【摘要】：针对三塘湖盆地牛圈湖油田西山窑组油藏岩性横向变化快,沉积微相控藏明显的特点,基于油田上产急需精细沉积微相支持的现状,综合运用岩心、录井、测井、地震、岩石薄片等资料,对牛圈湖油田西山窑Ⅱ砂组沉积微相进行了精细研究。研究认为:牛圈湖油田西山窑Ⅱ砂组主要发育辫状河三角洲前缘亚相,次为前辫状河三角洲亚相。研究区的南缘较陡,发育冲积扇、辫状河三角洲及湖泊等沉积体系,在坡度较缓的北缘发育辫状河三角洲直接入湖的沉积体系。通过地震资料、薄片鉴定及重矿物分析,认为储层砂体由南北物源控制,且东区具有以南部物源为主的特点,而并非前人认识的以北部物源为主。在东北、西北和南部划分出3个优势储层区,其可作为下一步勘探开发的目标区。
