摘要: 本文在综合分析阿克库勒凸起西南缘的托浦台泥盆系的三维地震资料和24口井的录井、测井、岩芯、薄片资料的基础上,将研究区泥盆系划分为包括一个海侵体系域和一个高位体系域的三级层序。海侵体系域主要发育远滨和近滨沉积,高位体系域主要发育近滨和前滨沉积。

Abstract: The Devonian strata in Tuoputai on the southwestern margin of the Akukule uplift,Xinjiang consist of one third-order sequence including one transgressive systems tract and one highstand systems tract based on the integration of the three dimensional seismic data,well logs,cores and thin section examination of the Donghe Sandstones.The transgressive systems tract is built up of the offshore and nearshore deposits while the high-stand systems tract is assembled by the nearshore and foreshore deposits which have provide a locus for the development of hydrocarbon reservoirs and lithologic traps.
