摘要： 库车坳陷北部下侏罗统阿合组是油气勘探的重要目的层，但是岩相变化快、砂体构型复杂、储层相对致密、非均质性强，制约了油气勘探。通过建立露头基干剖面、横向砂体追踪、砂体构型精细描述、针对性取样和储层实验分析，分析砂体的垂向建造、横向展布规律及不同岩相的储集性能，结果表明：阿合组纵向上有大型砂砾质辫状水道-侧积坝-纵向砂坝、中型砂砾质辫状水道-横向砂坝-滨湖复合砂体、小型砂质辫状水道-斜列砂坝等3种沉积建造。其中中型辫状水道-横向砂坝储集性能相对较优，有利储层主要是槽状交错层理砂质细砾岩、板状交错层理中砂岩和低角度平行层理细砂岩。研究区下辫状河三角洲平原和前缘均是有利勘探方向。

Abstract: Large sand-gravel braided river delta was deposited in the Jurassic Ahe Formation in northern Kuqa Depression of Tarim Basin,which is an important target for oil and gas exploration. However,the rapid change of lithofacies, complex sand body architecture, relatively tight reservoir and strong heterogeneity restrict the exploration and development of oil and gas. Through the establishment of outcrop basal section,transverse sand body tracking,sand body configuration description,sampling and experimental analysis of sandstone with different lithofacies,the vertical construction,transverse distribution regularity and reservoir properties of different lithofacies were analyzed. The results show that there are three types of sedimentary formations formed on the longitudinal of Ahe Formation:large-scale sandy gravel braided channel-lateral accretion bar-longitudinal sand bar,mediumsized sandy gravel braided channel-transverse sand bar-lakeside composite sand body,and small-sized sandy braided channel-inclined sand bar. Among them,the reservoir performance of medium-sized channel-transverse sand bar is relatively better,and the favorable reservoirs are mainly trough cross bedding sandy fine conglomerate, tabular cross bedding medium sandstone and low angle parallel bedding fine sandstone. The lower braided river delta plain and front are favorable exploration directions.

Key words: reservoir characteristics, braided river delta, sand body configuration, Ahe Formation, Jurassic, Kuqa Depression
