High-thermal-conductivity well cementation admixture, application thereof and well cementation cement slurry
The invention relates to the technical field of well cementation, in particular to a well cementation admixture with high thermal conductivity, application of the well cementation admixture and well cementation cement paste. The well cementation admixture is prepared from the following components in parts by weight: 100 parts of a component with a large particle size, 40 to 120 parts of a component with a small particle size, 0.05 to 0.85 part of a nano component and 0.01 to 3.5 parts of a surfactant, wherein the particle size of the coarse particle size component is 100-1000 [mu] m, the particle size of the fine particle size component is 1-80 [mu] m, and the particle size of the nanometer component is 1-50 nm. According to the invention, specific components are selected, the particle sizes of the coarse-particle-size component, the fine-particle-size component and the nanometer component are regulated and controlled, and a small amount of surfactant is added, so that the compatibility of the well cementation admixture with high thermal conductivity and cement can be remarkably improved; the cement stone formed after the well cementation cement slurry containing the heat-conducting well cementation admixture is hydrated has good heat conductivity and compression resistance.
本发明涉及固井技术领域，具体地涉及一种高导热固井掺料及其应用和固井水泥浆。所述固井掺料包括：100重量份的粗粒径组分、40‑120重量份的细粒径组分、0.05‑0.85重量份的纳米组分、0.01‑3.5重量份的表面活性剂；其中，所述粗粒径组分的粒径为100‑1000μm，所述细粒径组分的粒径为1‑80μm，所述纳米组分的粒径为1‑50nm。在本发明中，通过选择特定的组分并且调控粗粒径组分、细粒径组分和纳米组分的粒径，添加少量的表面活性剂，可以显著改善高导热固井掺料与水泥的相容性，使得含有导热固井掺料的固井水泥浆在水化后形成的水泥石可以兼顾良好的导热性和抗压性能。
