Study On Cementing Technology Of Lost Circulation Well In Northeast Sichuan

In order to change the condition of slurry while well completion and cementing,and analyse the Potential reason to conduct new technology research in Northeastern Sichuan Province,we complete We completed the innovations as follows: choose sealing materials,research and analyse the buffer liquid and cement slurry for sealing,improve the slurry leaking efficiency; invent and develop new light pressure material,slove the problem of breaking of traditional material in high pressure,reduce the cost of production during well cementing.Through the detailed research of leak protection and well cementation,the whole construction technology eventually come into a complete set of technology of this field.The technology reduces the seepage loss and improve the quality of construction while the well cementation.
