商河油田商三区、商四区以低渗透油藏为主,目前处于开发中晚期,受低渗透油藏本身特征和井网二次不完善影响,开发矛盾突出。本文通过对该区油藏注水规律和剩余油分布的深入研究,从而指导下步高效开发。 Shangsan Oilfield Shangsan District, Shangsai District are mainly low permeability reservoirs, and are currently in the middle and late stages of development. Due to the characteristics of low permeability reservoirs and the imperfections in well patterns, the contradictions in development are prominent. In this paper, through deep research on the law of waterflooding and the distribution of remaining oil in this area, we can guide the next step of efficient development.
