Random Fractal Crack Model

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,exploitation and recognition of petroleum reservoir in fracture is an effective approach to improve the output of petroleum and gas . Scientific research shows that petroleum reservoir with plentiful output all over the country in the world is petroleum reservoir in fracture.Therefore,it is significant to exploit petroleum reservoir in fracture.Fractures are not only main spaces of petroleum reservoir ,but also are important petroleum percolating channels.Growth and distribution of fractures basically affect outputs of petroleum .However, Growth ,forming and distribution of fractures are controlled and affected by many factors,which makes people have difficulties in exactly cognizing them. Yet,precise description and prediction of reservoir fractures is still an unsolved difficult problem of petroleum geology in the world.This subject derives from petroleum fracture modeling , the important project of knowledge innovation of institute of Physical Geography,Chinese Academy of Sciences(Beijing).The purpose in this paper is enriching the existing theory of fracture research by taking advantage of random fractal theory , providing researcher going in for fracture research with methods of fracture simulation,and further extending application of fractal technic .The task in this paper is that by combining professional knowledge of computer ,by making use of techno-OpenGL and VC++6.0 developing platform,in terms of two surfaces with character of self-affine in some scale size comprising single fracture,we apply the methods of simulating random fractal Brownian to simulate two surfaces with correlation in...
