The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] The present invention provides a method for optimizing drill bit parameters, which is described below.

[0048] Figure 1 A flow chart of an embodiment of a drill bit parameter optimization method provided by the present invention is shown in FIG. Figure 1 As shown, a drill bit parameter optimization method includes:

[0049] S101, obtaining drilling data of the produced oil wells in the target oil field, and determining several different types of preliminary selected drill bits based on the drilling data, wherein the drilling data includes the blockages in the produced oil wells and the parameters of the drill bits used in the operation;

[0050] It should be noted that based on the exploration data and the empirical method, several suitable models of drill bits are preliminarily selected for a certain blockage to achieve preliminary screening of the drill bits.

[0051] S102, obtaining evaluation indicators of different types of preliminarily selected drill bits determined based on the drilling test for drilling out different blockages under different working parameters;

[0052] It should be noted that the drilling test specifically involves installing the preliminary selected drill bit on the matching power drill and fixing it on a low drilling pressure drilling and grinding comprehensive simulation test bench through a clamping device to drill out a rectangular target made of blockage, and starting the drilling test with the set drilling pressure and drilling speed.

[0053] It should also be noted that the test bench detection system consists of a torque and speed integrated sensor, an axial force sensor, a flow meter, a pressure sensor, a Siemens PLC, an AI4-20MA analog quantity acquisition module, a computer, a data acquisition card, and measurement and control software, which can collect the required data in real time during the drilling test.

[0054] S103. Based on the evaluation index, determine the preliminary drill bit models and candidate sequences of working parameters corresponding to different blockages in the target oil field.

[0055] It should be noted that the working parameters include drilling pressure and drilling speed.

[0056] Compared with the prior art, the present invention analyzes the differences in drilling effects of different drill bits on different blockages at different drilling pressures and rotation speeds through drilling tests, and gives recommended drill bit models and working parameters for the corresponding blockages, changing the situation in which traditional on-site drilling operations use only empirical methods, resulting in unsatisfactory drilling effects.

[0057] Considering that when performing unblocking operations, excessive output torque of the drill tool matched with the drill bit may damage the drill tool and make it unable to work normally, in some embodiments, the working parameters under the condition that the drill tool cannot work normally are screened out, such as Figure 2As shown, step S102 specifically includes:

[0058] S201, based on the drilling test, obtaining the output torque of the drill tool for drilling different blockages with different types of preliminarily selected drill bits under different working parameters;

[0059] S202, determining whether the output torque of the drilling tool is greater than a first threshold;

[0060] S203, when the output torque of the drilling tool is greater than the first threshold, excluding the working parameters;

[0061] S204: When the output torque of the drilling tool is not greater than the first threshold, determining an evaluation index of the preliminarily selected drill bit for drilling out the blockage under the working parameters.

[0062] It should be noted that the first threshold is the torque curve when the drilling tool works normally.

[0063] It should also be noted that, through real-time collection and judgment of data such as drill tool output torque, if the drill tool output torque during drilling is significantly greater than the torque curve of this type of drill tool during normal operation, the drilling test is stopped and the working parameters are excluded.

[0064] Furthermore, considering that too small mechanical specific energy will affect the drilling efficiency of oil and gas wells, in some embodiments, the working parameters with too small mechanical specific energy will be screened out for a second time, referring to Figure 3 , step S204 includes:

[0065] S301, when the output torque of the drilling tool is not greater than a first threshold, determining the mechanical specific energy of the preliminarily selected drill bit for drilling out the blockage under the working parameters;

[0066] S302, determining whether the mechanical specific energy is lower than a second threshold;

[0067] S303, when the mechanical specific energy is not lower than the second threshold, excluding the working parameters;

[0068] S304: When the mechanical specific energy is lower than the second threshold, determining an evaluation index of the primary selected drill bit for drilling out the blockage under the working parameters.

[0069] It should be noted that the second threshold value is 4 times the compressive strength of the blockage. If the mechanical specific energy is within 4 times the compressive strength of the blockage, it indicates that the drilling energy utilization is large and the efficiency is high.

[0070] Considering that the blockage debris will settle under the action of gravity and easily form a cuttings bed, the existence of the cuttings bed will cause a series of drilling problems, such as drilling resistance, high torque, and rear jamming. The smaller the diameter of the cuttings, the slower the settling rate. Therefore, in some embodiments, the evaluation index includes the size of the cuttings.

[0071] It should be noted that if Figure 4As shown, the cuttings size can be determined by the following experimental process:

[0072] S401, performing a drilling test on the blockage by using a preliminarily selected drill bit with given working parameters;

[0073] S402, collecting the rock cuttings obtained after each test and determining the size of the rock cuttings through a sieve.

[0074] It is also considered that the mechanical drilling speed is expressed as the drilling depth per unit pure drilling time, which directly reflects the speed of drilling of the drill bit. In some embodiments, the evaluation index also includes the mechanical drilling speed. Correspondingly, step S103 specifically includes: calculating a comprehensive score based on the evaluation index, and determining a preliminary selection of drill bit models and a candidate sequence of working parameters corresponding to different blockages in the target oil field based on the comprehensive score;

[0075] The formula for calculating the comprehensive score is:

[0076]

[0077] In the formula, represents the comprehensive score, Indicates mechanical drilling speed, represents the average diameter of drill cuttings, Indicates the mechanical drilling speed weight value, Indicates the average diameter weight of drill cuttings.

[0078] It should be noted that five levels, namely poor, relatively poor, medium, relatively good and good, are determined based on the comprehensive score, and a comprehensive comparison is performed to determine the drill bit model and recommended working parameters suitable for a certain blockage.
