Proračun cementiranja kolona u uvijetima gubljenja kapljevina u probušenim propusnim naslagama stijena

The problem of cementing the string of casing in areaswhere the drilling or cementing fluids are lost in porous, fractured, and cavernous rocks, deserves special technical treatment. Obtaining the required volume of cement mixture in the annular space behind the casting, under above mentioned conditions, most frequently depends on pressures occuring during cementing operations in critical intervals of the borehole. Successful cementing of casing in such circumstances should necessarily be preceded by special technical procedures.
