It should be noted that in the flowchart in the accompanying drawings, the steps shown therein can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0028] The following is an introduction to the method for constructing a natural gas development corridor in a coal mining area according to an embodiment of the present invention.

[0029] Figure 1 is a flow chart of a method for constructing a natural gas development corridor in a coal mining area according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0030] Step S101, obtaining first parameter information of natural gas and second parameter information of coal in a coal mining area, wherein the first parameter information is used to characterize the geological characteristics of the natural gas reservoir, and the second parameter information is used to characterize the geological characteristics of the coal reservoir.

[0031] In the technical solution provided in the above step S101 of the present invention, geological exploration technology can be used to obtain the first parameter information of the natural gas and the second parameter information of the coal in the coal mining area.

[0032] Optionally, the first parameter information of natural gas can be parameter information in the natural gas field, such as natural gas overlying strata structure information, natural gas reservoir depth information, reservoir structural characteristic information, reservoir lithology and physical property characteristic information, reservoir physical property lower limit information, reservoir classification information, effective sand body distribution information of each sublayer, favorable area distribution information, natural gas reserve distribution information, etc.

[0033] Optionally, the second parameter information of coal can be parameter information in the coal field, such as coal seam resource condition information, mineable coal seam overburden structure information, ground stress distribution characteristic information, coal seam burial depth information, hydrogeological condition information, engineering geological condition information, resource reserve information, etc.

[0034] It should be noted that this is only a preferred implementation method for obtaining the first parameter information of natural gas and the second parameter information of coal in the coal mining area, and does not specifically limit the process and method of obtaining the first parameter information of natural gas and the second parameter information of coal in the coal mining area.

[0035] Step S102, based on the first parameter information and the second parameter information, determine the development mode, size information and location information of the natural gas development corridor to be constructed, wherein the development mode is used to characterize the development sequence of natural gas and coal.

[0036] In the technical solution provided in the above step S102 of the present invention, after obtaining the first parameter information and the second parameter information, the development mode, size information and location information of the natural gas development corridor to be constructed can be determined according to the first parameter information and the second parameter information. Among them, the development mode is used to characterize that different development modes are implemented in different areas within the coal mining area. The size information of the natural gas development corridor can be referred to as the corridor size. The location information of the natural gas development corridor can be referred to as the corridor location.

[0037] For example, after obtaining first parameter information such as natural gas overlying strata structure information, natural gas reservoir depth information, reservoir structural characteristics information, and second parameter information such as coal seam resource condition information and mineable coal seam overlying strata structure information, the development sequence of natural gas and coal in the natural gas development corridor to be constructed, the corridor size and corridor location can be determined within the coal mining area to achieve the purpose of constructing a suitable natural gas development corridor.

[0038] It should be noted that this is only a preferred implementation method for determining the development mode, size information and location information of the natural gas development corridor to be constructed. The process and method for determining the development mode, size information and location information of the natural gas development corridor to be constructed are not specifically limited. As long as the process and method for determining the development mode, size information and location information of the natural gas development corridor to be constructed are based on the first parameter information and the second parameter information, they are within the protection scope of the present invention and will not be listed here.

[0039] Step S103, in response to the development mode, constructing a natural gas development corridor based on the size information and the location information.

[0040] In the technical solution provided in the above step S103 of the present invention, in response to the obtained development mode, a natural gas development corridor can be constructed according to the size information and the location information. The natural gas development corridor can be referred to as a development corridor. For example, after obtaining the development sequence of natural gas and coal, a natural gas development corridor can be constructed according to the corridor size and the corridor location.

[0041] It can be understood that this is only a preferred implementation method for constructing a natural gas development corridor, and the process and method of constructing a natural gas development corridor are not specifically limited. As long as it is under a certain development mode, the process and method of constructing a natural gas development corridor based on size information and location information are within the scope of protection of the present invention and will not be repeated here.

[0042] In the above steps S101 to S103 of the present invention, first parameter information of natural gas and second parameter information of coal in the coal mining area are obtained, wherein the first parameter information is used to characterize the geological characteristics of the natural gas reservoir, and the second parameter information is used to characterize the geological characteristics of the coal reservoir; based on the first parameter information and the second parameter information, the development mode, size information and location information of the natural gas development corridor to be constructed are determined, wherein the development mode is used to characterize the development sequence of natural gas and coal; in response to the development mode, a natural gas development corridor is constructed based on the size information and the location information. That is to say, the first parameter information of natural gas and the second parameter information of coal can be obtained first, and then the development mode, size information and location information of the natural gas development corridor to be constructed can be determined based on the first parameter information and the second parameter information obtained above. Finally, under the development mode determined at this time, the natural gas development corridor can be constructed according to the size information and the location information. Considering that after obtaining the first parameter information of natural gas and the second parameter information of coal, the development mode, size information and location information of the natural gas development corridor to be constructed can be determined according to the first parameter information and the second parameter information, and then under this development mode, the purpose of constructing the natural gas development corridor is achieved according to the size information and the location information obtained above. After the natural gas development corridor is constructed, based on the natural gas development corridor, the technical problem of not being able to effectively develop natural gas and coal in the overlapping resource areas of coal and natural gas is solved, and the technical effect of effectively developing natural gas and coal in the overlapping resource areas of coal and natural gas is achieved.

[0043] The above method of this embodiment is further introduced below.

[0044] As an optional implementation method, based on the first parameter information and the second parameter information, a development mode of a natural gas development corridor to be constructed is determined, including: based on the first parameter information and the second parameter information, a target dividing line is determined; based on the target dividing line, a first area and a second area are determined in the coal mining area; a first development mode of the development mode is executed in the first area, and a second development mode of the development mode is executed in the second area, wherein the first development mode is used to characterize the simultaneous development of natural gas and coal, and the second development mode is used to characterize the development of natural gas first and then the development of coal.

[0045] In this embodiment, the target dividing line can be determined based on the first parameter information and the second parameter information, and then based on the target dividing line obtained above, the first area and the second area are determined within the coal mining area, the first development mode of the development mode is executed in the first area, and the second development mode of the development mode is executed in the second area.

[0046] Optionally, the target demarcation line can be called a time-space avoidance limit, or a limit boundary. The first area can be called a coal early development block. The second area can be called a coal long-term follow-up block. The first development mode can be called a coal-gas coordinated space avoidance development mode, or simply referred to as a coal-gas coordinated space avoidance. The second development mode can be called a gas-first-then-coal time avoidance development mode, or simply referred to as a gas-first-then-coal time avoidance.

[0047] For example, based on the parameter information of natural gas and coal, the time and space avoidance boundaries are determined, and different areas are divided based on the time and space avoidance boundaries. Within different boundary ranges, time avoidance of gas first and coal later and coordinated spatial avoidance of coal and gas are carried out respectively, so as to achieve the purpose of effectively developing natural gas and coal. That is to say, by using the time and space avoidance boundaries, the coal mining area is divided into early coal development blocks and long-term coal succession blocks, and the development mode of coordinated spatial avoidance of coal and gas is implemented in the early coal development blocks, and the development mode of time avoidance of gas first and coal later is implemented in the long-term coal succession blocks.

[0048] As an optional implementation method, based on the first parameter information and the second parameter information, the size information of the natural gas development corridor to be constructed is determined, including: obtaining the stratigraphic structure information, mining information, and parameter information of the deployed wells in the coal mining area; based on the stratigraphic structure information, mining information, parameter information of the wells, the first parameter information and the second parameter information, the size information is determined.

[0049] In this embodiment, stratigraphic structure information, mining information, and parameter information of deployed wells in the coal mining area can be obtained, and then the purpose of determining the size information is achieved based on the stratigraphic structure information, mining information, well parameter information, first parameter information, and second parameter information obtained above.

[0050] Optionally, the dimension information is used to characterize the relevant dimensions of the natural gas development corridor, such as the corridor ground width, corridor avoidance distance, corridor centering distance and different coal seam mining widths, etc. The dimension information is only illustrated here, and the dimension information is not specifically limited.

[0051] Optionally, the stratigraphic structure information can be called burial depth and stratigraphic structure information, or simply burial depth and stratigraphic structure, for example, the depth of coal and natural gas resources with development value from the surface, the distribution of overlying rock strata of coal and natural gas, lithology, strength, hydrological characteristics, geological structure and other parameters.

[0052] Optionally, mining information is used to characterize the mining situation in the process of building a natural gas development corridor, which can be called development and mining information, such as industrial square and wellhead location selection, main development tunnel planning, mining layout, production scheduling of panels and working faces, permanent coal pillars, etc. Among them, the permanent coal pillar can be called a permanent protective coal pillar.

[0053] Optionally, the parameter information of the well may include well type, well pattern and well spacing, for example, the selection and combination of vertical wells, directional wells and horizontal wells, well pattern type, optimization information of well pattern density, length of horizontal section of horizontal well, etc.

[0054] As an optional implementation method, based on the first parameter information and the second parameter information, the location information of the natural gas development corridor to be constructed is determined, including: obtaining industrial equipment distribution information and planning information within the coal mining area; and determining the location information based on the industrial equipment distribution information, planning information, the first parameter information and the second parameter information.

[0055] In this embodiment, industrial equipment distribution information and planning information can be obtained in the coal mining area. According to the industrial equipment distribution information, planning information, first parameter information and second parameter information obtained above, the purpose of determining the location information can be achieved.

[0056] Alternatively, the industrial equipment distribution information may be referred to as the industrial facility distribution information, or simply referred to as the industrial facility distribution, wherein in the process of natural gas extraction, the industrial facility distribution mainly includes: natural gas wells, natural gas transmission pipelines, natural gas station facilities and other necessary facilities. In the process of coal extraction, the industrial facility distribution mainly includes: industrial squares, roads, railways, power transmission lines and other necessary facilities.

[0057] Optionally, planning information can be used to characterize the development planning information of natural gas and coal, which can be called the development planning information of both parties, or simply the development planning of both parties. In the process of natural gas exploitation, the development planning of both parties mainly includes: key development areas of natural gas, selection of well types and well networks, design of wellbore trajectories, optimization of well spacing, pipeline layout, distribution of new wells and their number, layout of new pipelines, disposal of abandoned facilities and annual plans, etc. In the process of coal exploitation, the development planning of both parties mainly includes: timing of mine development and construction, planning of ground facilities, selection of early development blocks, selection of first mining coal seams, selection of first mining working faces, design of mining layout and scheduling of mining and excavation succession, etc.

[0058] As an optional implementation method, in response to a development mode, a natural gas development corridor is constructed based on size information and location information, including: in response to the development mode, based on size information and location information, multiple construction strategies for the natural gas development corridor to be constructed are determined; based on evaluation information of the natural gas development corridor to be constructed, multiple construction strategies are evaluated to obtain multiple evaluation values; the multiple evaluation values ​​are determined as multiple priorities; from the multiple priorities, a target priority is selected, and a target construction strategy corresponding to the target priority is determined; and the target construction strategy is executed to obtain the natural gas development corridor.

[0059] In this embodiment, in the obtained development mode, multiple construction strategies for the natural gas development corridor to be constructed can be determined first based on the size information and the location information, and then the multiple construction strategies can be evaluated based on the evaluation information of the natural gas development corridor to be constructed to obtain multiple evaluation values, and the multiple evaluation values ​​are determined as multiple priorities. From the multiple priorities obtained above, the target priority is selected, and the target construction strategy corresponding to the target priority is determined. Finally, the target construction strategy can be executed to obtain the natural gas development corridor.

[0060] Optionally, multiple construction strategies can be used to characterize construction schemes of multiple natural gas development corridors. The evaluation information can be evaluation parameters for constructing natural gas development corridors, such as gas well cost and life, working face mining sequence, and corridor safety service time. The target priority can be a preset priority, which can be the highest priority among multiple priorities.

[0061] For example, the priority setting of the natural gas development corridor is based on the planning of multiple natural gas development corridor plans. The parameters that need to be considered include at least the cost and life of the gas well, the sequence of working face mining, and the safe service time of the corridor. Furthermore, multiple priorities can be obtained from the above process. The highest priority is selected from the multiple priorities, and the construction plan of the natural gas development corridor corresponding to the highest priority is used to determine the final coal-gas collaborative development corridor plan, and the site is prepared accordingly.

[0062] As an optional implementation method, the natural gas development corridor includes: a target development corridor and a transportation channel between the target development corridors, wherein the target development corridor is used to lay out natural gas wells, natural gas stations and natural gas pipelines, and the transportation channel between the target development corridors is used to lay out natural gas pipelines.

[0063] In this embodiment, the natural gas development corridor includes: a target development corridor and a transmission channel between the target development corridors, wherein the target development corridor can be called a natural gas collaborative development corridor, and the transmission channel between the target development corridors can be called a transmission channel between natural gas collaborative development corridors, or a transmission channel between natural gas collaborative corridors.

[0064] For example, the corridors of the early coal development blocks and the long-term coal succession blocks are both composed of natural gas coordinated development corridors and transmission channels between natural gas coordinated corridors. The natural gas coordinated development corridors are used to lay out natural gas wells, natural gas stations and natural gas pipelines, and the transmission channels between natural gas coordinated corridors are used to lay out natural gas pipelines.

[0065] As an optional implementation mode, the method also includes: deploying coal mine tunnels in the coal mining area, and deploying target development corridors and transportation channels between target development corridors within a preset range of the coal mine tunnels.

[0066] In this embodiment, a coal mine tunnel is deployed in the coal mining area, and within the preset range of the coal mine tunnel, a target development corridor and a transportation channel between the target development corridors are deployed. The coal mine tunnel can be called a coal mine main tunnel, which is used to transport coal and can connect different parts of the mine so that coal can be smoothly transported from the bottom of the mine to the ground or other places; it is also used to ensure that miners can get sufficient oxygen and a safe working environment when working underground.

[0067] In this embodiment, the first parameter information of natural gas and the second parameter information of coal in the coal mining area are obtained, wherein the first parameter information is used to characterize the geological characteristics of the natural gas reservoir, and the second parameter information is used to characterize the geological characteristics of the coal reservoir; based on the first parameter information and the second parameter information, the development mode, size information and location information of the natural gas development corridor to be constructed are determined, wherein the development mode is used to characterize the development sequence of natural gas and coal; in response to the development mode, the natural gas development corridor is constructed based on the size information and the location information. That is to say, considering that after obtaining the first parameter information of natural gas and the second parameter information of coal, the development mode, size information and location information of the natural gas development corridor to be constructed can be determined according to the first parameter information and the second parameter information, and then under this development mode, according to the size information and location information obtained above, the purpose of constructing the natural gas development corridor is achieved. After the natural gas development corridor is constructed, based on the natural gas development corridor, the technical problem that natural gas and coal cannot be effectively developed in the overlapping area of ​​coal and natural gas resources is solved, and the technical effect that natural gas and coal can be effectively developed in the overlapping area of ​​coal and natural gas resources is achieved.

[0068] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0069] Both natural gas and coal have relatively abundant reserves in specific regions. For example, the total reserves of natural gas and coal account for 29% and 35% of the country respectively. Both coal and natural gas are important energy sources. However, there is resource overlap in these regions, resulting in overlapping mining rights. Due to the different development entities and different processes in development technology, it is difficult to jointly develop the two resources in the overlapping areas, resulting in technical problems such as the inability to effectively develop natural gas and coal in the overlapping areas of coal and natural gas resources.

[0070] In order to solve the above problems, the present invention proposes a method for constructing a natural gas development corridor system in a coal mining area. The method can obtain parameter information of natural gas and parameter information of coal in the coal mining area, and then determine the development mode, corridor size and corridor position of the natural gas development corridor to be constructed according to the parameter information of the two resources obtained above, and then construct a natural gas development corridor according to the development mode, corridor size and corridor position obtained above. After the natural gas development corridor is constructed, based on the natural gas development corridor, the technical problem of being unable to effectively develop natural gas and coal in the overlapping resource areas of coal and natural gas is solved, and the technical effect of effectively developing natural gas and coal in the overlapping resource areas of coal and natural gas is achieved.

The coal mining area refers to the coal and natural gas deposits with large-scale development distributed in different strata within the scope of the mining area.

[0074] For example, parameter information in the natural gas field includes: natural gas overlying strata structure information, natural gas reservoir depth information, reservoir structural characteristic information, reservoir lithology and physical property characteristic information, reservoir physical property lower limit information, reservoir classification information, effective sand body distribution information of each sublayer, favorable area distribution information, natural gas reserve distribution information, etc.

[0075] For example, parameter information in the coal field includes: coal seam resource condition information, mineable coal seam overburden structure information, ground stress distribution characteristic information, coal seam burial depth information, hydrogeological condition information, engineering geological condition information, resource reserve information, etc.

[0082] Optionally, the development mode is defined using time and space avoidance boundaries, and within different boundary ranges, a gas-first-coal-later time avoidance development mode and a coal-gas coordinated space avoidance development mode are respectively implemented.

[0083] Optionally, the spatiotemporal avoidance boundary is within the coal mining area, e.g. Figure 5 The dividing line shown is the coal early development block 16 and the coal future follow-up block 17.

[0084] Alternatively, if Figure 4As shown, the corridors of the coal early development block section 16 and the coal long-term follow-up block section 17 are both composed of the natural gas coordinated development corridor 6 and the transmission channel 12 between the natural gas coordinated corridors, wherein the natural gas coordinated development corridor is used for laying natural gas wells, natural gas stations and natural gas pipelines, and the transmission channel between the natural gas coordinated corridors is used for laying natural gas pipelines.

[0085] Optionally, in the coal pre-development block 16, the natural gas coordinated development corridor 6 and the natural gas coordinated corridor transmission channel 12 are mainly based on space avoidance. Within the coal seam mining width 10 between the corridors, the coal mining face 11 is arranged; the natural gas well, natural gas station, natural gas pipeline 13, etc. are arranged in the natural gas coordinated development corridor 6, and the two resources are developed at the same time. After the later natural gas resource development is completed, the coal resources are recovered from the temporary protection coal pillar 9 left for a short period of time.

[0086] Optionally, within the coal forward connection block section 17, the natural gas coordinated development corridor 6 and the natural gas coordinated corridor transmission channel 12 are mainly based on time avoidance, and the corridor is constructed in a whole-block avoidance manner. After the natural gas development is completed in this section, the coal mining face 11 is directly arranged according to the order of mining succession, so that time avoidance can be reflected.

[0087] Optionally, the natural gas collaborative development corridor 6 and the natural gas collaborative corridor transmission channel 12 should give priority to arranging permanent protective coal pillars 15 within the protection range of the coal mine main tunnel 14 to reduce coal compression.

[0088] Step S203, determining the corridor size.

[0089] In this embodiment, it is necessary to determine the corridor size based on the well type, well network spacing, burial depth and stratum structure, development and mining information, such as the corridor ground width, corridor avoidance distance, corridor centering distance 8 and different coal seam mining width 10.

[0090] Optionally, the corridor avoidance distance is determined by the ground width of the natural gas collaborative development corridor 6 and 1 / 2 of the difference between the natural gas collaborative development corridor protection coal pillar 9. The specific calculation should follow relevant standards and specifications, for example, Figure 4 As shown, the limit boundary 7 is determined by the rock displacement angle.

[0091] Optionally, the well type, well pattern and well spacing include: selection and combination of vertical wells, directional wells and horizontal wells 5, well pattern type, optimization information of well pattern density, length of horizontal section of horizontal wells and the like.

[0092] Optionally, the burial depth and stratigraphic structure include: the depth of coal and natural gas resources with development value from the surface, the distribution of overlying rock strata of coal and natural gas, lithology, strength, hydrological characteristics, geological structure and other parameters.

[0093] Optionally, the development and mining information includes: selection of industrial square and wellhead location, planning of main development tunnels, mining layout, production scheduling of panel areas and working faces, and retention of permanent protective coal pillars 15.

[0094] Step S204, selecting a corridor location.

[0095] In this embodiment, the corridor location can be selected based on the industrial facility distribution information and the development planning information of both parties. For example, the corridor location selection should take into account the high recovery rate of both coal and natural gas resources, minimize mutual impact, cost-effectiveness, and technical feasibility, and more consideration should be given to the industrial facility distribution of the coal party and the natural gas party and the development planning of both parties.

[0096] Optionally, in the process of natural gas mining, the distribution of industrial facilities mainly includes: natural gas wells, natural gas transmission pipelines 13, natural gas station facilities and other necessary facilities. In the process of coal mining, the distribution of industrial facilities mainly includes: industrial squares, roads, railways, power transmission lines and other necessary facilities.

[0097] Optionally, in the process of natural gas extraction, the development planning of both parties mainly includes: key natural gas development areas, well type and well pattern selection, well trajectory design, well spacing optimization, pipeline layout, new well distribution and number, new pipeline layout method, abandoned facility disposal and annual plan, etc. In the process of coal extraction, the development planning of both parties mainly includes: mine development and construction sequence, surface facility planning, early development block selection, first mining coal seam selection, first mining working face selection, mining layout design and mining and excavation connection scheduling, etc.

[0098] Step S205, determine corridor priorities and construct natural gas development corridors.

[0099] In this embodiment, the priority of the corridor is determined based on parameters such as the cost and life of the gas well, the mining sequence of the working face, and the safe service time of the corridor, and a natural gas development corridor is constructed based on the priority.

[0100] For example, the priority setting of the natural gas development corridor is based on the planning of multiple natural gas development corridor plans. The parameters that need to be considered include at least the cost and life of the gas well, the sequence of working face mining, and the safe service time of the corridor. Furthermore, multiple priorities can be obtained from the above process. The highest priority is selected from the multiple priorities, and the construction plan of the natural gas development corridor corresponding to the highest priority is used to determine the final coal-gas collaborative development corridor plan, and the site is prepared accordingly.

[0101] Optionally, the first level of priority is the highest and should be deployed and developed first. Initially, gas wells can be deployed in each corridor to deepen geological understanding and promote rolling development. It should be noted that the corridor priority and resource advantage areas can also be combined to speed up the deployment of wells and avoid the economic risks and ineffective investment caused by the deployment of a large number of gas wells in the corridor as a whole at one time.

[0102] In this embodiment, when constructing a natural gas development corridor in a coal mining area, the spatial-temporal coordination idea of ​​a single mine based on the corridor deployment is: taking into account the safe and efficient recovery of resources by both parties, in accordance with the general principle of early deployment, early development, and early withdrawal of natural gas, giving priority to time avoidance while taking into account space avoidance; the early coal development blocks require coal-gas collaborative synchronous development, and the long-term coal successor blocks require overall avoidance, gas first and coal later, so that all resources of both parties are recovered, the coal mine does not leave permanent coal pillars, does not produce isolated working faces, and the natural gas is centrally arranged to speed up development.

[0103] In this embodiment, the first parameter information of natural gas and the second parameter information of coal in the coal mining area are obtained, wherein the first parameter information is used to characterize the geological characteristics of the natural gas reservoir, and the second parameter information is used to characterize the geological characteristics of the coal reservoir; based on the first parameter information and the second parameter information, the development mode, size information and location information of the natural gas development corridor to be constructed are determined, wherein the development mode is used to characterize the development sequence of natural gas and coal; in response to the development mode, the natural gas development corridor is constructed based on the size information and the location information. That is to say, considering that after obtaining the first parameter information of natural gas and the second parameter information of coal, the development mode, size information and location information of the natural gas development corridor to be constructed can be determined according to the first parameter information and the second parameter information, and then under this development mode, according to the size information and location information obtained above, the purpose of constructing the natural gas development corridor is achieved. After the natural gas development corridor is constructed, based on the natural gas development corridor, the technical problem that natural gas and coal cannot be effectively developed in the overlapping area of ​​coal and natural gas resources is solved, and the technical effect that natural gas and coal can be effectively developed in the overlapping area of ​​coal and natural gas resources is achieved.
