Description

Technical Field

[0001] The invention relates to the technical field of oil production engineering, and in particular to a pumping control device and method between pumping units. 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-drilled wells is severe, and efficient production faces huge challenges. Intermittent pumping is the main measure to reduce energy consumption and increase production time. Reasonable intermittent pumping can reduce the electricity cost of oil fields while ensuring production, and is an important measure for low-carbon development of oil fields and reducing costs and increasing efficiency.

[0004] There are currently two commonly used effective intermittent pumping methods. The first method is manual intermittent pumping, where field workers manually start and stop the production well several times a day. The second method is automatic intermittent pumping, which is achieved by installing a timer starter and stop device at the well end or by remote control through RTU to achieve automatic start and stop intermittent pumping.

[0005] However, the above solution has the following problems:

[0006] 1. Manual intermittent pumping has high labor costs, insufficient intelligence, and limited application scope; 2. The main problems of automatic intermittent pumping are: (1) The intermittent pumping system is mostly set up based on manual experience, lacking real-time response to collected parameters, lacking effective intermittent pumping system optimization methods, and insufficient intelligence; (2) The pumping unit will generate a large impact current at the moment of restarting. In order to avoid frequent start-up and shutdown caused by excessive current impact damage to the equipment, it is impossible to start and stop frequently to achieve fine intermittent pumping. Too long shutdown time will aggravate sand production and wax deposition in the oil well, which may cause difficulty in restarting the pumping unit; (3) At present, the intermittent pumping control cabinet usually needs to be installed with a frequency converter device or a soft start device, and the control cabinet needs to be transformed into intelligent control. Most of the transformation modes use PLC, single-chip microcomputer and DSP to control the operation of the pumping unit. The current RTU remote transmission control equipment and edge computing intelligent control devices (such as PLC, etc.) are all independently transformed and installed. There is no integrated intelligent control device that can meet the efficient transformation of IoT intelligent intermittent pumping.

[0030] 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. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

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.

[0033] 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.

[0034] At present, the situation of low production and low efficiency of machine-drilled wells is severe, and efficient production faces huge challenges. Intermittent pumping is the main measure to reduce energy consumption and increase production time. Reasonable intermittent pumping can reduce the electricity cost of oil fields while ensuring production, and is an important measure for low-carbon development of oil fields and reducing costs and increasing efficiency.

[0035] There are currently two commonly used effective inter-sampling methods.

[0036] The first method is manual intermittent pumping, where field workers manually start and stop the production well several times a day.

[0037] The second is automatic intermittent pumping, which is achieved by installing a timer start-stop device at the well end or by remote control through RTU.

[0038] However, the above solution has the following problems:

[0039] 1. The labor cost of manual extraction is high, the degree of intelligence is insufficient, and the scope of application is limited.

[0040] 2. The main problems with automatic intermittent pumping are: (1) The intermittent pumping system is mostly set up based on manual experience, lacking real-time response to collected parameters, lacking effective optimization methods for the intermittent pumping system, and insufficient intelligence; (2) The pumping unit will generate a large impact current at the moment of restart. In order to avoid the impact damage to the equipment caused by excessive current caused by frequent start-up and shutdown, it is impossible to start and stop frequently to achieve fine intermittent pumping. If the shutdown time is too long, it will aggravate sand production and wax deposition in the oil well, which may make it difficult to restart the pumping unit.

[0041] Specifically, the above-mentioned automatic intermittent pumping solutions at this stage generally rely on intelligent intermittent pumping control cabinets, which usually require the installation of frequency converters or soft start devices, and the control cabinets need to be transformed into intelligent control. Most of the transformation modes use PLC, single-chip microcomputer and DSP to control the operation of the oil pump.

[0042] At the same time, in order to achieve fine production and intelligent optimization, it is necessary to collect real-time parameters such as power diagrams, liquid levels and electrical parameters through the oilfield Internet of Things, and use edge computing technology to analyze these dynamic parameters to calculate the optimized intermittent pumping scheme. Therefore, intelligent intermittent pumping of oil wells is a system technology that integrates collection, transmission, calculation and control.

[0043] Based on the above analysis of the current pumping control methods, it is found that: currently RTU remote transmission control equipment and edge computing intelligent control devices, such as PLC, are all independently modified and installed. There is no integrated intelligent control device that can meet the efficient transformation of IoT intelligent pumping. The transformation process is complicated, the transformation cost of pumping is high, and the control efficiency is low.

[0044] In order to solve the above problems, the embodiment of the present invention provides an inter-pumping control device for oil pumping units, which is used to improve the efficiency, real-time performance and accuracy of inter-pumping control of oil pumping units and reduce the cost of inter-pumping control.

The intermittent pumping terminal control instructions control the start and stop of the pumping well, the frequency adjustment of the inverter and the working mode adjustment of the pumping well. Compared with the technical solutions for manual intermittent pumping and automatic intermittent pumping in the prior art, the control instructions of the pumping unit can be determined according to the power diagram and electrical parameters of the pumping well, so that the inter-pumping state of the pumping unit can be flexibly controlled based on the pumping unit parameters, thereby realizing the integrated high integration of acquisition, transmission, high-performance computing and intelligent inter-pumping regulation, solving the problems of high cost and low control efficiency of manual inter-pumping and automatic inter-pumping under the prior art, and being able to meet the various requirements of intelligent inter-pumping transformation of oil fields, effectively improving equipment utilization, improving the efficiency of intelligent inter-pumping transformation, reducing the cost of inter-pumping and improving the intelligence level of oil fields.

[0079] In terms of edge computing, it integrates the Raspberry Pi high-performance edge computing chip, supports high-performance edge computing of complex algorithms, and can interact with the cloud to achieve cloud-edge linkage and intelligent extraction;

[0080] In the control sent from the cloud, the cloud service and the hardware level use websocket for long connection interaction. When the user clicks the corresponding button, the intelligent pumping platform will send a control command to the server, and the command will be sent to the WebSocket client of the device through the cloud service. The intelligent terminal converts the digital signal into an electrical signal through the programmable logic control algorithm to control the start and stop of the oil pump.

[0085] In addition, this embodiment provides a multi-interface, highly integrated intelligent terminal for inter-pumping wells, which realizes the integrated high integration of collection, transmission, high-performance computing and intelligent control, and can meet the various requirements of intelligent inter-pumping transformation of various power cabinets in oil fields, effectively improve equipment utilization, enhance the efficiency of intelligent inter-pumping transformation, reduce the cost of inter-pumping and improve the intelligence level of oil fields.

[0086] In this embodiment, according to Figure 2 The double-layer micro-circuit board is set up to process electronic components and weld the embedded circuit board. The embedded circuit board highly integrates the four functions of parameter acquisition, transmission, calculation and control, and is designed with a hard plastic shell suitable for the stacking and connection of the double-layer circuit board. The volume specifications (cm) are as follows: 20×8×6, and the weight is 0.3kg.

[0087] The processed embedded development intelligent module can be easily installed in the control cabinet by magnetic suction (such as Figure 7 The integrated intelligent terminal shown).

[0088] If there is enough space in the modified cabinet, it can also be installed on the guide rail inside the drawer control cabinet.

[0089] There are two main methods for wiring the control terminal and the inverter: one is the direct control mode. If the inverter has a communication interface (such as RS485), use the communication protocol (such as Modbus-RTU) to directly control the inverter; modify the original circuit of the inverter. If the inverter has no communication interface, the original controller circuit needs to be modified, and the relay of the inverter terminal is controlled by digital signals to start and stop.

[0090] In data communication, such as Figure 6 As shown, if the well site has the conditions for IoT communication, cloud communication can be achieved by connecting with RTU. If it does not have the conditions for IoT communication, remote data communication can be achieved through 4G private network and encryption.

[0091] In summary, the system in this embodiment provides a setting scheme for a multi-interface, highly integrated inter-pumping well intelligent terminal, which can realize the integrated high integration of collection, transmission, high-performance computing and intelligent control, and can basically meet the various requirements of intelligent inter-pumping transformation of oil fields, effectively improve equipment utilization, improve the efficiency of intelligent inter-pumping transformation, reduce the cost of inter-pumping and improve the intelligence level of oil fields.
