Temperature-resistant high-thermal-conductivity admixture for well cementation cement and preparation method of temperature-resistant high-thermal-conductivity admixture
The invention relates to the technical field of oil and gas field resource development well cementation materials, in particular to a temperature-resistant high-thermal-conductivity admixture for well cementation cement and a preparation method thereof.The temperature-resistant high-thermal-conductivity admixture for well cementation cement is prepared from, by weight, 40%-60% of a heat conduction reinforcing material, 30%-45% of a reinforcing material and 10%-15% of polyetherimide, the heat conduction reinforcing material is a mixture formed by mixing molybdenum disilicide, tungsten diboride, zirconium diboride and titanium diboride according to the mass ratio of (5-7): (1-2): (1-2): 1 and then modifying the mixture. The temperature-resistant high-thermal-conductivity admixture for well cementation cement has the characteristics of strong high-temperature resistance, high thermal conductivity coefficient, good toughness and the like, has good compatibility with cement, does not influence the working performance of a well cementation cement slurry system, can participate in a cement hydration reaction, and improves the high-temperature resistance of well cementation cement slurry.
