摘要
依据岩心、测井资料 ,采用 T-R旋回划分方法在牛心坨地区下第三系沙四段牛心坨油层识别出 8个T-R旋回 ,建立起该区的层序地层格架。在此基础上开展全区地层对比 ,指出沙四段牛心坨油层总体上是水体加深的沉积序列 ,其有利的含油气层段是层序 , 和 。
Based on the core and well logging data, 8 transgressive regressive(T R) cycles are identified by using cyclical division in Es 4 of Niuxintuo reservoir, and a sequence stratigraphic framework is established in this area Furthermore, a stratigraphic comparison is carried out in the region, which indicates that Niuxintuo reservoir is a water deepened depositional succession and the favorable oil bearing intervals are sequence VI, V and IV
