摘要

摘要: 利用四五家子油田取心井的岩石铸体薄片鉴定、扫描电镜观察、粘土矿物X衍射分析等资料, 研究了泉二段储层的成岩作用、成岩演化序列, 并划分了成岩作用阶段.泉二段储层可划分为4种成岩储集相类型, 储集物性由好至差依次为, A相: 弱胶结中等压实粒间孔成岩储集相; B相: 胶结物溶解次生孔隙成岩储集相; C相: 杂基充填强压实微孔隙成岩储集相; D相: 早期方解石胶结成岩储集相.详细阐述了各类成岩储集相的特征, 并对其成因进行了分析.最后探讨了泉二段储层的储集空间类型及其演化模式.

Abstract: Based on the analytic data of casting thin section, scanning electron microscope, X-ray diffraction of clay minerals of well core samples at Siwujiazi oilfield, the diageneses, diagenetic sequences and stages of the Second Member of Quantou Formation of the Lower Cretaceous were studied. The study suggests that its reservoir rocks can be divided into 4 types of diagenetic-reservoir facies, i.e. facies A, which has undergone weak cementation and middle compaction and has interparticle pores; facies B, in which calcite cements have been greatly dissolved and secondary dissolution pores have been developed; facies C, which has undergone strong compaction and has micro pores, showing matrix filled in interparticles; facies D, which has undergone early calcite cementation. The characteristics and origin of each diagenesis-reservoir facies are described in detail. Finally the types and evolution of pore space are discussed.
