Experimental evaluation on well pattern adaptability of ultra-low permeability reservoir using sandstone flat modelXIAO Qian-hua(肖前华)1, WEI Guo-qi(魏国齐)1, 2, YANG Zheng-ming(杨正明)1, 2, XU Xuan(徐轩)2... Research Institute, Langfang 065007, China)Abstract:As for ultra-low permeability reservoir, the adaptability of common nine-spot well pattern is studied through large-scale flat models made by micro......
of different factors on coefficient of permeability were discussed. The results showed that the increasing confining pressure will gradually decrease the coefficient of permeability, and this process... 30 kPa. Unlike confining pressure, an increase in temperature will increase the coefficient of permeability. It is noted that fracture surface roughness will also affect the variation of coefficient......
, permeability coefficient, porosity, water cement ratio, grouting time on diffusion radius, cement strength and their correlation were studied. Two numerical formulations were concluded by multiple non-linear regression analysis of the test data. The results show that on grout diffusion radius of influence is significant in the order of GIN value, permeability coefficient, water cement ratio and grouting......
