Abstract:

Water-flooded zone identification of oil-saturated stratum is a difficult task during the middle-late period of the development, which needs an immediate solution. On the basis of preprocessing the well-log information standardization, the B-spline kernel is applied to oil water-flooded zone identification, and good recognition effect is obtained.

Key words: water-flooded zone ;support vector machine, B-spline kernel
