Description

Technical Field

[0001] The present invention relates to the technical field of mud performance adjustment, and in particular to a method for adaptively adjusting mud performance in horizontal directional drilling based on big data analysis. Background Art

[0002] Horizontal directional drilling (HDD) technology is increasingly being used in various underground projects due to its high efficiency and environmentally friendly advantages. However, controlling mud properties during drilling has always been a critical step in ensuring drilling stability and construction safety. Traditional mud mixing methods rely primarily on empirical formulas and preset ratios, often based on static experimental data and historical engineering cases. When faced with complex geological conditions and uneven interlayer distribution, this approach is prone to problems such as insufficient or excessive mud supply and inaccurate performance matching, which can affect drilling efficiency and even pose safety risks.

[0003] In addition, the lack of effective technical means for real-time matching of drilling trajectories and underground geological information makes it difficult for traditional methods to achieve accurate mud demand prediction and dynamic regulation, which restricts the improvement of overall project quality. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a method for adaptively adjusting the mud performance of horizontal directional drilling based on big data analysis, which solves the problems of inaccurate mud performance matching and unreasonable resource utilization in traditional horizontal directional drilling construction.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for adaptively adjusting mud performance in horizontal directional drilling based on big data analysis, comprising:

[0006] Step 1: Based on the geological survey results, determine the height of different geological layers from the ground. Then, based on the working depth of the horizontal directional drill and the height of different geological layers from the ground, confirm the geological layer where the horizontal directional drill is located;

[0007] Step 2: Through pre-construction route survey and design, select the construction path of the horizontal directional drilling. Based on the construction path of the horizontal directional drilling, determine the geological layers that the horizontal directional drilling will pass through and the path distance through the geological layers. According to the path distance through different geological layers, the corresponding mud demand is determined;

[0008] Step 3: Pre-confirm the next target geological layer to be reached during horizontal directional drilling and the mud demand required for the next target geological layer to be reached, determine the mud mixing method in the mud mixing area, and mix the mud demand required for the target geological layer in the mud mixing area;

[0009] Step 4: During the process of combined preparation of circulating mud, pre-determine the performance of the circulating mud to obtain the performance gap between the performance of the mud required for the target geological layer, and perform the preparation of adding solvents in combination with the performance gap to achieve the mud performance required for the target geological layer;

[0010] Step 5: After the preparation is completed, when the horizontal directional drill enters the next target geological layer reached, uniformly transport the mud demand in the mud preparation area to the mud inlet pump area.

[0011] As a further solution of the present invention: In the above-mentioned Step 2, the specific method for determining the geological layer passed by the horizontal directional drill and the path distance of the passed geological layer is as follows:

[0012] Underground geological stratification model construction: According to the results of previous geological surveys, determine the depth, thickness and spatial distribution of each geological layer;

[0013] Based on the construction path of the horizontal directional drill, obtain the corresponding borehole trajectory data of the horizontal directional drill, and perform spatial superposition calculation on the borehole trajectory data and the underground geological stratification model to determine the path distance passed by the borehole of the horizontal directional drill in different geological layers.

[0014] As a further solution of the present invention: The specific method for confirming the corresponding mud demand according to the path distance passing through different geological layers is as follows:

[0015] Determine the mud demand benchmark coefficient through the following formula :

[0016]

[0017] where \(1\leq i\leq n\), and \(n\) represents the total number of different geological layers passed by the horizontal directional drill; is a function describing the physical properties of the geological layer; is the stress and fracturing risk assessment value of the formation during drilling; is the expected additional mud demand compensation; is the correction coefficient;

[0018] Combined with the mud demand benchmark coefficient and the path distance of the corresponding geological layer , construct a mud demand coupling model to determine the mud demand of the corresponding geological layer.

[0019] As a further solution of the present invention: In the above-mentioned Step 3, the mud preparation methods in the mud preparation area include the original set preparation method and the combined preparation method of circulating mud.

[0020] As a further solution of the present invention: The specific content for determining the mud preparation method in the mud preparation area is as follows:

[0021] Filter the mud liquid in the mud pit to obtain purified circulating mud liquid, and store the circulating mud liquid in the mud storage area. Determine in real time whether the storage volume of the circulating mud liquid in the mud storage area is greater than the mud demand required for the target geological layer:

[0022] If the storage volume of the circulating mud liquid is greater than or equal to the mud demand required for the target geological layer, then perform the combined blending method of the circulating mud liquid;

[0023] Otherwise, perform the original set blending method.

[0024] As a further solution of the present invention: in the fourth step, during the combined blending process of the circulating mud liquid, first determine the performance of the circulating mud liquid, obtain the performance gap with the mud performance required for the target geological layer, and combine the performance gap to perform the blending of adding solvents to achieve the specific method of the mud performance required for the target geological layer as follows:

[0025] Obtain the key performance parameters of the circulating mud liquid, including: viscosity, density, and filtration loss; and preprocess the performance parameters to obtain the set of key performance parameters of the circulating mud liquid, denoted as:

[0026]

[0027] Among them, is the viscosity performance parameter, is the density performance parameter, is the filtration loss performance parameter;

[0028] Obtain the set of mud performance parameters required for the pre-set target geological layer :

[0029]

[0030] Among them, is the viscosity performance parameter required for the target geological layer, is the density performance parameter required for the target geological layer, is the filtration loss performance parameter required for the target geological layer;

[0034] Then, through the following formula, the comprehensive value of each performance gap in the performance gap set is determined :

[0035]

[0036] where j = 1, 2, 3, is the weight coefficient of the importance of each performance gap.

[0037] As a further solution of the present invention: It further includes:

[0038] Combined with the magnitude of the comprehensive value of each performance gap in the performance gap set, a descending order is performed, and relevant solvents are added in sequence to adjust the performance of the circulating mud to reach the mud performance required for the target geological layer.

[0039] As a further solution of the present invention: In the fifth step, it further includes:

[0040] When the mud demand in the mud preparation area is uniformly transported to the mud inlet pump area, then the next target geological layer reached by the horizontal directional drill is confirmed again, and the mud demand required for the next reached geological layer is obtained. After completion of the preparation, when the horizontal directional drill enters the next reached geological layer, the mud demand in the mud preparation area is uniformly transported to the mud inlet pump area, and so on until there is no next target geological layer to be reached.

[0041] The present invention provides a method for adaptive adjustment of horizontal directional drill mud performance based on big data analysis. Compared with the prior art, it has the following beneficial effects:

[0042] The present invention realizes the full-process optimization of the adaptive adjustment of the mud performance during the construction of the horizontal directional drill by integrating geological exploration data, borehole trajectory analysis, accurate calculation of mud demand, flexible deployment strategy, and closed-loop transportation control; each step is interconnected, enabling a scientific and dynamic system to be formed from formation confirmation to construction closed-loop management, which can not only efficiently match the engineering requirements under different geological conditions, but also greatly reduce the construction risk, improve the operation efficiency, and ensure the stability and safety of the drilling process.

[0043] The present invention realizes the precise matching and real-time correction of mud performance from prediction, preparation to actual application, effectively solving the problems such as mismatched mud performance, resource waste and potential safety hazards that traditional horizontal directional drilling may face in different strata. At the same time, by constructing an adaptive control system based on big data, the frequency of manual intervention is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] Embodiment 1

[0048] Please refer to Figure 1 , the present invention provides a method for adaptively adjusting the mud performance of a horizontal directional drill based on big data analysis, including;

[0049] Step 1: According to the geological exploration results, determine the height of different geological layers from the ground, and then, based on the working descent depth of the horizontal directional drill and in combination with the height of different geological layers from the ground, confirm the geological layer where the horizontal directional drill is located;

[0050] It should be noted that geological exploration needs to be carried out before the horizontal directional drill works to determine whether the geological layer meets the working requirements of the horizontal directional drill; the exploration contents include: formation distribution (such as clay, sand layer, pebble layer, rock layer, etc.), formation depth and thickness (determine the distribution range and depth of each formation underground), obstacle detection (underground pipelines, foundation residues, buried objects, etc.) and these operations;

[0051] Step 2: Through the pre-construction line survey and design, select the construction path of the horizontal directional drill. Based on the construction path of the horizontal directional drill, determine the geological layers passed by the horizontal directional drill and the path distance of the geological layers passed through, and confirm the corresponding mud demand according to the path distance of different geological layers passed through;

[0052] The specific method for determining the geological layers passed by the horizontal directional drill and the path distance of the geological layers passed through is as follows:

[0053] AS1: Construction of underground geological stratification model: Based on the previous geological exploration results, determine the depth, thickness and spatial distribution of each geological layer;

[0054] AS2: Obtain the corresponding borehole trajectory data of the horizontal directional drill based on the construction path of the horizontal directional drill, perform spatial superposition calculation on the borehole trajectory data and the underground geological stratification model, and determine the path distance that the borehole of the horizontal directional drill passes through in different geological layers;

[0055] Specifically, before construction, obtain the underground distribution of different geological layers through means such as drilling, geological sampling, and geophysical exploration (such as seismic reflection, geoelectricity, magnetic method, etc.); after these data are summarized and processed, an underground geological stratification model is constructed to determine the height from the ground surface and the spatial extension range of each layer interface;

[0056] Adopt GIS (Geographic Information System) or BIM (Building Information Modeling) technology to digitalize the exploration data and construct a three-dimensional geological model; this can more intuitively display the stratum distribution and provide an accurate model basis for subsequent superposition calculation with the borehole trajectory. Reconstruct and simulate the borehole trajectory in three dimensions through trajectory simulation software (such as borehole trajectory simulation software, tunnel design software, etc.), and output the spatial coordinate data of the borehole; these data often exist in the form of curves or discrete points and can be directly superposed and calculated with the geological model in the later stage;

[0057] Data fusion and three-dimensional superposition: Import the underground geological stratification model and the borehole trajectory data into a calculation platform (usually a CAD system, a GIS platform or a customized project management system), and use spatial superposition algorithms (such as three-dimensional cross-checking, spatial interpolation, etc.) to determine the distance that the borehole passes through in each geological layer;

[0058] The specific method for confirming the corresponding mud demand according to the path distance passing through different geological layers is as follows:

[0059] BS1: Determine the mud demand reference coefficient through the following formula :

[0060]

[0061] Among them, 1 ≤ i ≤ n, where n represents the total number of different geological layers passed by the horizontal directional drill; is a function describing the physical properties of the geological layer (such as permeability, clay content, porosity, etc.) and can be parametrically expressed using fuzzy logic or multiple regression analysis; is the stress and fracturing risk assessment value of the formation during drilling, reflecting the need to achieve formation stability through mud regulation; is the additional demand compensation expected for the mud during transportation and circulation due to factors such as formation temperature and mineral reactions; is a correction coefficient obtained by laboratory tests and historical engineering data inversion to ensure that the model matches the actual mud consumption;

[0062] BS2: Combine the benchmark coefficient of mud demand , and construct a coupled model of mud demand. The coupled model of mud demand is reflected by the following formula:

[0063]

[0064] where is the mud demand for the corresponding geological layer, is the actual path distance of the corresponding geological layer;

[0065] Specifically, is a function describing the physical properties of the formation and is reflected by the following formula:

[0066]

[0067] where: represents the permeability of the corresponding geological layer, represents the porosity of the corresponding geological layer, represents the clay content of the corresponding geological layer; is a regression coefficient, a regression coefficient determined by fitting a large number of on-site tests and historical data;

[0068] In this step, by constructing an underground geological stratification model and integrating borehole trajectory data, the path distance that the horizontal directional drill passes through in each geological layer is accurately calculated using spatial overlay technology, and then the mud demand under different geological layers is determined; such a calculation method not only makes the mud consumption more accurate and reasonable, avoiding engineering risks caused by excessive or insufficient mud use, but also provides a quantitative basis for on-site timely regulation; relying on the formula model and data regression analysis, factors such as formation physical properties, stress risks, and temperature-mineral reactions can be effectively compensated to ensure that the mud ratio closely matches the actual underground situation, thereby promoting the continuity and efficiency of the drilling process;

[0069] Step 3: Pre-confirm the next target geological layer reached during the horizontal directional drill construction and the mud demand required for the next target geological layer reached, determine the mud mixing method in the mud mixing area, and mix the mud demand required for the target geological layer in the mud mixing area;

[0070] The mud mixing methods in the mud mixing area include the original set mixing method and the circulating mud liquid combined mixing method;

[0071] It should be noted that the original setting and preparation is a preparation method that is pre-set by professional staff. It is a method of formulating the mud properties required for the target geological layer by mixing the provided original water, clay and a certain preparation solution;

[0072] The specific content of the mud preparation method for determining the mud preparation area is as follows:

[0073] Filter the mud liquid in the mud pit to obtain the purified circulating mud liquid, and place the circulating mud liquid in the mud storage area for storage. Judge in real time whether the storage volume of the circulating mud liquid in the mud storage area is greater than the mud demand required for the target geological layer:

[0074] If the storage volume of the circulating mud liquid is greater than or equal to the mud demand required for the target geological layer, then adopt the combined preparation method of the circulating mud liquid;

[0075] Otherwise, adopt the original setting and preparation method;

[0076] On the premise of clarifying the next target geological layer and its corresponding mud demand, this step flexibly selects the mud preparation method according to the real-time construction data, including both the original setting and preparation method and the combined preparation method of the circulating mud liquid; through this dual selection mechanism, not only the fine matching of the mud performance requirements in different construction stages is realized, but also the preparation strategy can be switched in time according to the storage volume and quality status of the circulating mud liquid on site; this not only saves raw materials, but also improves the response speed and adaptability of the mud preparation at the construction site, provides higher economy and operation flexibility for the whole drilling process, and ensures the smooth progress of the project;

[0077] Step Four: During the combined preparation process of the circulating mud liquid, first determine the performance of the circulating mud liquid to obtain the performance gap with the mud performance required for the target geological layer, and combine the performance gap to carry out the preparation by adding solvents to achieve the mud performance required for the target geological layer;

[0078] It should be noted that the mud properties required for different target geological layers are all different. Through the combined preparation method of the circulating mud liquid, the performance of the circulating mud liquid is made to reach the mud performance required for the target geological layer by a certain solvent addition ratio;

[0079] The specific method of first determining the performance of the circulating mud liquid during the combined preparation process of the circulating mud liquid to obtain the performance gap with the mud performance required for the target geological layer and combining the performance gap to carry out the preparation by adding solvents to achieve the mud performance required for the target geological layer is as follows:

[0080] CS1: Obtain the key performance parameters of the circulating mud, including viscosity, density, and filtration loss; and preprocess the performance parameters to obtain the set of key performance parameters of the circulating mud, denoted as:

[0081]

[0082] Among them, is the viscosity performance parameter, is the density performance parameter, is the filtration loss performance parameter;

[0083] It should be noted that the key performance parameters of the circulating mud are specifically determined by professional staff. In this embodiment, the key performance parameters of the circulating mud include three key performance parameters: viscosity, density, and filtration loss. In reality, there may be more key performance parameters, such as pH value and temperature, etc.

[0084] CS2: According to the engineering requirements of different target geological layers, preset the set of mud performance parameters required for the target geological layer :

[0085]

[0086] Among them, is the viscosity performance parameter required for the target geological layer, is the density performance parameter required for the target geological layer, is the filtration loss performance parameter required for the target geological layer;

[0087] CS3: Combine with to determine the set of performance gaps between the performance parameters of the circulating mud and the mud performance parameters required for the target geological layer :

[0088]

[0089] Among them, is the performance gap between the viscosity performance parameter and the viscosity performance parameter required for the target geological layer , is the performance gap between the density performance parameter and the density performance parameter required for the target geological layer , is the performance gap between the filtration loss performance parameter and the filtration loss performance parameter required for the target geological layer ; and , , , ;

[0090] CS4: Then, through the following formula, determine the comprehensive value of each performance gap in the performance gap set :

[0091]

[0092] where j = 1, 2, 3, is the weight coefficient of the importance of each performance gap;

[0093] CS5: Combine the comprehensive values of each performance gap in the performance gap set and sort them from large to small, and then add relevant solvents in turn to adjust the performance of the circulating mud to the required mud performance of the target geological layer;

[0094] During the mud preparation process, by pre-determining the key performance indicators of the current circulating mud (such as viscosity, density, filtration loss, etc.) and comparing them with the performance parameters required for the target geological layer, the performance gap can be quantified, and a solvent addition plan can be formulated accordingly for preparation; this method enables the mud to be accurately adjusted to the ideal state in a short time, which can not only meet the strict requirements of different formations for the physical and chemical properties of the mud, but also effectively reduce the risk of drilling accidents caused by performance mismatch; through comprehensive sorting and gradual adjustment, it is ensured that the mud preparation process has high pertinence and self-adaptability, thereby improving the stability, continuity and construction quality of the entire drilling project;

[0095] Step Five: After the preparation is completed, when the horizontal directional drill enters the next reached target geological layer, uniformly transport the mud demand in the mud preparation area to the mud inlet pump area;

[0096] It should be noted that during the construction process of the horizontal directional drill, corresponding construction is carried out through the circulation cooperation principle of the mud and the HDD equipment, and the process is as follows:

[0097] The mud is sent from the mud pump into the inside of the drill pipe and reaches the drill bit or reamer directly;

[0098] The mud flushes the drill bit, carries the drill cuttings, and returns to the ground from the borehole;

[0099] The returned mud enters the return mud pit and is filtered through a screen / desander;

[0100] The purified mud re-enters the mud tank, is adjusted and then pumped again;

[0101] After the mud preparation is completed, in Step 5, the prepared mud is uniformly transported to the mud inlet pump area, forming a close circulation cooperation with the drilling equipment, realizing the integrated management of automatic mud transportation and on-site construction; this step not only ensures the continuous supply of mud during the drilling process, improves the stability of the drill hole, but also forms a closed-loop control mechanism by monitoring the transportation and mud recovery in real time and then entering the preparation link again.

[0102] Embodiment 2

[0103] In the specific implementation process of this embodiment, based on Embodiment 1 and different from Embodiment 1, in Step 5, it further includes:

[0104] When the mud demand in the mud preparation area is uniformly transported to the mud inlet pump area, then confirm again the next target geological layer reached by the horizontal directional drill, obtain the mud demand required for the next reached geological layer, and after the preparation is completed, when the horizontal directional drill enters the next reached geological layer, uniformly transport the mud demand in the mud preparation area to the mud inlet pump area, and so on until there is no next target geological layer.
