Description

Technical Field

[0001] The invention relates to the technical field of oil production engineering, and in particular to an intermittent pumping group control device and method for a pumping well. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the invention recited in the claims. No admission is made that the description herein is prior art by inclusion in this section.

[0003] At present, the situation of low production and low efficiency of machine-extracted wells is severe, which makes efficient production face great challenges. Intermittent extraction is the main measure to reduce energy consumption and improve production time. At present, the intermittent extraction system is mainly controlled by manual timing, and a few wells are controlled by remote terminal units (RTU). In order to avoid the impact of excessive current on the equipment caused by frequent start and stop, the intermittent extraction control cabinet usually needs to be installed with a frequency converter or soft start device.

[0004] Reasonable intermittent pumping can reduce the electricity cost of the oil field while ensuring production. The pumping unit will generate a large impact current at the moment of restarting. In order to avoid the impact damage to the equipment caused by excessive current caused by frequent start-up and shutdown, there are currently three commonly used effective intermittent pumping methods.

[0005] The first method uses pumping between ordinary control cabinets. In order to avoid frequent current shocks, the method of long-term shutdown between pumping can only be adopted when ordinary control cabinets are used for pumping. Usually, the pumping unit is started and stopped manually or remotely several times a day, but this will make it difficult to restart the pumping unit. The restart difficulty is particularly severe in cold weather and severe sand production.

[0006] The second method uses a soft start control cabinet. Since the soft starter enables the pumping unit to start softly during the restart process, it can effectively suppress the impact current. Therefore, the device can achieve minute-level precision pumping.

[0007] The third method uses a frequency conversion control cabinet. Since the frequency converter enables flexible control of the pump during restart and can effectively suppress impact current, the device can also achieve minute-level precision pumping.

[0008] Based on the above analysis of the intermittent pumping control method, it is found that the current intermittent pumping control devices are all equipped with a soft starter or inverter in a cabinet to drive a well, which makes the intermittent pumping control cost high, the control efficiency low, and the degree of automation and intelligence insufficient.

[0029] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be appropriately adjusted as needed.

[0032] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0033] At present, the situation of low production and low efficiency of machine-extracted wells is severe, which makes efficient production face great challenges. Intermittent pumping is the main measure to reduce energy consumption and improve production time. At present, the intermittent pumping system is mainly controlled by manual timing, and a few wells are controlled by RTU remote timing. In order to avoid the impact of excessive current on equipment caused by frequent start and stop, the intermittent pumping control cabinet usually needs to be installed with a frequency converter or soft start device.

[0034] Reasonable intermittent pumping can reduce the electricity cost of the oil field while ensuring production. The pumping unit will generate a large impact current at the moment of restarting. In order to avoid the impact damage to the equipment caused by excessive current caused by frequent start-up and shutdown, there are currently three commonly used effective intermittent pumping methods.

[0035] The first method uses pumping between ordinary control cabinets. In order to avoid frequent current shocks, the method of long-term shutdown between pumping can only be adopted when ordinary control cabinets are used for pumping. Usually, the pumping unit is started and stopped manually or remotely several times a day, but this will make it difficult to restart the pumping unit. The restart difficulty is particularly severe in cold weather and severe sand production.

[0036] The second method uses a soft start control cabinet. Since the soft starter enables the pumping unit to start softly during the restart process, it can effectively suppress the impact current. Therefore, the device can achieve minute-level precision pumping.

[0037] The third method uses a frequency conversion control cabinet. Since the frequency converter enables flexible control of the pump during restart and can effectively suppress impact current, the device can also achieve minute-level precision pumping.

[0038] Based on the analysis of the above intermittent pumping control method, it is found that the current intermittent pumping control devices are all equipped with a soft starter in a cabinet to drive a well, which makes the intermittent pumping control cost high, the control efficiency low, and the degree of automation and intelligence insufficient.

[0039] In order to solve the above problems, the embodiment of the present invention provides an intermittent pumping group control device for a pumping well, which is used to improve the utilization rate of the intermittent pumping control equipment, reduce the intermittent pumping control cost of the pumping well, improve the intermittent pumping control efficiency of the pumping well, and improve the intelligent level of oilfield control. Figure 1 , the device may include:

[0040] A soft start controller 01, a power control switch 03 connected to a power source 02, and a single well control switch 05 and a soft start control switch 06 corresponding to each pumping well 04;

[0041] Wherein, for each pumping well: the pumping well, the soft start control switch corresponding to the pumping well, the soft start controller and the power control switch are sequentially connected in series; the series structure formed by the soft start control switch and the soft start controller corresponding to the pumping well is connected in parallel with the single well control switch corresponding to the pumping well;

[0042] The power control switch is used to control the power supply to the soft start controller and the pumping well; the soft start controller is used to start the pumping well in a soft start mode;

[0043] The soft start control switch and the single well control switch are used to open and close according to the pumping well group control instructions during the intermittent pumping cycle to adjust the working status of each pumping well; the above-mentioned pumping well group control instructions include: working status adjustment instructions for different pumping wells during the intermittent pumping cycle.

[0044] In the embodiment of the present invention, a soft start controller, a power control switch connected to a power source, and a single well control switch and a soft start control switch corresponding to each pumping well are provided; wherein, for each pumping well: the pumping well, the soft start control switch corresponding to the pumping well, the soft start controller and the power control switch are sequentially connected in series; the series structure formed by the soft start control switch and the soft start controller corresponding to the pumping well is connected in parallel with the single well control switch corresponding to the pumping well; the power control switch is used to control the power supply of the power source to the soft start controller and the pumping well; the soft start controller is used to start the pumping well in a soft start mode; the soft start control switch and the single well control switch are used to During the cycle, the oil pumping well group control instructions are used to open and close the oil pumping wells to adjust the working status of each oil pumping well; the above-mentioned oil pumping well group control instructions include: working status adjustment instructions for different oil pumping wells during the inter-pumping cycle. Compared with the technical solution of setting a soft starter in the prior art intermediate pumping control device to only drive a single oil pumping well, the soft start control switch and the single well control switch can be opened and closed according to the oil pumping well group control instructions to adjust the working status of multiple oil pumping wells, thereby achieving the purpose of controlling multiple oil pumping wells with one soft starter, effectively improving the utilization rate of inter-pumping control equipment, reducing the inter-pumping control cost of oil pumping wells, improving the inter-pumping control efficiency of oil pumping wells, and improving the intelligent level of oil field control.

[0045] In one embodiment, the soft start controller is specifically used to:

[0046] For each oil pumping well, when the soft start control switch corresponding to the oil pumping well is closed, the oil pumping well is started in a soft start mode.

[0047] In the embodiment, the soft start controller is used to soft-start the pumping motor in the pumping well, which can avoid current shock and achieve the purpose of driving the motor of the pumping well by soft starting with a soft starter, avoiding the problem of a large shock current generated by the pumping unit at the moment of restarting, and can effectively suppress the shock current.

[0048] In one embodiment, the single well control switch is specifically used for:

[0049] For the pumping well after startup, when the single well control switch corresponding to the pumping well is closed, the working state of the pumping well is adjusted to the production state.

[0050] In an embodiment, when the soft start control switch corresponding to the pumping well is closed, a loop can be formed between the pumping well and the power supply via the soft start control switch and the soft start controller corresponding to the pumping well; and when the single well control switch corresponding to the pumping well is closed, the above loop can be short-circuited, so that the power supply current only flows into the single well control switch corresponding to the pumping well, so that the power supply can directly supply power to the pumping well, thereby adjusting the working state of the pumping well to the production state.

[0051] In one embodiment, the single well control switch is specifically used for:

[0052] For each pumping well, when the soft start control switch corresponding to the pumping well is inching closed and turned off, and the single well control switch corresponding to the pumping well is turned off, the working state of the pumping well is adjusted to an intermittent stop pumping state.

[0053] In the embodiment, when the soft start control switch is opened and closed in a jogging manner, the corresponding pumping well can be placed in a jogging intermittent pumping stop state.

[0054] In the above embodiment, by adjusting the working state of the pumping well to an intermittent pumping state, the problem of difficulty in restarting the pumping unit due to long-term pumping interruptions caused by the use of an ordinary control cabinet under the prior art can be avoided. For example, the pumping unit is usually started and stopped manually or remotely several times a day, but this will make it difficult to restart the pumping unit, especially in cold weather and when sand production is severe.

[0055] In one embodiment, it also includes: current transformers, which are respectively installed in the three-phase circuits of the single well and connected to the computer device (computing control module) (such as Figure 3 CT1, CT2, etc.) are used to collect and monitor the voltage, current, power and power factor during the operation of the pumping unit.

[0056] In one embodiment, it also includes: a relay connected to the computing control module, used to drive the single well control switch and the soft starter control switch.

[0057] In one embodiment, the protector is connected to a motor M of a pumping well.

[0058] In the embodiment, the protector is connected to the motor to provide comprehensive protection for the motor. When the motor has overcurrent, undercurrent, phase failure, stall, or short circuit, an alarm is given and the contactor is disconnected to protect the motor.

[0059] In one embodiment, it also includes: an electric meter connected to the calculation control module, which is used to monitor the energy consumption of the oil pump.

[0060] A specific embodiment is given below to illustrate the specific application of the device of the present invention, which is suitable for the industrial field of analyzing and predicting the efficiency of the pumping unit system in oil production using a beam pumping unit.

[0061] At present, based on the analysis of the inter-pumping control method under the existing technology, it is found that the current inter-pumping control devices are all equipped with a cabinet with a soft starter to drive one well. There is no inter-pumping technology that drives multiple wells with one cabinet. The cost of switching to inter-pumping is high, the control efficiency is low, and the degree of automation and intelligence is insufficient. Therefore, there is currently no device that can control multiple wells with one control cabinet. For wells that are close to each other, if the intelligent inter-pumping of multiple wells can be controlled simultaneously by one control cabinet, the cost of switching to inter-pumping can be effectively reduced on-site and the level of automation and intelligence on-site can be improved.

[0062] In order to fill the gap in the current group-controlled intelligent inter-pumping technology for multiple pumping wells, this specific implementation is to set up a control cabinet with the above-mentioned device, which provides a set of intelligent inter-pumping solutions for dual-well collection that can be intelligently controlled with the help of edge computing modules. The control cabinet can adopt a double-sided structure design, with an edge computing intelligent control module, a soft starter, and two sets of dual-node control switches, which can control the intelligent inter-pumping of two wells. The inter-pumping design mode of the device can be extended to multiple wells. The pilot promotion and application was carried out on site, with good application effects, which accelerated the upgrade of digital oil fields and promoted the transformation of oil production workers from blue-collar workers to white-collar workers.

[0063] This specific embodiment can realize the intermittent pumping control of multiple wells, and provides a set of effective multi-well joint intermittent pumping intelligent control solutions, which can improve the utilization rate of equipment, reduce the cost of switching to intermittent pumping, and improve the intelligent control level of the oil field.

[0064] The basic principle of the multi-well staggered intelligent intermittent pumping based on a soft starter provided in this specific embodiment is to control the intermittent pumping time of multiple wells by an intelligent module, and to realize the alternating intermittent pumping of multiple pumping wells by a soft starter.

[0065] like Figure 1As shown, the core circuit in this specific embodiment adopts a parallel design of a soft-start side line and a production well main line, a single-line dual-switch node control, and a multi-line parallel one-control-multi-collection extraction scheme with intelligent response linkage control of parallel line switches.

[0066] Figure 1 , Figure 2 and Figure 3 In the figure, L1, L2, and L3 represent three-phase electricity (i.e., a type of power supply); TA represents the main switch of the control cabinet (i.e., the power control switch); QF1, QF2, and QF3 represent the main line control switches of the three wells (i.e., the single-well control switches of the three pumping wells); KM1, KM2, and KM3 represent the bypass switches (i.e., the soft starter controller) connected to the three wells respectively (i.e., the soft starter control switch).

[0067] As follows, this specific embodiment also provides an implementation scheme of the above control cabinet, which takes two wells as examples:

[0068] The implementation method is explained by taking the "one controls two" double well alternate pumping as an example. For the convenience of explanation, the following assumptions are made:

[0069] 1) The well conditions and fluid supply capacities of the two wells are consistent;

[0070] 2) The optimized pumping-stop ratio of the two wells is 1:1, and the basic intermittent pumping time unit is 15 minutes (an example of an intermittent pumping cycle), that is, the two wells achieve alternating intermittent pumping by pumping for 15 minutes and stopping for 15 minutes.

[0071] The implementation process of this technology is as follows:

[0072] a) When the main switch TA is closed, the single well control switch QF1 is closed, QF2 is disconnected, the soft start control switch KM1 is disconnected, and KM2 is in the disconnected state, then well 1 is in normal production, and well 2 is in an intermittent shutdown state; in addition, the soft start control switch KM1 is disconnected, and KM2 can be opened and closed in a jog manner, so that well 2 is in an intermittent stop state in a jog manner;

[0073] b) If you want to put Well 1 in an intermittent shutdown state and Well 2 to resume production, first close the soft start control switch KM2 to avoid current shock and drive the motor Motor2 of Well 2 to run in a soft start mode. Then close the single well control switch QF2 to replace the soft start circuit, and Well 2 will also start in a soft start mode and enter a normal production state. Secondly, both the single well control switch QF1 and the soft start control switch KM2 are disconnected, and Well 1 stops production. If you want to put Well 1 in an intermittent stop state of inching, you can make the soft start control switch KM1 open and close continuously in an inching mode.

[0074] c) According to the methods in step a) and step b), alternately realize intermittent pumping of well 1 and well 2.

[0075] d) The above intermittent pumping control strategy can be extended to the collective intermittent pumping of multiple wells.

[0076] In this specific embodiment, the inter-well pumping switch control and response logic can also be burned into the control core board of the edge intelligent module to form a multi-well inter-well pumping intelligent control module to achieve real-time optimization of multi-well joint inter-well pumping.

[0077] During the intermittent pumping process, if the pumping unit can be shut down for a longer period of time, that is, the soft starter does not need to be constantly activated to complete the shutdown state during the shutdown process, then the intermittent pumping method of the well group of the collective intermittent pumping is more flexible, and the soft starter only works when a well is restarted. Then, during the intermittent pumping process, the intermittent pumping strategy can be flexibly formulated according to the fluid supply situation of each well in the well group. The soft starter does not need to perform intermittent pumping in sequence, and can randomly perform tasks according to the needs of a single well.

[0078] During intermittent pumping, if the pumping unit cannot be shut down for a long time, that is, the soft starter needs to be constantly activated during the shutdown process to avoid difficulty in restarting the pumping unit caused by long-term shutdown, and the soft starter is still working regularly when a well is in an intermittent period, then it is not recommended to perform cross-intermittent pumping for the wells in the well group, because cross-intermittent pumping will greatly increase the complexity of the control algorithm logic. The method of alternating intermittent pumping for each well in turn can be adopted.

[0079] This specific embodiment also provides a specific structural diagram of the above-mentioned control cabinet, that is, a prototype of a "one control three" intelligent control cabinet. The prototype can use a double-sided structural design, which can make full use of the space inside the cabinet and effectively reduce the volume of the control cabinet.

[0080] The design model of this prototype can be extended to a multi-well joint pumping intelligent control cabinet. Figure 2 It is the internal structure and objects on the front of the control cabinet. The main physical components include soft start controller, main switch, main line control switch, protector, and relay.

[0081] Figure 3 It is the internal structure and physical objects on the back of the control cabinet. The main physical objects include a magnetic edge computing intelligent control module, a soft starter bypass switch, a current sensor (i.e., a current transformer), a relay, a grid input terminal, and a load output terminal.

[0082] In summary, this specific embodiment provides a multi-well intelligent intermittent pumping device that can be intelligently controlled by an edge computing module. Of course, it can be understood that the above detailed process can also have other variations, and the relevant variations should all fall within the protection scope of the present invention.

[0083] In the embodiment of the present invention, a soft start controller, a power control switch connected to a power source, and a single well control switch and a soft start control switch corresponding to each pumping well are provided; wherein, for each pumping well: the pumping well, the soft start control switch corresponding to the pumping well, the soft start controller and the power control switch are sequentially connected in series; the series structure formed by the soft start control switch and the soft start controller corresponding to the pumping well is connected in parallel with the single well control switch corresponding to the pumping well; the power control switch is used to control the power supply of the power source to the soft start controller and the pumping well; the soft start controller is used to start the pumping well in a soft start mode; the soft start control switch and the single well control switch are used to During the cycle, the oil pumping well group control instructions are used to open and close the oil pumping wells to adjust the working status of each oil pumping well; the above-mentioned oil pumping well group control instructions include: working status adjustment instructions for different oil pumping wells during the inter-pumping cycle. Compared with the technical solution of setting a soft starter in the prior art intermediate pumping control device to only drive a single oil pumping well, the soft start control switch and the single well control switch can be opened and closed according to the oil pumping well group control instructions to adjust the working status of multiple oil pumping wells, thereby achieving the purpose of controlling multiple oil pumping wells with one soft starter, effectively improving the utilization rate of inter-pumping control equipment, reducing the inter-pumping control cost of oil pumping wells, improving the inter-pumping control efficiency of oil pumping wells, and improving the intelligent level of oil field control.

[0084] As mentioned above, the embodiment of the present invention can use a soft starter to manage inter-domain pumping of multiple wells by configuring an edge computing intelligent control algorithm module; it can not only meet the basic production requirements, but also realize the soft start of inter-pumping wells to avoid excessive starting current and motor jogging to avoid long-term shutdown, and can also meet the basic needs of energy saving, while also effectively reducing the cost of inter-pumping and improving the intelligence level of the oil field.

[0085] The present invention also provides an intermittent pumping group control device for a pumping well, as described in the following embodiments. Since the principle of the device to solve the problem is similar to the intermittent pumping group control method for a pumping well, the implementation of the device can refer to the implementation of the intermittent pumping group control method for a pumping well, and the repeated parts will not be repeated.

[0086] An embodiment of the present invention provides a method for intermittent pumping group control of a pumping well, which is applied to the intermittent pumping group control device of the pumping well as described above, wherein the intermittent pumping group control device of the pumping well is connected to a plurality of pumping wells. The method is used to improve the utilization rate of the intermittent pumping control equipment, reduce the intermittent pumping control cost of the pumping well, improve the intermittent pumping control efficiency of the pumping well, and improve the intelligent level of oilfield control.
