摘要
为了有效抑制红南油田边底水的锥进速度,进一步提高采收率,以油藏工程理论为指导,以物理模拟为技术手段,以红南典型物理模型为实验平台,开展了边底水油藏提高采收率方法实验研究。结果表明:边底水油藏采用注水开发方式时,通过适当增加注入压力可以提高采收率;与聚合物溶液相比较,水和表面活性剂提高注入压力后,采收率增幅较大;油井实施底水封堵后可以改善水驱开发效果。
In order to effectively inhibit the bottom and edge water coning speed and further enhance the recovery of Hongnan Oilfield, guided by the reservoir engineering theory and with the help of the physical simulation, the experimental studies on the EOR methods for the reservoirs are conducted by means of the testing platform of Hongnan typical physical model. The achievements show that for the bottom and edge water oil reservoir, the properly increased water injection pressure can enhance the oil recovery; comparing with the polymer solution, the oil recoveries of the water and surfactant are greatly enhanced after the injection pressure increase; after simulating the bottom plugging for the oil producers, the water flooding effects can be improved.
