Zusammenfassung:MIXTURES OF FIBERS AND SOLID PARTICLES ARE EFFECTIVE FOR CURING FLUID LOSSES AND LOST CIRCULATION IN A SUBTERRANEAN WELL. STIFF FIBERS ARE MORE EFFECTIVE THAN FLEXIBLE ONES; HOWEVER, MIXTURES OF STIFF AND FLEXIBLE FIBERS HAVE A SYNERGISTIC EFFECT. THE QUANTITY AND PARTICLE-SIZE DISTRIBUTION OF THE SOLIDS ARE OPTIMIZED ACCORDING TO THE STIFFNESS, DIMENSIONS AND CONCENTRATIONS OF FIBERS. (FIG. 24)
