High-thermal-conductivity well cementing material as well as preparation method and application thereof
The invention discloses a high-thermal-conductivity well cementing material as well as a preparation method and application thereof. The high-thermal-conductivity well cementing material comprises the following components in parts by weight: 100 parts of cement, 15-30 parts of silicon powder, 0.4-0.6 part of a water reducing agent, 0.2-0.3 part of an early strength agent and 70-80 parts of water. The heat conductivity coefficient of the high-heat-conductivity well cementing material provided by the invention can reach more than four times that of conventional cement paste, the heat conductivity coefficient of the well wall of a geothermal well can be remarkably improved, and full utilization of geothermal energy is realized.
本发明公开了一种高导热固井材料及其制备方法与应用，所述高导热固井材料包括水泥、硅粉、减水剂、早强剂和水，其中，所述水泥100份、硅粉15‑30份、减水剂0.4‑0.6份、早强剂0.2‑0.3份和水70‑80份。本发明所提供的高导热固井材料的导热系数能达到常规水泥浆的四倍以上，其可显著的提高的地热井井壁的导热系数，并实现地热的充分利用。
