摘　　要：以岩心、测井资料为基础,通过对沉积相各种标志的分析,认为陕北松新区长6储层属三角洲沉积体系,长61为三角洲平原沉积,长62为三角洲前缘沉积。探讨了沉积特征与油气分布的关系,认为该区三角洲平原分流河道和三角洲前缘水下分流河道砂体是本区主要含油砂体。控油规律分析表明,沉积相对该区油藏的形成和油水分布具有一定的控制作用。Based on core rock,logging,combined with analysis of reservoir lithology and sedimentary characteristics,it indicateas that Chang 6 reservoir in Songxin area in the north of Shaanxi province belongs to delta sedimentary system, Chang 61 is delta plain facies,Chang 62 is delta front facies.The discussion of relationship between sedimentary characteristics and oil distribution found that the distributary channel of plain-delta and underwater distributary channel are the oil sandstone.It can be found that sedimentary facies in the study area have significant effects on oil distribution.
