以随机模拟为主要方法,在对储层参数进行变量统计参数和变差函数分析的基础上，对新场气田上沙溪庙组JS2气藏地质研究和气藏描述成果进行定量化转变,建立了包括构造模型、物性参数模型和流体分布模型的三维地质模型。以此为基础，对有利区进行了预测。随机建模方法的应用，提高了气藏描述精度，为气藏储层改造及开发调整方案编制提供了可靠的依据。

Based on the analysis of the variable statistic parameters and variograms, the results of geological research and gas reservoir description in Upper Shaximiao Formation of Xinchang Gas Field were quantitatively transformed by taking stochastic modeling as the major method, therefore three-dimensional geological models were setup, including structural model, petrophysical model and fluid distribution model. Based on these models, prediction was made for favorable target area. By using stochastic modeling, degree of accuracy in gas reservoir description was greatly increased because it provides a reliable basis for reservoir stimulation and ad-justing development plans
