Description

Technical Field

[0001] The present application relates to the field of energy drilling technology, and in particular to a method, device, medium and program product for generating design parameters of drill bit cutting teeth. Background Art

[0002] Polycrystalline diamond compact (PDC) is the core component of PDC drill bits, typically featuring a flat, circular structure. Its performance determines the penetration rate and ROP of the PDC drill bit cutters. Due to their high rock-breaking efficiency and significant potential for increased drilling speed, PDC drill bit cutters are widely used in oil and gas drilling. With the increasing number of deep, complex strata encountered in drilling operations, there is an urgent need to develop suitable PDC drill bit cutters and improve their performance through evaluation and optimization to meet the performance requirements of practical applications.

[0003] In the prior art, the design parameters of drill bit cutting teeth are determined by optimizing the PDC tooth profile using the rock-breaking efficiency coefficient as an indicator. Specifically, the rock-breaking efficiency coefficient of the PDC drill tooth is first obtained based on the rock-breaking specific work calculation formula and the force efficiency mathematical model of the PDC drill tooth, which is used to evaluate the rock-breaking performance of the PDC drill tooth. Then, a finite element model of the PDC drill tooth rock-breaking is established, including importing the geometric model of the PDC drill tooth into the rock finite element model, meshing, numerical rock sample mechanical parameter calibration, and assigning material parameters to the PDC drill tooth and rock, in order to conduct numerical simulation experiments on the rock-breaking performance of the PDC drill tooth and obtain the rock-breaking efficiency index of the PDC drill tooth under different parameters. Finally, the obtained rock-breaking efficiency coefficients are compared to obtain a tooth selection priority table, and the optimal PDC tooth profile suitable for the specific formation is selected based on the table, thereby obtaining the design parameters of the PDC drill bit cutting teeth.

[0004] However, when using the above method to generate the design parameters of drill bit cutters, relying solely on the single indicator of rock breaking performance has certain limitations, which can easily lead to the designed drill bit cutters performing poorly or failing prematurely in challenging special formation drilling operations.

[0064] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0065] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0066] The terms "first," "second," "third," "fourth," and so forth (if any) in the description and claims of the present invention and in the accompanying drawings are used to distinguish between similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be practiced in sequences other than those illustrated or described herein.

[0067] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0068] At present, when determining the design parameters of drill bit cutting teeth by adopting the PDC tooth profile optimization method with rock breaking efficiency coefficient as an indicator, the rock breaking performance of various drill bit cutting teeth is evaluated based on the rock breaking efficiency coefficient, so as to select the tooth profile of the drill bit cutting teeth suitable for the specific formation, that is, the design parameters of the drill bit cutting teeth.

[0069] However, relying solely on rock-breaking performance as a single indicator has certain limitations, which can easily lead to the designed drill bit cutting teeth performing poorly or failing prematurely in challenging special formation drilling operations.

[0070] The root cause of the above problems lies in the fact that different geological formations have different performance requirements for drill bit cutters. Determining the design parameters of drill bit cutters based solely on rock-breaking performance makes it difficult to ensure that they can operate efficiently and sustainably under challenging drilling conditions in special formations. For example, even if the rock-breaking performance requirements are met, when a PDC drill bit is drilling in heterogeneous formations, the different lithology of the rocks will cause a significant impact on the PDC drill bit cutters, which will still cause the cutters to fail prematurely. In highly abrasive formations, the highly abrasive rocks will severely wear out the PDC drill bit cutters, which will also cause them to fail prematurely. This shows that there are limitations in generating drill bit cutter design parameters based solely on the rock-breaking performance of the drill bit cutters.

[0071] In light of this, this application proposes a method for generating design parameters for drill bit cutters. First, parameter information (including structural and material parameters) for different types of drill bit cutters, as well as data on various performance indicators for each type of drill bit cutter, is obtained. Through analysis, a mapping relationship between these parameters and the various performance indicators of the drill bit cutters is obtained. Then, based on the type of target drill bit cutter to be designed, its expected performance indicators, and the performance type of the target drill bit cutter (i.e., performance requirements), the design parameters of the target drill bit cutter are derived, combining the mapping relationship between the parameters of different types of drill bit cutters and their performance indicators. This method comprehensively considers multiple performance indicators, generating more practical and targeted parameters, thereby ensuring that the designed drill bit cutter meets the performance requirements of different geological conditions.

[0072] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0073] Figure 1 This is a flow chart of a method for generating design parameters of drill bit cutting teeth provided in an embodiment of the present application, taking the design platform of the drill bit cutting teeth as an example. Figure 1As shown, the method for generating design parameters of drill cutting teeth provided in this embodiment includes the following steps:

[0074] S101: Obtain mapping relationships between parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth.

[0075] In the embodiments of the present application, the parameters of the drill bit cutting teeth may include structural and material parameters. The performance indicators of the drill bit cutting teeth may include rock breaking efficiency, impact resistance, wear resistance, and speed-increasing potential. The types of drill bit cutting teeth may include special-shaped teeth such as conical teeth, axe-shaped teeth, and arched teeth, as well as flat rounded teeth. This application does not impose any specific restrictions on the types of drill bit cutting teeth.

[0076] Understandably, different types of drill bit cutters correspond to different parameters, and the structural and material parameters of drill bit cutters directly affect their performance in various aspects of the drilling process. Therefore, by obtaining the mapping relationship between the parameters of various types of drill bit cutters and their various performance indicators, we can reveal the mechanism by which drill bit cutter parameters affect various performance indicators, thus providing a basis for the subsequent design and optimization of drill bit cutters.

[0077] Optionally, obtaining a mapping relationship between parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth includes:

[0078] For each type of drill bit cutting teeth, test the various performance indicators of the drill bit cutting teeth under different parameters;

[0079] Based on the performance indicators of the drill bit cutting teeth under different parameters, a mapping relationship between the parameters of the drill bit cutting teeth and the performance indicators of the drill bit cutting teeth is established.

[0080] In an embodiment of the present application, for each type of drill cutting tooth, its corresponding various performance indicators under a set of parameters (including structural parameters and material parameters) can be tested, and experimental results of various performance indicators can be obtained, so as to establish a mathematical relationship model between the parameters of the drill cutting teeth and various performance indicators based on the experimental data corresponding to each performance indicator.

[0081] For example, when the performance indicators include rock-breaking efficiency, impact resistance, wear resistance, and speed-increasing potential, the rock-breaking efficiency and speed-increasing potential of the drill cutters can be tested through single-cut rock-breaking tests, the impact resistance of the cutters can be tested through impact tests, and the wear resistance of the cutters can be tested through wear resistance tests. Rock-breaking efficiency can be expressed using mechanical specific energy, wear resistance can be expressed using ground surface area or wear volume, speed-increasing potential can be expressed using the ability of the cutters to penetrate the formation, and impact resistance can be expressed using the final failure energy value.

[0082] Figure 2 This is a schematic diagram of a single tooth rock breaking experiment provided in the embodiment of the present application. Figure 2 The process of testing the rock-breaking efficiency and speed-increasing potential of drill bit cutters is introduced.

[0083] Mechanical specific energy (MSE) refers to the work done to excavate or crush a unit volume of rock. A smaller MSE means less work done to crush a unit volume of rock, and a higher rock-breaking efficiency. Conversely, a larger MSE means more work done to crush a unit volume of rock, and a lower rock-breaking efficiency.

[0084] like Figure 2 As shown, a single-tooth rock breaking experiment was carried out using a vertical turret lathe. The drill bit cutting tooth 1 cuts rock 2 at a fixed cutting speed 3 and cutting depth (DOC) 4.

[0085] The calculation formula of MSE is shown in formula (1):

[0086]

[0087] in, is the average cutting force, is the cutting distance, is the volume of cuttings. Average cutting force It refers to the average value of the interaction force between the drill bit cutting teeth and the rock along the direction of relative motion.

[0088] Obtained by taking the average of the force data measured by the three-axis force sensor; cutting distance Refers to the relative movement distance between the drill bit cutting teeth and the rock; the cuttings volume It refers to the volume of rock chips cut by the drill bit cutting teeth on the rock surface.

[0089] Furthermore, because the effective working area of ​​a drill bit's cutter under a given axial force determines the drill bit's ROP under that condition, the cutter's ability to penetrate the formation—that is, the ratio of the cutter's effective working area to its axial force—is used to reflect the cutter's potential for increasing speed.

[0090] For example, the ability of the drill bit cutting teeth to penetrate the formation can be calculated using the following formula (2):

[0091]

[0092] in, The ability of the drill bit cutting teeth to penetrate into the formation. is the effective working area of ​​the drill bit cutting teeth, is the rock-breaking axial force of the drill bit cutting teeth.

[0093] Continue reading Figure 2 ,exist Figure 2 Under the experimental conditions in , the effective working area of ​​the drill bit cutting teeth refers to the projected area of ​​the contact surface between the drill bit cutting teeth 1 and the rock 2 in the plane with the cutting speed direction as the normal, and the axial force refers to the force exerted by the rock on the drill bit cutting teeth along the axial direction of the drill bit.

[0094] From the above formula (2), it can be seen that under the same rock-breaking axial force, The bigger, The larger it is, the stronger the ability of the drill bit cutting teeth to penetrate into the formation, that is, the greater the speed-increasing potential of the drill bit cutting teeth.

[0095] The following is an example of the process of testing the wear resistance of drill cutting teeth:

[0096] The wear resistance test of drill bit cutting teeth is a wet grinding test. During the test, the drill bit cutting teeth cut a circular granite ring (for example, the outer diameter of the granite ring is 1100 mm and the inner diameter is 280 mm) at a fixed back rake angle, cutting speed, cutting depth, and feed rate. One pass is counted as the drill bit cutting teeth from the outer ring to the inner ring of the granite ring. At this time, the drill bit cutting teeth move a distance of 567.5 m relative to the rock.

[0097] The wet grinding experiment was carried out on a vertical turret lathe with a cutting speed of 100 m / min, a feed rate of 1.57 mm / r, and a cutting depth of 0.5 mm. Clean water was used as the coolant to cool the PDC teeth. The wet grinding experiment was stopped after the drill bit cutting teeth moved on the rock surface 30 times. The ground surface area and wear volume of the drill bit cutting teeth were measured using a three-dimensional optical profilometer.

[0098] Figure 3 Schematic diagram of the wear resistance test results of the drill bit cutting teeth provided in the embodiment of the present application, as shown in Figure 3 As shown in FIG, the wear resistance of the drill bit cutting teeth is evaluated by the area or wear volume of the grinding area A. The larger the grinding area and wear volume of the grinding area A, the worse the wear resistance, and vice versa.

[0099] Figure 4 Schematic diagram of the impact test of the drill bit cutting teeth provided in the embodiment of the present application, as shown in FIG. Figure 4As shown, a progressive drop tester (PDT) was used to conduct impact tests on drill cutters, and the cutter's final failure energy (FFE) was used to evaluate its impact resistance. A drop hammer 8 precisely impacted the tip of each cutter 1 in the impact direction 7 (downward). Before testing, the cutter 1 was brazed to the tooth holder 6 using solder 5, ensuring a 15° inclination angle to simulate the impact of the cutter 1 downhole. During the test, a control system automatically controlled the release height of the drop hammer 8, ensuring that the drop hammer 8 impacted the cutter 1 with a preset impact energy. For example, the initial impact energy was 2 J, and the energy increased by 2 J with each subsequent impact. When the first crack appeared in the diamond layer 9 above the cutter 1, the corresponding impact energy was recorded as the initial cracking energy (ICE). When the fracture area of ​​the diamond layer 9 exceeds 30%, the drill cutter 1 is considered to have failed, and this impact energy is defined as the final failure energy. During the test, the ICE and FFE of each drill cutter 1 were recorded simultaneously. The greater the FFE, the higher the impact resistance of the drill cutter 1.

[0100] In summary, through various experiments, we can obtain the various performance indicators of drill bit cutting teeth under different parameters, and then use regression analysis or deep learning algorithm fitting to obtain the mapping relationship between the parameters of various types of drill bit cutting teeth and various performance indicators.

[0101] Optionally, based on the above four performance indicators, the rock breaking efficiency index - MSE, the speed increase potential index - K, the wear resistance index - ground area (or wear volume), and the impact resistance index - FFE can also be normalized to draw a multi-index evaluation diagram of the drill bit cutting teeth.

[0102] Figure 5 This is a schematic diagram of a multi-index evaluation diagram of a drill bit cutting tooth provided in an embodiment of the present application, as shown in FIG. Figure 5 As shown in the figure, by integrating the speed-up potential, rock-breaking efficiency, impact resistance and wear resistance indicators of different types of drill bit cutting teeth into the same figure, the performance of each tooth shape in different indicators can be intuitively displayed, which helps R&D personnel to quickly identify the performance shortcomings or advantages of the tooth shape and select special-shaped teeth with different performance according to the formation requirements.

[0103] S102. Generate design parameters for the target drill bit cutting teeth based on the type of the target drill bit cutting teeth, the expected performance indicators of the target drill bit cutting teeth, the expected performance type of the target drill bit cutting teeth, and the mapping relationship between parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth.

[0104] In the embodiments of the present application, the expected performance type matches the performance requirements of the target drill bit cutter, so that the designed target drill bit cutter can meet the actual requirements under specific formation conditions. The expected performance types of the target drill bit cutter may include: standard type, high performance type, wear-resistant type, impact-resistant type, etc.

[0105] In order to design the target drill bit cutter, it is possible to focus on a single key performance indicator or simultaneously consider and integrate multiple performance indicators based on the actual formation conditions and requirements. The expected performance type can be a single type or a combination of multiple types, and this application does not impose any specific restrictions on this.

[0106] It can be understood that when the mapping relationship between the parameters of various types of drill bit cutting teeth and various performance indicators is known, by inputting the type of target drill bit cutting teeth, expected performance indicators and expected performance type, design parameters that meet the above conditions can be automatically generated.

[0107] By way of example, a possible implementation is provided herein, specifically including: determining a mapping relationship between parameters of target drill bit cutting teeth and various performance indicators of target drill bit cutting teeth based on the type of target drill bit cutting teeth and the mapping relationship between parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth;

[0108] Determine the weight of each performance index of the target drill bit cutting tooth according to the expected performance type;

[0109] Based on the mapping relationship between the parameters of the target drill bit cutting teeth and the various performance indicators of the target drill bit cutting teeth, the expected performance indicators of the target drill bit cutting teeth and the weights of the various performance indicators of the target drill bit cutting teeth, the design parameters of the target drill bit cutting teeth are generated.

[0110] First, based on the target drill bit cutter type, the mapping relationships between the parameters of all drill bit cutter types and various performance indicators are obtained from the database. This allows the mapping relationship corresponding to the target drill bit cutter type to be extracted in a targeted manner.

[0111] Then, to meet the performance requirements of drill bit cutters in different formation conditions, the weights of each performance indicator of the target drill bit cutter can be determined based on the expected performance type. For example, when working in hard formations, the expected performance types may be impact resistance and wear resistance, in which case the impact resistance and wear resistance indicators each have a larger weight. When working in deep formations, the expected performance types may be speed-up potential and high performance, in which case the speed-up potential and rock-breaking efficiency indicators have a larger weight. In complex formations, the expected performance type should be selected to achieve a balance among all performance indicators, that is, the weights corresponding to each performance indicator can be equal.

[0112] Finally, based on the expected performance indicators of the target drill bit cutting teeth, the weights of various performance indicators and the known mapping relationships, the design parameters that can meet these requirements are reversely deduced.

[0113] Figure 6 The interface diagram of the design platform for the drill bit cutting teeth provided in the embodiment of the present application is as follows: Figure 6 As shown, the design platform responds to the user triggering the operation of dragging the performance indicator control (rock breaking efficiency, speed increase potential, wear resistance, impact resistance) to determine the expected performance indicators of the target drill bit cutting teeth, and responds to the user triggering the operation of clicking the preset solution control (standard type, high performance type, wear resistance type, impact resistance type) to determine the weights of various performance indicators of the target drill bit cutting teeth.

[0114] Once the target drill bit cutter type is determined to be an arched cutter, the design platform automatically generates the target drill bit cutter's design parameters, including geometric parameters (chamfer, back rake angle, side rake angle, tooth diameter) and material parameters (PDC layer thickness, diamond grit size, and cobalt content), based on the mapping relationship between the target drill bit cutter parameters and various performance indicators, as well as the expected performance indicators and the weights of each performance indicator. Furthermore, the design platform can generate a multi-index evaluation diagram for the target drill bit cutter and display it on the screen to intuitively demonstrate the performance of the target drill bit cutter's current tooth shape across different indicators.

[0115] Based on the above-mentioned design platform of the drill bit cutting teeth, an embodiment of the present application further provides an arched tooth with an arched ridge line. Figure 7 This is a schematic diagram of the structure of the arched teeth with arched ridges provided in an embodiment of the present application. Figure 8 for Figure 7 The main view, Figure 9 for Figure 7 Side view of Figure 10 for Figure 7 Top view of .

[0116] Under the expected performance indicators of (rock breaking efficiency: 85, speed increase potential: 75, wear resistance: 75, impact resistance: 85), the design parameters of the arched teeth with arched ridges generated by the above drill bit cutting tooth design platform are as follows:

[0117] Geometric parameters: (chamfer: 0.35 mm, back tilt angle: 15°, side tilt angle: 0°, tooth diameter: 19.05 mm);

[0118] Material parameters: (PCD layer thickness: 3 mm, diamond grain size: 15 μm, cobalt content: 10 vol.%).

[0119] See also Figures 7 to 10 The number of arched ridges 11 of the arched tooth 10 with arched ridges is 3, and the arched tooth combines the rock-breaking efficiency advantage of the axe-shaped tooth and the impact resistance advantage of the conical tooth, has balanced rock-breaking efficiency and impact resistance, and is suitable for drilling operations in gravel formations.

[0120] The embodiment of the present application provides a method for generating design parameters of drill bit cutting teeth, which obtains the mapping relationship between the parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth, wherein the parameters of the drill bit cutting teeth include the structural parameters and material parameters of the drill bit cutting teeth; based on the type of target drill bit cutting teeth, the expected performance indicators of the target drill bit cutting teeth, the expected performance type of the target drill bit cutting teeth, and the mapping relationship between the parameters of different types of drill bit cutting teeth and various performance indicators of the drill bit cutting teeth, the design parameters of the target drill bit cutting teeth are generated; this method comprehensively considers multiple performance indicators, and the generated parameters are more practical and targeted, thereby ensuring that the designed drill bit cutting teeth meet the performance requirements of different geological conditions.

[0121] In some embodiments, based on the mapping relationship between the parameters of the target drill bit cutting teeth and various performance indicators of the target drill bit cutting teeth, the expected performance indicators of the target drill bit cutting teeth, and the weights of various performance indicators of the target drill bit cutting teeth, the design parameters of the target drill bit cutting teeth are generated, including:

[0122] Determining the parameters of the target drill bit cutting teeth corresponding to the various performance indicators of the target drill bit cutting teeth based on a mapping relationship between the expected performance indicators and the parameters of the target drill bit cutting teeth and various performance indicators of the target drill bit cutting teeth;

[0123] The design parameters of the target drill bit cutting teeth are determined according to the weights of the various performance indicators of the target drill bit cutting teeth and the parameters of the target drill bit cutting teeth corresponding to the various performance indicators of the target drill bit cutting teeth.

[0124] In the embodiments of the present application, the parameters of the target drill bit cutting teeth that meet the conditions of each expected performance indicator are first calculated based on the mapping relationship between the known parameters of the target drill bit cutting teeth and various performance indicators, as well as the expected performance indicators. In other words, each expected performance indicator corresponds to a set of target drill bit cutting tooth parameters. Then, based on the weights of each performance indicator and the target drill bit cutting tooth parameters corresponding to each expected performance indicator, design parameters that meet the specific performance requirements are generated.

[0125] In this way, the parameters of the drill bit cutting teeth can be flexibly adjusted according to the drilling requirements of the actual formation working conditions using the weights of the performance indicators to obtain the target drill bit cutting teeth that adapt to different formation conditions.

[0126] For example, according to the weights of the various performance indicators of the target drill bit cutting teeth, the parameters of the target drill bit cutting teeth corresponding to the various performance indicators of the target drill bit cutting teeth may be weighted and summed to obtain the design parameters of the target drill bit cutting teeth.

[0127] Here, when each performance indicator is determined by multiple parameters, it is necessary to comprehensively calculate the final design parameters of the target drill bit cutting teeth. Specifically, the weight value of each performance indicator can be directly assigned to all its associated parameters.

[0128] For example, if the weight of the rock breaking efficiency index is a, then the weight of each parameter in the group corresponding to the rock breaking efficiency index is also a. Therefore, for each type of parameter, according to its weight and the parameter value in each group, the parameter is weighted and summed. For example, the chamfer value corresponding to the rock breaking efficiency index (weight a) is A, the chamfer value corresponding to the impact resistance index (weight b) is B, the chamfer value corresponding to the wear resistance index (weight c) is C, and the chamfer value corresponding to the speed-up potential index (weight d) is D. When determining the final value of the chamfer value design parameter, the chamfer value is weighted and summed according to the above weight values ​​and the corresponding parameter values. The final chamfer value is Finally, the weighted sum of the parameters is summarized to generate the final design parameter combination.

[0129] In this way, based on the weight differences of different performance indicators, design parameters that meet the preset performance indicator requirements can be generated, thereby improving the comprehensive performance of the target drill bit cutting teeth in application scenarios that require balancing multiple performance indicators.

[0130] In other embodiments, based on the mapping relationship between the parameters of the target drill bit cutting teeth and the various performance indicators of the target drill bit cutting teeth, the expected performance indicators of the target drill bit cutting teeth, and the weights of the various performance indicators of the target drill bit cutting teeth, the design parameters of the target drill bit cutting teeth are generated, including:

[0131] Based on the weights of the various performance indicators of the target drill bit cutting teeth, a weighted sum of the differences between the various performance indicators of the target drill bit cutting teeth and corresponding items in the expected performance indicators is determined as an objective function;

[0132] Based on the mapping relationship between the parameters of the target drill bit cutting teeth and various performance indicators of the target drill bit cutting teeth, the parameters of the target drill bit cutting teeth are determined by an optimization method with minimizing the objective function as the optimization goal.

[0133] In an embodiment of the present application, the problem of reversely deducing the mapping relationship between the parameters of the target drill bit cutting teeth and various performance indicators to obtain the design parameters is converted into a multi-objective optimization problem, that is, finding a set of design parameters of the target drill bit cutting teeth so that the various performance indicators of the target drill bit cutting teeth determined based on the above mapping relationship are as close as possible to the corresponding items in the expected performance indicators.

[0134] For example, the parameters of the target drill bit cutting teeth and various performance indicators The mapping relationship between them is .

[0135] Based on this, the objective function It can be expressed as the following formula (3):

[0136]

[0137] in, is the expected performance indicator, The first cutter of the target drill bit The difference between the value of the performance indicator and the value of the expected performance indicator is measured. For the The weight of each performance indicator, is the number of performance indicators.

[0138] To minimize the objective function To optimize the target, use optimization algorithms such as genetic algorithm, particle swarm optimization algorithm, gradient descent method, etc. to solve the optimal solution. As the parameters of the target drill bit cutting teeth.

[0139] In this way, a scientific and systematic method is provided for the parameter optimization of the drill bit cutting teeth, which not only improves the design efficiency of the target drill bit cutting teeth, but also improves the quality of the parameters generated for the target drill bit cutting teeth.

[0140] Optionally, the method further includes:

[0141] Detecting the true values ​​of various performance indicators of the target drill bit cutting teeth generated according to the design parameters of the target drill bit cutting teeth;

[0142] Based on the difference between the actual value of each performance index of the target drill bit cutting tooth and the expected performance index, the mapping relationship between the parameters of the target drill bit cutting tooth and each performance index of the target drill bit cutting tooth is updated.

[0143] Understandably, since the mapping relationship between target drill cutter parameters and various performance indicators is typically based on theoretical models, empirical formulas, and experimental data, it may have certain limitations. Therefore, to improve the performance prediction accuracy and optimization effect of the target drill cutter, it is necessary to update the mapping relationship between parameters and performance indicators based on the difference between the actual performance indicators of the target drill cutter and the expected performance indicators, thereby reducing the deviation between the mapping relationship and the actual situation.

[0144] The process of detecting the true value of each performance index of the target drill bit cutting teeth can refer to the above Figures 2 to 4 The detection process in the embodiment is not described in detail here. The actual performance indicators obtained by detection are compared with the corresponding expected performance indicators, and the difference between them is calculated to correct the parameters or function form in the mapping relationship, thereby re-fitting and generating a new mapping relationship.

[0145] In the embodiment of the present application, the reliability and accuracy of the mapping relationship between the parameters of the target drill bit cutting teeth and various performance indicators are improved by updating the mapping relationship.

[0146] Based on the above embodiments, an embodiment of the present application further provides a device for generating design parameters of drill cutting teeth.
