摘要: A method for producing an epoxy polyetherpolyol having 15 to 75 wt % epoxy comprising heating a polyol and catalyst to initiate condensation, removing water, introducing sufficient epoxy into the reaction mixture to give 15 to 75 wt % epoxy in the product. Generally, between 0.5 and 1.19 moles of water per mole of polyol are removed. In one embodiment at least 95 wt % of all of the polyol is introduced initially into the reaction zone. In another embodiment the condensation is terminated prior to 93 percent completion. Also provided are novel compositions suitable for drilling fluids, adhesives and coatings.

摘要: Drilling fluid is solidified by the incorporation therein of low grade blast furnace slag. In a preferred embodiment lime is also incorporated into said drilling fluid and/or said drilling fluid is a lime drilling fluid. Thus, there is provided a cementitious composition comprising drilling fluid, low grade blast furnace slag and, generally, lime. Also provided is a drilling and cementing process wherein a cementitious slurry comprising low grade blast furnace slag is introduced into a wellbore to cement a casing or liner.

摘要: A method to determine the amount of blast furnace slag in a slurry sample. The slurry is preferably a drilling fluid or a wellbore cement slurry. The method comprises correlating the amount of hydrogen sulfide released from acidified slurries with the amount of blast furnace slag in the slurry and acidifying the sample and determining the amount of hydrogen sulfide released from the acidified sample.

摘要: A method is provided to determine the concentration of an amorphous material such as blast furnace slag in a slurry such as drilling fluid, completion fluid fluids. A sample is annealed at a temperature between about 800.degree. C. and about 1000.degree. C. for a time period of about six hours to form crystals from the amorphous material, and the sample along with a known amount of a standard is then analyzed by X-ray diffraction. This method is particularly useful in determining the amount of blast furnace slag in a drilling fluid prior to conversion of the drilling fluid to a wellbore cement slurry by addition of additional blast furnace slag.
