[0027] Application Overview

[0028] Oil and gas well fracturing technology refers to the technology of using water conservancy to form a crack in the oil and gas layer during oil or gas production. It is one of the main measures to increase production in the middle and late stages of oil and gas production. In the process of oil production, the production increase effect of fracturing technology is very obvious, and it is widely used in the development of various oil fields. Therefore, many domestic oil fields use fracturing technology to improve the recovery rate of oil fields. However, the large amount of sewage generated during fracturing operations not only affects the environment, but also causes a waste of water resources. How to use computer technology to improve the efficiency of intelligent sewage treatment in the fracturing fluid system and realize the recycling of sewage in the fracturing fluid system is of great significance for protecting the environment, saving water resources, and reducing the cost of fracturing operations.

[0029] In the prior art, a large amount of wastewater is generated when fracturing technology is used to increase oil field production. The wastewater is usually treated by filtration and chemical flocculation. The entire wastewater treatment process is complex, time-consuming, and has technical problems such as high manpower and material costs.

[0030] In response to the above technical problems, the overall idea of ​​the technical solution provided by this application is as follows:

[0031] The present application provides a method for utilizing wastewater based on a recyclable clean fracturing fluid system, and the method is applied to a wastewater utilization system based on a recyclable clean fracturing fluid system, wherein the method comprises: obtaining a water quality standard of the clean fracturing fluid system; obtaining first wastewater information; obtaining a first pretreatment instruction; performing a standard test on the first wastewater according to the first pretreatment instruction to obtain second wastewater component information and second component content information of the first wastewater information; inputting the second wastewater component information and the second component content information into a wastewater treatment scheme matching model to obtain a first treatment scheme; treating the first wastewater according to the first treatment scheme to obtain first purified water; and mixing the first purified water with a recyclable clean fracturing fluid thickener.

[0032] After introducing the basic principles of the present application, various non-limiting implementation methods of the present application will be specifically described below in conjunction with the drawings in the specification.

[0033] Embodiment 1

[0034] Please see attached Figure 1 The embodiment of the present application provides a method for utilizing wastewater based on a recyclable clean fracturing fluid system, wherein the method is applied to a wastewater utilization system based on a recyclable clean fracturing fluid system, and the method specifically comprises the following steps:

[0035] Step S100: obtaining water quality standards of a clean fracturing fluid system;

[0036] Specifically, the wastewater utilization method based on a recyclable clean fracturing fluid system is applied to the wastewater utilization system based on a recyclable clean fracturing fluid system. A corresponding computer model can be constructed through intelligent wastewater pretreatment, so as to intelligently formulate targeted wastewater treatment plans, thereby achieving the technical goal of intelligent treatment and recycling of wastewater in the fracturing fluid system, and achieving the technical effect of improving the treatment efficiency and treatment quality of wastewater in the fracturing fluid system, and then intelligently mixing and recycling.

[0037] Fracturing operation technology refers to the technology of using hydraulic effects to form a crack in the oil layer during oil production. The fracturing fluid is essentially a working fluid used in fracturing operations, which can transfer the high pressure formed by ground equipment to the formation, that is, to form a crack in the oil layer. Correspondingly, the fracturing fluid system, that is, the chemical system of the working fluid used in fracturing operations, is made of a variety of additives in a certain ratio. The water quality standard of the clean fracturing fluid system is obtained by consulting data through big data, or obtaining relevant national, industry and other standards based on actual conditions. Among them, the water quality standard of the clean fracturing fluid system refers to the required data on the components corresponding to the water quality, the content of each component, etc. in the fracturing fluid used in oil production. By obtaining the water quality standard of the clean fracturing fluid system, the water quality standard that can be used for the circulating clean fracturing fluid system is achieved, and the technical effect of clarifying the sewage treatment target is also achieved.

[0038] Step S200: obtaining first sewage information;

[0039] Specifically, when using fracturing technology to extract oil or gas, different wastewater will be generated based on the actual oil and gas extraction conditions at different stages and in different operating oil wells, including differences in water quality components, suspended solids in water, pH value, mineralization and other data indicators.

[0040] The first sewage information refers to any sewage information to be treated generated during the fracturing operation, including sewage generation stage, sewage volume and other related sewage data. By obtaining the first sewage information, a sewage utilization system based on a recyclable clean fracturing fluid system is used to treat the sewage, thereby providing a sewage foundation for achieving the goal of sewage recycling.

[0041] Step S300: obtaining a first preprocessing instruction;

[0042] Step S400: performing standard testing on the first sewage according to the first pre-processing instruction to obtain second sewage component information and second component content information of the first sewage information;

[0043] Specifically, when the sewage utilization system based on the recyclable clean fracturing fluid system obtains the first sewage information, that is, the sewage to be treated, the first pretreatment instruction is automatically triggered. The first pretreatment instruction is used to perform standard testing on the first sewage. Through the first pretreatment instruction, the system intelligently performs a water quality standard test on the first pretreatment instruction, thereby obtaining data on the types of substances in the first sewage, data on the corresponding content of each substance, and other related information, namely, the second sewage composition information and the second component content information. For example, after the system is processed, it is confirmed that there is sodium ion 1185.6ρ / (mg·L -1 ), calcium ion 22ρ / (mg·L -1 ), magnesium ion 5.65ρ / (mg·L -1 ), etc., wherein sodium ions, calcium ions and magnesium ions are the components of sewage. Through pretreatment, the actual components and contents of the first sewage are clarified, providing a technical effect for subsequent sewage treatment targets.

[0044] Step S500: inputting the second sewage component information and the second component content information into a sewage treatment scheme matching model to obtain a first treatment scheme;

[0045] Specifically, the second sewage component information and the second component content information are used as input data information of the sewage treatment scheme matching model. After intelligent analysis by the sewage treatment scheme matching model, a corresponding treatment scheme is matched for the first sewage, that is, based on the components and their contents in the first sewage, a corresponding treatment scheme is formulated in a targeted manner, thereby obtaining the first treatment scheme. Among them, the sewage treatment scheme matching model is an intelligent neural network model, which is obtained through training with a large amount of sewage data information and has the functions of intelligent sewage analysis and intelligent treatment scheme matching. In addition, the first treatment scheme takes the water quality standard of the clean fracturing fluid system as the target, and after a series of cleaning treatment operations, the first sewage is made to meet the corresponding water quality standard. The technical effect of formulating corresponding treatment schemes based on the actual situation of sewage and improving the adaptability of treatment schemes is achieved.

[0046] Step S600: treating the first sewage according to the first treatment scheme to obtain first purified water;

[0047] Specifically, the sewage utilization system based on the recyclable clean fracturing fluid system uses the first treatment scheme obtained by intelligent matching of the sewage treatment scheme matching model to perform intelligent clean treatment on the corresponding sewage. After the first sewage is treated by the first treatment scheme, the treatment result obtained is the first purified water. Among them, the first purified water is water that meets the water quality standard of the clean fracturing fluid system, that is, after the first sewage is treated by the first treatment scheme, the water obtained can be recycled in the fracturing fluid system. The technical effect of cleaning the sewage and making it meet the use standards of the next round of fracturing fluid is achieved, laying the foundation for subsequent recycling.

[0048] Step S700: mixing the first purified water with a recyclable clean fracturing fluid thickener.

[0049] Specifically, the first purified water obtained by intelligent treatment of the sewage utilization system based on the recyclable clean fracturing fluid system is used in the configuration of the fracturing fluid, and then enters the next round of fracturing operations, thereby forming a sewage circulation method for the fracturing fluid system. By using computer technology, the sewage in the fracturing fluid system is intelligently acquired and controlled, and targeted sewage pretreatment is performed, so as to clarify the various components and their contents in the sewage, further construct a sewage treatment scheme matching model, and intelligently formulate targeted sewage treatment schemes, and finally realize intelligent sewage treatment, forming a sewage recycling system for the fracturing fluid system. By constructing a corresponding computer model through intelligent sewage pretreatment, a targeted sewage treatment scheme is intelligently formulated, achieving the technical goal of intelligent treatment and recycling of sewage in the fracturing fluid system, and achieving the technical effect of improving the sewage treatment efficiency and treatment quality of the fracturing fluid system, and then intelligently mixing and recycling.

[0050] Further, as attached Figure 2 As shown, step S300 of the embodiment of the present application also includes:

[0051] Step S310: Performing a preliminary component test on the first sewage to obtain first sewage component information and first component content information;

[0052] Step S320: performing water treatment cost detection according to the first sewage component information and the first component content information to obtain a first detection result, wherein the first detection result is that the cost does not exceed the standard or the cost exceeds the standard;

[0053] Step S330: If the first detection result is that the cost does not exceed the standard, the first pre-processing instruction is obtained.

[0054] Specifically, before pre-treating the first sewage, the components of the first sewage are first detected to obtain the fuzzy test result of the first sewage, that is, the first sewage component information and the first component content information. Furthermore, based on the first sewage component information and the first component content information, the cost of intelligently treating the first sewage is detected and estimated to obtain the first detection result. Among them, the first detection result is two situations: the first sewage treatment cost does not exceed the standard or the first sewage treatment cost exceeds the standard. In other words, after the detection, it is estimated whether the cleaning treatment cost of the first sewage is within the allowable cost range. When the first detection result is that the first sewage treatment cost does not exceed the standard, the sewage utilization system based on the recyclable clean fracturing fluid system will issue the first pre-treatment instruction for cleaning the first sewage.

[0055] By simply testing the sewage before pretreatment, the cost of cleaning the corresponding sewage can be estimated. Only when the cost of sewage treatment does not exceed the relevant sewage treatment cost standard, the system will issue a pretreatment instruction and then clean the sewage. This avoids the problem of difficult and high-cost sewage treatment, and the waste of manpower, material resources and other resources due to blind treatment, and achieves the technical effect of improving the intelligence and reliability of sewage treatment.

[0056] Further, as attached Figure 3 As shown, step S320 of the embodiment of the present application also includes:

[0057] Step S321: constructing a cost detection model based on anomaly detection algorithm;

[0058] Step S322: obtaining historical available sewage data, wherein the historical available sewage data includes sewage component information and component content information, and predetermined treatment cost data of the available sewage data;

[0059] Step S323: training the cost detection model according to the historical available sewage data and the predetermined treatment cost data of the available sewage data, until the model reaches a stable state, thereby obtaining a first cost detection model and a second cost detection model;

[0060] Step S324: inputting the first sewage component information into the first cost detection model to obtain a second detection result;

[0061] Step S325: inputting the first component content information into the second cost detection model to obtain a third detection result;

[0062] Step S326: Obtain the first detection result according to the second detection result and the third detection result.

[0063] Specifically, before intelligently judging whether the corresponding treatment cost is within the standard range based on the initial inspection result of the first sewage composition, a computer model for estimating the relevant sewage treatment cost, i.e., the cost detection model, is first constructed. The cost detection model is constructed by an anomaly detection algorithm. The anomaly detection algorithm is a computer algorithm for intelligently detecting abnormal situations, such as network quality anomaly detection, user access behavior anomaly detection, etc. Anomalies are points that are sparsely distributed and far away from high-density groups. Commonly used anomaly detection algorithms include isolation forests, etc.

[0064] First, based on big data, the wastewater data that can be recycled during historical fracturing fluid operations are collected, including wastewater composition information and its component content information, and available wastewater data predetermined processing cost data. Further, a computer model is trained based on the wastewater composition information until the model converges, and the first cost detection model is obtained; in the same way, a computer model is trained based on the available wastewater component content information until the model converges, and the second cost detection model is obtained.

[0065] Furthermore, the first cost detection model and the second cost detection model obtained by training based on historical sewage treatment data respectively perform intelligent analysis on the first sewage to be treated. That is, firstly, the first sewage component information is input into the first cost detection model, and the model intelligently outputs the second detection result; then, the first component content information is input into the second cost detection model, and the model intelligently outputs the third detection result. Finally, the second detection result and the third detection result output by the two models are combined to obtain the first detection result. Among them, the first detection result is the determination result of whether the treatment cost of the first sewage is within the corresponding sewage treatment cost range after intelligent analysis.

[0066] Through training based on historical sewage treatment data, we can obtain the first cost detection model and the second cost detection model that can intelligently analyze the components and content of each component in sewage, and then estimate the cleaning cost of the first sewage to be cleaned. Finally, we combine the first sewage component and content detection costs to comprehensively obtain the total cost of the entire sewage treatment. Through the highly personalized cost detection model, we have achieved the technical effect of intelligently detecting sewage treatment costs and improving the accuracy and reliability of cost detection results.

[0067] Furthermore, step S326 of the embodiment of the present application further includes:

[0068] Step S3261: obtaining a predetermined balance threshold;

[0069] Step S3262: Obtaining a weight ratio based on the predetermined balance threshold;

[0070] Step S3263: Perform weighted calculation on the second detection result and the third detection result according to the weight ratio to obtain the first detection result.

[0071] Specifically, the predetermined balance threshold is set and determined in advance by the sewage utilization system based on the recyclable clean fracturing fluid system after comprehensively analyzing the technical difficulties of sewage treatment process. The weight coefficients of the first sewage component and the treatment cost of each component are obtained through the predetermined balance threshold. Finally, the second detection result and the third detection result are weighted by the weight ratio to obtain the first detection result. By presetting the balance threshold based on actual sewage treatment, the sewage treatment cost detection result is closer to reality, achieving the technical effect of improving the accuracy and reliability of the first detection result.

[0072] Furthermore, the embodiment of the present application further includes step S800:

[0073] Step S810: performing component analysis on the second sewage component information to obtain a first analysis result;

[0074] Step S820: determining a first processing sequence according to the first analysis result;

[0075] Step S830: Obtain a second processing solution according to the first processing sequence and the first processing solution.

[0076] Specifically, based on the first sewage component information obtained after the standard test, that is, the second sewage component information, a component analysis is performed to obtain the corresponding first analysis result. Among them, the first analysis result includes a detailed treatment analysis of each component in the first sewage. Further, based on the first analysis result, the order of the components to be treated in the treatment of the first sewage is determined, that is, the first treatment sequence. Finally, the first treatment sequence is combined with the first treatment scheme to obtain the second treatment scheme. By further analyzing the component information in the sewage and combining the key points of each component treatment, the first treatment scheme intelligently generated by the sewage treatment scheme matching model is adaptively adjusted to obtain the second treatment scheme, thereby improving the adaptability of the treatment scheme to the actual sewage situation and achieving the technical effect of improving the rationality of the sewage treatment scheme.

[0077] Furthermore, step S810 of the embodiment of the present application further includes:

[0078] Step S811: constructing a predetermined component group database, wherein the predetermined component group database includes multiple groups of predetermined components, and there is a constraint relationship between each group of predetermined components;

[0079] Step S812: searching the second sewage component information in the predetermined component group database to determine whether the second sewage component information exists in a component group in the predetermined component group database;

[0080] Step S813: If the second sewage component information exists in a component group in the predetermined component group database, determine a first processing sequence according to a corresponding processing sequence in the predetermined component group database.

[0081] Specifically, first, based on the actual sewage treatment process, a predetermined component group database is constructed. The predetermined component group database includes multiple groups of predetermined components in the sewage, and there is a constraint relationship between the cleaning treatment of each group of predetermined components. Based on the second sewage component information, a traversal search is performed in the predetermined component group database, and based on the search results, it is determined whether the second sewage component information exists in the component group in the predetermined component group database, that is, whether there are components in the second sewage components that will constrain each other during cleaning treatment. When the second sewage component information exists in the component group in the predetermined component group database, the first sewage treatment order is adjusted directly according to the corresponding processing order in the predetermined component group database, and then the first processing order is determined. The technical effect of intelligently adjusting the sewage treatment order based on the predetermined component group database is achieved.

[0082] Further, as attached Figure 4 As shown, step S500 of the embodiment of the present application also includes:

[0083] Step S510: constructing the sewage treatment scheme matching model through an autoencoder;

[0084] Step S520: inputting the second sewage component information and the second component content information into the sewage treatment scheme matching model;

[0085] Step S530: Obtain output information of the sewage treatment scheme matching model, wherein the output information includes the first treatment scheme.

[0086] Specifically, the sewage treatment scheme matching model is constructed by encoding with an autoencoder. The autoencoder can self-learn the second sewage component information and the second component content information, and then intelligently analyze and obtain corresponding output information. The output information includes the cleaning treatment scheme of the first sewage, that is, the first treatment scheme. Through the sewage treatment scheme matching model, a sewage cleaning treatment scheme design with a high degree of individualization is achieved, which improves the efficiency of sewage treatment and the rationality of the treatment scheme.

[0087] In summary, the sewage utilization method based on a recyclable clean fracturing fluid system provided in the embodiments of the present application has the following technical effects:

[0088] 1. Obtain the water quality standard of the clean fracturing fluid system; obtain the first sewage information; obtain the first pretreatment instruction; perform standard testing on the first sewage according to the first pretreatment instruction to obtain the second sewage component information and the second component content information of the first sewage information; input the second sewage component information and the second component content information into the sewage treatment scheme matching model to obtain the first treatment scheme; treat the first sewage according to the first treatment scheme to obtain the first purified water; mix the first purified water with the recyclable clean fracturing fluid thickener. Through intelligent sewage pretreatment to build a corresponding computer model, so as to intelligently formulate a targeted sewage treatment plan, realize the technical goal of intelligent treatment and recycling of sewage in the fracturing fluid system, and achieve the technical effect of improving the sewage treatment efficiency and treatment quality of the fracturing fluid system, and then intelligently mixing and recycling.

[0089] 2. By simply testing the sewage before pretreatment, the cost of cleaning the corresponding sewage is estimated. Only when the cost of sewage treatment does not exceed the relevant sewage treatment cost standard, the system will issue a pretreatment instruction and then clean the sewage. This avoids the problem of sewage treatment being difficult and costly, and blindly treating but wasting manpower, material resources and other resources, and achieves the technical effect of improving the intelligence and reliability of sewage treatment.

[0090] 3. Through a highly personalized cost detection model, the technical effect of intelligently detecting sewage treatment costs and improving the accuracy and reliability of cost detection results is achieved.

[0091] 4.
