The invention discloses a flexible connector for dual-layer continuous oil pipes, which is mainly used for a connection between a tube body and a tool when a connecting tool for the dual-layer continuous oil pipes for an oil and gas field works, and compensative regulation of expansion amounts of inner and outer layers of the continuous oil pipes. A connector for the outer layer of continuous oil pipe is connected to the outer wall of the outer layer of the continuous oil pipe in a tight occlusion manner through slips, the inner layer of the continuous oil pipe slides on an inner pipe regulating sleeve of a telescopic cylinder to complete flexible compensation, an outer cylinder regulating sleeve and the inner pipe regulating sleeve of the telescopic cylinder are connected to an outer pipe slip connector, so that an inner pipe body and an outer pipe body are fixedly connected in a sealed manner; screw threads at the bottom ends of the outer cylinder regulating sleeve and the inner pipe regulating sleeve are respectively connected to related tools, so that the operational requirements of the dual-layer continuous oil pipes with the tools are met, and construction operations, such as negative pressure sand removal, drilling, grinding and testing, can be carried out. The flexible connector has the advantages of compact structure, reliable work and simplicity in operation.
