Specifically, the output guidance parameters include: output guide force values and output tool faces (i.e., the direction of the output guide force); the target oriented parameters include: a target guiding force value and a target tool face (i.e., a direction of the target guiding force).
Preferably, the rotary steerable tool is as shown in fig. 3. Fig. 3 shows a schematic view of a rotary steerable tool. The top end of the rotary guiding tool is provided with a drill bit 301, the rear side of the drill bit 301 is provided with a bearing 302, and the rear side of the bearing 302 is provided with a slow rotating outer sleeve 303 of the rotary guiding tool; the slow rotating outer sleeve 303 can rotate slowly, and three telescopic wing ribs with included angles of 120 degrees are uniformly distributed on the cylindrical surface of the slow rotating outer sleeve 303; the rotary steering tool supports the well wall through three ribs, and then adjusts and controls the advancing direction of the drill bit 301.

Specifically, during the downhole operation, the rotary guiding tool is in a rotating state along with the drilling tool, and the rotary guiding tool is continuously and dynamically adjusted all the time in order to enable the drilling tool to drill according to the target guiding parameters in the ground command. In the actual operation process in the underground, factors such as underground environment, field construction parameters and the like all affect the consistency and stability of output guide parameters and target guide parameters of the rotary guide tool, so that the output guide parameters output by the rotary guide tool in real time cannot be kept consistent with the target guide parameters at any time, but the output guide parameters fluctuate around the target guide parameters of the ground instruction. The dynamic variation range, the frequency distribution and the dispersion of the fluctuation can present different forms under different stratum conditions, underground environments and construction parameters, so that the distribution form of the actual output guide parameters and the relation between the distribution form and the target guide parameters can be used for describing the guide efficiency of the rotary guide tool by analyzing the distribution form of the actual output guide parameters and the relation between the distribution form and the target guide parameters. In this way, different visual charts are generated according to corresponding parameters in the output guide parameters and the target guide parameters. The guiding efficiency refers to the degree of consistency between output guiding parameters output by the rotary guiding tool in real time during the downhole operation and preset guiding parameters (namely target guiding parameters) in the ground instruction.

comparing the confidence interval of the comprehensive guide efficiency with a preset confidence interval to obtain a comparison result;
and evaluating the overall efficiency of the output guide parameters of the rotary guide tool according to the comparison result and a plurality of data items in the comprehensive guide efficiency quantification chart.
Preferably, the analysis is performed on the visual chart shown in fig. 4 and the integrated guide efficiency quantification chart shown in table 1.
