摘要： A subterranean well cementing slurry is prepared by coating particles of an expanding agent with silica, and combining the coated particles with water and hydraulic cement in any order. The slurry is placed around a tubular member in an annular region in the well where it is allowed to set and harden, and at least some of the expansion is delayed until after the cement is at least partially set.

摘要： Fluid compositions comprising rigid fibers, flexible fibers and solid plugging particles may effectively control the egress of fluids from a subterranean wellbore into vugs, cracks and fissures in the subterranean formation rock. The compositions may be effective in drilling fluids, cement slurries, gravel packing fluids, acidizing fluids and hydraulic fracturing fluids. Such fluids may also have utility for providing fluid diversion during well stimulation treatments, allowing the stimulation fluid to avoid higher permeability regions in the formation rock and treat the lower permeability regions, thereby improving stimulation results.

摘要： A well cementing slurry uses expanding agent encapsulated in a phenolic resin coating. Cement slurries and systems contain water, hydraulic cement, and the encapsulated expanding agent. Cement slurry preparation methods involve coating expanding agent particles with a phenolic resin. Pre-stressed cementing methods involve preparing the cement slurry, placing the slurry in an annulus in the well, hardening the cement, and delaying expansion of the set cement.

摘要： Methods for cementing a subterranean well and maintaining zonal isolation involve preparing a cement slurry that contains water, an inorganic cement and an expanding agent. The slurry is placed in the annular region between casing and the formation or between two casing strings. After the cement sets, the expanding agent reacts and causes the set cement to be in a state of compression within the annular region. The casing dimensions may fluctuate in response to a temperature change, a pressure change, a mechanical disturbance resulting from a well intervention, or mud contamination or a combination thereof. The expanding agent may further react and maintain a state of compression within the annular region. The state of compression in the annular region may be monitored by acoustic impedance measurements.
