[0054] Specifically, the rotary steering tool can be a push-type rotary steering tool, Figure 3 A structural schematic diagram of a rotary steering tool is shown, as shown in Figure 3As shown, the top end of the rotary steering tool is a drill bit 301, the rear side of the drill bit 301 is a bearing 302, and the rear side of the bearing 302 is the slow rotating sleeve 303; the slow rotating sleeve 303 is distributed with three retractable wing ribs 304, the three wing ribs 304 are uniformly distributed at an angle of 120 degrees on the cylindrical surface of the slow rotating sleeve 303, and are used to support the well wall and generate a specific direction of guiding force. When the rotary steering tool is steered drilling, the slow rotating sleeve 303 can slowly rotate, the three wing ribs 304 support the well wall and slowly rotate with the slow rotating sleeve 303, and at this time the size and direction (steering tool face) of the guiding force are the size and direction of the resultant force of the three wing ribs 304. In order to keep the size and direction of the guiding force unchanged during drilling, the pushing force of the three wing ribs 304 is in a dynamic adjustment state during slow rotation. The pushing force of each wing rib 304 is provided by the hydraulic mechanism corresponding to each wing rib in the rotary steering tool, and the hydraulic mechanism is composed of a piston cylinder and a motor pump and the like, and the pushing force is adjusted by controlling the control parameters of the piston cylinder and the motor pump.

[0055] In step S202, a plurality of visualized charts are constructed according to the control parameters of the piston cylinder, the motor pump, the slow rotating sleeve and the wing rib.

[0056] Specifically, the visualized charts are constructed according to the system output result parameters and the system control process parameters in the control parameters.

[0057] According to the system output result parameters, the visualized charts include a three-piston cylinder pressure curve chart, a slow rotating sleeve rotation angle curve chart, a target guiding force curve chart, a three-piston cylinder pressure distribution histogram, a three-wing rib pushing force distribution histogram and a slow rotating sleeve rotation angle distribution chart, as shown in Figure 4 . Figure 4 The visualized charts based on the system output result parameters according to another embodiment of the present application are shown, in which the three piston cylinders are referred to as 1# cylinder, 2# cylinder and 3# cylinder, and the three wing ribs are referred to as 1# wing rib, 2# wing rib and 3# wing rib.

[0058] According to the system control process parameters, the visualized charts include a motor speed and pump cylinder pressure relationship chart of the three motor pumps, a motor current and pump cylinder pressure relationship chart of the three motor pumps, a motor speed and motor current relationship chart of the three motor pumps, a pump cylinder pressure distribution histogram of the three motor pumps, a motor speed distribution histogram of the three motor pumps and a motor current distribution histogram of the three motor pumps, as shown in Figure 5 . Figure 5 The visualized charts based on the system control process parameters according to another embodiment of the present application are shown, in which the three motor pumps are referred to as 1# motor, 2# motor and 3# motor.

[0059] Step S203, according to the control parameters of the piston cylinder, wing rib and motor pump, a plurality of quantification charts are constructed.

[0060] Specifically, the quantification charts are constructed according to the control parameters based on the system output result parameters and the system control process parameters.

[0061] According to the pressures of the three piston cylinders (referred to as 1# cylinder, 2# cylinder and 3# cylinder respectively), the pressure average, the pressure median, the pressure maximum value and the pressure minimum value of the three piston cylinders are calculated to obtain the pressure quantification chart of the three piston cylinders; according to the pushing forces of the three wing ribs (referred to as 1# wing rib, 2# wing rib and 3# wing rib respectively), the pushing force average, the pushing force median, the pushing force maximum value and the pushing force minimum value of the three wing ribs are calculated to obtain the pushing force quantification chart of the plurality of wing ribs, as shown in Table 1:

[0062] Statistical description 1# cylinder pressure 2# cylinder pressure 3# cylinder pressure 1# wing rib push force 2# wing rib push force 3# wing rib push force Mean value 12.969 13.633 12.505 13.83 14.278 13.247 Median value 13.252 14.294 12.176 14.176 14.991 12.838 Maximum value 22.659 23.346 22.829 25.479 25.963 25.733 Minimum value 3.052 3.38 2.986 2.002 2.036 1.995

[0063] Table 1

[0064] According to the operating parameters of the three motor pumps (referred to as 1# motor pump, 2# motor pump and 3# motor pump respectively), the pump cylinder pressure average, the pump cylinder pressure maximum value, the pump efficiency, the motor efficiency and the motor pump load of the three motor pumps are calculated to obtain the operating parameter quantification chart of the three motor pumps, as shown in Table 2:

[0065] Performance parameters: Pump efficiency (MPa / rev) Motor efficiency (MPa / Amp) Motor pump load (Amp / rev) 1# motor pump 0.00883 43.5431 0.0001773 2# motor pump 0.00826 63.0815 9.7e-05 3# motor pump 0.00927 81.1696 9.7e-05

[0066] Table 2

[0067] Step S204, the visualization charts and the quantification charts are analyzed to evaluate the quality of the current operation of the rotary steering tool.

[0068] Specifically, the plurality of visualization charts and the quantification charts are analyzed to obtain the relationship between the control parameters, the parameter range of each control parameter and the uniformity of the change of each control parameter; according to the relationship between the control parameters, the parameter range of each control parameter and the uniformity of the change of each control parameter, the performance of the piston cylinder, the slow rotation outer sleeve, the wing rib and the motor pump of the rotary steering tool is evaluated.

[0069] Preferably, the visualization charts shown in Figure 4 , Figure 5 and the quantification charts shown in Table 1 and Table 2 are analyzed.

[0070] In Figure 4In the three-piston cylinder pressure curve of the three-piston cylinder pressure curve, the three cylinder pressure curves show a standard sinusoidal shape, and the fluctuation amplitudes of the three curves are basically the same. If the fluctuation amplitude of a curve is obviously low, it indicates that there is a cylinder pressure deficiency. The amplitude of the three-piston cylinder pressure curve alternately leads, and when one curve reaches the maximum, the other two curves intersect at the low value. When it reaches the minimum, the other two curves intersect at the high value. If the curve of the three-piston cylinder tends to zero, it indicates that the rotary steering tool has a restart phenomenon. The slow rotating sleeve angle curve changes periodically and stably (without or with few jumps), and the speed of the slow rotating sleeve rotation determines the frequency of the pressure change of the three-piston cylinder. The sinusoidal period of the three-piston cylinder pressure is consistent with the change period of the slow rotating sleeve angle. In the three-piston cylinder pressure distribution histogram, the pressure distribution ranges of the three pistons should be consistent, and the distribution shape should be consistent. The slow rotating sleeve angle should be uniformly distributed from 0 degrees to 360 degrees. If the distribution of a certain angle is obviously high, it may indicate that the three-wing rib pushing force is not normal. If the three-piston cylinder pressure data at the horizontal coordinate 0 point is obviously high, and the slow rotating sleeve data at 180 degrees is obviously high, the rotary steering tool may have a restart phenomenon.

[0071] In Figure 5 , the motor speed and pump cylinder pressure relationship diagram of the three motor pumps is a scatter plot, which is used to evaluate the pump efficiency. The larger the slope of the scatter plot fitting regression line, the higher the pump efficiency. The motor current and pump cylinder pressure relationship diagram of the three motor pumps is a scatter plot, which is used to evaluate the motor work efficiency (i.e. motor efficiency). The larger the slope of the scatter plot fitting regression line, the higher the motor efficiency. The motor speed and motor current relationship diagram of the three motor pumps is a scatter plot, which is used to evaluate the load of the motor pump. The larger the slope of the scatter plot fitting regression line, the larger the load of the motor pump. At the same time, by analyzing the consistency of the pump efficiency, motor efficiency and motor pump load of the three motor pumps through the above multiple scatter plots, the system short board can be found. For the pump cylinder pressure, motor speed and motor current distribution histogram of the three motor pumps, by analyzing the consistency and parameter distribution of the three motor pumps, the performance of the three motor pumps can be evaluated.

[0072] For the analysis of the quantification chart:

[0073] For Table 1, the mean and median of the pressure of the three pistons and the pushing force of the three wings should be consistent, and preferably the value range is 12-14. Analyze whether the mean and median values of the piston pressure and the pushing force of the wing are uniform, low or high: if the mean value of the two types is low, it indicates that the cylinder pressure is low; if the mean and median are inconsistent, it indicates that the slow rotating sleeve rotates unevenly. Preferably, the highest value of the pressure of the three pistons should be in the range of 22-24, and the values should be basically consistent.

[0074] For Table 2, the relationship between each parameter shown in Table 2 is analyzed, combined with Figure 5 the slope of each regression curve in the middle to evaluate the consistency of the three motor pumps, further find the short board, and evaluate the performance of the pump efficiency, motor efficiency, etc. of the three motor pumps. Among them, the pump efficiency represents the pressure value (i.e. output cylinder pressure) established at the pump output end by the unit speed at the pump input end. The greater the output cylinder pressure, the higher the pump efficiency. The motor efficiency is the pressure value established at the pump output end by the unit current at the motor input end (at the same time, since the current size is proportional to the power when the voltage is constant, the unit power can be obtained according to the unit current). The greater the output cylinder pressure, the higher the motor efficiency. The motor pump load is the current (i.e. input power) that needs to be input by the motor output unit speed. The greater the current that needs to be input, the greater the load of the motor pump.

[0075] Preferably, the overall performance of the three motor pumps obtained by analysis is as shown in Figure 6 . Figure 6 A three-motor pump performance comparison diagram according to another embodiment of the present application is shown, in which the three motor pumps are referred to as 1# motor pump, 2# motor pump and 3# motor pump.

[0076] Among them, the outermost circle is the highest value position of each performance (i.e. the proportion is 100%), and the internal scale value is the percentage of the proportion. According to the values of each performance of each motor pump, the performance diagram of each motor pump is obtained, and then the relationship between the performances of the three motor pumps is obtained.

[0077] According to the rotating guide tool operation quality control analysis method provided by the embodiment, the control parameters of the rotating guide tool in the work can be analyzed by using the visual chart and the quantitative chart, the operation quality of the rotating guide tool can be quickly evaluated, the hidden danger or system short board in the field operation can be found in time, and accurate basis can be provided for instrument maintenance and maintenance, instrument performance improvement and technology upgrading.
