Oil pipe inner blanking plug started through compressed gas

The utility model belongs to the technical field of oil and gas field development engineering, and discloses an oil pipe inner blanking plug started by compressed gas, which comprises a guide head, a sealing rubber sleeve, a driving module and an upper joint which are connected in sequence, a compressed gas cylinder, a plug valve connected with an opening of the compressed gas cylinder, a motor for driving the plug valve, a check valve and a battery pack are arranged in the driving module; one end of the check valve is communicated with the plug valve, and the other end is communicated with the inside of the sealing rubber sleeve. According to the oil pipe inner blanking plug started through the compressed gas, the sealing rubber sleeve and the slip are expanded through the pressure difference of the compressed nitrogen, one-time setting is achieved, the risk of manual operation errors is reduced, and the setting success rate is increased. And meanwhile, the setting force can be adjusted by adjusting the pres
