介绍计算注水开发油田稳产期的经验公式 ,并根据公式分析影响稳产期的因素 ,指出油田的稳产年限与稳产期内的年产油量成反比。在稳产期内 ,如果在开发过程中采取投产新井、补孔、压裂等重大调整措施 ,改善油层动用状况 ,增加油田可采储量 ,则可延长油田稳产期。将此技术应用于文中油田的高含水后期开发 ,取得了明显的的稳产效果。
The empirical formula for calculating the stable production period of waterflooding oilfield is introduced. According to the formula, the factors that affect the stable production period are introduced. It is pointed out that the stable production period of oilfield is inversely proportional to the annual oil production during the stable production period. In the stable production period, if the production process in the development of new wells, fill holes, fracturing and other major adjustments to improve the utilization of the reservoir conditions, increase recoverable reserves, you can extend the stable production period. This technology has been applied to Wenchuang Oilfield in the late stage of high water cut, and has achieved obvious stable yield.
