Abstract

Sammensetning som omfatter en blanding av et saltvann og en flytende olje og (Å) en viskosltetseakende mengde av minst en ester av en karboksyinneholdende inter- polymer eller salt derav der interpolyraeren blir fremstilt ved polymeriserlng av en olefln valgt fra gruppen som består av alfa-olefiner og vlnylaromatlske monomerer med minst et alfa, beta-uraettet karboksyl- acylerlngsralddel, og forutsatt at når olefinet er vinyltoluen, da er det alfa, beta-umettede karboksyl- acyleringsmldlet et alfa, beta-umettet dlkarboksyl- acyleringsmlddel. Sammensetningene er nyttige som borefluidet, så vel som ferdlgstilllngsfluider. Esterne av den karboksyinneholdende interpolyraeren eller saltene derav, skaffer til veie fordelaktig viskositet, formasjonsstabiliserlng, emulgering og reologlegen- skaper til fluidene.A composition comprising a mixture of a saline and a liquid oil and (Å) a viscosity-lowering amount of at least one ester of a carboxy-containing interpolymer or salt thereof, wherein the interpolymer is prepared by polymerization of an olefin selected from the group consisting of alpha olefins and vinyl aromatic monomers having at least one alpha, beta-unsaturated carboxyl acylation agent, and provided that when the olefin is vinyltoluene, the alpha, beta-unsaturated carboxyl acylating agent is an alpha, beta-unsaturated dicarboxyl acylating agent. The compositions are useful as the drilling fluid as well as the finishing fluid. The esters of the carboxy-containing interpolar or its salts provide beneficial viscosity, formation stabilization, emulsification and rheology properties of the fluids.
