A geomechanical model and a multiphase black oilmodel are iteratively coupled in this paper. Parallel computingis employed to handle large scale problems by benefiting fromits features of distributed memory storage and efficient runtimereduction. The finite element method and the finite differencemethod are employed to discretize the two models, respectively. The geomechanical model is developed with...
In recent years, polymer flooding has become a mature technology to improve the reservoir recovery rate and has been successfully implemented in many oil fields. Because of high operating costs of a polymer flooding project and the impact to the environment, the polymer injected per unit volume should be tracked for each polymer flooding pattern. Hence, the full-field reservoir simulations with fine-scale...
Tank situation display system is a basic component of the tank integrated simulator. This paper describes the design process of virtual instrument for tank integrated simulator based on LabWindows. The hardware architecture and diagrams of system are introduced first. The software module architecture and design development process are given later. The research of several key issues is focused on,...
Waveform inversion of crosshole data based on acoustic wave equation is investigated in this paper. The inversion is set as an optimization problem with the Lagrange multiplier function. The Tikhonov regularization is adopted in objective function. The gradient of the objective function is generated by solving the adjoint equation of the forward problem with the finite difference method. In order...
Today, Massive Multi-player Online Game (MMOG) has taken an important part in the field of entertainment. But its increasing requirement of resources has brought a heavy burden to the game server. To address this problem, we propose a Structured Multi-Agent (SMA) model which divides the resources into groups by the Area of Interest (AOI) and builds itself on the pastry protocol. Then, every other...
