Abstract

Considering the geometric configuration of the bottom water reservoir and the contact mode between the bottom water and reservoir, a visualization water drive experiment method for simulating the influence of the seepage barrier in the bottom water reservoir is established. For bottom water drive reservoirs with different positions and properties of seepage barrier, oil and water movement paths are visually observed, also the mechanism and law of water displacing oil are studied. The results indicate that the bottom water reservoir affected by seepage barriers has seepage mechanisms including bottom water coning, bypass flow, and oil water contact uplift. Bottom water coning occurs if without encountering the seepage barrier. If there is a seepage barrier, a bypass flow of bottom water happens, forming residual oil around the seepage barrier. When the seepage barrier is located in the middle of the oil layer on the plane and at the bottom of the oil layer in the vertical direction, the water-cut rises slowly and the water drive effect is good. For seepage barriers with partial permeability, the development effect is better. This study lays a theoretical foundation for analyzing residual oil distribution law and drawing up development adjustment treatments in bottom water reservoirs.
