safety and reliability of power system 1. safety guarantee measures for dual fuel engine technology ① The dual fuel engine has better low-speed torque performance, small speed fluctuation and fast response. It can meet the requirements of frequent changes in well site load, so as to improve the power output performance of the engine and the acceleration performance of supporting drilling machinery. ② Equipped with electronic protection function to enhance the engine control and protection function. It has overspeed protection, low oil pressure shutdown, high cylinder and exhaust temperature alarm and automatic switching to diesel mode; Imported controller is adopted, which is reliable and accurate, making the system in the optimal state in real time. ③ Equipped with solenoid valve to prevent gas supply failure. In case of insufficient gas volume, the natural gas supply will be automatically cut off and switched to pure diesel working state. 2. safety guarantee measures for natural gas power generation technology ① The operation characteristics of the natural gas generator set itself are more suitable for the requirements of drilling impact load and ensure the safety of power supply for drilling. ② one diesel generator set on site shall be kept in parallel with the natural gas generator set as the standby of the natural gas generator set. When the air source cannot be guaranteed or the natural gas unit has problems, start the diesel generator set to Ensure the reliability and safety of power supply ③ equipped with powerful control system. Each generator set is equipped with 1 local control cabinet and 1 unit circuit breaker cabinet, and each 2 generator sets is also equipped with 1 remote control cabinet, a total of 3 remote control cabinets to ensure safe and stable operation. ④ Equipped with ESM unit control system. Air fuel ratio can be achieved Automatic control, automatic grid connection, automatic adjustment of power factor, automatic load distribution, automatic loading, automatic unloading and other functions. The unit can be connected to the grid and run in parallel. The electrical system realizes the separation of strong and weak current, which is safe and convenient to operate, and is more convenient to build a large-scale automatic power station ⑤ reactive power compensation and harmonic treatment. The electric drilling system is equipped with reactive power compensation and harmonic control system, and the overall system configuration is placed in a container to solve the problems of reactive power compensation and harmonic interference. The reactive power output of the generator set shall fully meet the reactive power output requirements of the alternative diesel generator set. ⑥ Monitoring function: convenient for remote data monitoring function, which can greatly improve the automatic management level of the power station. Safety and reliability of gas system ① Special knock real-time monitoring technology is adopted. In case of knock, the fuel gas supply will be cut off automatically and the working mode of all diesel will be switched quickly. ② Gas flame arrester and special explosion-proof device are installed to avoid engine failure caused by tempering and ensure safe operation of the engine. ③ Safety valves are installed. In case of emergency, press the "emergency stop" button, the gas solenoid valve and diesel solenoid valve will be closed immediately, and the diesel actuator will immediately pull the diesel pump rack to reset, so as to shut down the unit in the shortest time and protect the safety of the unit and on-site personnel to the greatest extent
