摘要 绿泥石是碎屑储集岩中较常见的粘土矿物之一。经长期研究发现,绿泥石粘土矿物在储层中的分布和赋存状态对储层孔渗性有重要的控制和影响作用。该文介绍了粘土矿物绿泥石的微观特征以及它在碎屑岩中的各种赋存状态。通过对绿泥石矿物的组成、含量、物理化学性质、成岩变化特征以及在储层孔隙中的分布特征的研究,探讨了绿泥石在储集岩的孔隙保护和演化中所起的作用,为储层的孔渗预测和储层评价提供理论和实际依据。 Chlorite (being a clay mineral) is one of the common minerals well developed in the sedimentary clastic rocks. It has been found that the distribution and occurrence of chlorite plays an important role in controlling and affecting the pore permeability in the reservoir. In this paper, the microscopic (characteristics) and various occurrences of chlorite are presented and its compositions, contents, chemical and physical properties, diagenetic variation and distribution in the pore of reservoir are discussed so as to understand the effect of chlorite on the protection of pores in the reservoir rocks. The research provides theoretical and practical evidences for the prediction of pore permeability and the evaluation of reservoirs in oil and gas fields.
