Continuous gyroscopic survey system for directional well

The invention discloses a continuous gyroscopic survey system for a directional well. The system comprises a computer, a control cabinet and an inclinometer, wherein a serial port of the computer is connected with a communication port of the control cabinet; a cable interface of the control cabinet is connected with the end part of the inclinometer through a cable; the inclinometer comprises a cable head, an upper centralizer, an instrument short section, a lower centralizer, a weight bar, a vibration damper and a guiding shoe which are connected with one another sequentially; and a connecting end of the cable head is connected with the cable. The system can continuously measure a well track in an all-dimensional mode, has high measurement accuracy and high efficiency, and can be used in directional drilling and the measurement of the well track.
