Description

Technical Field

[0001] The present invention belongs to but is not limited to the technical field of pumping unit indicator diagram learning methods, and in particular relates to a creative learning method and system for a pumping unit indicator diagram. Background Art

[0002] Diagnosis of the dynamometer diagram is an essential skill for oilfield technicians to maintain the life of oil wells. It has become the leading technology for the development of low-permeability oil and gas fields. If the diagnosis is inaccurate, it will cause damage to the oil well reservoir, wellbore, etc., increase maintenance costs, and reduce recovery rates. Therefore, in order to improve the technicians' diagnostic dynamometer diagram skills, this kind of image memory method is specially developed. The traditional theoretical dynamometer diagram does not have a dynamic diagram demonstration, no mnemonics, no combination with the theoretical site, and no cases. It is generally difficult for trainees to understand and master it. Technicians generally feel "headache" when they see the pumping unit dynamometer diagram. With this set of simple and easy-to-learn methods, diagnosis is easy, the accuracy of the diagnostic dynamometer diagram is improved, and manpower and financial resources are saved for the later development of the oil field, laying the foundation for the sustainable development of the oil field.

[0003] The technical problems existing in the industrial application of existing technologies mainly include the following:

[0004] 1. Difficulty in understanding: The content of the traditional theoretical dynamometer diagram is relatively abstract and complex, lacking dynamic demonstration and intuitive case analysis, which makes it difficult for technicians, especially novices, to understand the form and meaning of the dynamometer diagram, affecting their accurate judgment of the oil well status.

[0005] 2. High learning difficulty: Due to the lack of full integration with actual on-site operations, traditional dynamometer diagram teaching lacks a visual and concrete learning method, which makes it difficult for technicians to effectively master diagnostic skills, thereby increasing the time cost of learning and mastering.

[0006] 3. Low diagnostic accuracy: Since traditional teaching methods cannot provide sufficient practical experience and memory skills, technicians often find it difficult to quickly and accurately diagnose the dynamometer diagram during field work, which leads to incorrect maintenance decisions on oil wells, thereby damaging key parts such as the oil well reservoir and wellbore.

[0007] 4. Lack of case support: Traditional dynamometer diagram teaching lacks the combination of actual case analysis and on-site operation, which makes it impossible for technicians to effectively apply theoretical knowledge in actual operations, increasing the risk of technical errors.

[0008] The existence of these problems not only reduces the recovery rate of the oil field, but also increases the cost of equipment inspection and maintenance, affecting the sustainable development of the oil field. Therefore, in response to these problems, it is urgent to develop a more intuitive, easy-to-learn and accurate dynamometer diagram diagnosis method to improve the diagnostic ability of technicians and the efficiency of oil field maintenance. Summary of the invention

[0009] In view of the problems existing in the prior art, the present invention provides a creative learning method for a pumping unit indicator diagram.

[0010] The present invention is implemented as follows: an intelligent dynamometer diagram training system for oilfield technicians training comprises the following functional modules:

Through visual path display and dynamic demonstration, it helps learners understand the motion path in each stroke and its corresponding working state;

[0014] d) Fault diagnosis simulation module: used to simulate different fault scenarios and display fault characteristics through changes in the shape of the indicator diagram.

[0016] f) Learning progress tracking module: used to record students' learning progress, test results and exercise scores, and generate personalized learning reports to help students and training managers understand their learning progress and weak links, so as to strengthen the training content in a targeted manner.

[0017] Furthermore, a creative learning method for the oil pumping unit indicator diagram was adopted, including a creative diagram of the theoretical indicator diagram, in which the red ball rolls back and forth on the four sides of the parallelogram, which actually means that the oil pump is doing reciprocating motion; an innovative memory method for the theoretical indicator diagram was invented, including the meaning of points, lines and surfaces, the mnemonics method, the four point diagonal memory method, and the four line side memory method.

[0018] Furthermore, the one surface, parallelogram ABCD, represents the work done by the oil pump in one stroke; the one ball, using a visual understanding and memory method, the red ball rolls back and forth on the four sides of the parallelogram, which actually refers to the reciprocating motion of the oil pump.

[0019] Furthermore, the four-point diagonal memory method is as follows: point A is the lower dead center, point C is the upper dead center, point B is the loading end point, and point D is the unloading end point.

[0020] Furthermore, the four-line edge memory method includes two strokes, an upstroke ABC, and a downstroke CDA.

[0021] Furthermore, the influencing factors are: first, human factors, second, ground equipment, third, downhole tools, and fourth, geological factors:

[0022] (1) Main measurement factors of human factors, operation specifications and accuracy;

[0023] (2) The impact of vibration of the pumping unit;

[0024] (3) The impact of vibration caused by downhole tools, sand jams, wax jams, etc. in the oil pump;

[0025] (4) Geological factors, such as sand production from strata, etc., which cause vibrations.

[0026] The present invention also proposes a creative learning system for the oil pump indicator diagram, characterized in that the system includes: an indicator diagram simulation module, which is used to visualize the theoretical indicator diagram as a parallelogram ABCD, and simulate the reciprocating motion of the oil pump through an animation demonstration of a red ball rolling on the four sides of the parallelogram, so as to help users understand the motion trajectory and indicator diagram characteristics of the oil pump in actual operation.

[0027] Furthermore, the system also includes: a memory auxiliary module, which is used to display the four vertices of the parallelogram ABCD through the four-point diagonal memory method, and the vertices respectively represent the key movement positions of the oil pump, where point A is the bottom dead center, point C is the top dead center, point B is the loading end point, and point D is the unloading end point, and helps users to perform systematic memory through visualization means.

[0028] Furthermore, the system further includes: a stroke analysis module, which is used to correspond the four sides of the parallelogram ABCD to the upstroke ABC and the downstroke CDA of the oil pump respectively, and help the user understand the working process and movement path of the oil pump in each stroke through animation or interactive demonstration.

[0029] Furthermore, the system also includes: an influencing factor analysis module, which is used to systematically analyze the main factors affecting the dynamometer diagram, including: human factors, ground equipment, downhole tools and geological factors, and demonstrate the impact of these factors on the dynamometer diagram in combination with actual cases to help users identify and troubleshoot faults in actual operations.

[0030] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0031] First, the present invention provides a creative learning method for the pumping unit indicator diagram, which is simple and easy to learn, improves the accuracy of the diagnostic diagram, saves manpower and financial resources for the later development of the oil field, and lays the foundation for the sustainable development of the oil field.

[0032] Second, the present invention solves the problems of complicated learning process, abstract and difficult to understand, and low learning efficiency of the pumping unit indicator diagram in the prior art through creative learning methods and visual memory tools. Traditional indicator diagram learning methods often rely on rote memorization of abstract concepts and lack of visual understanding of actual mechanical movements, making it difficult for learners to accurately grasp the working principle of the pumping unit and the characteristics of the indicator diagram.

[0033] Through the technical solution of the present invention, especially the introduction of the visual memory method of the red ball rolling on the four sides of the parallelogram, and the systematic memory method of points, lines and surfaces, learners can more intuitively understand the reciprocating motion of the oil pump and the key elements in the indicator diagram. This learning method not only simplifies the complex mechanical principles, making learning more interesting and easy to master, but also significantly improves learning efficiency and memory effect.

[0034] In addition, the present invention also helps learners better identify and troubleshoot abnormalities in actual operations by clarifying the classification and analysis of the factors affecting the dynamometer diagram, thereby improving the accuracy and practicality of the dynamometer diagram analysis. These improvements significantly enhance the application value of the technology, especially in the training of pumping unit operators, and have broad prospects for promotion and application.

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] The following are two industrial application product examples:

[0046] Example 1: Intelligent dynamometer training software

[0047] Develop an intelligent dynamometer diagram training software specifically for the training and education of oilfield technicians. Based on the creative learning method of the pumping unit dynamometer diagram, the software uses animation and simulation technology to visualize the theoretical dynamometer diagram as a parallelogram ABCD, in which the red ball rolls on the four sides to simulate the reciprocating motion of the oil pump. The software includes a variety of learning modules, such as key position memory, stroke path demonstration, fault diagnosis simulation, etc. Trainees can gradually master the operating principles and dynamometer diagram characteristics of the oil pump through interactive exercises and tests. The software can effectively shorten the learning cycle and improve the training effect. It is an important tool for oilfield enterprises to train new technicians.

[0048] Example 2: On-site diagnostic aid

[0049] Design a field dynamometer diagram diagnostic auxiliary device, which is specially used for oilfield technicians to diagnose the status of the pumping unit on site. The device integrates the above-mentioned visual memory method and intelligent algorithm, and can collect the dynamometer diagram data of the pumping unit in real time and visualize it in the form of a parallelogram ABCD. The device screen will display an animation of a rolling red ball to help technicians quickly compare the actual operation trajectory with the standard trajectory. The device can also automatically prompt the fault location and corresponding maintenance suggestions through the built-in fault library and algorithm. This product greatly facilitates on-site operation, reduces diagnostic errors, and improves the maintenance efficiency and reliability of oilfield equipment.

[0050] like Figure 1 As shown, an embodiment of the present invention provides a creative learning method for a pumping unit dynamometer diagram, including a creative diagram of a theoretical dynamometer diagram, in which a red ball rolls back and forth on the four sides of a parallelogram, which actually means that the pumping unit is making reciprocating motion; an innovative memorization method for the theoretical dynamometer diagram is invented, including the meanings represented by points, lines and surfaces, a formula method, a four-point diagonal memorization method, and a four-line side memorization method.

[0051] The one surface, parallelogram ABCD, represents the work done by the oil pump in one stroke; the one ball, using a visual understanding and memory method, the red ball rolls back and forth on the four sides of the parallelogram, which actually refers to the reciprocating motion of the oil pump.

[0052] The four-point diagonal memory method is as follows: point A is the lower dead center, point C is the upper dead center, point B is the loading end point, and point D is the unloading end point.

[0053] The four-line side memory method includes two strokes, an upstroke ABC, and a downstroke CDA.

[0054] Typical dynamometer diagram for a single factor is as follows: Figure 2 shown.

[0055] The influencing factors are: first, human factors; second, ground equipment; third, downhole tools; and fourth, geological factors:

[0056] (1) Main measurement factors of human factors, operation specifications and accuracy;

[0057] (2) The impact of vibration of the pumping unit;

[0058] (3) The impact of vibration caused by downhole tools, sand jams, wax jams, etc. in the oil pump;

[0059] (4) Geological factors, such as sand production from strata, etc., which cause vibrations.

[0060] The present invention relates to a creative learning method of a pumping unit indicator diagram, which aims to help learners better understand and master the working principle of the pumping unit and the characteristics of its indicator diagram through a visual and creative memory method. The method enhances the learning effect by converting complex mechanical movements into images and formulas that are easy to remember.

[0061] 1. Creative drawings and visual memory of theoretical indicator diagrams

[0062] In this method, the theoretical dynamometer diagram is creatively expressed as a parallelogram ABCD. In order to help learners understand the reciprocating motion of the oil pump, this method introduces a visual memory method of a red ball rolling back and forth on the four sides of the parallelogram. Specifically, the red ball symbolizes the motion trajectory of the oil pump in a stroke, and the ball rolling on the four sides of the parallelogram represents the reciprocating motion of the oil pump during actual operation. This visual memory method helps learners connect abstract mechanical motion with specific visual images and deepen their understanding of the theoretical dynamometer diagram.

[0063] 2. The meaning of parallelograms and creative memory methods

[0064] In this learning method, the parallelogram ABCD is used to represent the work done by the oil pump in one stroke. Points A and C represent the bottom dead center and top dead center of the oil pump, respectively. Point B is the loading end point, and point D is the unloading end point. By linking these key points with specific oil pump movement stages, learners can understand the working process of the oil pump more intuitively. In addition, this method also introduces the creative memory method of "points, lines, and surfaces", in which the surface of the parallelogram represents the entire stroke, and the combination of the movement path of the red ball and the points and lines helps learners form a systematic memory framework.

[0065] 3. Four point diagonal memory method

[0066] In order to further strengthen memory, this method proposes a four-point diagonal memory method. Point A is the bottom dead center of the oil pump, point C is the top dead center, point B is the loading end point, and point D is the unloading end point. By arranging these four points in a diagonal form and connecting them with the actual movement stages of the oil pump, learners can more easily remember the key movement positions of the oil pump. This diagonal memory method provides a simple and effective way to simplify the complex mechanical movement process into a few key points that are easy to remember.

[0067] 4. Four lines to the side memory method

[0068] This method also includes a four-line-to-side memory method to further help learners understand the stroke process of the oil pump. The four sides of the parallelogram represent the two strokes of the oil pump, the upper stroke is ABC, and the lower stroke is CDA. By linking these two strokes with the four sides, learners can more intuitively understand the work done by the oil pump and the motion path in each stroke, thereby better grasping the core content of the indicator diagram.

[0069] 5. Identification and classification of influencing factors

[0070] The present invention also involves four main factors that affect the dynamometer diagram: human factors, ground equipment, downhole tools and geological factors. Human factors mainly refer to the operating specifications and accuracy during the measurement process; ground equipment factors include the impact of the vibration of the pumping unit on the dynamometer diagram; downhole tool factors such as sand jams and wax jams in the pumping unit cause vibration interference; geological factors involve the impact of sand production in the formation on the dynamometer diagram. By clarifying these influencing factors, learners can better understand the sources of different anomalies when analyzing the dynamometer diagram and conduct targeted problem troubleshooting.

[0071] 6. Systematic learning and application

[0072] Finally, this method combines the above-mentioned memory techniques, visualization tools, and influencing factor analysis to form a systematic learning path. Through this creative learning method, learners can not only deepen their understanding of the pumping unit indicator diagram, but also apply this knowledge to actual operation and fault analysis. This systematic learning method improves learning efficiency and makes complex mechanical principles and indicator diagram analysis more intuitive and easy to master, which is particularly suitable for application in the training of pumping unit operators.

[0073] Relevant evidence of the technical effects achieved by the embodiments of the present invention.

[0074] First, the harm of wax cards

[0075] like Figure 3 As shown in the figure, wax deposition causes the inner diameter of the oil outlet channel of the wellbore to gradually decrease, increasing the resistance to liquid flow and reducing the production capacity of the oil well. When wax deposition is serious, wax sticking occurs, which eventually causes the oil well to be unable to produce normally and requires frequent well repairs, which not only increases the production management cost of the oil field, but also affects the development effect of the oil field.

[0076] Second, the treatment measures of wax card

[0077] like Figure 4 As shown, including steam wax cleaning, tool wax cleaning, chemical wax cleaning, and self-heat cleaning.

[0078] Third, wax card treatment cases and effect evaluation

[0079] Steaming operation site Figure 5 shown.

[0080] Wu Cai 23-10-1 well of Zhaizihe Oil Production Team, with a production layer length of 2, was steam-waxed on November 26, 2023. The power diagram and production changes before and after wax removal are as follows Figure 6 shown.

[0081] The daily liquid production curve after steam wax cleaning is as follows: Figure 7 shown.

[0082] (IV) Example: Lower tool

[0083] Wucangbao Oil Production Team Qisheng 49-521 Well, production layer is Fuxian Formation, wax stuck on September 11, 2023, during the pump inspection operation, ZYQI super anti-wax viscosity reducer was installed, the performance diagram before and after the operation is as follows Figure 8 shown.

[0084] (V) Example: Wucangbao Oil Production Team Qisheng 49-521 Well, the production layer is Fuxian County. On September 11, 2023, the wax stuck. During the pump inspection operation, the ZYQI super anti-wax viscosity reducer was installed. The production changes before and after the operation are as follows Fig. 9 Show.

[0085] Embodiment 1: Visualization memory method of red ball

[0086] In this embodiment, learners can understand the reciprocating motion of the oil pump in a vivid way by the way the red ball rolls back and forth on the four sides of the parallelogram ABCD. The specific operation steps are as follows:

[0087] 1. Create an image: Draw a parallelogram ABCD in the learning material and mark the four key points A, B, C, and D in it, which correspond to the bottom dead center, load-adding end point, top dead center, and unloading end point of the oil pump respectively.

[0088] 2. Introduce the red ball: Use a red ball (can be a real object or displayed in an image) to simulate the motion trajectory of the oil pump. The red ball rolls along the four sides of the parallelogram, passing through points A, B, C, and D in sequence, simulating the motion process of the oil pump in one stroke.

[0089] 3. Strengthen memory: By repeatedly watching and simulating the movement of the red ball, learners can connect the movement trajectory of the oil pump with the side lines of the parallelogram, and understand the various movement stages in the dynamometer diagram in a visual way.

[0090] 4. Application to dynamometer diagram analysis: In actual operation, learners can recall the scene of the red ball rolling on the four sides of the parallelogram, quickly identify the key points and movement stages in the dynamometer diagram, and assist in analyzing the working status of the oil pump.

[0091] Example 2: Systematic memory method combining points, lines and surfaces

[0092] This embodiment helps learners to systematically grasp the characteristics of the indicator diagram by decomposing the working process of the oil well pump into three parts: "point, line, and surface". The specific operation steps are as follows:

[0093] 1. Remember four points: First, learners remember the four points in the parallelogram ABCD. Point A represents the bottom dead center of the oil pump, point C represents the top dead center, point B is the loading end point, and point D is the unloading end point. Through the diagonal memory method, learners can easily remember the location and meaning of these key points.

[0094] 2. Remember the four lines: Next, learners focus on the four side lines of the parallelogram. The upstroke is represented by the line segment formed by the three points ABC, and the downstroke is represented by the line segment formed by the three points CDA. By memorizing the side lines, learners can intuitively understand the motion path and work done in each stroke.

[0095] 3. Integrate into a plane: Finally, learners integrate the four points and four lines into a complete parallelogram plane, which represents the work done by the oil pump in one stroke. By combining points, lines, and planes, learners can form a complete memory framework and systematically understand the working principle of the oil pump.

[0096] 4. Application to abnormal analysis: When analyzing the actual dynamometer diagram, learners can quickly locate abnormal points in the dynamometer diagram based on the remembered point, line, and surface relationships, and conduct investigations based on influencing factors to improve the accuracy and efficiency of the analysis.
