克里金法等在储层评价中的应用

Application of Kriging to the Reservoir Evaluation

从克里金法基本原理入手，介绍了克里金法和多种信息迭合法在乌尔逊凹陷大磨拐和级储层研究中的应用。乌尔逊凹陷探井少，资料缺乏，克里金法的应用为研究获取了比较符合实际的各类物性参数等值线图。在这些等值线图的基础上，应用多种信息迭合评价法评价了3个层段的储层。

Beginning with the basic principle of kriging,the authors introduce the application of krigingand multiinformation integrated approach to the reservoir evaluation in Wulsun Sag. Because there is afew wildcat well and data is lacking in the say, the isopleth maps of the variable physical parameters can be obtained onlyusing kriging. Based on the isopleth maps, the reservoirs of three members are reviewed by using multiinformation integrated approach.
