Abstract

Klare fluider red nøy densitet for anven-delse son fullførings-, pakkings- og perforeringsnedia i olje- og gassbrønn-fomaa joner ned høye car bo nat- og/eller bøye solfationekonsentrasjoner er dannet fra vandige oppløsninger av sinkbroaid og ett eller flere alkaliawtallbromider og. nar densiteter som ligger innen omra-det fra 1,38 til 2,46 kg/l og en pH son ligger innen området fra 1,0 til 7,5.Clear fluids with sufficient density for use as completion, packing and perforating agents in oil and gas well formations down high carb night and / or bending solfation concentrations are formed from aqueous solutions of zinc broaid and one or more alkali metal bromides and. when densities are in the range of 1.38 to 2.46 kg / l and a pH zone is in the range of 1.0 to 7.5.
