大庆油田S区块调剖体系方案优化设计研究

Optimization design of profile control system in S block of Daqing Oilfield

根据大庆油田S区块的特征,利用物理模拟实验确定了调剖体系配方及段塞组合,最佳调剖体系配方为JLJ-2与悬浮颗粒体系,段塞组合为五三段塞。在物理模拟的基础上,利用数值模拟软件,应用数值模拟方法优化深度调剖剂的用量、调剖时机、段塞组合等重要参数,给出深度调剖区块整体动态方案。

According to the characteristics of S block in Daqing oil field, the formula of profile control system and slug combination were determined by physical simulation experiment. The best formula of the profile control system was JLJ-2 and the suspended particle system, and the slug combination was 5 and 3 segments. Based on the physical simulation, using numerical simulation software, the numerical simulation method is used to optimize the parameters of the depth profile control agent, such as the dosage of the profile control agent, the timing of pro- file control and the slug combination. We gave the depth profile control block dynamic scheme.
