Yanyeping 1 well cementing technology in Yanchang oilfield

In order to ensure the smooth cementing construction and quality of Yanyeping 1 well,we carried out the static formation pressure test,optimized wells drilling tool structure,applied four grade oil type flushing spacer fluid technology,used special cleaning device,optimized cement slurry system,which effectively solve the problems as the well cementing leakage loss,safely down into the casing,difficulty of removing borehole wall oil film and horizontal cementing,finally to make the cementing well.Cementing reaches best quality.The successful implementation of well cementing technology for shale gas provides a very good reference for the future cementing.
