Description

Technical Field

[0001] The present invention relates to the technical field of enhanced oil and gas production, and particularly to a device for synchronously collecting and drawing the dynamometer card and electric power card of a pumping unit. Background Art

[0002] At present, in portable monitoring instruments for dynamometer cards, displacement measurement uses a wire rope sensor or an acceleration sensor. The stroke range that the wire rope sensor can measure is less than 8 meters, and it cannot test long-stroke (such as vertical) pumping units. Moreover, for working conditions with high stroke frequencies and large loads, breakage and disconnection are likely to occur, causing personal injuries and instrument damage. The displacement value of the acceleration sensor is calculated by measuring the acceleration, and the calculation error is relatively large. Especially at low stroke frequencies, the acceleration at the dead point position is small, resulting in the inability to determine the dead point position, and it is not suitable for energy-saving monitoring. At the same time, during testing, the load sensor is clamped at the suspension clamp. During the long-term field operation of the pumping unit, the clamping surface of the suspension clamp is likely to be uneven or the two sides are not parallel. With the current contact structure of the load sensor, inaccurate load data is likely to be measured during testing.

[0003] Currently, the load and displacement sensors of commonly used dynamometer card testing devices adopt an integrated design. When vibration and the phenomenon of "twisting the braid" occur, it is easy to cause displacement measurement deviation and calculation error. Currently, commonly used energy-saving monitoring devices and systems can no longer meet the testing requirements of the dynamometer cards of some long-stroke, high-stroke-frequency, and large-load pumping units. Energy-saving monitoring of pumping units requires instrument devices with a wider application range, higher accuracy, and stronger reliability.

[0004] The beam pumping unit belongs to an equipment that operates periodically under variable working conditions during the up and down strokes. During the operation of the pumping unit, the working conditions also change greatly in the same time period. In current pumping unit tests, test data such as the suspension point load displacement, current, and power are collected separately by different instruments, and data synchronization cannot be achieved. When the dynamometer card and the electrical parameter data are not synchronized, it affects the accurate calculation of energy-saving monitoring data such as the balance degree. At the same time, only periodic working condition analysis can be carried out, and accurate point working condition analysis cannot be carried out.

[0005] At the same time, the existing production and monitoring instruments and equipment cannot obtain the electric power card of the pumping unit operation at the production site. The electrical parameter test data needs to be read by professional personnel using special software after returning to the base, and the graph is drawn using software such as spreadsheets. The drawn graph cannot be associated with the suspension point displacement and the dynamometer card of the pumping unit. Manual analysis is not intuitive and has poor timeliness, which is not conducive to studying the mutual relationship and combined diagnosis of the dynamometer card and the electric power card. In addition, the working condition analysis and diagnosis overly rely on the quality and experience of the test personnel and technical personnel. It is also a management and technical problem that needs to be solved urgently in the current oilfield mechanical production system that it is impossible to obtain the dynamometer card for some pumping wells and new pumping units (such as ultra-long stroke pumping units), and the experience of manual downhole working condition diagnosis based on the electric power card is insufficient.

[0006] The prior art has at least the following deficiencies:

[0007] 1. For displacement measurement, a wire rope sensor, an acceleration sensor, and an angular displacement sensor are used. The stroke range that the wire rope sensor can measure is less than 8 meters, and it cannot test long-stroke (such as vertical) pumping units. Moreover, in the working conditions of high stroke frequency and large load, it is easy to have problems such as breakage and disconnection, which may cause personal injuries and instrument damage. At the same time, the number of acquisition points of the wire rope sensor is relatively low. In one operating cycle of the pumping unit, the maximum number of acquisition points is 256, and the acquisition accuracy is ±1% F.S., which has a certain impact on the accurate analysis of the working conditions. The displacement values of the acceleration sensor and the angular displacement sensor are calculated by measuring the acceleration, and the calculation error is relatively large, which does not meet the acquisition quality requirements of the national standard for energy-saving monitoring of pumping units and is not suitable for energy-saving monitoring.

[0008] 2. For load measurement, a compressive stress sensor is used. The two compressive stress sensing contacts on the sensor are flat tops. During the test, the sensor is clamped at the suspension clamp. When the pumping unit operates in the wild for a long time, the clamping surface of the suspension clamp is likely to be uneven or the two sides are not parallel, resulting in the compressive stress sensing contact not contacting or having poor contact with the clamping surface, which affects the quality of load measurement.

[0009] 3. When the pumping unit is operating, the pony rod and the suspension clamp always bear the tensile force of the lower alternating load, and it is difficult to avoid the phenomenon of "twisting the pony rod". In the prior art, the load and displacement sensors are integrated, and the sensor is clamped at the suspension clamp. When using laser ranging for displacement measurement, when the pumping unit has the phenomenon of "twisting the pony rod", the laser point will have a large offset, resulting in the displacement value not being measured or having a large error, which affects the quality of displacement measurement.

[0010] 4. The load and displacement sensors are used in combination with the main unit of the oil well comprehensive tester. The device is calibrated and verified in a complete set. If it is misused during the test, it will cause errors in the acquisition of test data. The calculated values such as the integration of the dynamometer card area are completed by the built-in program of the main unit of the oil well comprehensive tester. When an error occurs, it must be sent back to the factory for correction.

[0011] 5. The test data of load displacement and electrical parameters (including active power, current, voltage, power factor, etc.) required for energy-saving monitoring are independently collected, calculated, and output by the oil well comprehensive tester and the electrical energy comprehensive tester respectively, and synchronous control and synchronous data acquisition cannot be carried out; at the production site, it is impossible to obtain the electrical dynamometer card (active power-displacement diagram) of the pumping unit and other electrical parameter-displacement diagrams such as current and power factor.

[0012] 6. The manually drawn electrical dynamometer card cannot be associated with the data and graphics of the indicator diagram. Only the periodic working condition analysis (maximum value, minimum value, average value) of load and electrical parameters can be carried out separately, and the point working condition analysis (a set of load and electrical parameter data corresponding to each displacement point) cannot be carried out, which affects the fine analysis and diagnosis of the working conditions. The analysis is not intuitive and the timeliness is poor. Summary of the Invention

The calibration and verification of the sensors are carried out independently, and the calibration information is retained on the single-chip microcomputer system of each sensor. The sensors do not need to be used in a matching manner, enhancing the compatibility of the equipment; the calculated values such as the integration of the dynamometer diagram area are completed by the supporting program of the portable computer and can be corrected automatically when an error occurs.

The electric power diagram of the pumping unit operation and other electric parameter-displacement diagrams such as current and power factor can be obtained in real time at the production site. The data and graphs such as the dynamometer diagram and electric power diagram can be associated, facilitating the analysis of point working conditions (each displacement point corresponds to a set of load and electric parameter data), enhancing the analysis and diagnosis capabilities, and having good intuitiveness and timeliness.

[0077] The following will make a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings.

[0078] The present invention provides a device for synchronously collecting and drawing the dynamometer card and electric power card of a pumping unit, including: a split-type wireless dynamometer, a radio parameter collector, and a component for synchronously drawing the dynamometer card and electric power card; synchronization refers to the synchronous collection of load, displacement, and electrical parameters, and the formation of synchronous dynamometer cards and electric power cards;

[0079] The prior art can only draw the dynamometer card (load-displacement diagram) on-site and cannot draw the synchronous electric power card (active power-displacement diagram). Firstly, it is impossible to obtain synchronous electrical parameter values; secondly, for the electric power card, a computer, special software installation, and professional personnel are required to read the internal program to obtain data from the integrated electrical energy tester; thirdly, only the EXCEL spreadsheet of the computer can be used for graph drawing. Since the obtained data cannot be associated with the operating conditions of the up and down strokes of the pumping unit, the drawn graph is a curve graph of electrical parameters changing with time (the present invention is a closed curve graph changing with displacement). The present invention can achieve the synchronous collection and drawing of the dynamometer card and electric power card on-site;

[0080] The split-type wireless dynamometer and the radio parameter collector are respectively connected to the component for synchronously drawing the dynamometer card and electric power card;

[0081] The split-type wireless dynamometer includes a wireless load sensor, a wireless laser displacement sensor, and a reflector;

[0082] The wireless load sensor is clamped between the upper splint and the lower splint of the hanger, the wireless laser displacement sensor is placed between the wellhead device or the ground and the reflector, and the reflector is arranged on the hanger; the induction contact of the wireless load sensor adopts a hemispherical top structure;

[0083] There are three methods for displacement acquisition in the prior art: 1. Using a wire rope sensor, the stroke that can be measured is less than 8 meters, and the wire rope is prone to breakage and detachment, posing a safety hazard; 2. Using an acceleration sensor, the displacement is measured indirectly with large errors and cannot meet the accuracy requirements for energy-saving monitoring; 3. Simultaneously using a laser distance sensor and a wire rope sensor, but the displacement sensor is designed as an integral part with the load sensor and is installed on the suspension device of the pumping unit. The laser projects downward from the suspension device. When the pumping unit operates and the suspension device moves up and down with the walking beam of the pumping unit, different degrees of torsion will occur. When the torsion angle is too large, the reflecting point of the laser rangefinder will have a large offset, resulting in no displacement measurement or large measurement errors. All the dynamometers in the prior art adopt an integral structure and cannot all achieve the test of the dynamogram data that meets the quality requirements of the energy-saving monitoring data of the pumping unit with a stroke of more than 8 meters.

[0084] The present invention uses a laser distance sensor to measure displacement data, and the laser distance sensor and the load sensor are independent components. The wireless laser displacement sensor projects upward from the wellhead, and a reflector installed on the suspension device is used to assist in feedback of the light point position. It can test the pumping unit with a stroke of up to 12 meters, and the data accuracy and frequency are higher than those of the prior art.

[0085] The sensing contact of the load sensor in the prior art is a flat-top structure. The sensing contact of the load sensor of the present invention adopts a hemispherical-top structure and an included angle self-correction process. The sensing patches inside the hemispherical-top structure are also arranged in a hemispherical shape. When there is a certain angle between the sensing point and the sensing point in the exact middle of the spherical top, the supporting program automatically corrects the load to the sensing point in the exact middle. In the present invention, the load sensor is installed and clamped between the upper and lower clamping plates of the suspension device. The hemispherical-top structure can ensure that high-quality load data can still be obtained when the clamping surface is uneven, the contact area is small, or there is an included angle when the clamping surfaces are not parallel.

[0086] The wireless load sensor, the wireless laser displacement sensor, and the reflector of the present invention are three independent components. The wireless load sensor is clamped between the upper and lower clamping plates of the suspension device. The laser displacement sensor is placed above the wellhead device and below the reflector. The reflector is arranged at one end of the suspension device to assist the laser displacement sensor in collecting the position of the reflecting light point. The laser displacement sensor can also be placed on the ground.

[0187] Embodiment 3

[0188] According to a specific implementation scheme of the present invention, the synchronous acquisition and drawing process of the indicator diagram and electric work diagram of the present invention will be introduced in detail below.

[0189] (1) Synchronous control and data acquisition

[0190] In the design of the wireless transmission network, adopt a point-to-multipoint method, with the upper computer as the master station and other acquisition modules as slave stations. The master station controls the synchronous time-sharing reading of the data of electrical parameters, wireless indicator instruments, and moving liquid level devices. In the synchronous acquisition, design a complete and sound synchronous control communication message and message parsing mechanism to realize the synchronous control of the acquired data. The upper computer software uses wireless to control two data acquisition single-chip microcomputer systems (i.e., the wireless indicator instrument data acquisition single-chip microcomputer system and the 3169 electrical parameter instrument electrical parameter acquisition single-chip microcomputer system) to perform corresponding actions simultaneously, including operations such as synchronous test initialization, synchronous measurement, and stopping synchronous measurement.

[0191] (2) Full Stroke Judgment and Data Processing

[0192] First, the single-chip microcomputer system of the wireless dynamometer and the single-chip microcomputer system for collecting electrical parameters wait for the upper computer software to send a synchronous test initialization instruction to synchronize the clocks and set the acquisition frequency. When the single-chip microcomputer system of the wireless dynamometer and the single-chip microcomputer system for collecting electrical parameters of the 3169 electrical parameter instrument receive the synchronous measurement instruction simultaneously, they start data acquisition at the same time. The single-chip microcomputer system of the wireless dynamometer and the single-chip microcomputer system for collecting electrical parameters of the 3169 electrical parameter instrument collect according to the acquisition frequency issued by the upper computer, start collecting external data at the same time, and store it at high speed. After storing 800 points, it stops. The upper computer reads 800 points of data from each device, and matches and pairs the data of these two sets of data acquisition single-chip microcomputer systems. Judge the upper and lower dead points of the pumping unit and mark them, extract a complete stroke of data, and save it in a grouped and packaged manner.

[0193] (3) Color-Separated Same-Screen Display and Processing Output

[0194] Based on the grouped and packaged data and marks, with displacement as the abscissa and load, current, active power, and power factor as the ordinates, graph plotting is carried out. The four main curves are displayed synchronously on the same screen, and the upper and lower strokes are displayed in different colors. The main characteristic values such as the maximum and minimum values, stroke, stroke frequency, and the area of the power diagram are automatically searched and calculated by the system and displayed at the bottom of the screen. When the mouse moves above the graph, the parameter values are synchronously displayed. Near the extreme value points, automatic capture can be performed, and the characteristic points can be confirmed by mouse click and marked in the database. For the convenience of intuitive manual analysis, the following different smoothing processing methods can be selected for curve smoothing, and the smoothing processing methods are as follows:

[0195] Smoothing processing is carried out using the linear sliding average method:

[0196] Specifically, the amplitude of a certain point is corrected according to the amplitudes of the sampling points adjacent to it, so as to achieve the purpose of noise reduction of the waveform. The five-point weighted average method is adopted, and the weighting factor {h} = {h -2 , h-1, h0, h1, h2} = (1, 2, 3, 2, 1), and the basic calculation formula is:

[0197]

[0198] In the formula:

[0199] x is the sampling data;

[0200] y is the data after smoothing processing;

[0201] m is the number of data points;

[0202] h is the weighting factor,

[0203] The calculation formula for single-time smoothing is:

[0204] y1 = 1 / 5(3x1 + 2x2 + x3 - x4);

[0205] y2 = 1 / 10(4x1 + 3x2 + 2x3 + x4);

[0206] y i = 1 / 9(x i-2 + 2x i-1 + 3x i + 2x i+1 + x i+2 );

[0207] y m-1 = 1 / 10(x m-3 + 2x m-2 + 3x m-1 + 4x m );

[0208] y m-2 = 1 / 5(-x m-3 + x m-2 + 2x m-1 + 3x m );

[0209] Better noise reduction effects can be obtained by multiple smoothing. The number of smoothing times can be set manually, and the default number of smoothing times is 5 times.

[0210] (4) According to the energy-saving monitoring calculation and evaluation program in the software system, automatically search for and calculate each characteristic value, compare it with the energy-saving limit and evaluation value automatically calculated by the supporting software system, output the calculation results and the compliance evaluation conclusion, and generate a monitoring result report in real time.

[0211] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
