通过储层砂体岩芯观察、铸体薄片鉴定、粘土矿物X衍射分析、扫描电镜,压汞测定等方法,得出吴起地区吴410井区长6储层岩石学特征,物性特征以及储集特征,分别为长6储属于低孔低渗储层;储层岩性以长石砂岩、岩屑长石砂岩为主,胶结物主要为绿泥石,伊利石,铁方解石等;孔隙空间主要有粒间孔,长石溶孔和微孔隙三大类。通过对储层特征研究,可为下一步勘探开发提供地址依据。 The lithology, physical property and reservoir of Chang 6 reservoir in Wu 410 well area in Wuqi area are obtained through the observation of core of reservoir sand body, identification of cast thin slice, X-ray diffraction of clay minerals, scanning electron microscopy and mercury intrusion measurement They are mainly composed of feldspar sandstone and feldspathic feldspar sandstone, and the cements are mainly chlorite, illite and iron calcite. The main pore space is mainly composed of low porosity and low permeability reservoirs. Intergranular pores, feldspar dissolved pores and micro-pore three categories. Through the study of reservoir characteristics, it can provide the address basis for the next exploration and development.
