摘要
通过对塔河油田艾丁地区13口探井岩石薄片及部分井铸体薄片的镜下观察,结合岩芯观察及扫描电镜资料,认为该区经历了多种成岩后生作用,根据成岩作用与孔隙的关系可以划分为建设性成岩作用及破坏性成岩作用两大类。其中对岩石储集性能破坏程度最大的成岩作用有压实、胶结及充填作用。而深部溶蚀、表生岩溶、破裂、压溶作用能够改善岩石的储集性能,提高岩石的孔渗能力。
According to identifying Ordovician carbonate rock-slices and casting-slices about AD1-AD13 etc. in AIDING aera of Tahe oil field, combining the observation of rock’s sample and the data of SEM , author consider that this area underwent manifold diagenesis. According to the relation among diagenesis and hole , diagenesis can be divided into two types: capability of building and capability of damage.The diagenesis causes damage to the capability of rock accumalation, which are :compaction and cementation and filling. But partes profunda chemical denudation、karst process、cracking and pressolution can improve the capability of rock accumalation and increase capability of porosity and permeability.
