| 摘 要： | 本文在沉积相和成岩作用研究的基础上,对白庙地区沙三段的储层类型及其特征进行了阐述,提出了四种成岩相:碳酸盐胶结相、二氧化硅胶结相、杂基充填压实相和喷出岩及长石溶蚀相,讨论了碳酸盐胶结型、杂基充填压实型、二氧化硅胶结型和孔隙等四种储层类型及其特征。前三种储层类型为该区较典型的低孔低渗储层类型,物性差。第四种是该区主要气储集类型,储层特征与沉积相有密切的关系。沟道沉积的低成份成熟度和较高的结构成熟度的砂岩是比较理想的气储集岩相。

| Abstract: | Based on the study on the sedimentary facies and diagenesis, the reservoir types and their features of S3 members has been described. The reservoir has four diagenetic phases of carbonate-cemented,quartz-cemented mat rixfilling-compacted and extrusive rock fragments and f eldspardissolved. Four varieties of reservoir types and their characteristics are discussed, namely, carbonate-cemented, quartz-cemented, mat rixfilling-compacted and porous. The first three types are the reservoirs with typically low porosity and permeability in the area, and the last one is the main reservoir of gas accumulation. The reservoir features have an intimate relation to sedimentary facies. The sandstones deposited in turbidity channels with low composition maturation and higher texture maturation are lithofacies favorable to oil and gas accumulation. |
