摘要
介绍了用以分析储层岩石孔隙结构及渗流性质的若干函数,针对其在应用中所存在的计算规模过大的问题,提出了优化局部孔隙度分布模型、局部渗流概率模型的方法,改善了不同测量单元间大量子问题重复计算的情况。实验结果表明,该算法具有良好的可扩展性,改进后的算法在保证正确性的前提下,效率明显提升。
Several functions which are widely used to analyze the microstructure and percolation- properties of reservoir rock are introduced. Some models which can optimize the Local Porosity Distribution（LPD） and Local Percolation Probabilities（LPP） are proposed to solve the problem of repetitive computation among different measure units, therefore cut the amount of computation. The results indicate that the optimized models bear better expandability and higher efficiency under the premise of ensuring the correctness.
