中文摘要：

冀中坳陷深县凹陷东营组砂岩储层岩石类型以长石岩屑砂岩或岩屑长石砂岩为主,岩石成分成熟度和结构成熟度均较低,反映了近物源和多物源的特征。通过对研究区的岩心化验分析资料、薄片和扫描电镜资料的分析,认为深县凹陷东营组储集空间类型主要包括原生孔隙和次生孔隙两类,其中以原生的粒间孔隙为主。研究区岩性孔渗资料的统计结果表明,储层的物性较好,基本为中高孔中渗型储层,根据深县凹陷储层评价标准,可以将深县凹陷储层分为4类,东营组储层主要是Ⅰ类和Ⅱ类储层。深县凹陷东营组主要为辫状河流相沉积,其沉积作用直接决定着储集砂体的类型、展布范围以及后期成岩改造作用。而储层储集性能主要受原始沉积作用及后期成岩作用共同控制,控制储层孔隙演化的成岩作用主要为机械压实作用和胶结作用。

英文摘要：

The sandstone reservoir of the Dongying Formation in the Shenxian Depression,Jizhong Sub-basin is primarily composed of feldspathic lithic sandstone and lithic sandstone of low maturity.This means that the deposits come from multiple provenances and are close to the provenances.According to the conventional core analysis data,thin sections and scanning electron microscopic（SEM）data,the main pore types of the reservoir include primary and secondary pores,of which the primary intergranular pores dominate.The porosity and permeability data in the study area shows that the reservoir mainly belongs to a kind of high-porosity and mid-permeability.According to the standard for reservoir evaluation in the Shenxian Depression,there are four types of reservoirs,and the reservoirs of Dongying Formation are mainly of typeⅠ and typeⅡ.The Dongying Formation in the Shenxian Depression is mainly a braided stream facies,which is the key factor controlling the reservoirs sand types,distribution pattern and later stage diagenetic reconstruction.The properties of the reservoirs are controlled by both the processes of deposition and diagenesis.The reservoirs have undergone three types of diagenesis,i.e.mechanic compaction,cementation and dissolution,and the former two are the main factors controlling the pore evolution.
