储层地质统计随机模拟

/ GEOSTATISTICAL STOCHASTIC SIMULATION OF RESERVOIR

储层地质统计随机模拟是近几年发展起来的高新技术，其最为突出的优点是：可以实现油气储层的精细描述和建模，定量表征和刻画储集层各种尺度的非均质性；可用于定量研究储层描述的不确定性，进而研究油气勘探和开发的不确定性和投资风险；可以综合多种来源的信息和资料，并把它们统一在同一个定量模型之中。文中综合论述了储层地质统计随机模拟的意义、方法和技术及其在油气勘探与开发中的应用，并讨论了联合模拟多个变量以及综合多种来源的资料等问题，指出在我国发展储层随机模拟技术有重要的实践意义。

The geostatistical stochastic simulation of reservoir is a new technique developed in recent years and has three main advantages: (1) Quantitative reservoir models can be constructed, and heterogeneities in different scales can be characterized by geostatistical stochastic simulation. (2) The uncertainty of reservoir description and the risk of exploration and exploitation can be appraised. (3) Different kinds of information and data can been integrated in a reservoir model during stochastic modeling. The significance, methods and application of reservoir geostatistical stochasic modeling in hydrocarbon industry, and other further problems such as joint simulation of multivariables, the methods for integrating different kinds of information and data are discussed. It is emphasized that beneficial and practical significance of reservoir geostatistical stochastic simulation will be gained in China.
