Operations in liquidation of wall sticking and casing pipe that occur in drilling arethe most difficult and time-consuming. One of the ways to improve the requirements ofcasingstring cementing is the use of different chemical additives in cement that change the structureof well cement. One of them is hydrophobic additive «Silpan-Р», which effectiveness isdescribed in the article. Own view on the issue of process occurrence of differential wallsticking that is different from the existing ones was offered.Keywords: drill string, differential sticking, osmosis, hydrophobic additive «Silpan-Р»,well, pressure. popup.nrat_date 2026-04-19 Close
