Microscopic Geological Factors of Movable Fluid Distribution in the Tight Sandstone Gas Reservoir:Taking the He 8 Reservoir in the East of Sulige Gas Field as An Example
摘要
Abstract
Taking the He 8 tight sandstone gas reservoir in the east of Sulige gas field as an example,the authors conducted a series of experiments including nuclear magnetic resonance,constant-speed mercury injection, casting thin slice,reservoir property,X-ray and so on.With all these techniques,we discussed the microscop-ic geological factors which affect the distribution of movable fluid.The researches show that:the saturation of movable fluid in He 8 reservoir was low while the distribution of T2 spectrum was bimodal pattern with high left side and low right side.The filling of clay mineral and pore types were the key factors that resulted in complicat-ed pore structures.Pore structure had great impact on the saturation of movable fluid.Facial porosity,throat ra-dius,the rate of pore radius and throat radius were the key factors which affected the saturation of movable flu-id.The effective pore volume and sorting coefficients affected the saturation of movable fluid obviously,while the physical properties of reservoir,clay mineral,effective throat volume and pore radius had moderate effect on the saturation of movable fluid.关键词
