Drilling fluid conditioner and drilling fluid using the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a drilling fluid conditioner using a PVA resin that can contribute to suppression of hydrated swelling of bentonite even in the presence of salts, and a drilling fluid using the same. A drilling fluid adjusting agent containing a PVA-based resin containing a 1,2 diol structural unit in a side chain. [Effect] It has excellent solubility in the presence of salts such as potassium ions, and is excellent in inhibiting hydration and swelling of bentonite. [Selection figure] None |
