Borehole track control method and borehole track control system

The invention relates to a borehole track control method and a borehole track control system. The borehole track control system method comprises the following steps: step 1 preparing for guide tool drilling down: namely performing drill tool preparing work according to design of a guide drill tool combination and a drill column structure, measuring into-well drill tools on site, giving numbers to the drill tools and recording the parameters of the drill tools according to into-well sequence; step 2 arranging guide initial work parameters, testing a guide well drilling system to inspect if the system works normally, enabling the drilling tool combination to drill downwards after the guide system is tested to be normal; step 3 after the drill tools drill down to the bottom of a well, performing rotation guide well drilling work according to the initial work parameters set in the step 2, and monitoring a borehole track while performing the work, and adjusting track design in real time according to monitored data; and step 4 finishing guide well drilling operation and tripping out a guide tool. The borehole track control method and the borehole track control system have the advantages of reducing downward transmitting information amount, improving system reliability, well meeting the requirements for underground intelligent guide control and improving work efficiency of a rotation guide well drilling system.
