Abstract：In the process of oilfield production，poor tubing and casing connectivity often leads to reduced production.Traditionally，the perforation technology using gunpowder has been employed to restore connectivity.However，this method is prone to causing damage to the casing.In view of this， based on the modular design concept，a downhole electric tubing puncher was innovatively developed. This tool utilized an electro-hydraulic thrust system and was capable of achieving precise punching operations on the tubing.Through this approach，while effectively enhancing the tubing and casing connectivity，it successfully preserved the structural integrity of the casing，avoiding a series of subsequent problems caused by casing damage. Verified by experiments，this downhole electric tubing puncher exhibited excellent performance and effects，providing solid technical support for subsequent production increase operations in the oilfield and possessing remarkable technological innovation and broad application prospects.
