Spectrum logging is an important method of dynamic monitoring in oil-field development,which used widely in oil-field such as high-precision C/O spectrum and NLL etc.

The application of reservoir modeling strengthens the ties of all segments in the later stage of oil-field development.

Based on multilevel fuzzy assessment and the practical situation of the oil field exploitation, a model of two levels fuzzy comprehensive assessment was developed in this paper.

The paper analyzed three kinds of accidents that affect ground water-resource during oil field exploitation, indicted the greatest risk was the leakage of the injection well wall.

One of the crucial issues in reservoir engineering study is how to choose pattern well spacing in order to reach the highest re- covery and optimal economic efficiency by waterfooding process for field development project designing and well pattern infill or adjust- ment.

An important work of field development is to analyze the influence factors of recovery efficiency and the potential of improving recovery factor.

According to shortcomings of the present prediction approach to dynamics index of field development and the principle of wavelet neural network (WNN), this study provides a new dynamics index prediction model using WNN, which can be applied to the actual prediction, and studies the model solution.
