Carbon nanotube reinforced temperature-resistant gel plugging and adjusting agent as well as preparation method and application thereof

The invention discloses a temperature-resistant gel plugging agent which comprises the following components in percentage by weight: 0.15%-0.3% of an acrylamide/vinyl pyrrolidone/styrene copolymer, 0.1%-0.2% of a cross-linking agent, 0.2%-0.4% of a stabilizer and the balance of water. The preparation method of the temperature-resistant gel plugging and regulating agent comprises the following steps: dissolving an acrylamide/vinyl pyrrolidone/styrene copolymer in water to obtain a first solution; dissolving a cross-linking agent and a stabilizer in water to obtain a second solution; mixing the first solution and the second solution to obtain a gelatinizing solution; and aging the gelatinizing solution. The temperature-resistant gel plugging and adjusting agent can resist high temperature of 250-280 DEG C, has a good plugging and adjusting effect, and can be used for deep plugging and adjusting of thermal production wells. 本发明公开了一种耐温冻胶堵调剂，以重量百分比计，包括：丙烯酰胺/乙烯基吡咯烷酮/苯乙烯共聚物0.15％～0.3％，交联剂0.1％～0.2％，稳定剂0.2％～0.4％，和余量水。本
