【摘要】 研究区位于阿姆河盆地右岸,卡洛夫-牛津阶碳酸盐岩为阿姆河盆地的主要产气层,自上而下可划分GAP层、XVhp层(礁上层)、XVa1层、Z层、XVa2层、XVI层,本文主要对该区域上侏罗统卡洛夫-牛津阶的XVhp层进行研究,探讨土库曼斯坦B区卡洛夫—牛津阶XVhp层沉积相特征。以岩心观察、薄片和古生物鉴定为研究依据,对研究区内10口井的岩石学特征,古生物特征,测井相和地震相特征进行分析研究,通过以上研究并结合连井剖面对比、沉积相平面分布特征,总结出XVhp层主要发育为前缘缓斜坡相,沉积亚相包括上斜坡亚相、点礁亚相、下斜坡相。更多还原

【Abstract】 The study area is located in the right bank of the Amu Darya basin. The natural gas is mainly produced in Callovian-Oxfordan sedimentary facies in Amu Darya basin,from top to bottom it can be divided into GAP layer,XVhp layer,XVa1 layer,Z layer,XVa2 layer nd XVI layer. the XVhp plane distribution of Callovian-Oxfordan sedimentary facies was explored. The sedimentary characteristics XVhp plane distribution of Callovian-Oxfordan was investigated. Based on core observations,identification of thin sections an paleontology,in combination with Petrology Characteristics,stratigraphy,logging facies and seismic faces,Combined with well profile and vertical evolution of sedimentary facies,it is concluded that XVhp layer are mainly developed type of foreslope facies,subfacies including slope facies,sub facies,reef point under the slope facies.更多还原
