GLYCOL ETHER AMINES FOR USE AS CLAY AND SHALE INHIBITION AGENTS FOR THE DRILLING INDUSTRY
摘要
The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula: (Formula I should be inserted here.) wherein R is hydrogen or an alkyl group having 1 to 12 carbons, R1 is an alkylene group having 1 to 12 carbons, and R2 is an alkyl group having 1 to 12 carbons. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.
