AGGREGATING REAGENTS AND METHODS FOR MAKING AND USING SAME

摘要

Methods including using fluid including an aggregating composition including heterocyclic aromatic amines, substituted heterocyclic aromatic amines, polyvinyl heterocyclic aromatic amines, co-polymers of vinyl heterocyclic aromatic amine and non amine polymerizable monomers (ethylenically unsaturated mononers and diene monomers), or mixtures or combinations thereof in the absence of phosphate esters or amine-phosphate reaction products during drilling or fracturing operations to alter self-aggregating properties and/or aggregation propensities of the particles, surfaces, and/or materials in or entrained in the fluid.

1. A method for drilling comprising the step of:
while drilling, circulating a drilling fluid, to provide bit lubrication, heat removal and cutting removal, where the drilling fluid includes an aggregating composition comprising heterocyclic aromatic amines, substituted heterocyclic aromatic amines, polyvinyl heterocyclic aromatic amines, co-polymers of vinyl heterocyclic aromatic amine and non amine polymerizable monomers, or mixtures and combinations thereof in the absence of phosphate esters and amine-phosphate ester reaction products, and where the aggregating composition alters an aggregation potential or propensity and/or a zeta potential of particulate materials in the drilling fluid or that becomes entrained in the drilling fluid to increase solids removal.
