| 摘 要： | 通过沉积相和层序地层分析，确定土库曼斯坦阿姆河盆地中-上侏罗统卡洛夫-牛津阶主要为一套碳酸盐岩台地沉积体系，可划分出SQ1～SQ3三个三级层序，经历了从缓斜坡台地→镶边缓斜坡台地→缓斜坡台地的沉积演化过程，主力储、产层发育于SQ1和SQ2层序，此三个层序又可进一步划分为TST和HST两个体系域。以体系域为编图单元，编制了SQ1、SQ2和SQ3层序各体系域的岩相古地理图和探讨了有利储集相带展布规律，认为SQ1-HST、SQ2-TST和SQ2-HST三个体系域中叠置发育的台缘礁滩为最有利储层发育的相带，应成为今后的勘探重点。

| Abstract: | The analysis of the sedimentary facies and sequence stratigraphy suggests that the Callovian-Oxfordian stage of middle-upper Jurassic of the Amu Darya basin in Turkmenistan is a sedimentary system consisting of carbonate platforms. From this system, three third-order sequences (SQ1-SQ3) can be recognized, which have experienced the sedimentary evolution from the slope ramp to the rimmed ramp, and finally to the slope ramp. The main reservoirs and producing layers developed in the SQ1-SQ2, which can be further divided into transgressive systems tract (TST) and Highstand Systems Tract (HST). Taking the system tract as the mapping unit, the lithofacies palaeogeography maps for each tract system in SQ1-SQ3 are prepared. In light of the distribution of favorable reservoirs, the superimposed platform margin reef-bank facies in the HST of SQ1, TST of SQ2, and HST of SQ2 are considered to be the key areas in the future exploration. |
