Abstract: In response to the functional limitations of current mechanical plugging tools, such as limited downhole operation times and small port flow area, a radio frequency identification (RFID) circulation bypass tool with independent intellectual property rights was successfully developed through systematic technical research and development. It consists of an RFID communication system, a power supply system, a hydraulic control system, a mechanical execution system, etc. It can be switched on and off more than 30 times, and the bypass flow area is more than 5 times larger than that of conventional tools, achieving full internal diameter. The tool has been tested in four wells, including the Well bDT23012 in Baikouquan Oilfield and the Well HW1250 in Xinjiang Oilfield. The test results show that the tool has good stability and reliability, which can improve the technical level of plugging while drilling and large-displacement well washing operations, meet the needs of plugging while drilling operations under special geological conditions, special working conditions, and special drilling tool structures, and form a series of products with mechanical plugging tools.
