The Application Of Random Fractal In The Forecast Of Reservoir Parameter

With the rapid development of our country economy, lots of energy is demanded increasingly. Lack of demand has become a serious problem day by day, especially lack of petroleum. It is an important task into which many a scientists put their hearts how to solve the problem of lack of energy.At present,the rule of reservoir parameter distribution is a core when the oil gas pool describes. At the same time it is a core content when the fine oil deposit description.The reservoir parameter is an important basis of the oil layer appraisal, the reservoir parameter forecast has the vital significance in the oil gas exploration development. This article's research is the distribution of reservoir parameter(porosity, permeability and so on).At first, this article has carried on the summary to the domestic and foreign reservoir parameter research,it outlined the principle of fractal ,the theory of Fractal Brownian Movement and random fractal interpolation method. Based on the theory of random fractal, this article use the analysis of R/S to estimate the log's Hurst.The Hurst describes this region whether has the long distance relevance. According to it we can distinguish the reservoir parameter,and forecast the reservior parameter. This article uses the random fractal interpolation to forecast the reservoir parameter by the graph form,specially the curved surface of fractal interpolation.This method applied in the Qinghai some oil field, the rusult show that this method may be objective, feasible and effective.So we can use the method to describe the reservoir parameter of no well point.
