Abstract

PURPOSE: A muddy water preparation agent for excavation using ventonite stabilized dispersion that is composed of a modified polyvinyl alcohol having hydrophobic groups and anionic hydrophilic groups introduced on the side chains of the polymer, thus showing high caving and overflowing prevention and having suitable viscosity and colloid stability.
CONSTITUTION: A modified polyvinyl alcohol is obtained by introducing hydrophobic groups on the side chains through saponification of a copolymer from a vinyl compound with hydrophobic groups, preferably alkyl vinyl ether or α-olefin, and vinyl acetate or through acetalization of polyvinyl alcohol with an aliphatic aldehyde, at the same time, introducing anionic hydrophilic groups on the side chains through saponification of a copolymer from a vinyl compound bearing anionic hydrophilic groups, preferably an ethylenically unsaturated aliphatic dicarboxylic acid, and vinyl acetate or through reaction of polyvinyl alcohol with sulfuric acid or chlorosulfonic acid. The resultant polymer is used as the muddy water preparation agent.
USE: The foundation work of construction or boring of petroleum wells.
