摘要:
Cement compositions and methods of cementing within subterranean formations penetrated by well bores wherein the flow properties of one or more dry particulate cementitious materials are improved and wherein the materials can be readily conveyed out of storage tanks and the like. A preferred composition of the present invention comprises a particulate flow enhancing additive dry-blended with one or more dry particulate cementitious materials, said flow enhancing additive being comprised of a particulate solid material carrying a flow inducing polar chemical, and a sufficient amount of water to form a pumpable slurry. The methods basically include the steps of dry-blending the particulate flow enhancing additive with the one or more dry particulate cementitious materials; forming a pumpable slurry using the one or more cementitious materials having the particulate flow enhancing additive blended therewith; pumping the slurry into a well bore; and then allowing the slurry to solidify within the subterranean formation.

摘要:
Submerged cavities such as occur in jacketed pilings in offshore structures are grouted by the sequential use of materials with initially decreasing densities, the heaviest of which is lighter than water, followed by the use of conventional grouting materials of greater density. The first material is quick setting and generally water-immiscible. Water is thus displaced downwardly out of the cavity by the lighter material. The first material is forced to the bottom of the cavity and allowed to set as a plug to support the conventional grouting materials.
