Inventia face parte din domeniul "Aditivi si fluide de foraj" si îsi propune sa introduca în practica de santier un nou aditiv care sa permita consumarea hidrogenului sulfurat din fluidele de foraj, fluidele de perforare, fluidele de packer s.a. Aditivul este un amestec de produse secundare anorganice pe baza de zinc cu un chelat de zinc sau fier al acidului lignosulfonic, un oxid de fier spongios si cu sarea de sodiu a acizilor humici. Aditivul îsi gaseste aplicarea în toate procesele de foraj si extractie, acolo unde se semnaleaza contaminarea fluidelor din sonda cu hidrogen sulfurat.The invention is part of the field of "Additives and Drilling Fluids" and aims to introduce into the site practice a new additive to allow the consumption of hydrogen sulfide from drilling fluids, perforating fluids, packer fluids, etc. The additive is a mixture of zinc-based inorganic by-products with a zinc or iron chelate of lignosulfonic acid, a sponge iron oxide, and sodium hypochlorite of humic acids. The additive finds application in all drilling and extraction processes, where contamination of fluid in the hydrogen sulfide probe is reported.
