Zusammenfassung:	oil production industry, construction of inclined wells of various assignment with horizontal termination of shaft. SUBSTANCE: jet mixer is set in lower part of casing string. Buffer fluid is pumped into casing string. One or several portions of grouting mortar are pumped. One or several portions of forcing fluid are pumped. Grouting mortar is mixed in jet mixer for its homogenization. Buffer fluid and part of grouting mortar are driven into hole clearance under turbulent condition. The rest of grouting mortar is forced under structural mode. EFFECT: formation of grouting mortar homogeneous in density in cemented interval. 1 dwg, 1 tbl
