摘要/Abstract

摘要： 为了阐明砂质辫状河相储层特征及主控因素，以鄂尔多斯盆地安边地区延10储层为例，综合运用粒度分析、铸体薄片、扫描电子显微镜、压汞法和常规物性分析，并结合岩心和测井资料进行宏观印证。结果表明：安边地区延10储层发育砂质辫状河相，包括河道、心滩和泛滥平原微相。储层岩性以长石石英砂岩和岩屑石英砂岩为主；储集空间主要为残余粒间孔和长石溶孔构成的粒间孔-溶孔组合；可识别中细喉道、微细喉道及微喉道等3种主要喉道类型，孔隙度为11.23%～17.95%，渗透率为5.35～56.57 mD，属于中低孔-低渗特低渗细喉型储层；沉积微相是影响延10储层物性特征的物质因素；破坏性成岩作用为压实作用和黏土矿物、硅质以及钙质的胶结作用，其中压实作用为主要因素；建设性成岩作用主要为长石颗粒及部分胶结物的溶蚀作用，以及绿泥石膜对压实及胶结作用的抑制作用。该研究成果对于辫状河相的有利储层预测具有重要意义。

Abstract: To clarify the characteristics and main controlling factors of sandy braided fluvial reservoir, Yan 10 reservoir in Anbian area of Ordos Basin was comprehensively verified by grain size analysis, cast thin section, scanning electron microscope, mercury injection method and conventional physical property analysis, combined with core and logging data. The results show that sandy braided fluvial facies are developed in Yan 10 reservoir in Anbian area, including channel, central bar and flood plain microfacies. The reservoir lithology is mainly feldspathic quartz sandstone and lithic quartz sandstone, and the reservoir space is mainly composed of residual intergranular pores and feldspar dissolved pores. Three main types of throats can be identified, including meso fine throat, micro fine throat and micro throat. The porosity ranges from 11.23% to 17.95%, and the permeability is generally 5.35-56.57 mD, which belongs to medium-low porosity and low-ultra low permeability fine throat reservoir. Sedimentary microfacies are the material factors that affect the physical properties of Yan 10 reservoir. Compaction and cementation of clay minerals, siliceous and calcareous are destructive diagenesis, among which compaction is the main factor. The dissolution of feldspar particles and some cements and the inhibition of chlorite film on compaction and cementation are constructive diagenesis. The research results are of great significance for the prediction of favorable reservoirs in braided river facies.
