In order to solve the provenance of deep-water in Qiongdongnan basin, non-linear technology is used to analyze provenance in Lingshui 17-2 gas field, namely use the fractal dimension of natural gamma logs analyze provenance. This technique effectively avoids mineral components changes problem due to weathering, transportation, deposition and other effects. It achieved good results, opened up new ideas in deep-water provenance analysis. For the complex reservoir characteristics of deep-water, in order to effectively predict reservoir parameters such as porosity, permeability, etc., the paper based on nonlinear theory, using fractal model to predict reservoir parameters in deep-water of Qiongdongnan basin. And compared with the traditional method IDW, the results showed that the result of IDW is lower than the actual, but the difference is not obvious. The P-A result includes the actual results, we can predict reservoir parameters of unknown area based on the parameter, thus provide a basis for evaluating reservoir. The result of S-A model is much closer to the actual, This shows that the method can predict reservoir parameters deeper on the basis of P-A model, thereby obtaining more accurate information. Multifractal method can effectively obtain accurate parameter estimates at the point of no Well, its accuracy and predictive ability can achieve the purpose of less drilling, and less investment purposes and early results.
