Description

Technical Field

[0001] This invention relates to the field of oilfield fracturing pump technology, specifically to a detection system and method for detecting fracturing fluid packing leakage. Background Technology

[0002] Fracturing pumps are the core equipment used in hydraulic fracturing operations in oil and gas field development. Their function is to inject fracturing fluid (containing proppant, chemical additives, etc.) into underground oil and gas reservoirs at high pressure and large volume. The impact force of the fracturing fluid creates fractures in the rock formation, thereby improving the flow channels of oil and gas and increasing the oil and gas recovery rate.

[0003] In practical applications, packing seals are used between the plunger and pump head of a fracturing pump. During operation, the plunger and packing reciprocate. To ensure the normal operation of the fracturing pump, a reliable seal between the packing and plunger must be maintained to prevent fracturing fluid leakage from the packing. Fracturing fluid contains fine particles such as quartz sand or ceramsite. As the fracturing fluid is a high-pressure liquid during pump operation, it easily causes packing wear failure. Packing wear failure is a slow process; if it is not detected and replaced in time, it can easily damage the packing assembly hole on the pump head, rendering the pump head unusable and affecting operations. Furthermore, repairing damaged packing assembly holes on the pump head can result in significant economic losses.

[0004] Currently, the industry typically uses manual inspections after each fracturing operation to detect packing failures. However, manual inspections have limitations, such as failing to detect problems in a timely manner or failing to effectively identify early issues. This can lead to the failure of packing to be replaced promptly, resulting in the risk of pump head damage. Summary of the Invention

[0005] In view of this, the present invention provides a detection system and method for fracturing fluid packing leakage, in order to solve the problem that the poor timeliness of manual inspection in the prior art leads to failure of faulty packing and damage to the pump head.

[0006] In a first aspect, the present invention provides a detection system for fracturing pump packing leakage. The fracturing pump packing leakage detection system includes: an integrated unit located below the fracturing pump packing and connected to the pump head housing; the integrated unit includes a component detection sensor for detecting the concentration information of a target component of the liquid at the fracturing pump packing; and a control unit electrically connected to the component detection sensor, which determines whether there is fracturing fluid leakage at the fracturing pump packing based on the concentration information of the target component.

[0007] In this embodiment, an integrated unit is installed below the packing of the fracturing pump. The integrated unit mainly includes a component detection sensor, which is used to detect the concentration information of the target components of the liquid at the packing of the target fracturing pump. The target components include at least chlorine, iron, and phosphorus. The control unit is electrically connected to the component detection sensor, so that the control unit can receive the concentration information of the target components collected by the component detection sensor and further determine whether there is a fracturing fluid leak at the packing based on the information. When the control unit detects a fracturing fluid leak at the packing, it indicates that the packing of the fracturing pump has failed and can no longer be used. This setting further improves the detection efficiency and accuracy of the packing of the fracturing pump and solves the technical problem in the prior art where untimely manual inspections lead to failure to detect faulty packing in time, resulting in pump head damage.

[0008] In one optional embodiment, the component detection sensor includes an ion sensor for detecting the concentration of a target ion, wherein the target ion includes at least one or more of the following ions: chloride ions, iron ions, and phosphorus ions. By incorporating an ion sensor, highly selective detection of specific ions can be achieved through a selective electrode or a chemically sensitive membrane, avoiding interference from other ions.

[0009] In one optional implementation, a component detection sensor is used to detect the concentration information of target components in the fluid at the packing of the fracturing pump under a target environment, including a rainwater environment. A specific sensor targeting target ions (chloride, iron, and phosphorus ions) can ignore irrelevant components in the rainwater itself (such as common sodium and calcium ions in rainwater), focusing only on characteristic ions relevant to equipment operation. This allows for accurate identification of leak signals even in complex environments with rainwater dilution and impurities, avoiding false alarms or missed alarms. This design prevents rainwater from mixing with the leaking fracturing fluid in rainwater environments, avoiding detection errors caused by visual confusion during manual inspection.

[0010] In one optional implementation, the detection system further includes an alarm unit electrically connected to the control unit. The alarm unit is used to issue an alarm signal when the control unit determines that there is fracturing fluid leakage at the packing of the fracturing pump. This can shorten the leakage response time to the second level, preventing the leakage from accumulating over time. Under high-pressure operation of the fracturing pump, a small leak may expand into a large amount of splashing in a short time, thereby reducing fracturing fluid loss and equipment contamination.

[0011] In one alternative implementation, the integrated unit is detachably connected to the pump head housing, facilitating disassembly and relocation and improving ease of use.

[0012] Secondly, this invention also provides a method for detecting packing leakage in a fracturing pump, comprising: acquiring concentration information of target components of the liquid at the packing of the fracturing pump, wherein the target components include at least: chloride ions, iron ions, and phosphorus ions; and determining whether there is fracturing fluid leakage at the packing of the fracturing pump based on the concentration information of the target components. By detecting the concentration of the aforementioned target components, fracturing fluid can be specifically identified from complex liquids, avoiding misjudging non-fracturing fluid leaks such as rainwater and cleaning water as leaks, and significantly improving the accuracy of detection.

[0013] In one optional implementation, determining whether there is fracturing fluid leakage at the fracturing pump packing is based on the concentration information of the target component, including: determining that there is fracturing fluid leakage at the fracturing pump packing in response to the chloride ion concentration exceeding a first preset threshold, and / or, in response to the iron ion concentration exceeding a second preset threshold, and / or, in response to the phosphorus ion concentration exceeding a third preset threshold. By setting specific threshold standards and two different judgment logics, the real-time performance and accuracy of the detection are improved.

[0014] In one optional implementation, determining whether there is fracturing fluid leakage at the fracturing pump packing is based on the concentration information of the target component, including: determining that there is no fracturing fluid leakage at the fracturing pump packing in response to the chloride ion concentration being less than a first preset threshold, the iron ion concentration being less than a second preset threshold, and the phosphorus ion concentration being less than a third preset threshold. By setting specific threshold standards, the real-time performance and accuracy of the detection are improved.

[0015] In one optional implementation, based on the concentration information of the target component, it is determined whether there is fracturing fluid leakage at the packing of the fracturing pump, and then the process includes: in response to the detection of fracturing fluid leakage at the packing of the fracturing pump, generating an alarm signal, which is used to control the target equipment to trigger an alarm. By detecting abnormal concentration information of the target component using an ion sensor, the alarm signal is triggered, shortening the leakage detection time and avoiding pump head damage caused by delays.

[0016] In one optional implementation, obtaining the concentration information of the target component of the fluid at the fracturing pump packing includes: obtaining the concentration information of the target component of the fluid at the fracturing pump packing under a target environment, wherein the target environment includes at least a rainwater environment. Specific sensors for target ions (chloride ions, iron ions, phosphorus ions) prevent the mixing of rainwater and leaked fracturing fluid under rainwater conditions, avoiding detection errors caused by visual confusion during manual inspection.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0025] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0026] In practical applications, such as Figure 1 As shown, the power end 50 of the fracturing pump is connected to the pump head 10 via a double-ended stud. The power end 50 inputs the load to the pump head 10. The plunger 20 of the fracturing pump is sealed to the pump head 10 using packing 30. During the operation of the fracturing pump, the plunger 20 and the packing 30 will reciprocate. Since the components of fracturing fluid mainly include water, additives, and proppant, and the proppant contains small particles such as quartz sand or ceramsite, the packing 30 is prone to wear and failure during operation, causing fracturing fluid leakage. In related technologies, manual inspection is used to determine whether there is fracturing fluid leakage at the packing, which is inefficient and has a high error rate. There is a risk that the faulty packing will not be detected in time, resulting in failure to replace it in time and damage to the pump head.

[0027] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, in one aspect, a detection system for fracturing pump packing leakage is provided, comprising: an integrated unit 40 located below the packing 30 of the fracturing pump, the integrated unit being connected to the housing of the pump head 10, the integrated unit 40 including a component detection sensor for detecting the concentration information of a target component of the liquid at the fracturing pump packing; and a control unit electrically connected to the component detection sensor, the control unit determining whether there is fracturing fluid leakage at the fracturing pump packing based on the concentration information of the target component.

[0029] In this embodiment, an integrated unit 40 is set below the packing 30 of the fracturing pump. The integrated unit 40 mainly includes a component detection sensor, which is used to detect the concentration information of the target component of the liquid at the packing of the target fracturing pump. The target component includes at least chlorine, iron, and phosphorus. The control unit is electrically connected to the component detection sensor, so that the control unit can receive the concentration information of the target component collected by the component detection sensor and further determine whether there is a fracturing fluid leak at the packing 30 based on the information. When the control unit detects a fracturing fluid leak at the packing 30, it indicates that the packing 30 of the fracturing pump has failed and can no longer be used. This setting further improves the detection efficiency and accuracy of the packing 30 of the fracturing pump and solves the technical problem in the prior art that failure to detect faulty packing in time due to untimely manual inspection leads to pump head damage.

[0030] In one embodiment, the component detection sensor includes an ion sensor for detecting the concentration of a target ion, wherein the target ion includes at least one or more of the following ions: chloride ion, iron ion, and phosphorus ion. By incorporating an ion sensor, highly selective detection of specific ions can be achieved through a selective electrode or a chemically sensitive membrane, avoiding interference from other ions.

[0031] In one embodiment, the component detection sensor is used to detect the concentration information of the target component of the liquid at the packing of the fracturing pump in a target environment, wherein the target environment includes: a rainwater environment.

[0032] Rainy environments can exacerbate packing wear (e.g., rainwater mixing with grease leading to lubrication failure, and humid environments accelerating rubber aging). Abnormal changes in the liquid composition at the packing (e.g., detection of characteristic ions or fracturing fluid components) can directly reflect packing seal failure.

[0033] Furthermore, rainwater may dilute the fluids at the packing (such as leaked fracturing fluid or lubricating fluid) or introduce impurities into the environment (such as ions in the surface soil), interfering with the accuracy of traditional detection methods. However, specific sensors targeting specific ions (chloride, iron, and phosphorus ions) can ignore irrelevant components in rainwater (such as common sodium and calcium ions in rainwater), focusing only on characteristic ions relevant to equipment operation. This allows for accurate identification of leak signals even in complex environments with rainwater dilution and impurities, avoiding false alarms or missed alarms. This design prevents rainwater from mixing with leaked fracturing fluid in rainy environments, avoiding detection errors caused by visual confusion during manual inspection.

[0034] In one embodiment, the detection system further includes an alarm unit electrically connected to the control unit, which is used to issue an alarm signal when the control unit determines that there is fracturing fluid leakage at the fracturing pump packing.

[0035] Specifically, when the control unit determines that fracturing fluid leakage has occurred at the packing gland based on data from the component detection sensor, the alarm unit can immediately issue a clear alarm signal, such as an audible and visual alarm or equipment linkage signal, directly notifying on-site operators or the remote monitoring center. Compared to the traditional method of relying on manual inspections to detect leaks, which may have a delay of several hours or even days, the alarm unit can shorten the leak response time to the second level, preventing the leakage from accumulating over time. Under the high pressure of the fracturing pump, a small leak may expand into a large amount of splashing in a short period of time, thereby reducing fracturing fluid loss and equipment contamination.

[0036] In one embodiment, the integrated unit is detachably connected to the pump head housing. This detachable connection between the integrated unit 40 and the pump head 10 housing facilitates easy assembly and disassembly of the integrated unit 40 and allows it to be adapted to different fracturing pumps, thus improving the versatility of the detection system.

[0037] Specifically, in one embodiment, the integrated unit and the pump head housing are connected magnetically. This magnetic connection eliminates the need for mechanical fastening structures such as bolts or clips; the integrated unit can be installed or removed solely through magnetic attraction. During installation, the integrated unit is aligned with the magnetic attraction area on the pump head housing, such as a pre-set metal base, to secure it.

[0038] Magnetic connections utilize flexible magnets, such as rubber sheets or multi-point magnetic structures, to conform to the curved contours of the pump head housing, avoiding loosening caused by uneven contact surfaces in traditional mechanical connections like bolts. Furthermore, the leakage point at the packing of the fracturing pump may change position due to variations in operating conditions, such as pump shaft eccentricity or uneven packing wear. Magnetic connections allow for easy adjustment of the integrated unit's installation position according to actual testing needs. When maintaining or replacing the integrated unit, such as for sensor calibration, it can be simply peeled off.

[0039] In another embodiment, the connection between the integrated unit and the pump head housing can be made by means of magnetic adsorption, detachable bonding, or bolted fastening.

[0040] According to an embodiment of the present invention, in another aspect, a method for detecting packing leakage in a fracturing pump is also provided, comprising:

[0041] Step S101: Obtain the concentration information of the target components of the fluid at the packing of the fracturing pump. The target components include at least: chloride ions, iron ions, and phosphorus ions.

[0042] In step S101, since the liquids that may come into contact with the packing of the fracturing pump include fracturing fluid, rainwater, equipment cleaning water, lubricating oil, etc., and chloride ions, iron ions, and phosphorus ions are characteristic components of fracturing fluid, such as fracturing fluid often containing potassium chloride (chloride ions), iron ion stabilizers, phosphorus-containing crosslinking agents, etc., the natural concentration of these ions in other environmental liquids (such as rainwater) is extremely low or non-existent.

[0043] Among related technologies, detection methods based on "alarm upon liquid presence" are easily affected by environmental interference. For example, water accumulation at the base of the pipes during rainy days may be mistakenly identified as a leak.

[0044] Step S102: Based on the concentration information of the target component, determine whether there is fracturing fluid leakage at the packing of the fracturing pump.

[0045] By following the steps described above and detecting the concentration of the target components, fracturing fluid can be specifically identified from complex liquids, avoiding misjudging non-fracturing fluid leaks such as rainwater and cleaning water as leaks, and significantly improving the accuracy of detection.

[0046] In one embodiment, step S102, determining whether there is fracturing fluid leakage at the fracturing pump packing based on the concentration information of the target component, includes:

[0047] Step S1021: In response to the concentration of chloride ions exceeding a first preset threshold, and / or, in response to the concentration of iron ions exceeding a second preset threshold, and / or, in response to the concentration of phosphorus ions exceeding a third preset threshold, determine that there is fracturing fluid leakage at the packing of the fracturing pump.

[0048] Specifically, the first preset threshold is 350 mg / L, the second preset threshold is 10 mg / L, and the third preset threshold is 0.1 mg / L. That is, when the concentration of chloride ions exceeds 350 mg / L, and / or the concentration of iron ions exceeds 10 mg / L, and / or the concentration of phosphorus ions exceeds 0.1 mg / L, it is determined that there is fracturing fluid leakage at the packing of the fracturing pump.

[0049] In some optional embodiments, when the concentration of chloride ions exceeds 350 mg / L, the concentration of iron ions exceeds 10 mg / L, and the concentration of phosphorus ions exceeds 0.1 mg / L, it is determined that there is fracturing fluid leakage at the packing of the fracturing pump.

[0050] In some optional embodiments, a fracturing fluid leak is determined to be present at the packing of the fracturing pump when the concentration of chloride ions exceeds 350 mg / L, or the concentration of iron ions exceeds 10 mg / L, or the concentration of phosphorus ions exceeds 0.1 mg / L.

[0051] By setting specific threshold standards and two different judgment logics, the real-time performance and accuracy of detection are improved.

[0052] In one embodiment, determining whether there is fracturing fluid leakage at the fracturing pump packing based on the concentration information of the target component includes:

[0053] Step S1022: In response to the concentration of chloride ions being less than the first preset threshold, and in response to the concentration of iron ions being less than the second preset threshold, and in response to the concentration of phosphorus ions being less than the third preset threshold, it is determined that there is no fracturing fluid leakage at the packing of the fracturing pump.

[0054] In some optional embodiments, when the concentration of chloride ions is less than 350 mg / L, the concentration of iron ions is less than 10 mg / L, and the concentration of phosphorus ions is less than 0.1 mg / L, it is determined that there is no fracturing fluid leakage at the packing of the fracturing pump.

[0055] In one embodiment, step S102: Based on the concentration information of the target component, determine whether there is fracturing fluid leakage at the packing of the fracturing pump, followed by:

[0056] Step S102: In response to a fracturing fluid leak at the packing of the fracturing pump, an alarm signal is generated. The alarm signal is used to control the target equipment to trigger an alarm.

[0057] An abnormal concentration of the target component is detected by an ion sensor, triggering an alarm signal, which shortens the time to detect leaks and avoids pump head damage caused by delays.

[0058] In one embodiment, step S101: obtaining the concentration information of the target component of the fluid at the packing of the fracturing pump, including:

[0059] Step S1011: Obtain the concentration information of the target component of the liquid at the packing of the fracturing pump under the target environment, wherein the target environment includes at least: rainwater environment.

[0060] By using specific sensors targeting ions (chloride ions, iron ions, and phosphorus ions), the mixing of rainwater and leaked fracturing fluid in rainy environments is avoided, thus preventing detection errors caused by visual confusion during manual inspection.
