    摘要: The present invention provides set retarding additives, set retarded hydraulic cement compositions and methods of using the set retarded cement compositions for cementing subterranean zones in wells. A preferred set retarding additive comprises an alkanolamine salt produced by the reaction of a hydroxy carboxy acid, such as tartaric acid, gluconic acid or glucoheptonic acid, with an alkanolamine, such as monoethanolamine, diethanolamine or triethanolamine.

    摘要: The present invention provides cementitious well drilling fluids and methods of drilling subterranean well bores. The drilling fluids are basically comprised of water, a water viscosity increasing material and a cementitious material which when deposited on the walls of the well bore as a part of the filter cake thereon consolidates the filter cake into a stable mass that readily bonds to a cementitious material slurry subsequently placed in the well bore. The methods of drilling a subterranean well bore are basically comprised of the steps of preparing a drilling fluid of the invention and drilling a subterranean well bore using the drilling fluid.
