| 摘 要： | 随着油气田开发难度的加大和技术的进步,储层随机建模技术已经成为储层表征的主要手段.基于地质统计学理论的认识,并结合模拟退火算法,本文研究了退火随机模拟储层地质模型,其结果表明该方法是一种易理解、易实现、较灵活、适应性强、较实用的算法.应用该方法可以建立渗透率、孔隙度、含油饱和度,以及波阻抗等参数的空间分布模型,这些模型很好的保持了已知数据所反映的储层空间特征,并真实地展现了各种参数在储层内的分布,为油气田储层预测和开发提供依据.

| Abstract: | With the increasing difficulty of oil and gas field development and technological progress,the reservoir stochastic modelling technology has become the primary means of reservoir characterization.Understanding of the theory based on geostatistics and simulated annealing algorithm,we study the annealing stochastic simulation of reservoir geological model,and the results show that the method is a intelligible,easily achievable,agility,strongly adaptable and useful classical algorithm.This method can create the soatuol distribution model of permeability,porosity,oily degree of saturation,and wave impedance and so on.These models woll retain that known data reflect characteristics of the reservoir space,They provide the basis for reservior prediction and exploitation. |
