Zhengwen Li · Oil Drilling & Production Technology · 2009
District 1 of Chenghai of Dagang Oilfield lies in the beach sea of the coast of Bohai bay.Matching technologies of drilling and completion technology in Chenghai was introduced.Among them,program design and optimization of extended-reach horizontal wells,well track optimization of cluster well and slot wellhead,hole cleaning and stability technology,casing running completion was briefly presented.The matching technologies of Chenghai were of high practicability,strong operability and supplied successful experience.They gave good examples of developing marginal oil fields by extended-reach horizontal wells and exploiting block oil fields.The extended-reach horizontal well technology was proved to have broad application prospects.
