Abstract
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
