High-strength microbead lightening material for oil well cement and preparation method of high-strength microbead lightening material
The invention discloses a high-strength microbead lightening material for oil well cement and a preparation method thereof.Raw materials needed by the preparation technology comprise glass powder, aluminum oxide composite powder, calcium carbonate powder, a boron compound and an organic binding agent, and the high-strength microbead lightening material suitable for the oil well cement is prepared through a high-temperature foaming and tempered glass structure coupling method. The high-strength microbead lightening material for the oil well cement overcomes the defects that traditional expanded perlite serving as an oil well cement lightening material is low in strength, not suitable for mechanical construction and the like, has the advantages of being high in strength, low in water absorption rate, low in stacking density and the like, is simple in preparation process and can achieve large-scale production of enterprises.
本发明公开了一种用于油井水泥的高强微珠减轻材料及其制备方法，该制备技术所需原料包括玻璃粉、氧化铝复合粉、碳酸钙粉、硼化合物和有机结合剂，通过高温发泡和强化玻璃结构耦合方法，制备出适用于油井水泥的高强微珠减轻材料，克服了传统膨胀珍珠岩作为油井水泥减轻材料低强度和不宜机械化施工等缺点，本发明制备的油井水泥用高强微珠减轻材料具有高强度、低吸水率和低堆积密度等特点，并且制备工艺简单，可实现企业规模化生产。
