摘要： Methods of controlling the rates of release of chemical additives into treating fluids are provided by the present invention. The methods are basically comprised of causing a chemical additive in liquid form to be absorbed into a porous solid material whereby the chemical additive is encapsulated thereby and when the resulting encapsulated chemical additive is combined with the treating fluid, the chemical additive is slowly released into the treating fluid. After being encapsulated, the liquid chemical additive is combined with the treating fluid and the treating fluid containing the encapsulated chemical additive is introduced into a well.

摘要： A slurry container for use in a consistometer to test a cement slurry includes a cup and a sealed pressure communicating structure. The sealed pressure communicating structure includes a baffle plate, a thermocouple well threadedly connected to an internal surface of a neck portion of the baffle plate, and a diaphragm extending radially between an outer surface of the neck portion of the baffle plate and an inner surface of the cup and longitudinally between facing surfaces of the baffle plate and a flange of the thermocouple well. A paddle is mounted on a shaft which is pivoted between the lower end of the thermocouple well and the bottom of the cavity defined in the cup. Magnets are mounted on the paddle to provide magnetic coupling across the sealed boundary defined by the baffle plate, thermocouple well and diaphragm assembly.
