A New Approach for Oil Drilling Bit Selection with Fractal Theory

Abstract:

In the oil drilling engineering, the choice of the best bit-type can improve penetration rate, shorten the drilling cycle time and speed up the oil field exploration and development pace. The drill bits type optimal selection has important meaning in oil drilling engineering. Based on the brief introduction of fractal theory, it pointes out that the fractal theory can describe the depositional sequence of formations with self-similar characteristics in this paper. It puts forward a method of calculating correlation dimension with multivariate model according to log information. It has also established statistical relationship between correlation dimension and the working performance standard of bits. At the end of the paper the bit types selection method, adopting the correlation dimension, has given out. This method is practically feasible through the example validation.
