井间物性预报的一种尝试—样条函数法的应用

本文提出了在数据稀疏而又没有先验模式的条件下进行井间物性参数预报的“先局部后整体“的研究方案，先对局部数据的分布模式进行拟合，获取一个截面，然后用样条函数法对该截面上的物性参数进行插值，得到截面上的预报值，从而使数据大大增加，为区域上的进一步插值提供了可资利用的数据。经与沉积相带展布形势对比，证明所作预测基本可信。

Inter-Well Prediction for Permeability:An Application of Spline

The prediction of inter-well permeability is of great significance both in theoryand application. Under the conditions of spare data and lacking of prereqnisite models,we propose a prediction methodology called from local to whole in this paper. We searchfor an intersection and then interpolate permeability along the intersection in terms ofspline approximation. We thus obtain permeability on the intersection and enormouslyenlarge our data set.This provides much more usable and reliable data for furtherprediction. It is indicated by comparing with facies distribution that our approach is inthe right direction.
