土库曼斯坦阿姆河右岸别什肯特坳陷区整体勘探程度较低，地质认识不足。通过岩心、薄片观察以及物性资料和测井解释资料分析，并运用交会图、测井相分析等方法，对卡洛夫—牛津阶灰岩储层展开了岩性、物性、储集空间、储层类型以及储层发育主控因素等研究。结果表明：卡洛夫—牛津阶储层岩石类型以含颗粒泥晶灰岩、泥晶颗粒灰岩为主，微亮晶颗粒灰岩次之；储层物性整体较差，呈现低孔、低渗 和低孔、中渗特征；储集空间以次生溶孔为主，伴有部分微裂缝和少量生物体腔孔；储层类型以孔隙-裂缝型为主；储层发育受沉积作用控制明显，有利储层发育区主要分布于生屑滩、生屑丘以及颗粒丘微相中，少数分布于灰泥丘微相中；溶蚀和构造破裂作用对改善储层物性发挥了重要作用。研究成果可为该区卡洛夫—牛津阶的进一步勘探开发提供参考。

The Bieshikent Depression at the right bank of Amu Darya in Turkmenistan is characterized by low degree of exploration and lack of geologic knowledge. Based on core and thin section observation, combined with the analysis of physical properties and logging interpretation, the methods such as crossplot and electrofacies analysis were applied to study the lithologies, physical properties, reservoir spaces, reservoir types and main controlling factors of reservoir development of limestone reservoir of Callovian-Oxfordian. The results show that the reservoir rocks of Callovian-Oxfordian are mainly composed of micrite limestones and micrite granular limestones, and micro sparite granular limestones come second. The reservoir physical properties are poor, with low porosity and low-medium permeability. The main reservoir spaces are secondary dissolved pores, with some micro fractures and a small amount of biological cavity hole, so it mainly belongs to porous-fracture reservoir. The reservoir development is mainly controlled by sedimentary facies. The favorable reservoirs are mainly developed in microfacies such as bioclastic beach, bioclastic mound and grannular mound, with a little in lime mound. Dissolution and tectonic fracturing improve the reservoir properties. This study results can provide a reference for further exploration and development of Callovian-Oxfordian reservoir.
