Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil production engineering, and particularly relates to an interval pumping group control device and method for a pumping unit well. BACKGROUND

[0002] This section is intended to provide background information to facilitate a better understanding of embodiments of the present application described in the claims. The description herein does not constitute admission of prior art.

[0003] At present, the situation of low production and low efficiency of machine pumping wells is serious, which makes the benefit production face great challenges. Interval pumping is a main measure to reduce energy consumption and improve production efficiency. At present, the interval pumping system is mainly controlled by artificial timing, and a few wells are controlled by remote terminal unit (RTU) timing. In order to avoid the impact of excessive current on the equipment caused by frequent start-stop of the machine, a frequency converter device or a soft start device is usually installed in the interval pumping control cabinet.

[0004] Reasonable interval pumping can reduce the power consumption of oilfields on the premise of ensuring production. The pumping unit will produce a large impact current in the moment of restarting. In order to avoid the impact of excessive current on the equipment caused by frequent start-stop of the machine, the following three effective interval pumping methods are commonly used.

[0005] The first method is to adopt ordinary control cabinet interval pumping. In order to avoid frequent current impact, the method of long-time shutdown interval pumping can only be used when the ordinary control cabinet is adopted. The machine is started and stopped manually or remotely several times a day, but this will cause difficulty in restarting the pumping unit, especially in cold weather and severe sand production.

[0006] The second method is to adopt a soft start control cabinet. Since the soft starter enables the pumping unit to realize soft start during the restarting process, it can effectively suppress the impact current, so that the device can realize minute-level fine system interval pumping.

[0007] The third method is to adopt a variable frequency control cabinet. Since the frequency converter enables the pumping unit to realize flexible control during the restarting process, it can also effectively suppress the impact current, so that the device can also realize minute-level fine system interval pumping.

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

[0033] At present, the situation of low production and low efficiency of machine pumping wells is serious, which makes the benefit production face great challenges. The interval extraction is the main measure to reduce energy consumption and improve production efficiency. At present, the interval extraction system is mainly controlled by artificial timing, and a few wells are controlled by RTU remote timing control. In order to avoid the impact of excessive current on the equipment caused by frequent start-stop machine, the interval extraction control cabinet usually needs to install frequency converter device or soft start device.

[0034] Reasonable interval extraction can reduce the power consumption of oil field under the premise of ensuring production. The pumping unit will produce a large impact current in the moment of restarting. In order to avoid the impact of excessive current on the equipment caused by frequent start-stop machine, the effective interval extraction methods commonly used at present are as follows.

[0035] The first method adopts ordinary control cabinet interval extraction. In order to avoid frequent current impact, the long-time shutdown interval extraction method can only be used when the ordinary control cabinet interval extraction is adopted. The pumping unit is usually started and stopped manually or remotely several times a day, but this will cause the difficulty of restarting the pumping unit, which is especially true in cold weather and severe sand production conditions.

[0036] The second method adopts soft start control cabinet. Since the soft starter realizes soft start of the pumping unit during restarting, it can effectively suppress the impact current, so that the device can realize minute-level fine system interval extraction.

[0037] The third method adopts variable frequency control cabinet. Since the frequency converter realizes flexible control of the pumping unit during restarting, it can also effectively suppress the impact current, so that the device can also realize minute-level fine system interval extraction.

[0038] Based on the analysis of the above interval extraction control methods, it is found that the current interval extraction control device is a cabinet with a soft starter to drive a well, which makes the interval extraction control cost high, the control efficiency low, and the automation and intelligence degree insufficient.

[0039] In order to solve the above problems, the embodiment of the present application provides an interval extraction group control device of pumping unit well, which is used to improve the utilization rate of interval extraction control equipment, reduce the interval extraction control cost of pumping unit well, improve the interval extraction control efficiency of pumping unit well, and improve the intelligent level of oil field control, see Figure 1 The device can include:

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

[0041] The pumping unit, the soft start control switch corresponding to the pumping unit, the soft start controller and the power supply control switch are connected in series in sequence.

[0042] The power supply control switch is used for controlling power supply of the soft start controller and the pumping unit.

[0043] The soft start control switch and the single-well control switch are used for opening and closing according to the pumping unit group control instruction to adjust the working state of each pumping unit in the interval pumping period.

[0044] In the embodiment, the soft start controller, the power supply control switch connected with the power supply, and the single-well control switch and the soft start control switch corresponding to each pumping unit are arranged. For each pumping unit, the pumping unit, the soft start control switch corresponding to the pumping unit, the soft start controller and the power supply control switch are connected in series in sequence. The series structure formed by the soft start control switch and the soft start controller corresponding to the pumping unit is connected in parallel with the single-well control switch corresponding to the pumping unit. The power supply control switch is used for controlling power supply of the soft start controller and the pumping unit. The soft start controller is used for starting the pumping unit in a soft start mode. The soft start control switch and the single-well control switch are used for opening and closing according to the pumping unit group control instruction to adjust the working state of each pumping unit in the interval pumping period. The pumping unit group control instruction includes the working state adjustment instruction of different pumping units in the interval pumping period. Compared with the technical solution that one soft starter in the prior art interval pumping control device can only drive a single pumping unit, the soft start control switch and the single-well control switch can be opened and closed according to the pumping unit group control instruction to adjust the working state of multiple pumping units, the purpose of controlling multiple pumping units by one soft starter is achieved, the utilization rate of the interval pumping control equipment can be effectively improved, the interval pumping control cost of the pumping unit is reduced, the interval pumping control efficiency of the pumping unit is improved, and the intelligent level of oil field control is improved.

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

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

[0047] In the embodiment, the soft start controller is used for soft starting the pumping motor in the pumping well, so as to avoid current impact, achieve the purpose of driving the motor of the pumping well to run in the soft start mode, and avoid the problem that the pumping well will generate a large impact current in the moment of restarting, so as to effectively suppress the impact current.

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

[0049] For the pumping well after starting, 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 the 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 from the single-well control switch, so that the power supply can directly supply power to the pumping well, and thus the working state of the pumping well is adjusted 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 closed and opened in a jog mode, and the single-well control switch corresponding to the pumping well is closed, the working state of the pumping well is adjusted to the intermittent stop pumping state.

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

[0054] In the above embodiment, by adjusting the working state of the pumping well to the intermittent stop pumping state, the problem that the pumping well can only be stopped for a long time in the prior art to cause difficulty in restarting the pumping well can be avoided, for example, the pumping well is usually started and stopped manually or remotely several times a day, but this will cause difficulty in restarting the pumping well, and the difficulty in restarting the pumping well is particularly serious in cold weather and severe sand production.

[0055] In one embodiment, it further includes: a current transformer installed in the three-phase circuit of the single well and connected with the computer device (the calculation control module) (such as CT1, CT2, etc. in Figure 3 , for collecting and monitoring the voltage, current, power and power factor during the operation of the pumping well.

[0056] In one embodiment, it further includes: a relay connected to the calculation control module, for driving the single-well control switch and the soft start control switch.

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

[0058] In one embodiment, the protector is connected to the motor, and is used for overall protection of the motor, and alarms and disconnects the contactor to protect the motor when overcurrent, undercurrent, open phase, locked rotor, and short circuit occur in the motor.

[0059] In one embodiment, the meter is further connected to the calculation control module, and is used for monitoring the energy consumption of the pumping unit.

[0060] A specific embodiment is given below to illustrate the specific application of the device of the present application, which is suitable for the industrial field of efficiency analysis and prediction of pumping unit systems in beam pumping units.

[0061] At the present stage, based on the analysis of the existing technology of the intermittent pumping control method, it is found that the current intermittent pumping control device is a cabinet with a soft starter driving one well, and there is no intermittent pumping technology with one cabinet driving multiple wells. The conversion of intermittent pumping has high cost, low control efficiency, and insufficient automation and intelligence. Therefore, there is currently no device that can control multiple wells through one control cabinet. For wells with close well positions, if intelligent intermittent pumping of multiple wells can be controlled through one control cabinet, the cost of on-site conversion of intermittent pumping can be effectively reduced, and the automation and intelligence level of the site can be improved. Through

[0062] In order to fill the gap of the current multi-pumping well group control intelligent intermittent pumping technology, the present embodiment provides a control cabinet with the above device, which provides a set of double-well set intelligent intermittent pumping scheme that can be intelligently controlled with the help of an edge computing module. The control cabinet can adopt a double-sided structure design, has an edge computing intelligent control module, a soft starter, and two sets of double-node control switches, and can control the intelligent intermittent pumping of two wells. The intermittent pumping design mode of the device can be extended to multiple wells. The pilot application is carried out on site, and the application effect is good, which accelerates the upgrading of digital oilfields and promotes the transformation of oil production workers from blue-collar to white-collar.

[0063] The present embodiment can realize the intermittent pumping control of multiple well sets, and provides an effective intelligent control scheme for multiple well joint intermittent pumping, which can improve the utilization rate of equipment, reduce the cost of conversion of intermittent pumping, and improve the intelligent control level of oilfields.

[0064] The multi-well error domain intelligent intermittent pumping based on the soft starter provided by the present embodiment has the basic principle of controlling the intermittent pumping time of multiple wells through an intelligent module, and realizing the alternate intermittent pumping of multiple pumping unit wells by a soft starter.

[0065] As Figure 1As shown, the core circuit in the embodiment adopts a parallel design of the soft start bypass circuit and the main circuit of the production well, single-circuit double-switch node control, and parallel circuit switch intelligent response linkage control of the multi-circuit parallel one-control multi-set interval pumping scheme.

[0066] Figure 1 、 Figure 2 and Figure 3 In the above formula, L1, L2, L3 represent three-phase power (i.e., one kind of power supply); TA represents the control cabinet total switch (i.e., the power supply control switch); QF1, QF2, QF3 represent the main circuit control switches of the three wells (i.e., the single-well control switches of the three oil pumping wells); KM1, KM2, KM3 represent the bypass switches (i.e., the soft start control switches) connected with the soft starters (i.e., the soft start controllers) of the three wells, respectively.

[0067] As follows, the embodiment also gives an implementation scheme of the above control cabinet, which takes two wells as an example:

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

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

[0070] 2) The optimized pumping and stopping ratio of the two wells is 1:1, and the basic interval pumping time unit is 15 minutes (i.e., an instance of the interval pumping period), that is, the two wells realize alternate interval pumping by the interval pumping system of pumping for 15 minutes and stopping for 15 minutes, respectively.

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

[0072] a) The total switch TA is closed, the single-well control switch QF1 is closed, the single-well control switch QF2 is opened, the soft start control switch KM1 is opened, and the soft start control switch KM2 is in the open state, so that well 1 is in normal production and well 2 is in intermittent stop state. In addition, the soft start control switch KM1 is opened, and the soft start control switch KM2 can be opened and closed in a point-by-point manner, so that well 2 is in a point-by-point intermittent stop pumping state;

[0073] b) If well 1 is to be in an intermittent stop state and well 2 resumes production, the soft start control switch KM2 is first closed to avoid current impact and drive the motor Motor2 of well 2 to run in a soft start manner by the soft starter, and then the single-well control switch QF2 is closed to replace the soft start circuit, so that well 2 also starts in a soft start manner and enters a normal production state. Secondly, the single-well control switch QF1 and the soft start control switch KM2 are both opened, and well 1 stops production. If well 1 is to be in a point-by-point intermittent stop pumping state, the soft start control switch KM1 can be opened and closed in a point-by-point manner.

[0074] c) Alternately implement the intermittent pumping of well 1 and well 2 according to the method in step a) and step b).

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

[0076] In the present embodiment, the intermittent 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 intermittent pumping intelligent control module, realizing real-time optimization of multi-well joint intermittent pumping.

[0077] If the pumping unit can be stopped for a long time during the intermittent pumping, i.e., it does not need to be constantly excited by the soft starter to complete the stop state, the set of intermittent pumping wells is more flexible, and the soft starter only works when a well is restarted. Therefore, the soft starter can execute tasks randomly according to the demand of each well during the intermittent pumping without the need for sequential and alternating intermittent pumping.

[0078] If the pumping unit cannot be stopped for a long time during the intermittent pumping, i.e., it needs to be constantly excited by the soft starter to avoid restarting difficulties caused by long-term stoppage, the soft starter is still working at a constant time without stopping during the intermittent period of a well. Therefore, it is not recommended to cross-intermittently pump each well in the well group, because cross-intermittent pumping will greatly increase the complexity of the control algorithm logic, and the method of sequentially and alternately intermitting each well can be used.

[0079] The present embodiment also provides a specific structure diagram of the above control cabinet, i.e., a prototype of a "one control three" intelligent control cabinet. The prototype can use a double-sided structure design, which can fully utilize the space inside the cabinet and effectively reduce the size of the control cabinet.

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

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

[0082] In summary, the present embodiment provides a set of multi-well set intelligent intermittent pumping devices that can be intelligently controlled with the aid of edge computing modules. Of course, it can be understood that the above detailed process can have other variations, and the relevant variations should fall within the protection scope of the present application.

[0083] In the embodiment of the present application, a soft start controller, a power supply control switch connected with the power supply, and a single-well control switch and a soft start control switch corresponding to each pumping unit well are arranged; wherein, for each pumping unit well: the pumping unit well, the soft start control switch corresponding to the pumping unit well, the soft start controller and the power supply control switch are connected in series; the series structure formed by the soft start control switch corresponding to the pumping unit well and the soft start controller is connected in parallel with the single-well control switch corresponding to the pumping unit well; the power supply control switch is used to control the power supply to supply power to the soft start controller and the pumping unit well; the soft start controller is used to start the pumping unit well in a soft start mode; the soft start control switch and the single-well control switch are used to open and close according to the pumping unit group control instruction in the intermittent pumping period, to adjust the working state of each pumping unit well; compared with the prior art technical solution in which one soft starter is arranged to drive only one pumping unit well, the opening and closing of the soft start control switch and the single-well control switch can be controlled according to the pumping unit group control instruction to adjust the working state of multiple pumping unit wells, so that the purpose of controlling multiple pumping unit wells with one soft starter is achieved, the utilization rate of the intermittent control equipment can be effectively improved, the intermittent control cost of the pumping unit well is reduced, the intermittent control efficiency of the pumping unit well is improved, and the intelligent level of oil field control is improved.

[0084] As described above, in the embodiment of the present application, the edge computing intelligent control algorithm module is configured, so that one soft starter can be used to manage multiple wells in the error domain; the basic demand for production can be met, the soft start of the intermittent well can be realized to avoid too large starting current and the motor point-to-point operation to avoid long downtime, the basic demand for energy saving can be met, the intermittent pumping cost can be effectively reduced, and the intelligent level of the oil field can be improved.

[0085] In the embodiment of the present application, an intermittent group control device for pumping unit wells is also provided, which is described in the following embodiment. Since the principle of solving the problem of the device is similar to the intermittent group control method for pumping unit wells, the implementation of the device can be referred to the implementation of the intermittent group control method for pumping unit wells, and the repeated parts will not be described again.

[0086] The intermittent group control method for pumping unit wells provided by the embodiment of the present application is applied to the intermittent group control device for pumping unit wells as described above, the intermittent group control device for pumping unit wells is connected with multiple pumping unit wells, and the method is used to improve the utilization rate of the intermittent control equipment, reduce the intermittent control cost of the pumping unit well, improve the intermittent control efficiency of the pumping unit well, and improve the intelligent level of oil field control, as shown in the following formula: Figure 4 The method comprises the following steps:
