储层微观地质统计分析发现，巴喀地区砂岩粒度与储层孔隙度和渗透率具有较好的相关性。通过建立测井解释模型，利用自然伽马曲线定量表征砂岩粒度参数及储层储集参数特征，在此基础上，根据储层微观参数地质统计分析和测井模型计算结果，应用储层微观地质统计参数反演与相干体分析技术相结合的预测方法，对巴喀地区八道湾组致密砂岩储层“甜点”分布特征进行了有效的预测。八道湾组致密砂岩储层“甜点”主要分布在柯柯亚构造带断背斜高部位及其紧邻的斜坡区，储层粒度较粗，渗透率相对较高，在一定范围内，孔隙度也相对较高，为巴喀地区致密砂岩气藏的有利储层分布区和有利勘探区。

According to the reservoir microscopic geostatistical analysis,the results show that the granularity of sandstone is in relatively good correlation with reservoir porosity and permeability in Baka Region. By building log interpretation model and with gamma curve,we get the parameters of granularity of sandstone and reservoir feater. Based on the geological reservoir microscopic parameter statistical analysis and logging model calculation results,and with the reservoir microscopic geological statistical parameter inversion and coherence analysis technology,we made prediction of tight sandstone reservoir sweet spot distribution of Badaowan Formation. The sweet spot of tight sandstone reservoir in Badaowan Fortamtion are mainly distributed in high faulted anticline of Kekeya tectonic belt and adjacent to the slope area. The tight sandstone reservoir of Badaowan is of granularity coarser,and relatively high permeability;within a certain range,the porosity is relatively high,which is favorable reservoir distribution area and favorable exploration area for tight sandstone gas reservoir in Baka Region.
