New cement slurry for deep wells casing

摘要

New cement slurry compositions stabilized with synergetic mixture of reagents are investigated. It is found that the addition of these reagents provides the considerable water loss decrease and cement slurry retarding at satisfactory durability of cement stone. The new cement slurry has been tested successfully at cementing the first section of casing column in the 14-Kobzivska well under high bottom-hole temperature and pressure.
