  • In commenting the long, low temperature wellbore with shallow gases in Daqing, the low density cementing slurries used had long final setting time, slowly developing gel strengths, high filter loss, and poor anti-channeling performance. All these factors contributed to channeling in annular spaces and bubbling outside the casing string, indicators of poor cementing job. In studying the low density low temperature anti-channeling cement slurry, the cement slurry was treated with a compound early strength agent, a polyacrylate filter loss reducer and a dispersible polymer anti-channeling agent, all being used to improve the overall performance of the slurry. At low temperatures, the setting time was shortened by 50%, the early strength increased by 46%, permeability reduced by 50%, and the bond strength of the interface enhanced by 47%. The cement slurry formulation has been used in 18 wells, and 11.1%of the cementing jobs were of excellent quality, bubbling outside the casing string was reduced by 1.6%. The use of the low density low temperature anti-channeling cement slurry improved the quality of the cementing jobs.
