摘要
本文在岩心观察的基础之上,结合样品的物性分析、薄片分析、扫描电镜等测试分析,系统的开展了吐哈盆地玉北地区克拉玛依组储层特征研究,分析成岩作用对储层质量的影响。研究表明:克拉玛依组砂岩储层主要经历了压实、胶结和溶蚀等成岩作用;压实作用是导致储层物性变差的主要因素,溶蚀作用是研究区最主要的建设性成岩作用类型,主要表现于长石矿物的溶蚀,其有效的改善了储层物性。
On the basis of core observation,combined with physical property analysis,thin section analysis,scanning electron microscopy and other test analysis of samples,this paper systematically carried out the research on the reservoir characteristics of Karamay Formation in Yubei area of Turpan Hami basin,and analyzed the influence of diagenesis on reservoir quality. The study shows that the sandstone reservoirs of Karamay Formation mainly experienced diagenesis such as compaction,cementation and dissolution;Compaction is the main factor leading to the deterioration of reservoir physical properties,and dissolution is the main constructive diagenesis type in the study area,mainly manifested in the dissolution of feldspar minerals,which effectively improves the reservoir physical properties.
