摘要/Abstract

摘要： 鄂尔多斯盆地苏里格气田苏48区块盒8段属于辫状河三角洲平原亚相沉积，非均质性强，开发难度大。以油气储层地质学、沉积学等知识为基础，利用铸体薄片、阴极发光、图像粒度、X-射线衍射、扫描电镜等实验手段，定量表征成岩作用对孔隙致密化的影响，依据成岩、物性和孔喉特征参数建立了成岩相定量划分标准，阐述了不同成岩相的特征差异。结果表明:研究区属于以岩屑石英砂岩和石英砂岩储集砂体为主的特低孔—超低渗油田；成岩作用的定性特征表明研究区主要处于中成岩B期，在压实—早期胶结—溶蚀—晚期胶结等一系列成岩演化作用下，机械压实是储层致密化的主控因素；根据成岩参数将研究区划分为4类成岩相，其中中等压实—石英弱加大—粒间孔—溶蚀相分布在分流河道中心，属于优质成岩相；中等压实—中等高岭石胶结—溶蚀相—晶间孔次之。通过对成岩相的定量划分和特征差异描述，明确了研究区特低孔喉形成机理，为精细描述苏里格气田储层提供了借鉴。

Abstract: The He 8 reservoir of Shihezi Formation in the Su 48 block of the west area of Sulige Gas Field of Ordos Basin belongs to braided river delta plain sedimentary subfacies.The development of reservoir is difficult because of the strong heterogeneity.This paper is based on the knowledge of oil and gas reservoir geology,sedimentology,etc.The quantitative characterization of diagenetic effects on pore densification were studied by conducting various experiments including cast thin section,cathode luminescence,image particle size,X-ray diffraction,scanning electron microscope.The quantitative classification standard for diagenetic faciesis established by diagenetic,physical and pore parameters,and the differences in characteristics of different diagenetic facies are described.The study shows that the study area belongs to ultra-low porosity and ultra-low permeability oilfield mainly composed of lithic quartz sandstone and quartz sandstone.The qualitative characteristics of diagenesis indicate that the study area is mainly in the middle diagenetic stage B.Mechanical compaction is the main controlling factor for reservoir densification under a series of diagenetic evolutions such as compaction-early cementation-dissolution-late cementation.Four types of diagenetic faciescan be classified according to the diagenetic parameters.The moderate compaction,quartz weakening,intergranular pore,and dissolution pore facies are distributing in the middle of the diversion channel,belonging to high-quality diagenetic facies.Followed by the moderate compaction,moderate kaolinite cementation,dissolution phase,and intercrystalline hole.The mechanism of ultra-low porosity in study area has been clarified and it can provide a reference for advanced description of micro-pore of Sulige Gas Field.
