Abstract: Cable bridge plug setting tool using sustained-release powder as a power source has a high cost for management and application with hidden faults in safety. Onsite service requires safer, more environmental-friendly and more economical setting tool. Electric hydraulic cable bridge plug uses a DC motor to drive micro hydraulic pump. High-pressure oil flow from hydraulic pump makes the piston work so that electric energy is converted into mechanical energy to set and release the plug. It has a number of functions, such as providing high pulling force for high setting in a limited space, restoring working status in time and resisting high temperature and high pressure. The tool can resist temperature of 155°C and working pressure of 70MPa. The output pull is no less than 300kN. As compared to the products and technology of the same kind both at home and broad, it reaches the advanced level and is able to replace the chemical energy setting tool.

Key words: closed formation, bridge plug, reset device of oil return, setting tool, hydraulic pump, micro motor
