| 摘 要： | 指出了全直径岩心分析的Archie参数(m、n)对非均质储层含油(气)性评价的重要性.使用新疆测井公司开发的全直径岩心多参数分析实验装置及实验方法，以DQ油田XX区块的非均质火成岩气层评价为例，由7块全直径岩样该获得了储层的物性和Archie参数.当应用于该储层含气饱和度估算后，与密闭取心饱和度分析的含气饱和度结果比较，含气饱和度估算误差大致在5%以内，较按Archie参数的确省值(m=n=2)估算的含气饱和度的精度高 10%左右.考虑到非均质储层在岩性、物性、孔隙结构的特殊性，推荐“真正”使用全直径岩心分析方法应用于非均质储层的物性、含油(气)性的评价，并重视模拟油藏条件的全直径岩心分析装置的开发.

| Abstract: | An idea that Archie's parameters(cementation exponent m,saturation exponent n) should be measured by whole core analysis for the estimation of oil and gas saturation in inhomogenous reservoir was put forward.With the employment of whole core multi-parameters measurement device and measurement method developed by Xinjiang Well Logging Company,7 whole cores from inhomogenous igneous reservoir in the XX area of DQ oil field were measured.When the Archie's parameters were applied in the estimation of oil and gas saturation,the error of gas saturation was within 5% compared to the gas saturation from sealed core,was about 10% higher than the estimation by classical Archie parameters(m=n=2).With a view to inhomogenous reservoir's special property in lithology,porosity,penetrability and pore structure,whole core analysis should be used for the estimation of oil saturation in inhomogenous reservoir.Also,it was necessary to pay more attention to the development of full-size core multi-parameters measurement device that can simulate the reservoir condition. |
