Hydrocarbon accumulation was closely related to the local sealing conditions. This study starts with the structural and stratigraphic characteristics of the Caotai buried hill, combines with logging and oil property data, and concludes after the multidisciplinary analysis the seal types. According to the drilled wells in the study area, the sealing styles mainly include petrophysical seal, dike seal, fault seal, and high pour-point oil self-seal. On the basis of this study, many progressive exploration wells have been arranged in this area and verified a promising result. The determined traps are 5.6 km2 in area, and the projected oil in place is 1 200×104 t.
