Research and Application of Foam Plugging in Horizontal Wells Steam Flooding of Offshore Oilfield
摘要
Abstract
Foam plugging can improve steam profile and expand steam sweeping area,which is an effective measure to improve the development effect of steam flooding.In view of the characteristics of steam flooding of N Oilfield in Bohai,such as complex offshore environment,high operation and construction risk,and difficulty in plugging for horizontal wells with large spacing,the research on foam plugging for steam flooding in offshore horizontal wells with large well spacing was carried out.The key performance indexes of high temperature resistant foaming agent were evaluated through laboratory experiments.The RFA-1 foaming agent can withstand temperature up to 350 ℃,and the resistance factor can reach 44 in high temperature environment,which has good plugging and adjusting performance.The field tests verified the effectiveness of foam plugging to improve the development effect of steam flooding.Foam plugging can effectively control water and improve steam profile.In application,the water cut of the cross-flow well decreased significantly from 81.7％to 47.0％,and the oil was increased by about 800 t.关键词
