长石溶蚀作用是碎屑岩储层成岩过程中重要的成岩事件。储层中长石颗粒次生溶孔普遍存在,镜下微观特征表明长石溶蚀越强烈,溶蚀产物越富集,因此.长石溶蚀能否有效改善其储层物性值得商榷。以普通和铸体薄片为基础,利用人、机交互图像分析技术,通过面积百分含量法,精确统计了长石溶蚀量和溶蚀产物含量;结合储层物盐、流体包裹体及储层孔隙结构等资料,系统分析了长石溶蚀作用和溶蚀产物特征、长石溶蚀成岩环境及长石溶蚀对储层物性的影响,
Feldspar dissolution is an important diagenetic event during the diagenesis of clastic reservoirs. The secondary dissolution of feldspar particles in the reservoir is ubiquitous, and microscopic microscopic observation shows that the stronger the dissolution of feldspar is, the more corrosion products are enriched. Therefore, it is debatable whether feldspar corrosion can effectively improve the reservoir physical properties. Based on the ordinary and cast thin films, the dissolution rate of feldspar and the content of dissolution products were accurately calculated by the method of human-computer interactive image analysis and the area percent content method. Combining the characteristics of reservoir salts, fluid inclusions and reservoir pores Structure and other data, systematically analyzed the influence of feldspar dissolution and erosion product characteristics, feldspar dissolution diagenetic environment and feldspar erosion on reservoir physical properties,
