Description

Technical Field

[0001] This invention belongs to the field of oil and gas drilling measurement data transmission technology, and specifically relates to a multi-bus data fusion processing method and system based on a logging instrument. Background Technology

[0002] Microresistivity imaging logging technology is an important tool in oil exploration and development. By measuring the resistivity changes of the formation, information such as the formation structure, fracture distribution, and reservoir properties can be obtained, which helps geologists and engineers evaluate and develop oil and gas reservoirs.

[0003] Conventional microresistivity imaging logging instruments have certain limitations in their design, which are manifested in the following three aspects:

[0004] First, conventional microresistivity imaging logging instruments are designed as standalone units to acquire formation information. The acquired logging communication data, including formation information, needs to be transmitted to a surface system for processing and interpretation. Furthermore, the downhole controller does not autonomously control the instrument; all control commands are issued by the surface system. This single-mode data and command flow prevents conventional microresistivity imaging logging instruments from responding to changes during the measurement process in real time and avoids data interaction with other instruments in the instrument string. However, with the development of storage logging methods such as CNPC's FITS (Fit-in-the-Drill) and direct-drive logging, real-time monitoring and control of the instrument's downhole operating status and data are no longer possible. Therefore, instruments need a certain degree of autonomous control and self-correction capabilities to improve the quality of acquired data.

[0005] Secondly, conventional micro-resistivity imaging logging instruments typically employ a single bus configuration for their data acquisition and processing systems, such as RS-485, RS-422, or CAN. If the communication board circuit design uses only RS422 communication, the bus interface only has the function of sending data and receiving commands, without considering compatibility with other transmission systems. Similarly, if a single CAN bus communication method is used, the bus interface only has the function of sending data and receiving commands, without considering automatic data conversion and interoperability with RS-485, SPI, UART, and Ethernet protocols, resulting in significant limitations in usability.

[0006] Meanwhile, to meet the demands of higher measurement speeds and thin-layer information identification, higher requirements have been placed on measurement accuracy and acquisition rate. Therefore, the amount of data acquired and real-time performance have become bottlenecks restricting instrument performance. At the same time, the need for multi-bus data transmission that adapts to different transmission bandwidth requirements while ensuring data reliability is increasing. Summary of the Invention
