运用层序地层手段，结合主要探井、地震资料，确定对比标志层；通过钻井，测井资料，划分基准面旋回，建立地层格架。通过关键井单井相、岩心观察和描述，编制综合井柱状图。经薄片鉴定、扫描电镜及X－衍射粘土矿物分析，认为储层颗粒整体较粗，胶结物含量低、成分成熟度和结构成熟度高，普遍含塑性岩屑、发育亩电利石等多因素共同导致了储层的致密化。储集空间主要为粒闽孔和粒内溶蚀孔。

By means of the sequence stratigraphy and combining with main exploratory wells and seismic data the comparative key bed was determined. The sedimentary base cycles was divided and the stratigraphic framework was established with the drilling and logging data. The columnar section of comprehensive well was made through the study of single-well phase of key wells, the observation and description of cores. By thin section authentication, electron microscopy scanning and X-ray diffraction of clay mineral analysis,the grain size of particles composed the reservoirs was quite coarse as a whole,and the low cement content,low compositional maturity and high textural maturity,generally with plastic debris,and the development of illite and many other factors led to the reservoir compaction. Accumulation capacity of the reservoirs mainly displays intergranular pores and intragranular dissolution pores.
