Coiled Tubing Applications and Measurement Tool

A system that generates pressure pulses in a drilling fluid within a well bore that exists within a coiled tubing assembly, said system comprising:

• a tool within which exists a valve portion longitudinally and axially positioned within a center portion of a main valve assembly, said assembly including a main valve, a main valve pressure chamber, and a main valve orifice with said main valve, such that as said drilling fluid flows downward along said well bore said drilling fluid splits into both an inlet main fluid stream and a pilot fluid stream, wherein said pilot fluid stream flows through a pilot flow annulus and into a pilot flow inlet channel, wherein said pilot fluid stream then flows into a main valve fluid feed channel until it reaches said main valve pressure chamber and through a pilot valve section that functions as a pulser generating portion of said tool that further comprises a pilot valve housing, a pilot shaft positioned in a central axial position within said tool supported by thrust bearings, a seal carrier, upper and lower rotary seals, and a pilot inlet cam and a pilot outlet cam such that said pilot shaft can rotate said pilot inlet cam and pilot outlet cam inside a pilot sleeve with matching orifices so that said pilot fluid stream is controlled by movement of said pilot inlet cam and said pilot outlet cam and wherein said pilot fluid stream fluid flows into and through a pilot flow outlet channel such that said pilot fluid stream fluid recombines with a main fluid flow to become a main exit fluid flow.
