The invention discloses a cable separate injection and separate production system and method capable of achieving a repeated butt joint function, and relates to the technical field of oil separate layer production. The cable separate injection and separate production system is characterized by comprising an underground tool section and an oil production equipment section which are connected through a wet joint; the wet joint comprises a male joint body and a female joint body which can be separated from each other, the male joint body is connected with the oil extraction equipment section, the female joint body is connected with the underground tool section, and the male joint body and the female joint body are used for enabling the underground tool section and the oil extraction equipment section to be repeatedly separated and in butt joint. According to the pipe column, in the pump inspection process, the tool section part does not need to be moved, only the wet joint male head and the pipe column above the
