摘要:
准噶尔盆地石南21井区头屯河组低渗透砂岩储集层非均质性强,剖面上物性差异大。基于物性、压汞、铸体薄片等资料,从储集层微观孔喉结构出发,运用聚类分析方法,优选多项参数将储集层分为4类。石南21井区头屯河组以Ⅱ类和Ⅲ类储集层为主,储集层物性受泥质含量影响大,泥质含量增加,孔隙结构变差,渗透率降低。由于采用常规模型解释含泥质砂岩储集层渗透率误差较大,按泥质含量结合储集层分类,对4类储集层分别建立了渗透率解释模型。实际应用表明,所建模型解释结果与岩心分析数据吻合度较高,比常规测井参数模型解释精度提高了7.8个百分点,效果较好,可推广运用到其他含泥质的低渗透砂岩储集层。
Abstract:
The low-permeability sandstone reservoir of Toutunhe formation in Wellblock Shinan-21 of Junggar basin is characterized by strong heterogeneity and great physical property differences in profile. Based on physical property analysis and the data of mercury injection and casting thin section, regarding microscopic pore-throat structures of the reservoir, the reservoir can be divided into 4 types through parameter optimization by using cluster analysis method. The Toutunhe formation in Wellblock Shinan-21 is dominated by Type Ⅱ and Type Ⅲ reservoirs that are mainly influenced by shale content. The larger the shale content is, the poorer the pore structure and the lower the permeability will be. The error of permeability of shaly sandstone reservoir interpreted with conventional model is relatively large. According to shale content and combining with reservoir classification, the paper establishes 4 permeability interpretation models for the 4 types of reservoirs, respectively. The actual application shows that the new models can well match with core analysis data, the interpretation accuracy is improved by 7.8% compared with that of the conventional model and good effects have been gained, which can be widely used for other low-permeability shaly sandstone reservoirs
