Semi-physical test system for curvature control method of rotary steering tool

The invention discloses a semi-physical test system for a curvature control method of a rotary steering tool. The semi-physical test system comprises an upper computer, a real-time simulation machine and a real master control calculation unit, a virtual inclinometer probe module and a tool guiding characteristic module are implanted in the real-time simulation machine, and a curvature control method module is implanted in the real master control calculation unit. According to the invention, the curvature control method module obtains the tool guiding parameter according to the well deviation azimuth curvature difference value, the tool guiding characteristic module obtains the current well deviation azimuth parameter according to the tool guiding parameter, and the virtual inclinometry probe module obtains the current virtual sensor signal according to the current well deviation azimuth parameter. The problems of high cost and low efficiency of all-physical testing and the problem of low confidence of all-dig
