| titleOfInvention | Clay-free drilling fluid |
| abstract | FIELD: chemistry. n SUBSTANCE: invention concerns oil and gas industry, particularly clay-free drilling fluids (CFDF) used in drilling wells, including sloping and horizontal holes and side shafts at low formation pressure. Clay-free drilling fluid includes, wt %: Saraksan-T 0.3-0.8, Polycell KMK-BUR2 1.1-2.1, OP-10 0.5-1.2, water-repelling fluid GKZh-11N 1.0-2.9, the rest is water. n EFFECT: enhanced efficiency of well drilling at low formation pressure due to application of low-density CFDF with improved structural properties and rheological parametres ensuring enhanced containment and transportation properties while preserving filtration properties and improving environmental safety of storage. n 1 tbl, 6 ex |
