摘要
本区砂岩储集层具有中孔低渗特点。受沉积作用影响，砂岩成分成熟度低，砂体原始物性差。砂岩已进入晚成岩Ａ亚期阶段。砂岩原始沉积特征和成岩作用改造后细孔喉分布优势是导致低渗透的原因。
The sandstone reservoir of this area is characterized by medium porosity andlow permeability. The low maturity of sandstone components is low because of sedimentationand poor primary physical property of sandbody. Sandstone has entered the late diagenesis Asubage period. It is the primary sedimentary characteristics of sandstone and the fine porethroat distribution preponderant through diagenesis modification that caused low permeabili-ty.
