# 水平井阵列持水率测井资料成像插值算法分析Analysis on Imaging Interpolation Algorithm for Logging Data of Water Holdup Array Tool in Horizontal Wells

With the progress of science and technology, imaging observation technology was more and more advanced. The large well logging companies abroad pushed out the full well logging tool of array holdup applied in flow imaging logging; this tool could measure the local water holdup at the circular ring inner wall of the casing at the same depth. Based on data feature of logging data of CAT, the principles of simple inverse distance weighting value, Gauss basis function interpolation, ordinary Kriging interpolation and variogram function inverse weighting method were analyzed in this paper. The comparison of these interpolation methods both in theory and in practical application shows that the result of Kriging interpolation method is better than that of the other three methods. The result can better show the distribution of the medium of oil-water in the well and total water holdup clearly and directly.
