| 摘 要： | 依据岩石薄片分析,利用成岩作用定量分析及成岩演化等技术,对新场地区上三叠统须家河组须二段砂岩储层进行详细研究.结果表明:虽然须二段储层普遍具有低孔低渗的特征,但亦存在孔隙发育的优质储层段;优质储层主要发育在具有较高的成分成熟度和结构成熟度,粒度较粗,岩屑含量相对较低的砂岩中,在成岩过程中优质砂岩储层抗压实能力强;早期绿泥石与自生石英共同起到了抗压实的作用,保存较多的原生孔隙,提供了有利的渗流通道,有利于后期溶解作用形成大量次生孔隙.

| Abstract: | Based on the rock thin section analysis,the sandstone reservoirs of member 2 of Xujiahe formation,upper Triassic in Xinchang area were studied by using technologies of quantitative analysis of diagenesis and diagenetic evolution.The results show that the reservoirs have the characteristics of low porosity and low permeability in Xinchang area,but the high-quality reservoirs with pore developed also exist.The high-quality reservoirs developed in sandstone with high maturity and structure maturity,coarse grai... |
