DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0042] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] As introduced in the background technology, the main work of the fracturing pump is to transport the fracturing fluid to the bottom of the well under very high pressure, causing the rocks at the bottom of the well to crack, creating a larger transportation channel for oil and gas under the rock formation, increasing the transportation rate, and thus increasing the oil production rate. Among them, in order to achieve the purpose of cracking the rocks at the bottom of the well, it is mainly necessary to rely on the power end of the fracturing pump to convert the liquid energy of the fracturing fluid into the liquid energy of the fracturing fluid through the hydraulic end, so that the fracturing fluid is injected into the formation at a certain speed. This process causes greater wear on the hydraulic end, and the service life of the hydraulic end is limited. The hydraulic end of the fracturing pump needs to be replaced after a period of use to improve work efficiency and the safety of the construction environment.

[0044] At present, the cumulative working time of the hydraulic end of the fracturing pump and the number of times the hydraulic end of the fracturing pump has been replaced are still recorded and calculated manually. However, manual calculation has the disadvantages of omissions and inaccurate recording time. How to accurately calculate the cumulative working time of the hydraulic end and the number of times the hydraulic end has been replaced is a problem worth studying.

[0045] The embodiment of the present application provides a fracturing pump detection system for detecting a fracturing pump, wherein the fracturing pump includes a power end and a hydraulic end detachably connected to the power end. The system includes a control device, a detection unit, and an identification unit. The detection unit obtains the working information of the hydraulic end stored in the identification unit, and the cumulative working time of the hydraulic end and the number of times the hydraulic end of the fracturing pump has been replaced are counted based on the working information. In this way, the accuracy of calculating the cumulative working time of the hydraulic end and the number of times the hydraulic end has been replaced is improved. The above system is described in detail below.

[0046] See also Figure 1 An embodiment of the present application provides a fracturing pump detection system 100 for detecting a fracturing pump, wherein the fracturing pump includes a power end 310 and a hydraulic end 320 detachably connected to the power end 310 , and the fracturing pump detection system 100 includes a control device 30 , a detection unit 10 and an identification unit 20 .

[0047] The detection unit 10 is installed at the power end 310 of the fracturing pump, and the identification unit 20 is installed at the hydraulic end 320 of the fracturing pump.

[0048] The identification unit 20 is used to store the working information of the hydraulic end 320 .

[0049] The detection unit 10 is used to obtain the working information of the hydraulic end 320 stored in the identification unit 20 in real time, and send the working information to the control device 30 .

[0050] The control device 30 is used to count the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced according to the working information.

[0051] The detection unit 10 may be a RFID (Radio Frequency Identification) reader / writer, and the identification unit 20 may be a passive RFID tag.

[0052] RFID readers can perform non-contact two-way data communication with passive RFID tags. RFID readers use wireless radio frequency to read and write passive RFID tags, thereby achieving the purpose of target identification and data exchange.

[0053] Furthermore, the passive RFID tag receives microwave signals transmitted by the RFID reader and obtains energy through the electromagnetic induction coil to temporarily power itself, thereby completing an information exchange. Because the power supply system is omitted, the volume of the passive RFID tag can reach the centimeter level or even smaller, and it has a simple structure, low cost, low failure rate, and long service life.

[0054] The control device 30 may be an integrated circuit chip with signal processing capability. The control device 30 may be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), and the like.

[0055] It can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The general processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0056] Since the hydraulic end 320 of the fracturing pump needs to be replaced as needed, an identification unit 20 is provided on each hydraulic end 320 , and the working information stored in each identification unit 20 includes the unique identification information of the hydraulic end 320 where the identification unit 20 is located.

[0057] The identification unit 20 can be directly embedded in the hydraulic end 320 when the hydraulic end 320 is manufactured, or the identification unit 20 can be placed on the hydraulic end 320 by adhesive or other connecting parts to prevent the identification unit 20 from falling off.

[0058] It is understandable that each time the hydraulic end 320 is replaced, the working information stored in the identification unit 20 will also change, and the working information recognized by the detection unit 10 will also change accordingly. The cumulative working time of each hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced can be counted based on the working information. In this way, the accuracy of calculating the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced is improved.

[0059] For further information, please refer to Figure 2 The fracturing pump detection system 100 in the embodiment of the present application further includes a data transmission device 40 , and the detection unit 10 and the control device 30 are respectively connected to the data transmission device 40 .

[0060] The detection unit 10 is used to send the working information to the control device 30 through the data transmission device 40. The data transmission device 40 may include an RS485 communication module, a ZIGBEE module, a LORA module, a GPRS module or a 3G / 4G embedded wireless data transmission module. The working information is transmitted through the data transmission device 40 to improve the transmission security and stability of the working information.

[0061] It is understandable that when the cumulative working time of the hydraulic end 320 is close to the service life of the hydraulic end 320, a new hydraulic end 320 can be replaced to avoid potential safety hazards or reduced working speed due to damage to the hydraulic end 320. Therefore, the fracturing pump detection system 100 in the embodiment of the present application further includes an alarm device 70 connected to the control device 30, and the alarm device 70 is used to send an alarm signal under the control of the control device 30 to remind the user to replace the new hydraulic end 320 in time.

[0062] The alarm device 70 may be an LED light, a buzzer, a voice prompt module or any combination thereof. When the cumulative working time of the hydraulic end 320 is counted to exceed a preset threshold, the alarm device 70 is controlled to send an alarm signal to remind the staff to replace or maintain the hydraulic end 320. This reduces the potential safety hazards caused by damage to the hydraulic end 320 and improves work efficiency.

[0063] Furthermore, the fracturing pump detection system 100 further includes a pressure sensor 50, which is installed at the hydraulic end 320 and is used to detect the pressure value of the hydraulic end 320. The control device 30 is also used to obtain the pressure value and determine whether the hydraulic end 320 starts working according to the pressure value. In this way, the cumulative working time of the hydraulic end 320 can be calculated according to the time from when the hydraulic end 320 starts working to when it ends working.

[0064] Furthermore, the fracturing pump detection system 100 further includes an output rotation speed detection device 60 , which is connected to the power end 310 and is used to detect the output rotation speed of the power end 310 .

[0065] The control device 30 is also used to obtain the output speed, and determine whether the hydraulic end 320 connected to the power end 310 starts working according to the output speed. In this way, the cumulative working time of the hydraulic end 320 can be calculated according to the time from when the hydraulic end starts working to when it ends working.

[0066] It can be understood that the fracturing pump detection system in the embodiment of the present application can include only the above-mentioned pressure sensor 50 or the output speed detection device 60, or can also include the above-mentioned pressure sensor 50 and the output speed detection device 60 at the same time. The pressure sensor 50 and the output speed detection device 60 are used to jointly determine whether the hydraulic end 320 starts working, thereby improving the accuracy of calculating the cumulative working time of the hydraulic end 320.

[0067] Please refer to Figure 3 The embodiment of the present application further provides a fracturing pump detection method, which is applied to the control device 30 in the above-mentioned fracturing pump detection system 100, and the method includes:

[0068] Step S1 , based on the detection unit 10 , the working information of the hydraulic end 320 stored by the identification unit 20 is obtained in real time.

[0069] Step S2, counting the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced according to the working information obtained in real time.

[0070] It is understandable that since the hydraulic end 320 of the fracturing pump needs to be replaced as needed, an identification unit 20 is provided on each hydraulic end 320, and the working information stored in each identification unit 20 includes the unique identification information of the hydraulic end 320 where the identification unit 20 is located.

[0071] Each time the hydraulic end 320 is replaced, the working information stored in the identification unit 20 will also change, and the working information recognized by the detection unit 10 will also change accordingly. Therefore, the cumulative working time of each hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced can be counted based on the working information. In this way, the accuracy of calculating the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced is improved.

[0072] For the convenience and brevity of description, the types of specific components included in the method described above can refer to the corresponding description in the aforementioned system, and will not be repeated here.

[0073] As an optional implementation, the number of times the hydraulic end 320 of the fracturing pump has been replaced is obtained by the following steps:

[0074] It is determined whether the unique identification information included in the real-time acquired working information is consistent with the unique identification information included in the last acquired working information. If not, the number of times the hydraulic end 320 of the fracturing pump has been replaced is increased by one.

[0075] For example, the unique identification information included in the working information obtained in real time is 123456, and the unique identification information included in the working information obtained last time is 654321. It can be seen from the comparison that the unique identification information included in the working information obtained in real time is inconsistent with the unique identification information included in the working information obtained last time, indicating that the hydraulic end 320 of the fracturing pump has been replaced. At this time, the number of replacement times of the hydraulic end 320 of the fracturing pump is increased by one.

[0076] As another optional implementation, the storage unit included in the control device 30 stores the historical replacement times of the hydraulic end 320 of the fracturing pump. The replacement times of the hydraulic end 320 of the fracturing pump can also be obtained by the following steps:

[0077] It is determined whether the unique identification information included in the real-time working information is consistent with the unique identification information included in the last working information obtained. If not, the historical replacement times of the hydraulic end 320 of the fracturing pump are obtained, the historical replacement times are increased by one, and saved.

[0078] For example, the unique identification information included in the real-time working information is 123456, and the unique identification information included in the last working information obtained is 654321. It can be seen from the comparison that the unique identification information included in the real-time working information is inconsistent with the unique identification information included in the last working information obtained, indicating that the fracturing pump has replaced a new hydraulic end 320. Next, the historical replacement number of the hydraulic end 320 of the fracturing pump is obtained. Assuming that the historical replacement number obtained is 11 times, the historical replacement number is increased by one, and a new historical replacement number of 12 times is obtained and saved.

[0079] It is understandable that the above-mentioned saved historical replacement times may also be 0, that is, the hydraulic end 320 of the fracturing pump has never been replaced.

[0080] As an optional implementation, in the embodiment of the present application, the working information also includes the accumulated working time of the hydraulic end 320. The accumulated working time of the hydraulic end 320 can be obtained by the following steps:

[0081] The current working time of the hydraulic end 320 from the time when the hydraulic end 320 starts working to the time when the hydraulic end 320 ends working is calculated, the sum of the current working time and the accumulated working time is used as the new accumulated working time of the hydraulic end 320, and the new accumulated working time is written into the identification unit 20.

[0082] For example, the hydraulic end 320 starts working at 12:10 on October 7, 2019, and ends working at 12:10 on October 8, 2019. It is calculated that the current working time is 24 hours. Assuming that the working information of the hydraulic end 320 includes a cumulative working time of 320 hours, it is calculated that the new cumulative working time of the hydraulic end 320 is 320+24=344 hours.

[0083] It is understandable that the accumulated working time of the hydraulic end 320 included in the above working information may be 0, that is, the hydraulic end 320 is a new hydraulic end 320 .

[0084] For further information, please refer to Figure 4 As an optional implementation, the fracturing pump detection system 100 further includes a pressure sensor 50, and the pressure sensor 50 is installed at the hydraulic end 320. The fracturing pump detection method further includes a step of determining whether the hydraulic end 320 starts to work, and the step includes:

[0085] Step S211 , obtaining the pressure value of the hydraulic end 320 based on the pressure sensor 50 .

[0086] Step S212, determining whether the pressure value is greater than a first preset threshold.

[0087] Step S213: if it is greater than, it is determined that the hydraulic end 320 starts to work.

[0088] Step S214: Otherwise, it is determined that the hydraulic end 320 has not started to work.

[0089] The first preset threshold value may be 0. In the embodiment of the present application, the pressure sensor 50 detects the pressure value of the hydraulic end 320 to determine whether the pressure value is greater than 0. When the pressure value of the hydraulic end 320 is greater than 0, it can be determined that the hydraulic end 320 starts working. Otherwise, the hydraulic end 320 does not start working. In this way, the accuracy of calculating the accumulated working time of the hydraulic end 320 is improved by combining the pressure value to determine whether the hydraulic end 320 starts working.

[0090] As another optional implementation, please refer to Figure 5 The fracturing pump detection system 100 further includes an output speed detection device 60, and the output speed detection device 60 is connected to the power end 310. The fracturing pump detection method further includes a step of determining whether the hydraulic end 320 starts working, and the step includes:

[0091] Step S221 : acquiring the output speed of the power end 310 based on the output speed detection device 60 .

[0092] Step S222, determining whether the output speed is greater than a second preset threshold.

[0093] Step S223: If it is greater than, it is determined that the hydraulic end 320 connected to the power end 310 starts to work.

[0094] Step S224: Otherwise, it is determined that the hydraulic end 320 connected to the power end 310 has not started to work.

[0095] The second preset threshold value may be 0, and the output speed detection device 60 may be a gearbox. In the embodiment of the present application, the output speed detection device 60 detects the output speed of the power end 310. When the output speed is greater than 0, it can be determined that the hydraulic end 320 connected to the power end 310 has started to work, otherwise the hydraulic end 320 has not started to work. In this way, the accuracy of calculating the accumulated working time of the hydraulic end 320 is improved by combining the output speed to determine whether the hydraulic end 320 has started to work.

[0096] As another optional embodiment, the fracturing pump detection system 100 further includes an output speed detection device 60, which is connected to the power end 310. The fracturing pump detection system 100 further includes a pressure sensor 50, which is installed on the hydraulic end 320. Figure 6, judging whether the hydraulic end 320 starts to work can also be achieved through steps S231 to S236.

[0097] Step S231 : acquiring the pressure value of the hydraulic end 320 based on the pressure sensor 50 .

[0098] Step S232, determining whether the pressure value is greater than a first preset threshold.

[0099] Step S233 : if it is greater than , the output speed of the power end 310 is obtained based on the output speed detection device 60 .

[0100] Step S234, determining whether the output speed is greater than a second preset threshold.

[0101] Step S235: if it is greater than, it is determined that the hydraulic end 320 connected to the power end 310 starts to work.

[0102] Step S236: Otherwise, it is determined that the hydraulic end 320 has not started to work.

[0103] Similar to the above two embodiments, the first preset threshold value may be 0, and the second preset threshold value may also be 0. When the pressure sensor 50 detects that the pressure value of the hydraulic end 320 is greater than 0, the output speed calculated by the output speed detection device 60 is further obtained. When the output speed is greater than 0, it can be determined that the hydraulic end 320 has started to work, otherwise, it can be determined that the hydraulic end 320 has not started to work. In this way, whether the hydraulic end 320 has started to work is determined by the pressure value and the output speed, which further improves the accuracy of calculating the accumulated working time of the hydraulic end 320.

[0104] It can be understood that the order of judging the pressure value and the first preset threshold and judging the output speed and the second preset threshold is not limited here. That is to say, the pressure value and the first preset threshold can be judged first, and then the output speed and the second preset threshold can be judged, or the output speed and the second preset threshold can be judged first, and then the pressure value and the first preset threshold can be judged.

[0105] The fracturing pump detection method provided in the embodiment of the present application is based on the detection unit 10, and obtains the working information of the hydraulic end 320 stored in the identification unit 20 in real time, and counts the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 of the fracturing pump has been replaced according to the working information. In this way, the accuracy of calculating the cumulative working time of the hydraulic end 320 and the number of times the hydraulic end 320 has been replaced is improved.

[0106] Please refer to Figure 7The embodiment of the present application further provides a fracturing device 1, including a fracturing pump 300 and the above-mentioned fracturing pump detection system 100, wherein the fracturing pump detection system 100 is used to detect the fracturing pump 300.

[0107] Furthermore, the fracturing equipment 1 further includes a driving device 200, which is connected to the fracturing pump 300 and is used to drive the fracturing pump 300 to work. The driving device 200 may include a diesel engine, a gearbox and a universal shaft. The diesel engine and the universal shaft are respectively connected to the gearbox, and the universal shaft is connected to the power end 310 of the fracturing pump. In this way, the fracturing pump is driven by the gearbox and the universal shaft with the diesel engine as the power to fracture the oil layer and achieve the purpose of increasing the production of the oil well.

[0108] The fracturing pump detection system 100 included in the fracturing equipment 1 in the embodiment of the present application has the same structure and beneficial effects as the fracturing pump detection system 100 in the previous embodiment. The structure and beneficial effects of the fracturing pump detection system 100 have been described in detail in the previous embodiment and will not be repeated here.
