摘要
综合运用微观薄片、岩芯、录井、测井等资料,总结了四扣洼陷西部地区沙四上亚段湖相碳酸盐岩的沉积特征,并根据古地貌特点建立了与之相应的湖相碳酸盐岩沉积模式。研究认为在洼陷缓坡带主要发育灰泥坪、岸滩、滩间和浅滩-藻礁沉积微相,而在洼陷陡坡带则主要发育灰泥坪、岸滩-藻礁沉积微相。
Based on the data of thin slice, drilling core, logging and log ,sedimentary c lacustrine carbonate rock of up Sha 4 member in Sikou sag have been analysed. According omorphology of up Sha 4 member,the depositional model of lacustrine carbonate rock has b are lime--mud flat,shore beach ,interbeach and shallow beach--algal reef in the gentle s and there are lime--mud flat, shore beach--algal reef in the abrupt slope of the sag.
