Description

Technical Field

[0001] This invention relates to the field of oil and gas drilling and completion technology, and in particular to a method and apparatus for analyzing drill bit matching degree. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] During drilling operations, the drill bit is the primary tool for breaking rocks. The duration of a drilling operation depends not only on the characteristics of the rock formation being drilled and the performance of the drill bit itself, but also, and perhaps more importantly, on the compatibility between the drill bit and the formation. Therefore, the appropriate selection of the drill bit plays a crucial role in improving drilling efficiency and achieving cost reduction and efficiency gains.

[0004] Currently, rock drillability tests can be used to analyze the drillability grade of rocks, and then a suitable drill bit type can be matched based on the drillability grade. However, this requires sophisticated equipment, and rock samples need to be transported from the work site to a laboratory with testing capabilities for analysis, which is costly. Therefore, to save costs, the matching degree of used drill bits can be analyzed. However, existing technologies for analyzing used drill bits are relatively one-sided in terms of both the drill bit parameters and the analysis conditions, resulting in low accuracy of the analysis results. This makes it impossible to comprehensively and accurately analyze the matching degree of drill bits, leading to low drilling efficiency and failing to achieve the goal of cost reduction and efficiency improvement.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0026] In the description of this specification, the terms "comprising," "including," "having," and "containing" are open-ended terms, meaning that they include but are not limited to. The terms "an embodiment," "a specific embodiment," "some embodiments," and "for example," etc., refer to specific features, structures, or characteristics described in connection with that embodiment or example that are included in at least one embodiment or example of this application.

The order of steps involved in the various embodiments is used to illustrate the implementation of this application, and the order of steps is not limited and can be adjusted appropriately as needed.

[0027] Research has shown that during drilling operations, drill bits with a high degree of formation compatibility can reduce drilling and completion cycles by increasing the rate of penetration (RLP), ultimately lowering overall drilling costs. However, current methods for analyzing drill bit compatibility are somewhat one-sided in terms of both the drill bit parameters and the analytical conditions used, resulting in low accuracy and an inability to comprehensively and accurately analyze the degree of drill bit compatibility. This leads to low drilling efficiency and fails to achieve the goal of cost reduction and efficiency improvement.

[0028] Therefore, embodiments of the present invention provide a drill bit matching degree analysis method and apparatus, which can analyze drill bit usage data through multiple drill bit analysis indicators, and determine the matching degree relationship between each type of drill bit and different thicknesses of the drilled section based on the correlation between multiple drill bit analysis indicators and the thickness of the drilling section. This can quantify the drilling cost data of drilling sections of different thicknesses, thereby obtaining comprehensive and accurate drill bit matching degree analysis results, providing a stronger basis for drill bit selection, and achieving the goal of cost reduction and efficiency improvement.

[0029] like Figure 1 The diagram shows a flowchart of a drill bit matching degree analysis method provided by an embodiment of the present invention. The method may include the following steps:

[0030] Step 101: Obtain historical drilling data for the drilling section to be analyzed. The historical drilling data includes usage data for multiple drill bits; wherein, the usage data for multiple drill bits are usage data for different types of drill bits.

[0031] Step 102: Based on multiple predefined drill bit analysis indicators and multiple drill bit usage data, determine the corresponding indicator values ​​for multiple drill bit analysis indicators for each type of drill bit; the multiple drill bit analysis indicators include the average footage of each type of drill bit, the average mechanical drilling speed of each type of drill bit, the average number of tripping in and out of the hole for each type of drill bit, the average unit price of each type of drill bit, the average tripping in and out of the hole speed of each type of drill bit, and the average comprehensive drilling day cost of each type of drill bit.

[0032] Step 103: Based on the predefined correlation between multiple drill bit analysis indicators and the thickness of the drilling section, and the index values ​​corresponding to the multiple drill bit analysis indicators for each type of drill bit, determine the matching degree relationship between each type of drill bit and different thicknesses of the drilling section to be analyzed; the correlation between the multiple drill bit analysis indicators and the thickness of the drilling section is used to represent the comprehensive drilling cost data of drilling sections with different thicknesses.

[0033] Step 104: Determine the matching degree between each type of drill bit and the specified thickness of the well section to be analyzed, based on the matching degree relationship between each type of drill bit and the different thicknesses of the well section to be analyzed.

[0034] In this embodiment of the invention, historical drilling data of the well section to be analyzed is acquired, including multiple drill bit usage data; wherein, the multiple drill bit usage data are usage data of different types of drill bits; based on multiple predefined drill bit analysis indicators and the multiple drill bit usage data, the indicator values ​​corresponding to multiple drill bit analysis indicators for each type of drill bit are determined; the multiple drill bit analysis indicators include the average footage of each type of drill bit, the average mechanical speed of penetration of each type of drill bit, the average number of trips and pulls of each type of drill bit, the average unit price of each type of drill bit, and the average tripping and pull-out speed of each type of drill bit. The average comprehensive drilling day cost for each type of drill bit; based on the predefined correlation between multiple drill bit analysis indicators and the thickness of the drilling section, and the corresponding indicator values ​​of multiple drill bit analysis indicators for each type of drill bit, the matching degree relationship between each type of drill bit and different thicknesses of the drilling section to be analyzed is determined; the correlation between the multiple drill bit analysis indicators and the thickness of the drilling section is used to represent the comprehensive drilling cost data of drilling sections of different thicknesses; based on the matching degree relationship between each type of drill bit and different thicknesses of the drilling section to be analyzed, the matching degree between each type of drill bit and a specified thickness of the drilling section to be analyzed is determined. Compared with existing technologies that analyze the matching degree of used drill bits, this method analyzes drill bit usage data using multiple drill bit analysis indicators. Based on the predefined correlation between these indicators and the thickness of the well section, it determines the matching degree between each type of drill bit and different thicknesses of the well section to be analyzed. This allows for the quantification of drilling cost data at different thicknesses of the well section to be analyzed, resulting in accurate and comprehensive drill bit matching degree analysis results. Consequently, it can improve drilling efficiency while saving costs, achieving the goal of cost reduction and efficiency improvement.

[0035] In step 101 above, historical drilling data of the well section to be analyzed can be collected.

[0036] Historical drilling data may include usage data for multiple drill bits; this usage data may be usage data for different types of drill bits.

[0037] In this embodiment of the invention, the data used for each drill bit may include drill bit type data, mechanical drilling speed data, footage data, unit price data, tripping times data, tripping speed data, and comprehensive drilling day cost data, etc.

[0038] In step 102 above, the index values ​​corresponding to multiple drill bit analysis indicators for each type of drill bit can be determined based on multiple predefined drill bit analysis indicators and multiple drill bit usage data.

[0039] Among them, the aforementioned drill bit analysis indicators may include the average footage per minute for each type of drill bit, the average mechanical drilling speed for each type of drill bit, the average number of trips in and out of the well for each type of drill bit, the average unit price for each type of drill bit, the average tripping in and out speed for each type of drill bit, and the average comprehensive drilling day cost for each type of drill bit.

[0040] In this embodiment of the invention, step 102 may specifically include:

[0041] Classify multiple drill bit usage data based on the drill bit type data in each drill bit usage data;

[0042] Based on the mechanical drilling speed data, footage data, unit price data, tripping times data, tripping speed data, and comprehensive drilling day cost data from multiple drill bit usage data for each type of drill bit, calculate the corresponding index values ​​for the average footage, average mechanical drilling speed, average tripping times, average unit price, average tripping speed, and average comprehensive drilling day cost for each type of drill bit.

[0043] In this way, by calculating the index values ​​corresponding to multiple drill bit analysis indicators for each type of drill bit, we can determine the comprehensive index parameters of each type of drill bit in multiple aspects, providing data support for subsequent multi-angle analysis of the matching degree of drill bits, thereby improving the comprehensiveness and accuracy of the analysis results.

[0044] It should be noted that the average tripping speed and average comprehensive drilling cost for each type of drill bit are independent of the drill bit type. Their corresponding index values ​​can be considered constant. In other words, in the well section to be analyzed, the average tripping speed and average comprehensive drilling cost for each type of drill bit are the same.

[0045] In step 103 above, the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed can be determined based on the predefined correlation between multiple drill bit analysis indicators and the thickness of the well section, as well as the index values ​​corresponding to the multiple drill bit analysis indicators of each type of drill bit.

[0046] Among them, the correlation between the above-mentioned drill bit analysis indicators and the thickness of the drilled section is used to represent the comprehensive drilling cost data for drilled sections of different thicknesses.

[0047] In this embodiment of the invention, the above-mentioned comprehensive drilling cost data may include drill bit cost data, comprehensive drilling expense data, and comprehensive tripping and tripping expense data.

[0048] In practice, during drilling operations, the costs and operational efficiency of each type of drill bit vary depending on the thickness of the well section. Therefore, by analyzing the correlation between multiple drill bit analysis indicators and the thickness of the well section, the drilling cost data for well sections of different thicknesses can be quantified, leading to more accurate analysis results. Specifically, in this embodiment of the invention, the correlation between multiple drill bit analysis indicators and the thickness of the well section is used to quantify the drilling cost data into three aspects: drill bit cost data, comprehensive drilling cost data, and comprehensive tripping and running-in cost data.

[0049] In this embodiment of the invention, the above-mentioned drill bit cost data can be determined based on two drill bit analysis indicators: the average footage of each type of drill bit and the average unit price of each type of drill bit, along with the thickness of the drilling section.

[0050] The comprehensive drilling cost data can be determined based on two drill bit analysis indicators: the average mechanical drilling rate for each type of drill bit and the average comprehensive drilling day cost for each type of drill bit, along with the thickness of the drilled well section.

[0051] The comprehensive cost data for tripping in and out of the well can be determined based on four drill bit analysis indicators: average tripping in and out speed for each type of drill bit, average footage advanced for each type of drill bit, average number of tripping in and out of the well for each type of drill bit, and average comprehensive drilling day cost for each type of drill bit.

[0052] In practice, the above drill bit cost data can be expressed by the following formula 1:

[0053]

[0054] Where ω1 is the drill bit cost, Z is the drilling section thickness, X is the average footage of each type of drill bit, and C is the average unit price of each type of drill bit.

[0055] In practice, the above-mentioned comprehensive drilling cost data can be expressed by the following formula 2:

[0056]

[0057] Where ω2 is the overall drilling cost, Z is the drilling section thickness, V is the average mechanical drilling rate for each type of drill bit, and P is the average overall drilling day cost for each type of drill bit.

[0058] In practice, the above-mentioned combined tripping and running costs can be expressed by the following formula 3:

[0059]

[0060] Where ω3 is the combined tripping cost, X is the average footage per second for each type of drill bit, Y is the average tripping speed for the drilling section, P is the average daily drilling cost for each type of drill bit, and N is the average number of tripping operations for each type of drill bit.

[0061] Simplifying Formula 3, we get Formula 4:

[0062]

[0063] The average number of trips and runs for each type of drill bit can also be determined based on the average footage drilled and the thickness of the drilled section for each type of drill bit; that is, N can also be expressed as... Therefore, Formula 4 above can also be replaced by Formula 5 below:

[0064]

[0065] In practice, the aforementioned comprehensive drilling cost data (i.e., the correlation between multiple drill bit analysis indicators and the thickness of the drilled section) can be the sum of drill bit cost data ω1, comprehensive drilling expense data ω2, and comprehensive tripping and running-out expense data ω3. Specifically, by adding the above formulas 1, 2, and 5 (or 4), we obtain formula 6:

[0066] or

[0067]

[0068] In this embodiment of the invention, the correlation between multiple drill bit analysis parameters and the thickness of the drilled section can be expressed in the form of Formula 6.

[0069] In practice, the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed can be determined according to Formula 6 and the index values ​​corresponding to multiple drill bit analysis indicators for each type of drill bit.

[0070] In this embodiment of the invention, the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed can be represented in the form of a data table or in the form of a graph.

[0071] Specifically, for each type of drill bit, the calculated index values ​​corresponding to each drill bit analysis index are substituted into Formula 6 above to obtain the comprehensive drilling cost function formula for each type of drill bit in the well section to be analyzed. Based on the comprehensive drilling cost function formula for each type of drill bit, a matching degree relationship diagram is plotted between each type of drill bit and different thicknesses of the well section to be analyzed (i.e., the comprehensive drilling cost of each type of drill bit for well sections of different thicknesses to be analyzed). Alternatively, based on the comprehensive drilling cost function formula for each type of drill bit, the comprehensive drilling cost ω at different thicknesses Z of the well section to be analyzed is calculated, and each thickness Z and its corresponding comprehensive drilling cost ω are recorded in the form of a data table.

[0072] In step 104 above, the matching degree between each type of drill bit and the specified thickness of the well section to be analyzed can be determined based on the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed.

[0073] In this embodiment of the invention, step 104 may specifically include:

[0074] Based on the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed, obtain the comprehensive drilling cost data corresponding to each type of drill bit at a specified thickness of the well section to be analyzed.

[0075] Sort the comprehensive drilling cost data for each type of drill bit at a specified thickness in the well section to be analyzed in ascending order;

[0076] Based on the sorting results, determine the matching degree between each type of drill bit and the specified thickness of the well section to be analyzed.

[0077] In practice, the smaller the comprehensive drilling cost data at a specified thickness in the well section to be analyzed, the higher the degree of matching between this type of drill bit and the specified thickness in the well section to be analyzed.

[0078] In this way, by comparing the matching degree between each type of drill bit and different thicknesses of the well section to be analyzed, the optimal drill bit type for different thicknesses of the well section to be analyzed can be more clearly identified, thereby improving the efficiency of drill bit selection and achieving the goal of reducing costs and increasing efficiency.

[0079] To more clearly explain the drill bit matching degree analysis method provided in the embodiments of the present invention, a specific example is provided below. Figure 1 The drill bit matching analysis method shown is further explained in detail.

[0080] In a certain block, the primary target layer is layer M (the drilling section to be analyzed). This stratum is buried at a depth of approximately 2500m-3000m, and its lithology is mainly composed of interbedded sandstone and shale, with occasional conglomerate. Long-term tectonic compaction has resulted in low rock-breaking efficiency, short drilling depth, and high drill bit consumption during drilling in this stratum. The drill bit matching degree analysis method provided in this embodiment of the invention is used to analyze the drill bit matching degree of this stratum, which mainly includes the following steps:

[0081] 1. Data Collection

[0082] Collect the drilling history (historical drilling data) of wells drilled from 2016 to 2021 at the work site, determine the thickness Z of the M layer, calculate the average footage X, average mechanical drilling speed V, average tripping times N, average unit price C, average tripping speed Y, and average comprehensive drilling day cost P of the study area, as shown in Table 1 (taking five types of drill bits A, B, C, D, and E as examples).

[0083] Table 1. Statistical Table of Drilling Data for Different Types of Drill Bits

[0084]

[0085] 2. Based on the collected drilling data (as shown in Table 1) and the comprehensive drilling cost formula (i.e., the correlation between multiple drill bit analysis indicators and the thickness of the drilled section): Determine the comprehensive drilling cost function formula for different types of drill bits (as shown in Table 2).

[0086] Table 2. Comprehensive Drilling Cost Function Formulas for Different Types of Drill Bits

[0087]

[0088]

[0089] 3. Based on the comprehensive drilling cost function formulas for different types of drill bits, plot comprehensive drilling cost curves for different types of drill bits. The horizontal axis represents the thickness Z of the target layer, and the vertical axis represents the comprehensive drilling cost ω, as shown below. Figure 2 The figure shows the comprehensive drilling cost curves for five types of drill bits: A, B, C, D, and E (the figure represents the matching degree between each type of drill bit and different thicknesses of the well section to be analyzed).

[0090] 4. Optimize drill bit selection based on the comprehensive drilling cost curves for different types of drill bits.

[0091] Selecting a target layer with a specified thickness (assuming the specified thickness Z is 1500m), the overall drilling cost and optimization results are as follows: Figure 3(The relationship between each type of drill bit and the matching degree at a specified thickness is shown in the figure) and Table 3 (the relationship between each type of drill bit and the matching degree at a specified thickness is shown in the data table).

[0092] Alternatively, you can substitute the data from Table 1 into the formula: Calculate the overall drilling cost for different types of drill bits.

[0093] Table 3. Comprehensive drilling costs for different types of drill bits (taking a target formation thickness of 1500m as an example)

[0094] Serial Number Drill bit type Total drilling cost ($) 1 A 1556774.94 2 B 1551533.19 3 C 1376223.43 4 D 370160.98 5 E 320767.51

[0095] The lower the overall drilling cost, the more economical and suitable the drill bit is. The E drill bit has the best overall drilling cost of $320,767.51. Therefore, in this study area, when the target layer thickness is specified as 1500m, E is the optimal drill bit.

[0096] In summary, the drill bit matching degree analysis method of the present invention has the following beneficial effects:

[0097] 1. It comprehensively considers data such as the thickness of the well section to be analyzed, the mechanical drilling speed of the drill bit, the footage, the cost, the number of trips in and out of the well, the trip speed in and out of the well, and the comprehensive drilling day cost. It uses three cost data, namely drill bit cost data, comprehensive drilling cost data, and comprehensive trip cost data, as a bridge to link these data together. With the comprehensive drilling cost as the final evaluation standard, it intuitively determines the optimal drill bit type suitable for the specified thickness of the block.

[0098] 2. The drill bit matching degree analysis method in this embodiment of the invention has the characteristics of requiring few parameters that are easy to obtain, has a wide range of applications, is easy to calculate, has no equipment requirements, and is suitable for various reservoirs and multiple production conditions. It plays an important role in improving drilling operation efficiency and achieving cost reduction and efficiency improvement.

[0099] This invention also provides a drill bit matching degree analysis device, as described in the following embodiments. Since the principle by which this device solves the problem is similar to that of the drill bit matching degree analysis method, the implementation of this device can refer to the implementation of the drill bit matching degree analysis method; repeated details will not be elaborated further.

[0100] like Figure 4 The diagram shown is a schematic of a drill bit matching degree analysis device provided in an embodiment of the present invention. The device may include:

[0101] The data acquisition module 401 is used to acquire historical drilling data of the drilling section to be analyzed. The historical drilling data includes multiple drill bit usage data; wherein, the multiple drill bit usage data are usage data of different types of drill bits.

[0102] The index value determination module 402 is used to determine the index values ​​corresponding to multiple drill bit analysis indicators for each type of drill bit based on multiple predefined drill bit analysis indicators and multiple drill bit usage data; the multiple drill bit analysis indicators include the average footage of each type of drill bit, the average mechanical drilling speed of each type of drill bit, the average number of trips and starts of each type of drill bit, the average unit price of each type of drill bit, the average trip and start speed of each type of drill bit, and the average comprehensive drilling day cost of each type of drill bit.

[0103] The matching degree determination module 403 is used to determine the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed based on the predefined correlation between multiple drill bit analysis indicators and the thickness of the well section, as well as the index values ​​corresponding to the multiple drill bit analysis indicators of each type of drill bit; the correlation between the multiple drill bit analysis indicators and the thickness of the well section is used to represent the comprehensive drilling cost data of well sections with different thicknesses.

[0104] The matching degree analysis module 404 is used to determine the matching degree between each type of drill bit and a specified thickness of the well section to be analyzed, based on the matching degree relationship between each type of drill bit and different thicknesses of the well section to be analyzed.

[0105] In this embodiment of the invention, the data used for each drill bit may include drill bit type data, mechanical drilling speed data, footage data, unit price data, tripping times data, tripping speed data, and comprehensive drilling day cost data.

[0106] In this embodiment of the invention, the index value determination module 402 can be specifically used for:

[0107] Classify multiple drill bit usage data based on the drill bit type data in each drill bit usage data;

[0108] Based on the mechanical drilling speed data, footage data, unit price data, tripping times data, tripping speed data, and comprehensive drilling day cost data from multiple drill bit usage data for each type of drill bit, calculate the corresponding index values ​​for the average footage, average mechanical drilling speed, average tripping times, average unit price, average tripping speed, and average comprehensive drilling day cost for each type of drill bit.

[0109] In this embodiment of the invention, the comprehensive drilling cost data may include drill bit cost data, comprehensive drilling expense data, and comprehensive tripping cost data;

[0110] The drill bit cost data can be determined based on two drill bit analysis indicators: the average footage and the average unit price of each type of drill bit, along with the thickness of the drilled well section.

[0111] The comprehensive drilling cost data can be determined based on two drill bit analysis indicators: the average mechanical drilling rate for each type of drill bit and the average comprehensive drilling day cost for each type of drill bit, along with the thickness of the drilled well section.

[0112] The comprehensive tripping and running cost data can be determined based on four drill bit analysis indicators for each type of drill bit: average tripping and running speed, average footage advanced by each type of drill bit, average number of tripping and running operations by each type of drill bit, and average comprehensive drilling day cost for each type of drill bit. The average number of tripping and running operations by each type of drill bit is determined based on the average footage advanced by each type of drill bit and the thickness of the drilled section.

[0113] In this embodiment of the invention, the matching degree determination module can also be used to: calculate the correlation between multiple drill bit analysis indicators and the thickness of the drilled well section according to the following formula:
