Heat-resistant agent used for control sand of steam huff and puff heavy oil well

摘要：

　　Heat-resistant agent containing hydroxymethyl group was synthesized from coal tar,which has similar structure with phenolic resin and could improve the heat resistance of phenolic resin sand control agent.The results showed that the heat resistance of the sand control agent was improved by adding 10%to 30%heat-resistant agent,after 280℃high temperature treatment for 7d,the compressive strength of consolidated core was increased to more than 5MPa.The compressive strength of consolidation core was not decreased after immersion in formation water,crude oil,acid or alkaline medium,which showed good resistance to medium immersion.The sand control agent had small core damage and the core permeability damage ratio of sand control agent consolidation was only 18.7%.
