Abstract
The invention relates to a compound resin high-temperature-resistant anti-collapse water-loss reducing agent for a drilling fluid, belonging to drilling fluid assistants. The water-loss reducing agent is prepared from the following components in percentage by weight: 5-15% of phenol, 20-30% of formaldehyde, 5-10% of anhydrous sodium sulfite, 3-8% of nano pyrosulfite, 10-18% of sodium hydroxide, 30-55% of humic acid and the balance of water. The water-loss reducing agent can ensure the stable dispersed state of clay, prevent the dispersed clay from aggregation and growth and ensure sufficient clay particles in the drilling fluid, thereby being beneficial to forming a compact sludge cake; due to the deformability of the resin, the formed sludge cake is thin and compact, and has the advantages of favorable compressibility and lower water loss; the water-loss reducing agent can enhance the lubricating property of the sludge cake, and has certain salt resistance; and the protecting wall performs the anti-collapse function on the compact sludge cake at high temperature.
