[0039] Oil shale resources are abundant in reserves. Facing the current shortage of petroleum resources and rising oil prices, the development of oil shale resources has gradually become a hot topic. Oil shale mining technologies are divided into in-situ mining and ex-situ mining. In-situ mining has become the focus and mainstream of oil shale development and utilization due to its advantages such as low cost, high quality, and less environmental disturbance.
[0040] Currently, the carbon emission determination methods for resource development mostly target coal, oil, and natural gas mining, lacking a carbon emission determination method for oil shale. Moreover, the in-situ oil shale mining process is different from the coal or oil and natural gas mining processes. In-situ oil shale mining first drills wells on the surface, hydraulically fractures the oil shale layer through the wells to generate oil and gas communication channels, and then heats it to decompose organic matter and carbonate minerals in it to produce CO 2 、CO、CH 4 、H 2 and other gases, and a large amount of water resources, electric power resources, etc. will be consumed during the process. During the oil shale mining cycle, the carbon emissions generated in different links are all different. Based on the existing carbon emission determination methods, it is impossible to accurately and comprehensively determine the carbon emissions of the entire oil shale mining process, and thus it is impossible to accurately formulate carbon emission reduction measures for in-situ oil shale mining.
[0041] In view of the above problems existing in the existing methods and the specific reasons for these problems, the present application contemplates introducing a method and device for determining carbon emissions based on in-situ oil shale mining, which can clarify the carbon emission levels of each mining link, accurately and comprehensively determine the carbon emissions throughout the process of oil shale mining, and provide a reliable reference basis for the evaluation of the environmental impact of the carbon emission effect of in-situ oil shale mining and the formulation and implementation of carbon emission reduction measures.
[0042] Based on the above idea, this specification proposes a method for determining carbon emissions based on in-situ oil shale mining. First, determine the types of energy consumption corresponding to each mining link in in-situ oil shale mining. Then, based on the types of energy consumption corresponding to each mining link, determine the carbon emissions of each mining link. Finally, obtain the greenhouse gas emissions during in-situ oil shale mining, and based on the carbon emissions of each mining link and the greenhouse gas emissions, determine the total carbon emissions of in-situ oil shale mining.

Although this specification provides method operation steps or device structures as shown in the following embodiments or drawings, based on routine or non-creative labor, more or fewer operation steps or module units may be included in the method or device. In steps or structures where there is no necessary causal relationship logically, the execution order of these steps or the module structure of the device is not limited to the execution order or module structure shown in the embodiments or drawings of this specification. When the method or module structure is applied to an actual device, server or terminal product, it can be executed sequentially or in parallel according to the method or module structure shown in the embodiments or drawings (for example, in an environment of parallel processors or multi-threaded processing, even including an environment of distributed processing and server clusters). For specific implementation, refer to Figure 1 As shown, the method may include the following.

[0140] By determining the carbon emissions (E 钻井 , E 水力压裂 , E 注蒸汽加热 , E 油气收集 , E 运输 ) of each mining link in the in-situ oil shale mining process, the carbon emission levels of each mining link can be clarified. At the same time, it lays a foundation for accurately determining the total carbon emissions of the entire in-situ oil shale mining process subsequently.
[0141] S103: Obtain the greenhouse gas emissions during in-situ oil shale mining, and determine the total carbon emissions of in-situ oil shale mining based on the carbon emissions of each mining link and the greenhouse gas emissions.
[0142] In some embodiments, the above-mentioned obtaining the greenhouse gas emissions during in-situ oil shale mining may specifically include:
[0143] Obtain the mining volume of oil shale, the carbon emission factor of greenhouse gases in oil shale mining, and the density of greenhouse gases;
[0144] Using the pre - constructed greenhouse gas emission determination equation to process the extraction volume of oil shale, the carbon emission factor of greenhouse gases in oil shale extraction, and the density of greenhouse gases, the greenhouse gas emissions during in - situ extraction of oil shale are obtained. The greenhouse gas emission determination equation is established in advance using the sample data corresponding to the extraction volume of oil shale, the carbon emission factor of greenhouse gases in oil shale extraction, and the density of greenhouse gases.
[0145] In some embodiments, the above - mentioned pre - constructed greenhouse gas emission determination equation may include:
[0146]
[0147] where E 逸散 is the sample data of greenhouse gas emissions during in - situ extraction of oil shale; is the sample data of the global warming potential of methane gas; M 油页岩 is the sample data of the extraction volume of oil shale; is the sample data of the carbon emission factor of methane gas; is the sample data of the density of methane gas; is the sample data of the carbon emission factor of carbon dioxide gas; is the sample data of the density of carbon dioxide gas.
[0148] In some embodiments, the greenhouse gas emission determination equation established in advance using the sample data corresponding to the extraction volume of oil shale, the carbon emission factor of greenhouse gases in oil shale extraction, and the density of greenhouse gases can be used in actual applications to process the extraction volume of oil shale, the carbon emission factor of greenhouse gases in oil shale extraction, and the density of greenhouse gases, so as to accurately and quickly obtain the greenhouse gas emissions during in - situ extraction of oil shale.
[0149] In some embodiments, the emissions during in - situ extraction of oil shale are different from the gas emissions during coal mining and also different from the emissions in industries such as petroleum refining. The emissions during in - situ extraction of oil shale can include not only methane but also carbon dioxide. It is necessary to convert the emissions of both greenhouse gases into carbon dioxide equivalents for comparative calculation, and they account for a relatively large proportion in the overall emissions during in - situ extraction. Therefore, when calculating the total carbon emissions during in - situ extraction of oil shale, the greenhouse gas emissions during in - situ extraction of oil shale need to be taken into account to improve the accuracy of calculating the total carbon emissions during in - situ extraction of oil shale.
[0150] In some embodiments, to determine the total carbon emissions during in - situ extraction of oil shale based on the carbon emissions and greenhouse gas emissions in each extraction link, in specific implementation, it may include:
[0151] Input the carbon emissions and greenhouse gas emissions in each mining link into the pre-constructed oil shale carbon emissions determination equation, and output the total carbon emissions of in-situ oil shale mining. The oil shale carbon emissions determination equation is pre-established using the sample data corresponding to the carbon emissions and greenhouse gas emissions in each mining link.
[0152] In some embodiments, the pre-constructed oil shale carbon emissions determination equation described above may include:
[0153] E 总 = E 钻井 + E 水力压裂 + E 注蒸汽加热 + E 油气收集 + E 运输 + E 逸散
[0154] Wherein, E 总 is the sample data of the total carbon emissions of in-situ oil shale mining; E 钻井 is the sample data of the carbon emissions in the drilling link; E 水力压裂 is the sample data of the carbon emissions in the hydraulic fracturing link; E 注蒸汽加热 is the sample data of the carbon emissions in the steam injection heating link; E 油气收集 is the sample data of the carbon emissions in the oil and gas collection, processing and emission link; E 运输 is the sample data of the carbon emissions in the transportation link; E 逸散 is the sample data of the greenhouse gas emissions in in-situ oil shale mining.
[0155] In some embodiments, the pre-constructed oil shale carbon emissions determination equation described above may also be referred to as a pre-trained oil shale carbon emissions determination model. The oil shale carbon emissions determination model can be trained using the sample data corresponding to the carbon emissions and greenhouse gas emissions in each mining link. In actual application, based on the oil shale carbon emissions determination model, the total carbon emissions of in-situ oil shale mining (i.e., the carbon emissions throughout the in-situ oil shale mining process) can be accurately and quickly determined.
[0156] By determining the total carbon emissions of in-situ oil shale mining, it can provide a reliable reference basis for the subsequent evaluation of the environmental impact of the carbon emission effect of in-situ oil shale mining and the formulation and implementation of carbon emission reduction measures.
[0157] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0160] Before the specific implementation, first, clarify multiple mining links in the in-situ oil shale mining process, such as: drilling link, hydraulic fracturing link, steam injection heating link, oil and gas collection, treatment and emission link (or simply referred to as the oil and gas collection link), and transportation to the refinery link (or simply referred to as the transportation link). Then, determine multiple carbon emission sources, such as: fuel combustion (such as diesel, raw coal, etc.), fugitive emissions, process emissions, grid electricity, and water resources. Then, according to multiple carbon emission sources, obtain the carbon emission factor sample data corresponding to multiple carbon emission sources from the carbon emission factor database, obtain the energy consumption sample data of each mining link from the energy consumption database, and based on the carbon emission factor sample data and the energy consumption sample data, determine the carbon emission sample data corresponding to each mining link. Finally, obtain the greenhouse gas fugitive emission sample data in the in-situ oil shale mining, and train the oil shale carbon emission determination model according to the greenhouse gas fugitive emission sample data in the in-situ oil shale mining and the carbon emission sample data corresponding to each mining link. During the specific implementation, the carbon emissions and greenhouse gas fugitive emissions of each mining link can be processed based on the oil shale carbon emission determination model to obtain the total carbon emissions of the in-situ oil shale mining.
[0161] Through the above method, the accounting of the carbon emissions in the whole process of in-situ oil shale mining can be realized to the greatest extent, the carbon emission levels of each mining link can be clarified, and the accuracy and efficiency of the accounting are improved.
[0162] In a specific scenario example, assume that the in-situ mined oil shale in a certain place is 300,000 tons, the oil recovery rate is 2.57%, about 11.67 million tons of oil shale need to be mined, and the produced gas is about 3.7971×10 8 m 3 ,CH 4 and CO 2 The proportions of 4 and CO 2The densities are 0.67×10 -3 t / m 3 、1.816×10 -3 t / m 3 . 200 tons of diesel, 9000 MWh / t of grid electricity and 2.62 million tons of water resources are consumed in the drilling process. 1500 tons of raw coal, 50 tons of diesel, 6×10 4 MWh / t of grid electricity and 15 million tons of water resources are consumed in the hydraulic fracturing process. 2500 tons of raw coal, 50 tons of diesel, 18×10 4 MWh / t of grid electricity and 15 million tons of water resources are consumed in the steam injection heating process. 3×10 4 MWh / t of grid electricity and 0.3 million tons of water resources are consumed in the oil and gas collection process. 200 tons of diesel, 2.1×10 4 MWh / t of grid electricity and 0.5 million tons of water resources are consumed in the transportation process; The carbon emission factors of different energy sources are determined as shown in Table 1:

[0167]
[0168] Refer to Figure 2 shown Figure 2 is a schematic flow chart established based on the carbon emission accounting model for in-situ oil shale mining. As Figure 2 shown: The carbon emission accounting boundary can be determined first, such as: drilling, hydraulic fracturing, steam injection heating, oil and gas collection, treatment and emission links, transportation, etc.; Then, determine the carbon emission sources of each mining link, such as: fuel combustion, fugitive emissions, process emissions, grid electricity, water resources; Then, determine the carbon emission factors of the mining link, such as: a 原煤 、a 柴油 、a 电力 、a 水 (or referred to as a 水资源 )、a CH4逸散 、a CO2逸散 ; Finally, based on the carbon emission factors of the mining link and the energy consumption of the mining link, the carbon emissions of each mining link can be determined, and then based on the carbon emissions of each mining link, according to E 总 =E 钻井 +E 水力压裂 +E 注蒸汽加热 +E 油气收集 +E运输 +E 逸散 Establish a carbon emission accounting model. It is possible to collect basic data again, conduct an example verification on the carbon emission accounting model, and finally obtain a carbon emission accounting model for in-situ oil shale mining (that is, the pre-constructed oil shale carbon emission determination equation or the pre-trained oil shale carbon emission determination model in the above embodiments).

[0182] It should be noted that the units, devices, or modules described in the above embodiments may be specifically implemented by computer chips or entities, or by products with certain functions. For the convenience of description, the above devices are described by dividing them into various modules according to functions. Of course, when implementing this specification, the functions of each module may be implemented in the same or multiple software and / or hardware, or the modules implementing the same function may be realized by a combination of multiple sub-modules or sub-units, etc. The device embodiments described above are only illustrative. For example, the division of the units is only a logical function division, and there may be other division methods in actual implementation. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Another point is that the displayed or discussed couplings or direct couplings or communication connections between each other may be through some interfaces. The indirect couplings or communication connections of the devices or units may be in electrical, mechanical, or other forms.
[0183] As can be seen from the above, based on a carbon emission determination device for in-situ oil shale mining provided by an embodiment of this specification, it is possible to track the life cycle of the in-situ oil shale mining process, clarify the carbon emission levels of each mining link, maximize the accounting of the total carbon emissions of the entire in-situ oil shale mining process, and improve the accuracy of the accounting.
[0184] An embodiment of this specification also provides an electronic device for a method of determining carbon emissions based on in-situ oil shale mining, including a processor and a memory for storing instructions executable by the processor. When specifically implemented, the processor may execute the following steps according to the instructions: determine the types of energy consumption corresponding to each mining link in in-situ oil shale mining; determine the carbon emissions of each mining link according to the types of energy consumption corresponding to each mining link; obtain the greenhouse gas emissions in in-situ oil shale mining, and determine the total carbon emissions of in-situ oil shale mining according to the carbon emissions of each mining link and the greenhouse gas emissions.

Among them, the electronic device includes a network communication port 401, a processor 402, and a memory 403. The above structures are connected by internal cables so that each structure can perform specific data interactions.
[0186] Among them, the network communication port 401 can specifically be used to determine the types of energy consumption corresponding to each mining link in in-situ oil shale mining;
[0187] The processor 402 can specifically be used to determine the carbon emissions of each mining link according to the types of energy consumption corresponding to each mining link; obtain the greenhouse gas emissions in in-situ oil shale mining, and determine the total carbon emissions of in-situ oil shale mining according to the carbon emissions of each mining link and the greenhouse gas emissions.
[0188] The memory 403 can specifically be used to store the corresponding instruction programs.
[0189] In this embodiment, the network communication port 401 can be bound to different communication protocols, so as to send or receive different data virtual ports. For example, the network communication port can be a port responsible for web data communication, can also be a port responsible for FTP data communication, and can also be a port responsible for mail data communication. In addition, the network communication port can also be a physical communication interface or communication chip. For example, it can be a wireless mobile network communication chip, such as GSM, CDMA, etc.; it can also be a Wifi chip; it can also be a Bluetooth chip.
[0190] In this embodiment, the processor 402 may be implemented in any suitable manner. For example, the processor may take the form of, for example, a microprocessor or a processor, a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller, etc. This specification does not make any limitations.
[0191] In this embodiment, the memory 403 may include multiple levels. In a digital system, anything that can store binary data can be a memory; in an integrated circuit, a circuit with a storage function without a physical form is also called a memory, such as RAM, FIFO, etc.; in a system, a storage device with a physical form is also called a memory, such as a memory stick, a TF card, etc.
[0192] The embodiment of this specification also provides a computer storage medium for a method of determining carbon emissions based on in-situ oil shale mining. The computer storage medium stores computer program instructions, which when executed, implement: determining the types of energy consumption corresponding to each mining link in in-situ oil shale mining; determining the carbon emissions of each mining link according to the types of energy consumption corresponding to each mining link; obtaining the greenhouse gas emissions in in-situ oil shale mining, and determining the total carbon emissions of in-situ oil shale mining according to the carbon emissions of each mining link and the greenhouse gas emissions.

The memory may be used to store computer program instructions. The network communication unit may be set according to the standards specified by the communication protocol and is used as an interface for network connection communication.
[0194] Although this specification provides method operation steps as described in the embodiments or flowcharts, more or fewer operation steps may be included based on conventional or non-creative means. The order of steps listed in the embodiments is only one way among the execution orders of numerous steps and does not represent the only execution order. When the actual device or client product is executed, it can be executed in the order of the method shown in the embodiments or the drawings or in parallel (for example, in an environment of parallel processors or multi-threaded processing, or even in a distributed data processing environment). The terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, product or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, product or device. Without further limitation, there is no exclusion of additional identical or equivalent elements in the process, method, product or device comprising the said elements. The terms such as "first", "second" are used to denote names and do not denote any particular order.
[0195] As is also known to those skilled in the art, in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to logically program the method steps so that the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. to achieve the same function. Therefore, such a controller can be regarded as a hardware component, and the devices included therein for implementing various functions can also be regarded as the structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or the structures within the hardware component.
[0196] This specification can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, classes, etc. that perform specific tasks or implement specific abstract data types. This specification can also be practiced in a distributed computing environment where tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.
[0197] As can be seen from the description of the above embodiments, those skilled in the art can clearly understand that this specification can be implemented by means of software plus a necessary general hardware platform. Based on such an understanding, the technical solution of this specification can essentially be embodied in the form of a software product, which can be stored in a storage medium, such as ROM / RAM, magnetic disk, optical disk, etc., and includes several instructions for causing a computer device (which can be a personal computer, mobile terminal, server, or network device, etc.) to execute the methods described in each embodiment or some parts of the embodiments of this specification.
[0198] The embodiments in this specification are described in a progressive manner. For the same or similar parts between the embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments. This specification can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multi-processor systems, microprocessor-based systems, set-top boxes, programmable electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, and so on.
[0199] Although this specification is depicted through embodiments, those of ordinary skill in the art know that this specification has many variations without departing from the spirit of this specification. It is hoped that the appended claims will cover these variations without departing from the spirit of this specification.
