Development technology for thin water-sensitive ultra heavy oil reservoirs in Zheng14 Block of Wangzhuang Oilfield

The development result of s3up reservoir in Wangzhang Oilfield has been poor for many years because of heavy oil,strongly water-sensitive and poor initial sand control of open hole completion.Comprehensive study on geology,thermal recovery adaptability,reservoir protection,reservoir engineering and supporting techniques has been conducted for this thin,strongly water-sensitive,ultra heavy oil reservoir,and a series of supporting techniques for s3up glutenite heavy oil reservoir has been formed,thus putting an end to the adverse trend of long-term ineffective producing,and providing valuable experience to the development of other similar reservoirs.
