Fractal features of development degree of Ordovicia paleokarst in the Ordos basin
-
Abstract
Oil and gas exploration practice shows that the development degree of paleokarst has influence on reservoir quality.However,there is no means of quantitative description for such a feature.This paper analyzes the development degree of the Ordovician paleokarst in the Ordos basin based on its fractal features.First,the fractal features of paleokarst were studied.Then,fractal algorithm was analyzed and its operation flow was designed.Finally,the paleokarst development degree was quantitatively described by fractal dimension combined with the drilling data,and the relationship between fractal dimension and reservoir was analyzed.Results indicate that the development degree of Ordos paleokarst shows fractal features,which reflect the development degree of paleokarst under certain geological conditions,and the fractal dimension of industrial gas wells is greater than 1.65.Therefore,using fractal dimension to classify the development degrees of paleokarst can improve the objectivity and accuracy of reservoir evaluation in areas with paleokarst. -
