摘要
聚合物驱时注入压力的变化与许多因素有关,它可直接反映注聚效果的好坏。正确分析注聚压力的变化趋势,可适时调整注聚方案,使聚合物得到最佳效果。根据河南油田6个聚合物驱区块83口注聚井的现场资料,研究分析了聚合物注入压力的3种变化趋势,并结合现场的实际处理效果提出了相应对策。
Pressure changes in polymer flooding is related with many factors. by which the efficiency of polymer flooding is directly reflected. Real-time adjustment of the polymer flooding project would be made for an optimal flooding result by correctly analyzing the tendency of pressure changes in the flooding. Based on the field data of 83 wells of 6 injection blocks in Henan Oilfield, 3 tendencies of the polymer flooding pressure changes are analytically studied, thus related countermeasures are proposed in combination with field operation efficiencies.
