The invention belongs to the field of logging equipment, and particularly discloses a universal detection device of a logging instrument. The universal detection device comprises a power module and a detection interface module which is connected with a master control module, wherein the detection interface module is connected with the logging instrument through a cable; the detection interface module comprises an RS232 interface, an RS485 interface, a Manchester encoding interface, a CAN (Controller Area Network) interface and an ADSL (Asymmetrical Digital Subscriber Line) interface; and the master control module is communicated with a computer. According to the universal detection device, different instruments can be quickly detected, the complexity for connecting the entire testing system is saved to realize better service to the field, and an RJ45 network interface wireless transmission technology is adopted to communicate with the computer, so that the device is convenient and easy to operate.
Description
technical field [0001] The invention belongs to the field of logging equipment, in particular to a general detection device for logging tools. Background technique [0002] In order to meet the requirements of exploration and development objectives, the reliability of logging tools must be improved. The downhole logging tool converts non-electrical signals into electrical signals through sensors to facilitate the measurement of the instrument. The data measured by the downhole logging tool is transmitted to the ground through various algorithms, coding, encryption and other data processing. The ground system converts the measurement data into various parameters for interpretation by ground technicians through decoding, decryption and other means. [0003] At present, the communication methods in the field of petroleum logging are complicated, and generally, relatively stable and reliable communication methods are used. Different logging systems require different communicati...
