Heat conduction cement slurry system
The invention discloses a heat conduction cement slurry system which comprises water and dry powder. The mass ratio of water to dry powder is (0.43-0.45): 1; the dry powder comprises the following components in percentage by mass: 83%-87.8% of high-temperature-resistant cement, 10% of a heat conduction agent, 2%-5% of a density regulator, 0.1%-1% of a coagulant and 0.1%-1% of a fluid loss agent; the high-temperature-resistant cement is pure calcium aluminate cement; the heat conduction agent comprises, by mass, 35% of single crystal aluminum nitride, 25% of aluminum alloy 1050 powder, 20% of aluminum oxide powder, 10% of green silicon carbide and 10% of copper powder. The density regulator is high-temperature-resistant hollow glass floating beads; the coagulation accelerator is prepared from CaCl2 and Na2S04 according to the mass percent of 1: 1; and the fluid loss agent is polyacrylamide. The heat conduction cement slurry system solves the problems that the heat conduction coefficient of existing well cementation cement stone is small, and heat energy in a casing pipe is stably transmitted to a reservoir stratum.
