The Longdong area in the Ordos basin is a typical fluvial reservoir with strong heterogeneity. In order to clarify distribution law of underground reservoirs area, it necessary establish and optimize 3D geological model characterize heterogeneity reservoirs. This great significance for accelerating exploitation tight sandstone gas southwest basin. study takes P2h8 member Ct3 research as an exam...

The Markov chain random field (MCRF) theory and the transiogram spatial measure were proposed several years ago. Basic sequential simulation algorithms based on simple MCRF models such as the Markov chain sequential simulation algorithm and the Markov chain sequential co-simulation algorithm have been developed and used in a series of application studies. However, misunderstanding of these two ...

seismic inversion is a method that extracts acoustic impedance data from the seismic traces. sourcewavelets are band-limited, and thus seismic traces do not contain low and high frequency information.therefore, there is a serious problem when the deterministic seismic inversion is applied to real dataand the result of deterministic inversion is smooth. low frequency component is obtained from w...

Many simulation problems can take advantage of distributed simulation approach when dealing with the huge timeor spacecomplexity and the conventional sequential solution is not satisfying. We have proposed and implemented an object-oriented toolset for developing both sequential and conservative distributed simulation architectures, based on a sound formal background and our previous experience...

LP.EventList if it has already been executed by the sequential portion (so that e.execTime 6 = ?1:0.) So if there is any event not yet simulated, it must be in either SuperStepList or LP.EventList. When the analyzer nds that: SuperStepList = fg and LP i .EventList = fg 8LP i the sequential event list must be empty. And since the set of events in the sequential simulation is the sum of every LP'...

A simple multiscale approach to the diffusion-driven adsorption from a solution to a solid surface is presented. The model combines two important features of the adsorption process: (i) the kinetics of the chemical reaction between adsorbing molecules and the surface; and (ii) geometrical constraints on the surface made by molecules which are already adsorbed. The process (i) is modelled in a d...

A new method is presented which combines a forward and an image operator (resolution function) to construct a simulated migrated seismic section from a geological depth model. To efficiently use this tool during seismic interpretation, a fast implementation is necessary. This is achieved by improving the performance of the serial algorithm.

This paper is motivated by the theory of sequential dynamical systems, developed as a basis for a mathematical theory of computer simulation. It contains a classification of finite dynamical systems on binary strings, which are obtained by composing functions defined on the coordinates. The classification is in terms of the dependency relations among the coordinate functions. It suggests a natu...

We propose three efficient sequential designs in the software reliability estimation. The fully sequential design the multistage sequential design and the accelerated sequential design. These designs make allocation decisions dynamically throughout the testing process. We then refine these estimated reliabilities in an iterative manner as we sample. Monte Carlo simulation seems to indicate that...
