摘要： A high alumina wellbore cementing composition is provided, the composition comprising:a) high alumina cement; andb) a polyacrylic acid phosphinate having a molecular weight of about 3800 in an amount effective to prevent gelation of the cementing composition for a time period of at least three hours.This composition can remain pumpable for a time period sufficiently long to place the cement in a wellbore using conventional wellbore cementing procedures, and, after the composition is cured, is capable of withstanding elevated wellbore temperatures.

摘要： A wellbore is drilled utilizing an oil-in-water emulsion drilling fluid, optionally containing blast furnace slag. A compatible cementitious slurry containing blast furnace slag and an activator system is then introduced into the borehole and displaced up into an annulus. Generally, the cementitious slurry is prepared by adding additional blast furnace slag and an activator such as a sodium hydroxide/sodium carbonate mixture to the used drilling fluid.

摘要： The present invention is a method to cement a wellbore in the presence of carbon dioxide, or when the wellbore will subsequently be exposed to carbon dioxide. The wellbore is cemented using a blast furnace slag cement slurry, and the resulting set cement is considerably less susceptible to degradation by carbon dioxide.

摘要： A drilling fluid is diluted and a cementitious component added thereto. In a more specific embodiment the dilution is carried out by introducing liquid such as water to a flowing stream of the drilling fluid and thereafter a cementitious component is mixed therewith. Thus, the drilling fluid can be used in a conventional manner to drill a well and thereafter diluted and a cementitious component added to produce a cement for cementing operations such as setting a casing in the well and/or can be used for remedial cementing.In another embodiment of the invention, the drilling fluid itself contains a small amount of cementitious component and additional cementitious component is added after the dilution.
