Description
Technical Field
The application relates to the technical field of environmental science and environmental risk of underground water in an oil and gas field exploitation area, in particular to a method and a device for determining comprehensive antifouling performance of underground water.
Background
The groundwater integrated anti-fouling properties may generally include both groundwater intrinsic anti-fouling properties and groundwater specific anti-fouling properties. The inherent antifouling property of the underground water refers to the difficulty of pollutants entering the underground water under certain geological and hydrogeological conditions of an aquifer, and is only related to the geological and hydrogeological conditions of the aquifer and is not related to the properties of the pollutants. Groundwater specific antifouling properties refer to the ability of groundwater to prevent contamination by a certain contaminant or contaminants, taking into account the nature of the contaminant itself and the ability of the contaminant to migrate in the subterranean environment.
The method for determining the comprehensive antifouling performance of the underground water is characterized by mainly selecting corresponding inherent antifouling performance evaluation indexes and different special antifouling performance evaluation indexes in a DRASTIC model, respectively evaluating the inherent antifouling performance and the special antifouling performance of the underground water through the inherent antifouling performance evaluation indexes and the special antifouling performance evaluation indexes corresponding to the DRASTIC model to respectively obtain an inherent antifouling performance evaluation result and a special antifouling performance evaluation result, and then obtaining an underground water comprehensive antifouling performance evaluation result according to the inherent antifouling performance evaluation result and the special antifouling performance evaluation result to determine the comprehensive antifouling performance of the underground water. The inherent antifouling performance evaluation index corresponding to the DRASTIC model in the method comprises the following steps: groundwater depth, net supply, aquifer medium, soil medium, terrain slope, aeration zone medium, and aquifer hydraulic conductivity. The groundwater depth, net recharge, aquifer medium, soil medium, grade of terrain, aeration zone medium, and aquifer hydraulic conductivity may be indicated by letters D, R, A, S, T, I and C, respectively. The special antifouling performance evaluation indexes selected in the method mainly comprise: one or more indexes of pollutant migration and transformation rules, river network density, land utilization types, oil well distribution density and the like. The implementation of the method needs to be established under basic assumption conditions which mainly comprise the following steps: contaminants are present at the surface; pollutants permeate the ground through rainfall; the contaminants migrate with the water. Meanwhile, the evaluation index adopted by the method reflects the risk that the pollutants migrate to the diving aquifer from top to bottom.
The inventor finds that at least the following problems exist in the prior art: crude oil falls to the ground, the well cementation quality is poor, a shaft is corroded, oil-water channeling layers are caused by water injection, oil-water channeling layers are caused by gas injection and the like in the process of exploiting the oil-gas field, and the risk that pollutants migrate to aquifers from bottom to top can be caused. Aiming at the comprehensive antifouling performance of underground water in an oil and gas field exploitation area, the evaluation index adopted in the prior art cannot accurately evaluate the risk of the pollutants migrating to an aquifer from bottom to top, and the evaluation accuracy of the comprehensive antifouling performance of the underground water is possibly lower.

Detailed Description
The embodiment of the application provides a method and a device for determining comprehensive antifouling performance of underground water.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the continuous development of oil field exploitation areas, the antifouling property of underground water in the oil field exploitation areas also changes continuously. The evaluation index and the DRASTIC model adopted in the prior art are static for evaluating the comprehensive antifouling performance of the groundwater and cannot reflect the long-term dynamic risk characteristics of groundwater pollution in an oilfield exploitation area.
FIG. 1 is a flow chart of an embodiment of a method of determining integrated groundwater antifouling performance according to the present application. As shown in FIG. 1, the method for determining the comprehensive anti-pollution performance of the underground water comprises the following steps.
Step S101: acquiring indexes corresponding to the target area; the indicators include: inherent antifouling performance index and special antifouling performance index.
The groundwater integrated anti-fouling properties may include groundwater intrinsic anti-fouling properties and groundwater specific anti-fouling properties. The inherent antifouling performance index can be used for evaluating the inherent antifouling performance of underground water. The special antifouling performance index can be used for evaluating the special antifouling performance of underground water.
The specific antifouling performance indicator may comprise at least one of: oil gas occurrence depth, fracture development degree, oil layer-water containing layer distance, oil well density, water injection or gas injection well density, regional water recovery, mining mode and mining time. The depth of oil and gas development, the extent of fracture development, the reservoir-to-aquifer separation, the production well density, the injection or water injection well density, the zonal water production, the production mode and the production time may be indicated by the letters L, F, M, O, W, E, Q and Y, respectively.
The correspondence between each of the specific antifouling performance indicators and the comprehensive antifouling performance of groundwater may be as follows.
Because groundwater is distributed in layers in the formation, its burial depth is generally inversely proportional to the economics of groundwater recovery and use, and human activities and production typically use diving or shallow confined water, with little recovery and use of deep groundwater. During oil and gas development, reservoir crude oil may contaminate adjacent groundwater through faults, cap layers, or wellbores, etc. However, the greater the oil and gas occurrence depth, the greater the depth of the adjacent underground water polluted by the crude oil in the reservoir, and the smaller the influence of the pollution on human life and production. Therefore, the corresponding relation between the oil gas occurrence depth and the comprehensive anti-fouling performance of the underground water can be as follows: the larger the oil gas occurrence depth is, the better the comprehensive antifouling performance of the underground water is possible to be.
The corresponding relation between the fracture development degree and the comprehensive antifouling property of the underground water can be as follows: the more developed a fracture is trapped in a hydrocarbon reservoir or the less closed a fault is, the higher the risk of reservoir oil entering a communicating subterranean water layer.
The further the distance between the reservoir and the aquifer, the lower the risk of groundwater contamination. Compared with sandstone, mudstone has stronger isolation capability to reservoir crude oil and lower risk of groundwater pollution. The corresponding relation between the oil layer-water containing layer distance and the comprehensive antifouling property of the underground water can be as follows: the closer the reservoir-aquifer distance, the poorer the overall anti-fouling performance of the groundwater may be.
The number of production wells, and injection water or gas injection wells in the target zone may be used to indicate the extent of hydrocarbon production modification to the reservoir trap. The greater the well density, indicating the higher the reservoir acidized fractures and the extent to which the cap is drilled through, the more times the reservoir crude oil material is exchanged. And thus may result in a higher risk of groundwater contamination. The corresponding relationship between the density of the oil production well and the density of the water injection or gas injection well and the comprehensive antifouling property of underground water can be as follows: the greater the production well density, and the injection water or well density, the worse the overall anti-fouling performance of the groundwater may be.
The water collection amount of the target area can be used for expressing the influence degree of human water collection activities such as oil field development water collection, domestic water collection or farmland irrigation water collection on a groundwater system. When the water production is excessive, it may cause groundwater funneling and ground settlement in the target area, thereby causing groundwater contamination. The corresponding relation between the regional water collection amount and the comprehensive antifouling property of the underground water can be as follows: the larger the water collection amount of the region is, the poorer the comprehensive antifouling performance of the underground water is possibly.
The hydrocarbon recovery mode may include: mining modes such as self-injection mining, water injection or gas injection mining, chemical injection mining and the like; the three production modes can be respectively called primary oil recovery, secondary oil recovery and tertiary oil recovery. The primary oil recovery is to utilize the original formation pressure to realize the self-injection of crude oil, so that the crude oil recovery is carried out, and the risk of groundwater pollution is low. The secondary oil recovery is to utilize injected water or gas to achieve the effect of oil displacement by supplementing the formation pressure, so as to realize the oil recovery. In the tertiary oil recovery, chemical substances including a surfactant, a polymer or alkaline water and the like are injected into a reservoir, so that the physical properties or the chemical properties of oil, gas, water and rocks are improved, the oil displacement effect is achieved, and the crude oil recovery is further realized; the mode may have great influence on physical properties such as formation porosity, permeability and the like, and may change the dominant migration channel of oil and gas in the formation, possibly causing oil-water channeling and high risk of groundwater pollution. The corresponding relation between the mining mode and the comprehensive antifouling performance of the underground water can be as follows: for primary oil recovery, secondary oil recovery and tertiary oil recovery in the exploitation mode, the comprehensive antifouling performance of underground water may become worse in sequence.
The production time is mainly considered by the construction time of an oil production well and a water injection or gas injection well, the earlier the construction time is, the more seriously the wellbore material in the well bore is aged, the later the drilling and cementing process is, the worse the quality may be, the higher the possibility of crude oil leakage is, and the higher the risk of groundwater pollution is. The corresponding relation between the mining time and the comprehensive anti-fouling performance of the underground water can be as follows: the earlier the mining time, the worse the overall anti-fouling performance of the groundwater may be.
The inherent anti-fouling performance indicator may comprise at least one of: underground water burial depth, net supply amount, aquifer medium, soil medium, terrain gradient, aeration zone medium and aquifer hydraulic conductivity coefficient. The groundwater depth, net recharge, aquifer medium, soil medium, grade of terrain, aeration zone medium, and aquifer hydraulic conductivity may be indicated by letters D, R, A, S, T, I and C, respectively.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., 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, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.

Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.
