摘要
Based on core observations, identification of thin sections and paleontology, in combination with logging facies, seismic faces and regional depositional background, the authors reached the conclusion that Callovian-Oxfordian carbonates in Amu Darya basin of Turkmenistan are carbonate platform deposits. According to the facies correlation sections of the wells as well as the plane distribution and vertical evolution of sedimentary facies, the authors revealed the evolution characteristics of Callovian-Oxfordian sedimentary facies. Finally, the depositional model of “platform with open, rimmed and gently dipping slope” was established.
