| 摘 要： | 根据铸体薄片、扫描电镜、高压压汞、恒速压汞、核磁共振等分析和化验资料,研究三塘湖盆地牛圈湖区块齐古组、头屯河组砂岩储层特征,结果表明：该套储层岩性为岩屑砂岩,成分和结构成熟度都偏低;储集空间以粒间孔和溶蚀孔为主;储集性能差到中等,原始产能低,非均质性强。结合生产动态状况,选用喉道半径、有效孔隙度、可动流体饱和度、启动压力、孔喉半径比等低渗透储层评价新参数将齐古组、头屯河组储层划分成3类,分类结果适合地区实际。

| Abstract: | This article analyzes the sandstone reservoir characteristics of Qigu Formation and Toutunhe Formation in Niuquanhu Area of Santanghu Basin based on the data of cast sections,scanning electron microscope,high pressure mercury penetration, mercury penetration of constant speed,nuclear magnetic resonance. The study results show that the reservoir lithology is lithic sandstone. The pore space is mainly the intergranular pores and denudation pores. The reservoir property is from poor to middle. It has a poor or... |
