摘要： 随着准噶尔盆地油气勘探的不断深入,岩性圈闭的勘探将成为今后的工作重点和难点。如何对岩性圈闭进行识别、预测和描述,是石油地质工作者现在和今后所要面临和解决的问题。针对夏子街地区A67井区运用层序地层学理论,结合钻井资料,配合沉积相研究,在目标区对地层进行对比和小层划分,选取目标砂体,利用沿层属性提取、地震相等多种先进的地球物理技术,准确地识别出A67井区克拉玛依下亚组的多个扇体,为识别该区岩性圈闭总结出了一套行之有效的方法。

Abstract: With the continuous petroleum exploration in Junggar basin, lithologic trap's exploration becomes the focal point of work in the days to come. How to make an identification, prediction and description of the lithologic traps is a problem to be urgently solved. This paper presents the studies of A67 Wellblock in Xiazijie area as a target zone using sequence stratigraphy theory, integrated with the drilling data and sedimentary facies analysis, including formation correlation, layer division, sand body selection, seismic attribute extraction and seismic facies identification, etc. The study indicates that there exist several sand bodies in Lower Karamay formation of A67 Wellblock. This provides an effective method for identification of the lithologic traps in this area.

Key words: Junggar basin, Triassic, Lower Karamay formation, formation correlation, seismic attribute, sedimentary facies, sand body
