom priority order. Based on the token access characteristics, each node is accessed in sequence starting from the first node and a host computer command is received to execute whether to store the current real-time collected data. This real-time access and real-time storage method can greatly improve data transmission and storage efficiency.

After determining the node to store real-time collected data, it passes it to the next node for data storage until all token accesses are completed.
