产品介绍

利用PetraSim解决具有挑战性的地下水流问题。
PetraSim是一个用于TOUGH2仿真器的图形界面,它由Lawrence Berkeley National Laboratory开发。流体在孔隙和裂隙介质传热中,TOUGH2和它的衍生软件具有强大的模拟功能。TOUGH2代码解决的问题包括从Yucca山地下水流到多元环境整治等。PetraSim通过一个交互式的3D环境,使建模者能够访问TOUGH2的功能,包括网格生成、参数定义和结果显示。
PetraSim降低了使用TOUGH2的难度,让分析师专注于模型,同时自动处理TOUGH2输入和输出文件复杂的细节。
PetraSim包含TOUGH2(v2), T2VOC,TMVOC和 TOUGHREACT(v1.2)执行文件。也支持TOUGH 2.1和TOUGHREACT 2.0,但是需要额外付费购买。此外,还支持HydrateResSim,必须从NETL获取,才能与PetraSim一起使用。PetraSim还包含了对TOUGHREACT v3.0和TOUGHREACT-Pitzer的部分支持。
包括CSV文件的输出(用于界面中的结果可视化)和一些旨在改进地热模型的更改。包括(但不限于)以下内容:
● 确定油井启动时间。这就避免了在现场规模的地热生产预测中对大量的油井进行建模时需要多次重启。
● 指定生产力指数(PI)和油井每一层的流动压力。
● IAPWS-IF97相关纯净水添加到标准TOUGH2 EOSs中。这些方法将“TOUGH2”的使用范围扩大到接近临界条件(T>350°C)和地热地质条件(P>1000 bara)。
● IAPWS 2008纯净水和蒸汽的粘度配方添加到标准TOUGH2 EOSs中。
● 使用源/汇名称对源/汇单元进行分组。这使得当多个井相交于同一单元时可以正确分配生产。
● 在指定的时间步长写入SAVE文件。
● 在GOFT文件中为EOS2和EWASG提供额外的输出结果。
● EOS2和EWASG中新毛细管压力和焓值选择。
● EOS2相变过程中提高收敛。
PetraSim和仿真支持的应用包括
● 耦合过程建模(热、水、化工、机械、生物)
● 碳吸收和其他类型的注入
● 甲烷水合物分解与回收
● 核废物库的性能评估
● 地热储层研究

3D建模

PetraSim全面支持3D建模。用户可以导入现有的3D层数据,并使用它来定义几何模型。用户可以将材质属性分配给层,并通过模型定义矿井。

网格生成

PetraSim支持多个网格选项。最基本的是一个矩形网格,在这个网格中,矿井根据所在的区域分配属性。这个网格提供了最可靠的收敛特性。如果希望网格与层一致,则可以使用矩形或Voronoi一致网格来完成。

支持TOUGH EOS选项

已经针对许多不同的状态方程(EOS)开发出了相应的TOUGH代码。例如,EOS3描述了在单一或两阶段条件下可以存在的水和空气,可以用于地下水或地热应用。EOS7C包括甲烷-二氧化碳或甲烷-氮气体混合物。应用包括地下地质碳封存地点和天然气储藏库。所模拟的组件包括水、盐水、非冷凝气体(CO2或N2)、气体示踪剂、甲烷和热量。

综合结果可视化

用户可以立即查看结果。PetraSim包括时间历史和3D等表面、矢量和等高线图。 数据可以导出到电子表格中,也可以用一种简单的格式适配像TECPLOT这样的图形软件。

帮助输出显示

所有输入都以这样一种方式组织起来,用户可以理解输入值是什么,以及在哪里使用它。例如,当指定相对渗透率输入时,给出方程,并显示渗透率曲线的动态预览。

其他强大的功能包括

● 完整的交互式模型创建和结果显示
● 3D模型操作和视觉反馈
● 在对话框中组织输入,帮助用户找到所需的控件

● 集成支持所有版本的执行代码
● 通过优化的TOUGH2和T2VOC可执行程序进行更快的模拟

常见问题答疑

Q:我已经有TOUGH2 simulator,我还需要购买PetraSim Core Module吗?
A:当您购买PetraSim时,必须要购买PetraSim Core module再加上至少一个interface module或您想要通过PetraSim运行的Simulators。
Q:PetraSim包含了哪些simulators?
A: PetraSim包含了一些免费的可执行文件来支持TOUGH2(v2.0),T2VOC,TMVOC和TOUGHREACT(v1.2)模型。PetraSim想要运行OUGHREACT v2 和TOUGH2-MP,需要拥有相关的simulators。
Q:PetraSim包含HydrateResSim simulator吗?
A:不包含,可以从NETL免费获得。
Q:PetraSim是否包含TOUGH2源代码吗?
A:不包含。
Q:如果购买了TOUGHREACT interface,可以访问TOUGH2吗?
A:TOUGHREACT interface不包含访问TOUGH2 simulators。在TOUGHREACT中, 您不能使用反应性运输工具,该模型的结果将是相同的或与相应的可执行模型运行几乎相同。所有的EOS模型,TOUGHREACT都不支持,但是TOUGH2支持。

PetraSim
Solve challenging subsurface flow problems with PetraSim
PetraSim is the graphical interface for the TOUGH2 family of simulators. Developed at Lawrence Berkeley National Laboratory, TOUGH2 and its derivatives are recognized for their powerful simulation capabilities for fluid flow and heat transfer in porous and fractured media.
The TOUGH2 codes have been applied to problems ranging from Yucca mountain groundwater flow to multi-component environmental remediation. PetraSim makes the power of TOUGH2 accessible to modelers through an interactive 3D environment that includes mesh generation, parameter definition, and display of results. PetraSim significantly lowers the barriers to TOUGH2 use by freeing the analyst to focus on the model, while automatically handling the complex details of TOUGH2 input and output files. PetraSim includes TOUGH2, T2VOC, TMVOC, and TOUGHREACT executables.

Models Supported by PetraSim
PetraSim supports the following models:

TOUGH2 is a general-purpose numerical simulation program for multi-phase fluid and heat flow in porous and fractured media. It belongs to the MULKOM family of codes, developed in the Earth Sciences Division of Lawrence Berkeley National Laboratory for applications in geothermal reservoir engineering, nuclear waste disposal, and unsaturated zone hydrology.

EWASG (included in the TOUGH2/T2VOC module) has been developed within the frame of a collaboration among Aquater SpA, an engineering services company of the Eni Group (now incorporated into Saipem SpA), the International Institute for Geothermal Research (IIRG) (now incorporated into the Institute of Geosciences and Earth Resources (IGG) of the National Research Council of Italy (CNR)) and the Earth Sciences Division (ESD) of Lawrence Berkeley National Laboratory (LBNL). Geothermal fluids usually consist of complex mixtures of water, salts and gases. As the thermodynamic and transport properties of such mixtures affect reservoir conditions and performance, the EWASG (Equation-of-state for WAter, Salt and Gas) module has been developed for the TOUGH2 multipurpose numerical reservoir simulator to handle three-component fluid mixtures of water, sodium chloride and a slightly soluble non-condensible gas (NCG).

T2VOC is a TOUGH2 module for 3-phase flow of water, air, and a volatile organic compound (VOC). T2VOC was designed to simulate processes such as the migration of hazardous non-aqueous phase liquids (NAPLs) in variably saturated media, forced vacuum extraction of organic chemical vapors from the unsaturated zone (soil vapor extraction), evaporation and diffusion of chemical vapors in the unsaturated zone, air injection into the saturated zone for removal of volatile organics (air sparging), direct pumping of contaminated water and free product, and steam injection for the removal of NAPLs from contaminated soils and

TMVOC is a numerical simulator for three-phase non-isothermal flow of water, soil gas, and a multicomponent mixture of volatile organic chemicals (VOCs) in multidimensional heterogeneous porous media. It is an extension of the TOUGH2 general-purpose simulation program developed at the Lawrence Berkeley National Laboratory. TMVOC is designed for applications to contamination problems that involve hydrocarbon fuel or organic solvent spills in saturated and unsaturated zones. It can model contaminant behavior under "natural" environmental conditions, as well as for engineered systems, such as soil vapor extraction, groundwater pumping, or steam-assisted source remediation.

TETRAD, distributed by ADA International Consulting Ltd., Calgary, Canada, is a numerical reservoir simulator that can operate in four main modes: black oil, multicomponent, thermal, or geothermal. All of these modes may be combined with dual porosity. Features include definition of wells, grid refinement, and flexible boundary condition specification. PetraSim supports creation of input geometry and properties and plotting of results.

TOUGHREACT is a new extension of TOUGH2 that couples chemical reactions to fluid flow. Coupled modeling of subsurface multiphase fluid and heat flow, solute transport, and chemical reactions can be used for assessment of waste disposal sites, acid mine drainage remediation, contaminant transport, groundwater quality, CO2 sequestration, and mineral alteration in geothermal systems. TOUGHREACT can be applied to porous and fractured media with physical and chemical heterogeneity. The model can accommodate any number of chemical species present in liquid, gas, and solid phases. A variety of equilibrium chemical reactions are considered, such as aqueous complexation, gas dissolution/exsolution, and cation exchnage. Mineral dissolution/precipitation can proceed either, subject to local equilibrium or kinetic conditions. Changes in porosity and permeability due to mineral dissolution and precipitation can be considered.

TOUGH-Fx/HYDRATE v1.0 is a new code, developed by LBNL, that simulates the behavior of hydrate-bearing geologic systems. By solving coupled equations of mass and heat balance, TOUGH-Fx/HYDRATE can model the non-isothermal gas release, phase behavior and flow of fluids and heat under conditions typical of common, natural CH4-hydrate bearing deposits (i.e., in the permafrost and in the deep ocean sediments) in complex formations.
