巴喀地区八道湾组致密砂岩储层“甜点”预测
Tight Sandstone Reservoir“Sweet Spot”Prediction of Badaowan Formation in Baka Region
摘要
Abstract
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.关键词
