    摘要: A drilling and cementing process wherein a drilling fluid containing a metal compound which is a proton acceptor component is utilized, thereby laying down a filter cake. Thereafter, the drilling fluid can be combined with a phosphorus acid to give a cementitious slurry which is thereafter used in a cementing operation. Alternatively, a phosphorus acid such as polyphosphoric acid is circulated into contact with said filter cake.

    摘要: A cementitious slurry comprising microfine ground blast furnace slag and normally ground blast furnace slag. A microfine ground blast furnace slag is made of composition having a blaine specific surface area between 8,000 and 20,000 cm.sup.2 /g. By normally ground is meant slag compositions having a surface area of less than 8,000 cm.sup.2 /g. Such cementitious compositions have utility in construction, road building, and cementing wellbores.

    摘要: A drilling and cementing process wherein a drilling fluid containing blast furnace slag which serves as a a metal compound which is a proton acceptor component is utilized and thereafter combined with a water-soluble or water-dispersable polymer of the formula ##STR1## wherein A is ##STR2## or a mixture of ##STR3## and, wherein R is hydrogen or 1-10 carbon atom alkyl radical, to give a cementitious slurry which is thereafter used in a cementing operation. The metal oxide source and/or the cementitious component of the cement can be blast furnace slag.
