FIELD: oil production, particularly methods or apparatus for cleaning boreholes or wells. ^ SUBSTANCE: method involves determining concentration of salt-generation ions in formation water; calculating daily salt amount to be scaled on pipeline walls after mixing product of all wells; determining time of full pipeline blockage with salt from the following relation: T=pi.D2.L.rhosalt/4.Ql.Csalt.K1 , where T is time of full pipeline blockage with salt, days, D - inner pipeline diameter, m, L is pipeline length covered with salt deposits, rhosalt is salt density, g/l, Ql is summary water output from wells, m3/day, Csalt is total amount of salt-generation ions, g/l, K1 is coefficient, which takes into consideration salt part to be scaled on pipeline wall. ^ EFFECT: increased prediction reliability of salt deposit prediction at early stage. ^ 1 ex, 1 tbl |
