Enzymatic and Oxidizing Agents for the Decomposition of Polymers Used in the Composition of Drilling Muds

The article presents the results of research on influence enzymatic and oxidizing agents polymers used in drilling mud technology. calcium hypochlorite, urea peroxide, sodium persulfate, amylase cellulase. This allowed us to determine optimal concentrations these order reduce rheological parameters muds. ability enzymes oxidants decompose colloids composition muds was determined basis measurements their properties filter cakes. final effect presented development a treatment method before cementing procedure washer fluids containing or be prepare borehole for procedure. selected contained starch cellulose polymer colloids, which selection appropriate depending type set mud. Positive were obtained regarding possibility thinning immediately cementing, as well using fluids.
