摘要
彩南油田三工河组油藏边底水活跃，天然能量较充足，并且油藏与边底水的连通性好、油层渗透率较高、油水粘度比低、导压系数高、边底水补充快，因此，适合于长期利用天然能量开发。文章介绍如何根据不同区块的不同特点，确定合理的注水时机、注水部位及合理的采油速度，最大限度地利用天然能量，以最少的注水井数和注水量来满足高速开发的需要，使整个油藏连续五年以２９％～３４％的采油速度高速开发，实现油田低中含水期稳产和获取较高采收率的目标，取得了较好的经济效益。
Sangonghe reservoir in Cainan oilfield is characterized by active edge and bottom water, abundant natural energy, good connectivity, high permeability, low oil water viscosity ratio and high pressure conductivity coefficient, and quickly replenished edge and bottom water, suitable for a long term development with natural energy. According to characteristics of different blocks, this paper discussed how to determine reasonable water injection timing, position and oil recovery rate in order to maximize the utilization of its natural energy. Sangonghe reservoir was developed with oil recovery rate of 2.9%～3.4% for more than five years, kept stable production of oilfield in low moderate water cut stage and obtained higher oil recovery and better economic benefit.
