The Niuzhuang Oil Field is now at the early development stage, only with 20 wells. The porosity distribution given by limited logging data is too rough to guide the next work effectively. In this paper, seismic data of this oil field were used to predict the porosity distribution by five statistical methods. The porosity contour maps plotted by these methods show much more details than the contour map plotted by interpolating of the logging porosity values.
