塔河油田三叠系阿四段是近年来开发的重点层系，阿四段沉积类型及砂体展布和储层非均质性对流体分布的影响倍受重视。通过对区域沉积环境分析，在岩心描述和测井分析基础上，结合铸体薄片、粒度分析等大量测试资料，对塔河油田2区三叠系阿四段出油砂体沉积类型及沉积特征进行深入研究。结果表明，塔河油田2区三叠系阿四段出油砂体为滨浅湖沉积环境下的滩坝砂。据砂体形态和产状可分为滩砂和坝砂两种，其中，坝砂为研究区有利储层。

4th member of Triassic Akekule Formation in 2nd Area of Tahe Oilfield is founded important layer in recent years,of which the sedimentary type,sand body distribution,reservoir control and other kinds of geological issues are paid much attention to. Based on regional depositional environment,core description and logging analysis,combined with castthin section and grain size analysis,the sedimentary facies and characteristics are studied.The result shows that 4th yield oil sand body of Triassic Akekule Formation in 2nd Area of Tahe Oilfield belongs to beach-bar sand deposition-al environments of the littoral and shallow lake. According to sand body morphology and occurrence,Beach-bar sand can be divided into beach sand and bar sand,and thus,by analysis of the sand body distribution,reservoir properties, bar sand is favorable reservoir.
