Experimental research of stability (destruction) of real oil-water mix
tures under the influence of chemical agents - demulsifiers - was cond
ucted for Mamontovskoye and Teplovskoye oil fields. Temperature condit
ions of supply network of preliminary water drainage installation in T
eplovskoye field were reviewed, and four peculiarities of such network
were detected. Structure and hydraulic conditions of oil-water mixtur
e dynamics in supply network of preliminary water drainage unit were i
nvestigated in Teplovskoye field, and conclusions were made.
