| 摘 要： | 影响储层性质的因素较多,并且这些因素之间往往具有错综复杂的关联性,针对这些特点,以四川盆地川中磨溪气田嘉陵江组嘉二段碳酸盐岩储层为例,优选孔隙度、渗透率、含水饱和度、排驱压力、平均孔喉半径、储层有效厚度以及渗透率变异系数、突进系数和级差作为储层评价因素,采用模糊聚类分析法评价储层的质量.评价结果与气田实际产能具有很好的一致性. |

| Abstract: | There are many factors of influencing reservoir characteristics,and there is complex correlation among the factors.Taking the carbonate reservoir of Jia-2 member of Jialingjiang formation in Moxi gasfield in the middle of Sichuan Basin as a case,the complex carbonate reservoir is quantitatively evaluated using the fuzzy cluster analysis.The porosity,permeability,water saturation,displacement pressure,average pore-throat radius and effective thickness of the reservoir and the variation coefficient,mutation coefficient and level difference of the reservoir permeability are selected as the factors of influencing reservoir characteristics.The evaluation result is consistent with the practical productivity of the reservoir. |
| Keywords: | carbonate reservoir complex reservoir quantitative evaluation fuzzy cluster analysis Moxi Gas-field |
