[0044] Figure 1 FIG. 1 is a flow chart showing a method for evaluating the steering efficiency of a rotary steering tool according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0045] Step S101 : obtaining real-time output steering parameters of a rotary steering tool and target steering parameters of the rotary steering tool during downhole operation.

[0046] Specifically, the target steering parameter is a preset steering parameter in the ground instruction of the rotary steering tool.

[0047] Step S102: Generate a guidance parameter visualization chart based on the output guidance parameter and the target guidance parameter.

[0048] Specifically, the guidance parameter visualization chart includes: a guidance force efficiency chart and a tool face efficiency chart.

[0049] Step S103 , performing vector calculation on the output steering parameter and the target steering parameter, determining the comprehensive steering efficiency of the output steering parameter, and generating a comprehensive steering efficiency visualization chart and a comprehensive steering efficiency quantitative chart.

[0050] Step S104 : analyzing the visual chart of the steering parameters, the visual chart of the comprehensive steering efficiency, and the quantitative chart of the comprehensive steering efficiency to evaluate the steering efficiency of the rotary steering tool.

[0051] According to a method for evaluating the steering efficiency of a rotary steering tool provided by this embodiment, the output steering parameters of the rotary steering tool and the target steering parameters of the rotary steering tool in real time during downhole operation are obtained; a steering parameter visualization chart is generated based on the output steering parameters and the target steering parameters; vector calculation is performed on the output steering parameters and the target steering parameters to determine the comprehensive steering efficiency of the output steering parameters, and a comprehensive steering efficiency visualization chart and a comprehensive steering efficiency quantitative chart are generated; the steering parameter visualization chart, the comprehensive steering efficiency visualization chart, and the comprehensive steering efficiency quantitative chart are analyzed to evaluate the steering efficiency of the rotary steering tool. Using the technical solution provided by the present invention, it is possible to analyze the visualization chart and quantitative chart generated based on the output steering parameters and the target steering parameters of the rotary steering tool during operation, so as to accurately, quickly, and intuitively evaluate the steering efficiency of the rotary steering tool in operation, thereby helping the rotary steering tool to perform technical iteration and upgrade, and helping to promptly discover problems existing in the operation of the rotary steering tool.

[0052] Figure 2 FIG. 4 is a flow chart showing a method for evaluating the steering efficiency of a rotary steering tool according to another embodiment of the present invention. Figure 2 As shown, the method includes the following steps:

[0053] Step S201: obtaining real-time output steering parameters of a rotary steering tool during downhole operation and target steering parameters of the rotary steering tool.

[0054] The output steering parameters are actual parameters output in real time by the rotary steering tool during operation; and the target steering parameters are target parameters in ground instructions received by the rotary steering tool during operation.

[0055] Specifically, the output steering parameters include: output steering force value and output tool surface (i.e., direction of output steering force); the target steering parameters include: target steering force value and target tool surface (i.e., direction of target steering force).

[0056] Preferably, the rotary guide tool is as follows Figure 3 shown. Figure 3 A schematic diagram of the structure of a rotary steerable tool is shown. The tool has a drill bit 301 at its top, a bearing 302 behind the drill bit 301, and a slow-rotating outer sleeve 303 behind the bearing 302. The slow-rotating outer sleeve 303 rotates slowly, and its cylindrical surface is evenly distributed with three retractable ribs at an angle of 120 degrees. The three ribs support the wellbore wall, thereby adjusting and controlling the forward direction of the drill bit 301.

[0057] Step S202 , statistically describing the output guiding force value and the target guiding force value to generate a guiding force efficiency chart.

[0058] Specifically, during downhole operations, the rotary steerable tool rotates with the drill string. To ensure the drill string drills according to the target steering parameters in the surface command, the tool continuously and dynamically adjusts. However, during actual downhole operations, factors such as the downhole environment and on-site operation parameters affect the consistency and stability of the tool's output steering parameters and the target steering parameters. Therefore, the output steering parameters output by the tool in real time cannot always remain consistent with the target steering parameters. Instead, the output steering parameters fluctuate around the target steering parameters in the surface command. The dynamic range, frequency distribution, and discreteness of these fluctuations vary depending on the formation conditions, downhole environment, and operation parameters. Therefore, analyzing the actual distribution of the output steering parameters and their relationship with the target steering parameters can be used to describe the steering efficiency of the rotary steerable tool. In this way, different visualization charts are generated based on the corresponding parameters between the output steering parameters and the target steering parameters. Steering efficiency refers to the degree of consistency between the output steering parameters output by the rotary steerable tool in real time during downhole operations and the preset steering parameters (i.e., the target steering parameters) in the surface command.

[0059] Preferably, a guiding force efficiency graph may be drawn based on the percentages of the output guiding force value and the target guiding force value relative to the maximum guiding force of the rotary guiding tool.

[0060] Step S203 , statistically describing the output tool face and the target tool face to generate a tool face efficiency chart.

[0061] Preferably, a tool face efficiency graph is drawn based on the angle between the output tool face and the guide direction of the target tool face.

[0062] Step S204: performing vector calculation on the output guidance parameter and the target guidance parameter.

[0063] Specifically, a first vector is generated using the output guide force value and the output tool surface, and a second vector is generated using the target guide force value and the target tool surface;

[0064] Step S205 , calculating the projection value of the first vector in the direction of the second vector, determining the comprehensive guidance efficiency of the output guidance parameter based on the projection value, and generating a visualization chart of the comprehensive guidance efficiency.

[0065] Preferably, the inner product of the first vector formed by the real-time output guidance parameters and the second vector formed by the target guidance parameters in the ground instructions is solved to obtain the projection value of the first vector in the direction of the second vector, and normalized to obtain the comprehensive guidance efficiency of the output guidance parameters for the target guidance parameters.

[0066] Preferably, the guidance parameter visualization chart and the comprehensive guidance efficiency visualization chart are as follows: Figure 4 shown. Figure 4 A schematic diagram of a visualization chart according to an embodiment of the present invention is shown.

[0067] The tool face efficiency curve shows the relationship between the output and target guiding forces at depth, based on the angle between the output and target tool faces. The guiding force efficiency curve shows the relationship between the output and target tool faces at depth, based on the output guiding force value and the percentage of the target guiding force to the maximum guiding force. A comprehensive guiding efficiency of 1 indicates that the output and target guiding parameters are consistent, resulting in the highest guiding efficiency.

[0068] Among them, in the tool face efficiency histogram, guiding force efficiency histogram and comprehensive guiding efficiency histogram, the target tool face, output tool face, target guiding force, output guiding force and comprehensive guiding efficiency are all acquired data; while the output tool face_DBSCAN, output guiding force_DBSCAN and comprehensive guiding efficiency_DBSCAN are data calculated by the clustering algorithm.

[0069] Step S206 , calculating multiple data items of the comprehensive guidance efficiency, and generating a comprehensive guidance efficiency quantitative chart based on the multiple data items.

[0070] Specifically, the multiple data items include: mean, median and standard deviation.

[0071] Preferably, the comprehensive guiding efficiency quantification chart is shown in Table 1. Table 1 shows a comprehensive guiding efficiency quantification chart according to an embodiment of the present invention.

[0072]

[0073] Table 1

[0074] Step S207 : analyzing the visual chart of the steering parameters, the visual chart of the comprehensive steering efficiency, and the quantitative chart of the comprehensive steering efficiency to evaluate the steering efficiency of the rotary steering tool.

[0075] Specifically, analyzing the visual graph of the guidance parameters to evaluate the consistency between the output guidance parameters and the target guidance parameters and the stability of the output guidance parameters;

[0076] Analyzing the comprehensive guidance efficiency visualization chart to obtain a confidence interval of the comprehensive guidance efficiency;

[0077] Comparing the confidence interval of the comprehensive guidance efficiency with a preset confidence interval to obtain a comparison result;

[0078] The overall efficiency of the output steering parameters of the rotary steering tool is evaluated based on the comparison result and multiple data items in the comprehensive steering efficiency quantification chart.

[0079] Preferably, for Figure 4 The visual chart shown and the quantitative chart of comprehensive guidance efficiency shown in Table 1 are used for analysis.

[0080] according to Figure 4 The tool face efficiency curve shown is used to evaluate the consistency between the output tool face and the target tool face, and to find the well sections with poor consistency.

[0081] according to Figure 4 The steering force efficiency curve shown is used to evaluate the consistency between the output steering force and the target steering force, and to identify the well sections with poor consistency.

[0082] according to Figure 4 As shown in the comprehensive guidance efficiency curve, the value range of the comprehensive guidance efficiency is between 0.9 and 1.1, which is normal, that is, the confidence interval is [0.9, 1.1].

[0083] according to Figure 4 The tool face efficiency histogram and the guide force efficiency histogram shown in the figure indicate the degree of convergence of the output tool face and the output guide force relative to the target tool face and the target guide force. Those skilled in the art can set a preset confidence interval for the comprehensive guide efficiency based on actual needs. For example, the preset confidence interval may be [0.9, 1.1]. In this case, the confidence interval of the comprehensive guide efficiency statistical results should satisfy the preset confidence interval [0.9, 1.1]. A confidence level greater than 95% may be required.

[0084] Analysis of the quantitative chart:

[0085] In a specific application, with reference to Table 1, the overall statistics of the steering efficiency of the rotary steering tool should meet the following requirements: 0.95 < mean < 1.05; 0.95 < median < 1.05; and standard deviation < 0.1.

[0086] According to a method for evaluating the steering efficiency of a rotary steering tool provided in this embodiment, the steering efficiency of the rotary steering tool during operation can be analyzed by using visual charts and quantitative charts generated by the output steering parameters and target steering parameters of the rotary steering tool, and the actual steering efficiency of the rotary steering tool can be quickly evaluated intuitively and quantitatively, providing an accurate basis for on-site optimization of construction parameters, improvement of steering efficiency, and improvement of instrument performance and technical upgrades.

[0088] The acquisition module 501 is used to acquire the real-time output steering parameters of the rotary steering tool and the target steering parameters of the rotary steering tool during downhole operation.

[0089] Specifically, the target steering parameter is a preset steering parameter in the ground instruction of the rotary steering tool.
