摘要: Drilling fluid is solidified by the incorporation therein of coal 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, coal slag and, generally, lime.

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 cementitious slurry is prepared from drilling fluid, blast furnace slag and an emulsion comprising an oil external phase and an aqueous internal phase having therein a additive for said cementitious slurry. In a preferred embodiment the additive is an accelerator for the blast furnace slag such as sodium hydroxide. This allows mixing the additive with the drilling fluid and blast furnace slag without immediate contact between the additive and the other ingredients. After the cementitious slurry has been mixed and pumped into position in a wellbore, the emulsion breaks and the additives are released.

摘要: A slim hole well is drilled using a drilling fluid comprising blast furnace slag and water which drilling fluid is circulated during the drilling to lay down a filter cake. Thereafter, an activator is added and generally, an alkaline material and additional blast furnace slag, to produce a cementitious slurry which is passed down a casing and up into an annulus to effect primary cementing.

摘要: An extended reach well such as the deviated wells typically drilled from offshore platforms is drilled using a drilling fluid comprising blast furnace slag and water which drilling fluid is circulated during the drilling to lay down a filter cake. Thereafter, an activator is added and generally, an alkaline material and additional blast furnace slag, to produce a cementitious slurry which is passed down a casing and up into an annulus to effect primary cementing.
