A THIXOTROPIC FLUID FOR WELL INSULATION |
摘要 |
A thixotropic thermal insulating fluid includes a heavy hydrocarbon, water and oleophilic clay, wherein said heavy hydrocarbon is present in an amount of between about 75% to about 92% by volume of the fluid, said water is present in an amount of between about 5% to about 15% by volume of the fluid, and said oleophilic clay is present in an amount of between about 3% to about 10% by volume of the fluid. The fluid may be prepared by mixing water in an amount of between about 5% to about 15% by total volume of the fluid with oleophilic clay in an amount of between about 3% to about 10% by total volume of the fluid so as to provide a substantially homogeneous mixture; and mixing said mixture with a heavy hydrocarbon in an amount of between about 75% to about 92% by total volume of the fluid under agitation for a time sufficient to provide a thixotropic gel.
