| 摘 要： | 通过岩心分析及镜下观察等研究，认为郑庄油区长6油层组储层岩石成分以长石砂岩为主，岩石成分成熟度低，结构成熟度中等，储层物性以低孔、低一特低渗为主，储层展布主要受沉积相控制，沉积类型为三角洲前缘亚相沉积。水下分流河道微相是该区的主要储集岩相。长6油层组浊沸石溶蚀作用比较发育,对改善储层物性起到关键性作用。 |

| Abstract: | Based on the core analysis and microscopic observation,it is believed that the rocks of Chang 6 reservoir are mainly composed of arkose with low compositional maturity and medium texture maturity.Reservoir properties are mainly low porosity and low-super low permeability.The reservoir distribution is mainly controlled by sedimentary facies.The sedimentation type is mainly delta front subfacies.Subaqueous distributary channel and mouth bar sand bodies are the main reservoirs.The denudation of laumontite developed well in Chang 6 reservoir,which plays a key role to the reservoirimprovement. |
| Keywords: | Chang 6 reservoir reservoir characteristics diagenesis Zhengzhuang oil region Ordos Basin |
