VISCOSIFIED ACID FLUID AND METHOD FOR USE THEREOF |
| 摘要 |
A method includes providing an oilfield treatment fluid including an aqueous HCl solution having greater than 15% HCl by weight, and a fixing agent (FA) in a molar ratio of FA:HCl of between 0.5 and 2.5 inclusive. The FA is urea and/or a urea derivative. The oilfield treatment fluid further includes a viscosifying agent that is not a plant-based polysaccharide gum. The method further includes providing the oilfield treatment fluid to a high pressure pump, and operating the high pressure pump to treat a formation fluidly coupled to a wellbore. |

1. An oilfield treatment fluid, comprising:
an aqueous HCl solution comprising between greater than 15% and 45.7% HCl by weight, inclusive; an HCl fixing agent (FA) comprising at least one of urea and a urea derivative, wherein the FA is present in an amount comprising a molar ratio of FA:HCl between 0.5 and 2.5 inclusive; and a viscosifying agent present in an effective amount, wherein the viscosifying agent is not a plant-based polysaccharide gum. |
