克立格法在储层预测中的应用
摘要
克立格法为地震、测井、地质、开发等资料的整合提供了有力的工具,在石油勘探和开发中有日益广泛的应用。本论文主要是从地质统计学的基本工具——变差函数入手,应用地质统计学中的普通克立格和协克立格方法对某区二维层面上的孔隙度进行预测,进而研究了克立格估计的各种影响因素,最后本文总结了克立格立格方法的特点及局限性,为防止在储层参数预测中不恰当的使用地质统计学起到了一定的指导作用。
Kriging provides a powerful framework of integrating seismic,well and geologic data.It is increasingly playing important roles in petroleum exploration and production.This thesis systematically starts with the research of variogram,which is the basic means of Geostatistics,studies the of 2-D reservoir porosity prediction by using the ordinary Kriging estimate and and Co-kriging estimate.And then research the affecting factors of Kriging estimate.Finally,the characters and limitation of Kriging estimate are summarized.This summary will contribute to avoiding potential pitfalls in Geostatistical practice.
