Summary: | The invention belongs to the technical field of drilling exploration engineering, and particularly relates to a measurement while drilling nipple for coiled tubing engineering and a using method thereof. The measurement while drilling nipple is compact in structure and good in sealing performance, can be installed and connected to the near end of a coiled tubing downhole string drill bit, and achieves real-time measurement of drilling engineering parameters such as drilling pressure, torque, internal and external pressure of a drill string and casing coupling in the drilling process. The measurement while drilling nipple for coiled tubing engineering comprises a measurement nipple main body structure, a circuit board bin, a single-core pressure bearing plug, a casing coupling sensor, a flow pressure sensor, an annulus sensor, a drilling pressure sensor and a torque sensor, wherein a measurement circuit is installed in the circuit board bin, the casing coupling sensor is arranged at the front half section of t |
