摘要

摘要: 评价泥页岩储层的好坏主要考虑泥页岩的含气性与泥页岩后期压裂开发的难易程度。据此,优选了与泥页岩储层优劣紧密相关的6项影响因素,包括有机碳含量、等温吸附气量、成熟度、孔隙度、伊蒙混层及脆性矿物含量。运用灰色关联理论,对鄂尔多斯盆地上古生界泥页岩储层进行了评价,应用储层综合评价指标(REI)可将储层分为3类:Ⅰ类储层,REI≥0.5;Ⅱ类储层,0.33≤REI<0.5;Ⅲ类储层,0.3≤REI<0.33。同时参考前人成果和经验数据,提出了该区海陆过渡相泥页岩储层的评价方案,并用图像的方式展示了不同储层的特征。

Abstract: In the estimation of shale gas reservoirs, the shale gas content and the difficulty for fracture development are the main influencing factors. Six critical factors were chosen, including organic carbon content, the amount of adsorbed gas, maturity, porosity, and the content of I/S and brittle mineral. According to the theory of grey correlation grade, the shale reservoirs in the Upper Paleozoic in the Ordos Basin were studied. The reservoirs were classified into three types based on the Reservoir Estimating Index (REI). When REI≥0.5, the reservoirs belong to type Ⅰ. When 0.33≤REI<0.5, the reservoirs belong to type Ⅱ. When 0.3≤REI<0.33, the reservoirs belong to type Ⅲ. Combined with previous studies, an estimation scheme of transitional facies shale gas reservoirs in the study area was proposed, and the characteristics of different reservoirs were shown with images.
