Zusammenfassung:The invention relates to the technical field of underground equipment, in particular to a coiled tubing drilling orientation mechanism. The mechanism comprises a pipe body, electrode assemblies, electrorheological fluid, and a drilling and production mechanism; an inner pipe is arranged in the axial direction of the pipe body in a sleeving mode, and a plurality of sealed spaces are formed betweenthe pipe body and the outer wall of the inner pipe; the electrode assemblies are arranged in the sealed spaces respectively; the electrorheological fluid is arranged in the sealed space and connectedwith the electrode assemblies; the electrorheological fluid has a fluid state and a solid state driven by the electrode assemblies; and the drilling and production mechanism is arranged at one end ofthe pipe body and is suitable for converting the rotating angle of the pipe body. The coiled tubing drilling orientation mechanism and drilling and production equipment are not prone to deviating in direction. The invention fur
