Fractal Feature about the Pore Structure and Controlling Factor in Tight Glutenite Reservoir in Baikouquan Formation of Mahu Depression in Junggar Basin
摘要
Abstract
T he tight glutenite reservoir has many chareateristics , such as the complex pore structures ,various types of pores ,strong heterogeneity ,difficult pore structure characterization . With the mercury injection capillary pressure curve , this thesis uses many fractal models to calculate the fractal dimensions of the tight glutenite reservoir .Then it analyzes the relationship between fractal dimension and porosity ,permeability ,pore structure characteristic parameter by the cross plot technique .It shows that the fractal dimension gained from the capillary buddle subsection model can better present the pore structure tight glutenite reservoir . Finally , the influence factors of fractal dimension are discussed in four aspects of rock grain‐size , clastic constituents ,clay mineral and stype of pore .It is denmonstrared that clastic constituents ,clay mineral are the influence factors of fractal dimension .The various types of pore and complexity are direct performance for fractal dimensions .The actual applications show that the greater oil production capacity ,the smaller the fractal dimension ,w hich has the close relation and through fractal dimensions oil production capacity is evaluated . It is based on the pore fractal characteristics ,which provides an effective and new research way for the evaluation of pore structure of the reservoir in the studied area .关键词
