摘要:
应用铸体薄片、扫描电镜、X射线衍射、物性分析等实验测试方法,对鄂尔多斯盆地姬塬地区长61段致密砂岩储集层的岩石学特征、成岩作用特征及其对储集层孔隙演化规律的影响进行了研究。研究表明:研究区致密砂岩储集层经历了复杂的成岩过程,成岩阶段到达中成岩阶段A期,部分已进入中成岩阶段B期的早期。通过对孔隙度定量演化模式的建立,发现压实作用是造成储集层致密化的最主要因素,使储集层孔隙度减少了21.52%,损失率为55.72%;胶结作用对储集层物性的破坏次之,孔隙度损失率为32.41%;溶蚀作用增加的孔隙度平均为4.36%,结合埋藏史模拟孔隙综合演化史,定量表征了埋深与成岩作用对孔隙度的影响。通过4块典型样品分析,进一步反映了研究区长61段属于压实型成岩改造,压实作用和胶结作用是引起储集层致密化的重要因素。
Abstract:
Based on the data of cast thin section, scanning electron microscopy(SEM), X-ray diffraction and physical property analysis, the paper studies the features of petrology and diagenetic process and their influences on reservoir pore evolution of Chang 61 tight sandstone reservoir in Jiyuan area, Ordos basin. The results show that the tight sandstone reservoir in the study area experienced a complicated diagenetic process and most of the reservoir has entered phase A of the middle diagenetic stage and the rest has been in the early phase B of the middle diagenetic stage. Based on the establishment of quantitative porosity evolution model, it is found that compaction is the main factor causing the reservoir densification which results in the decrease of the reservoir porosity by 21.52% with the porosity loss rate of 55.72%; cementation damage on reservoir is the secondary with the porosity loss rate of 32.41%; dissolution can increase the porosity by the average of 4.36%. Using burial history to match comprehensive porosity evolution history, the paper characterizes the influences of burial depth and diagenesis on porosity quantitatively. The analysis on 4 typical samples further indicates that the Chang 61 tight sandstone reservoir in the study area belongs to compaction-type diagenesis, and compaction and cementation are the key factors causing reservoir densification
