A Modified Cement Slurry Prepared with Compound Material

A cement slurry prepared with compound materials(latex,fiber and elastic particles)was developed.Laboratory evaluation showed that the slurry had a good rheology,a low fluid loss,zero free water,a straight consistency profile and an adjustable thickening time.Set cement of this cement slurry had a stable performance in corrosion environment,and had a higher strength against shock stresses,and deformation.Good performance of the slurry both at fluid and solid states satisfied the requirement imposed by cement job and downhole conditions,Gas-channeling can be avoided during cement setting and after set.
