摘要
针对王庄油田郑408块强水敏稠油油藏常规注水效果差的问题,在储层敏感性评价和油层保护研究的基础上,优选出了适合强水敏油藏的防膨剂,成功实现了注防膨水开发。现场应用后区块开发效果得到改善,有效地补充了地层能量,提高了油井产能,区块产油量由25t/d上升到59t/d。该试验的成功对水敏油藏开发具有指导意义。
The effect of conventional water injection was poor in strong-water-sensitivity heavy oil reservoir of Zheng 408 block in Wangzhuang Oilfield.On the basis of res-ervoir sensitivity evaluation and formation protection study,an anti-swelling agent has been selected for strong-water-sensitivity reservoir and successfully applied in anti-swelling water injection development. Production result of the block has been improved after field application.The formation energy has been sup-plemented effectively and oil well productivity has in-creased.Oil production of the block increased from 25t/d to 59t/d.The success of the experiment has guiding significance on the development of the water-sensitive oil reservoirs.
