Abstract

Steam assisted gravity drainage (SAGD) is an advanced technology for the exploitation of super heavy oil reservoir, possessing high oil displacement efficiency and high recovery ratio. The reservoir exploitation threshold standards of SAGD depend on the combined effect of reservoir parameters, technological conditions and oil prize. Other countries have given the SAGD reservoir exploitation threshold according to their own reservoir thickness, oil viscosity and exploitation conditions, but there is no reasonable threshold standards for China to conduct SAGD deployment and efficient exploitation under different reservoir conditions. In this paper, the effect of key reservoir parameters on SAGD exploitation is studied using reservoir numerical simulation technologies. On that basis, the main controlling factors of reservoir exploitation effect in terms of net profit using SAGD with dual-horizontal wells is determined through orthogonal design and multi-index analysis. Finally, the threshold standards of reservoir exploitation using SAGD under different crude oil prices are obtained under existing technological conditions.

Key words： dual-horizontal wells; SAGD; orthogonal design; threshold standards
