Beschreibung
Zusammenfassung:	The invention belongs to the technical field of petroleum and natural gas exploration, and discloses a coiled tubing drilling guide device which comprises an upper connecting assembly, a middle outer cylinder, a first motor assembly, a second motor assembly and a lower connecting assembly. The upper connecting assembly is connected with a measurement-while-drilling tool, and the lower connecting assembly is connected with a drilling tool. The first motor assembly and the second motor assembly are both arranged in a cavity of the middle outer cylinder, the second motor assembly is connected with the output end of the first motor assembly, the axis of a cavity of a second outer cylinder of the second motor assembly does not coincide with the axis of a body of the second outer cylinder, an eccentric sleeve is arranged in the cavity of the second outer cylinder, and an eccentric hole is formed in the eccentric sleeve. The axis of the eccentric hole does not coincide with the axis of the body of the axis of the ec
