Title: Application of continuous sealing core drilling technique on Well Niuye 1
Abstract: In the development design for Well Niuye 1,it is required to conduct long-section continuous sealing core drilling.The coring formations are lower Sha-3 and lower Sha-4,and the coring footage is 225 m,so the coring difficulty is great.Through selecting sealing coring tool,coring bit,screening proper coring fluid,and optimizing drilling parameters,the yield of 90.46% is obtained.The success application of continuous sealing core drilling technique on Well Niuye 1 plays an important role in getting aware of the reservoir characteristics and oil saturation of Niuye 1 Zone in Niuzhuang-Liuhu Depression.It supplies reference for conducting continuous sealing core drilling in the same kind of formation.
