Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for hydrate-containing slurries, and in particular to a method and apparatus for evaluating the synergistic anti-clogging effectiveness based on a near-wall anti-clogging enhancement domain. Background Technology

[0002] In the research and engineering application of hydrate-containing slurry anti-clogging, common evaluation methods often rely on a single outcome indicator. For example, researchers may only compare the pressure drop increase under different schemes, or only compare particle deposition rate, clogging probability per unit time, local adhesion amount, or reagent consumption. Although such indicators can reflect the merits of a scheme from a certain perspective, they often fail to reveal the true synergistic effect of the inhibitor-coating combination, especially failing to accurately characterize the local protection capability in the near-wall region.

[0003] The region where hydrate blockage initiation typically first occurs is the near-wall boundary layer. This region exhibits a large velocity gradient, strong heat and mass transfer, and long particle residence time. Furthermore, the wettability, surface energy, and microstructure near the wall significantly influence particle adhesion and slippage behavior. If a combined treatment scheme has only a moderately effective overall performance across the entire cross-section, but forms a stable and appropriately thick, highly efficient protective layer in the near-wall region, its engineering application value may be higher than another scheme that only performs well on a global average.

[0004] Existing evaluation frameworks typically analyze reagent performance, coating performance, cost indicators, and environmental indicators separately, lacking an intermediate technical object that can link these factors through the actual near-wall protection capability. Therefore, it is difficult to determine whether the effect of a particular solution comes from bulk inhibition, interface weakening, or from the true synergistic effect of the inhibitor and the coating.

[0005] The so-called near-wall anti-clogging enhancement zone refers to a local boundary functional area formed within a certain space close to the pipe wall due to the combined effects of inhibitors, coatings, and operating conditions. This area possesses higher effective inhibitor concentrations, lower particle adhesion tendency, lower deposition growth rate, and higher slip / resuspending capabilities. Quantitatively evaluating the thickness, stability, protective strength, and overall cost of this zone can provide an operational basis for prioritizing different combined treatment schemes.

[0006] Furthermore, engineering selection must consider not only the anti-fouling effect itself, but also cost and environmental constraints. A certain combined approach may significantly suppress deposition, but its practical usability will be greatly reduced if it requires extremely high reagent concentrations, frequent maintenance, or incurs a large environmental burden. Therefore, it is necessary to incorporate near-wall protection effectiveness, cost, and environmental indicators into a unified technical framework, ultimately providing comprehensive recommendations that can guide the selection of critical pipe sections. Summary of the Invention

[0007] The purpose of this invention is to provide a method and apparatus for evaluating the synergistic anti-clogging effectiveness based on a near-wall anti-clogging enhancement domain. This addresses the problems of existing evaluation methods that overemphasize global average indicators, neglect local near-wall protection capabilities, struggle to quantify the synergistic effect of inhibitor-coating combinations, and fail to simultaneously integrate effects, cost, and environmental constraints. This invention is applicable to the evaluation of inhibitor-coating combination schemes in pipelines containing hydrated slurries, oil-gas mixed transport media, and slurries containing solid particles. It can be used for a unified quantitative comparison of near-wall protection capabilities, deposition inhibition capabilities, slip / resuspension improvement capabilities, rheological pressure drop effects, cost, and environmental impact.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] Based on the physical state data, calculate the characteristic parameters of the near-wall physical protection area corresponding to the near-wall anti-blocking reinforcement domain;

[0013] Based on the aforementioned characteristic parameters and preset operating condition adaptation conditions, combined with cost parameters, a synergistic anti-clogging efficiency index is calculated.

[0035] Figure 2 This is a schematic diagram of the near-wall anti-blocking reinforcement zone. Detailed Implementation

[0036] The technical solution of the present invention will be further described below with reference to specific embodiments and accompanying drawings, but the present invention is not limited to specific embodiments.

[0037] Example 1

[0038] like Figure 1 As shown, this embodiment provides a method for evaluating the collaborative anti-blocking effectiveness based on a near-wall anti-blocking enhancement domain, including:

[0039] Step S100: Obtain the inhibitor-coating combination scheme; obtain the physical state data of the near-wall anti-clogging reinforcement domain of the target pipeline, wherein the physical state data is used to characterize the local physical protection state of the near-wall anti-clogging reinforcement domain.

[0040] In this embodiment, the physical state data includes: near-wall inhibitor distribution data, deposition and slip mechanics data, and rheological and pressure drop data. Specifically, the near-wall inhibitor distribution data reflects the enrichment and gradient distribution of the anti-blocking active material near the wall; the deposition and slip mechanics data characterizes the adhesion strength and resuspension ease of particles in the near-wall region; and the rheological and pressure drop data reflects the impact of the combined scheme on the macroscopic flow behavior of the fluid and is an important constraint for evaluating the engineering applicability.

[0041] Step S200: Based on the physical state data, calculate the characteristic parameters of the near-wall physical protection area corresponding to the near-wall anti-blocking reinforcement domain.

[0042] The characteristic parameters include: reinforcement domain thickness, equivalent protection strength, and reinforcement domain stability. Reinforcement domain thickness describes the spatial scale of the effective protection range, equivalent protection strength quantifies the mechanical stability of the protective layer, and reinforcement domain stability characterizes the continuous effectiveness of the protective layer over time.

[0043] Step S201: Based on the near-wall inhibitor concentration gradient threshold or particle adhesion probability threshold in the near-wall inhibitor distribution data, determine the spatial boundary of the near-wall anti-blocking enhancement domain to obtain the enhancement domain thickness. Specifically, as follows... Figure 2 As shown, the near-wall anti-clogging enhancement zone is located near the pipe wall or functional coating, between the main fluid and the wall surface. The thickness of the enhancement zone does not refer to a fixed coating thickness, but rather to the effective physical space range in the near-wall direction where it can actually perform the anti-clogging function. The basis for determining this spatial boundary can be a near-wall inhibitor concentration gradient threshold; the vertical distance between this critical position and the wall surface is the enhancement zone thickness. Alternatively, the basis for determining the spatial boundary can be a particle adhesion probability threshold; the location where the adhesion probability decreases below this threshold is defined as the outer boundary of the enhancement zone.

[0044] Step S202: Based on the deposition and slip mechanical properties data, obtain the slip critical shear condition and the deposition layer adhesion strength, and calculate the equivalent protection strength based on the ratio of the slip critical shear condition to the deposition layer adhesion strength. The equivalent protection strength is used to comprehensively characterize the ability of the near-wall anti-clogging reinforcement domain to resist external fluid erosion. The slip critical shear condition refers to the minimum wall shear stress required for the deposited particles to slip or peel off as a whole; the deposition layer adhesion strength refers to the adhesion or cohesion between the deposited particles and the wall surface (or coating surface). The ratio of the two constitutes an antagonistic index: when the ratio is greater than or equal to 1, it means that the shear force applied by the fluid is sufficient to overcome the particle adhesion force, the deposition layer is in an unstable state that is easily removed, and the equivalent protection strength is low; conversely, when the ratio is less than 1, it indicates that adhesion force dominates, and the deposition layer is difficult to remove by erosion. If the deposit is a harmful blockage, the protection fails. However, if the deposit has been modified into a loose, soft layer by inhibitors, a low ratio may actually indicate good self-cleaning potential. Therefore, in actual evaluation, the interpretation of equivalent protection strength needs to be based on a comprehensive judgment in combination with the physical properties of the sediments.

[0045] Furthermore, considering that high-viscosity fluids may incur significant energy costs while improving apparent protection strength, this embodiment also includes a rheological side effect correction mechanism. Based on rheological and pressure drop data, a rheological side effect correction coefficient is calculated; this coefficient is then used to correct the equivalent protection strength or the stability of the reinforcement domain.

[0046] Step S300: Based on the characteristic parameters and preset working condition adaptation conditions, combined with cost parameters, calculate the synergistic anti-clogging efficiency index. The synergistic anti-clogging efficiency index is used to characterize the anti-clogging synergistic effect of the inhibitor-coating combination scheme in the target pipeline.

[0047] The operating condition adaptation conditions include: the physical risk level of the target pipe section, physical stability under extreme operating conditions, and long-term physical degradation rate. The physical risk level of the pipe section is a physical risk classification based on pipe geometry (such as elbow curvature and diameter ratio) and flow field characteristics (such as secondary flow intensity and shear rate distribution), used to characterize the inherent physical tendency of the pipe section to become clogged. Physical stability under extreme operating conditions refers to the ability of the combined scheme to maintain the integrity of the near-wall anti-clogging reinforcement domain under transient physical disturbances such as temperature abrupt changes, shutdown and restart, or high solids content shocks. It is usually quantified by monitoring the rate of change of the reinforcement domain thickness or equivalent protection strength before and after the disturbance. The long-term physical degradation rate refers to the rate at which the anti-clogging performance naturally degrades due to coating wear, inhibitor consumption, or interface aging as the transportation time increases. It replaces the non-technical maintenance cost indicators in traditional evaluations, directly constraining the engineering applicability of the scheme from the perspective of physical lifespan. The cost parameters include information such as reagent costs, coating costs, and maintenance costs. Specifically:

[0048] Step S301: Normalize the characteristic parameters, operating condition adaptation conditions, and cost parameters to obtain normalized characteristic parameters and normalized operating condition adaptation conditions.

[0049] Step S302: Based on the physical risk level of the target pipe segment, dynamically allocate the fusion weights corresponding to each normalized parameter, and perform weighted summation on the normalized parameters to obtain the collaborative anti-blocking efficiency index.

[0050] In existing technologies, the weights of evaluation indicators are usually fixed, but this is not suitable for the actual situation of pipeline engineering. Under real working conditions, the dominant mechanisms of blockage failure in pipe sections with different physical risk levels are completely different, so the focus of evaluation should also shift accordingly. This embodiment has a pre-built mapping relationship library between the physical risk level of pipe sections and the weight vector. When the physical risk level of the target pipe section is identified, the corresponding weight configuration is automatically called.

[0051] The following examples illustrate two typical engineering scenarios:

[0052] In the first scenario, when the target pipe segment is identified as a high-risk area such as an elbow, tee, or valve, blockage often manifests as instantaneous particle accumulation or protective layer peeling due to the strong secondary flow, local stagnation, or high shear scouring at these locations. In this case, the system will automatically increase the proportion of "equivalent protection strength" and "enhanced domain stability" in the fusion weights, while appropriately reducing the weight of "long-term operating physical attenuation rate".

[0053] In the second scenario, when the target pipe segment is identified as a long straight pipe segment, the flow field is relatively stable and the risk of instantaneous scouring is low. However, the long transport cycle makes the sustainability of anti-clogging effectiveness the main challenge. In this case, the system will automatically increase the fusion weights of "long-term operating physical attenuation rate" and "enhanced domain thickness" to reduce the sensitivity to instantaneous slip performance.

[0054] Step S303: The normalized parameters are weighted and summed based on the fusion weights to obtain the collaborative anti-blocking efficiency index.

[0055] The generation process of the synergistic anti-clogging effectiveness index is essentially a process of integrating and matching characteristic parameters, operating condition adaptation conditions, and cost parameters. The index directly reflects whether the inhibitor-coating combination scheme can achieve the expected synergistic anti-clogging effect under specific physical conditions. For example, although a certain scheme may have a large reinforcement domain thickness in static testing, its stability under high-shear operating conditions is poor, and its synergistic anti-clogging effectiveness index will decrease accordingly. This method enables a dynamic and comprehensive evaluation of the technical performance of the combination scheme, ensuring the engineering application value of the evaluation results.

[0056] In some embodiments, based on the collaborative anti-blocking effectiveness index, engineering selection recommendations are generated, including comprehensive level, scheme ranking, applicable working conditions, recommended filling range, recommended applicable pipe section type, and retesting recommendations. A comprehensive evaluation of multiple candidate combined schemes was conducted. The results showed that: Schemes A1 and A2 scored 72 and 88 points respectively, and were classified as Grade A (preferred recommendation), with near-wall physical protection characteristics of "high equivalent protection strength and excellent slip enhancement rate," but their "long-term operating physical attenuation rate" was average; Schemes B1 and B2 scored 76 and 81 points respectively, and were classified as Grade B (usable), with characteristics of "low long-term operating physical attenuation rate and stable reinforcement domain thickness," while their "instantaneous slip performance" was moderate; Schemes C1 and C2 scored only 65 and 58 points respectively, and were classified as Grade C (requires optimization).

[0057] Example 2

[0058] This embodiment provides a collaborative anti-blocking effectiveness evaluation device based on a near-wall anti-blocking reinforcement domain, used to implement the method described in Embodiment 1, including a near-wall physical state acquisition module, a reinforcement domain feature calculation module, and a collaborative effectiveness evaluation module.

[0059] The near-wall physical state acquisition module is used to acquire physical state data of the near-wall anti-clogging enhancement zone of the target pipeline. This physical state data characterizes the local physical protection state of the near-wall anti-clogging enhancement zone. Specifically, this module is configured as the device's data sensing interface, responsible for connecting to various sensing devices (such as optical detection units, shear testing units, pressure drop acquisition units, etc.) in external test pipe sections or circulation loops, and converting the acquired raw signals into standardized digital quantities. It is important to emphasize that this module does not simply record the global average value during data acquisition. Instead, it uses spatial resolution filtering or near-wall region reconstruction algorithms to specifically extract state information that reflects the microscopic physical environment of the near-wall anti-clogging enhancement zone. For example, when receiving full-section concentration distribution data from a fluorescence tracer sensor, this module will extract valid data segments according to a preset near-wall region definition (such as the area within a certain distance from the wall), thereby ensuring that the output physical state data truly carries the information density of the local physical protection state.

[0060] The enhanced domain feature calculation module is used to calculate the characteristic parameters of the near-wall physical protection area corresponding to the near-wall anti-blocking enhanced domain based on the physical state data. Specifically, this module is communicatively connected to the near-wall physical state acquisition module and is configured to receive the standardized physical state data and perform mapping operations from discrete physical quantities to structured feature parameters. Internally, this module integrates various physical model algorithms, capable of transforming abstract raw data into indicators with clear engineering physical meaning. For example, it uses a concentration gradient analysis algorithm to convert inhibitor distribution data into enhanced domain thickness, or uses a mechanical ratio model to convert deposition slip test data into equivalent protection strength.

[0061] The synergistic effectiveness evaluation module is used to calculate a synergistic anti-clogging effectiveness index based on the characteristic parameters and preset operating condition adaptation conditions, combined with cost parameters. This index characterizes the synergistic anti-clogging effect of the inhibitor-coating combination scheme in the target pipeline. Specifically, this module receives characteristic parameters from the enhancement domain feature calculation module and, combined with externally input or pre-stored operating condition adaptation conditions (such as pipe segment physical risk level, long-term operating physical attenuation rate, etc.) and cost parameter data, performs multi-dimensional weighted fusion calculations. The module internally stores a dynamic weight allocation strategy library, which can automatically adjust the contribution of each evaluation indicator according to the physical attributes of the current operating condition, thereby generating a synergistic anti-clogging effectiveness index that reflects the true engineering value.

[0062] In other embodiments, the device further includes an engineering suggestion output module, which outputs a comprehensive level, scheme ranking, applicable working conditions, suggested refilling range, suggested applicable pipe section type, and retesting suggestions based on the collaborative anti-blocking efficiency index.

[0063] This embodiment also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the method described in embodiment 1.

[0064] This embodiment also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in Embodiment 1.

[0065] In summary, this invention proposes a quantifiable evaluation object—the near-wall anti-clogging enhancement domain—and incorporates the near-wall protection effect, deposition slip behavior, rheological pressure drop response, cost, and environmental impact of the inhibitor-coating combination scheme into a single evaluation system, forming an engineering-operable method and device for evaluating synergistic anti-clogging effectiveness. This scheme can support candidate scheme screening, differentiated evaluation of key pipe sections, assessment of applicability under extreme conditions, and engineering selection output.
