【摘要】 在总结前人工作的基础上,结合作者对塔里木盆地和四川盆地碳酸盐岩的研究,根据地理位置、坡度、封闭性和镶边性把碳酸盐岩台地分为以下类型:缓坡开放型无镶边台地、缓坡封闭型无镶边台地、陡坡开放型无镶边台地、陡坡封闭型无镶边台地、缓坡开放型有镶边台地、缓坡封闭型有镶边台地、陡坡开放型有镶边台地、陡坡封闭型有镶边台地、礁滩型孤立台地、岩隆型孤立台地。总结了不同类型碳酸盐岩台地沉积特征并建立了沉积模式,用以指导当前碳酸盐岩的油气勘探。最后,探讨了不同类型台地形成和发育的主控因素,认为构造运动所形成的古地形(貌)和水体能量控制台地和沉积物的类型,海平面的升降控制台地类型及沉积物的变化。更多还原

【Abstract】 Analyses of the carbonate platform have been carried out based on the achievements of previous researchers,combining with the author’s studies of the carbonate platforms in the Tarim Basin and Sichuan Basin.The carbonate platform is divided into the following types according to geographical position,slope gradient,sealability of platform margin and rimming feature of platform,namely as:the gentle slope and open platform without rims,the gentle slope and restricted platform without rims,the steep slope and open platform without rims,the steep slope and restricted platform without rims,the gentle slope and open platform with rims,the gentle slope and restricted platform with rims,the steep slope and open platform with rims,the steep slope and restricted platform with rims,the reef-bank isolated platform and the buildup isolated platform.The sedimentary characteristics of different types of platforms were investigated and their sedimentary models were established which can guide the hydrocarbon exploration of carbonate rocks.Finally,the main factors controlling the formation and development of carbonate platforms are discussed.The reseaarch indicates that paleotopography formed by tectonic movement and the water flow energy control the types of the platform and sediments and the sea level changes control the types of platform and the changes of sediments.更多还原
