Zusammenfassung:The vertical well inclinometer while drilling with the azimuth tool face measuring function comprises a drill collar body, a power supply short section, an azimuth circuit short section, a main control circuit assembly, an electrolyte inclinometry assembly, a hydraulic control assembly and a valve set are sequentially arranged in the drill collar body, and the drill collar body is assembled into an integral device and is connected to the upper portion of a screw rod when used. After the power supply pup joint is connected with the orientation circuit pup joint, the whole machine is powered on to operate, the main control circuit assembly obtains measured orientation, tool face and other data from the orientation circuit pup joint and obtains well deviation data from the electrolyte inclinometry assembly, and opening gap adjustment of the valve set is achieved by controlling the hydraulic control assembly. According to the vertical well inclinometer while drilling, the orientation and the tool face can be accu
