摘　　要：本文通过对靖边油田乔家洼油区延长组长6段油藏的地质特征、成藏机理及沉积相与油气关系进行分析研究。结果表明:本区延长组长6油藏为特低孔-特低渗-微细喉-低饱和-层状-岩性油藏,指出储层特征、沉积相带与油气富集程度密切相关,分流河道砂岩主体带是油藏形成的有利场所。成藏规律研究认为,该区东西方向成藏条件差,南北方向储层物性好,为近期勘探开发的有利目标区。According to the geological features of Chang-6 oil reservoir of Yanchang formation,and pool-forming mechanism and sedimentary facies and the relationship between oil and gas are analytical studied in Qiaojiawa area of lingbian oilfield.research.The results show that：the Chang-6 oil reservoir of Yanchang formation-ultra-low-hole-Low permeability-tiny throat-low saturation-layered - lithologic reservoir,pointed out that the reservoir characteristics,the sedimentary facies belt of oil and gas is closely related to the degree of enrichment,distributary channel with the main sandstone belt is the reservoir formed by a favorable place.Study accumulation of the view that the area west-east direction reservoir condition is poor,the north and south direction reservoir nature is good,exploration and development in the near future for the benefit of the target area.
