摘　　要：针对神木气田太原组建立层序界面识别标志，进行层序地层划分。应用最新生产数据对研究区早二叠世海侵期次和方向精细刻画．通过对4次海侵石灰岩分布范围和厚度的研究，建立岩相古地理演化特征；同时在沉积背景基础上将太原组砂体分为3套砂岩，指出马兰砂岩为主力储层的原因，并指出海侵范围和期次对砂岩发育的影响作用，为神木气田开发指明了方向。A sequence boundary identification mark is established in this paper,in the light of Taiyuan Formation of the Shenmu gasfield,to conduct the sequence stratigraphic division. Applying the latest production data to finely portray the stages and direction of the Early Permian transgression in the study area,the characteristics of litho-facies palaeo-geographical evolution is established through researches of the four transgressive limestone ranges and thickness. Based on the deposition background the Taiyuan Formation sandstone is divided into three sets of sandstone facies. The reasons why the Malan sandstone is the main reservoirs are put forward, and pointed out the effect of the scope and stages of the transgression on the sandstone development.
