摘要
Well Hasheng-X1 is an important risk wildcat in Shengli oilfield,which is a directional well with double targets with high deviation angle,long steady inclined section and large horizontal displacement.As a risk wildcat,there is less drilling data of adjacent wells and there are uncertain factors of formation lithology,formation pressure and layer section variety.It is an important basis to ensure smooth construction to determine reasonable casing program,optimized trajectory,good mud performance parameters and other relevant technical measures.Based on the detail analysis on the very few information,the optimized schemes and technical measures were proposed in well trajectory design,casing program design,bottom hole assembly & drilling method selection,drilling fluid design and cementing design;these above could be the technical support and theoretical basis to the design of the risk wildcat in Shengli oilfield.
