Surface Properties of High-Performance Microbeads and Their Effects on the Performance of Cement Slurry

摘要: 采用扫描电镜(SEM)、元素分析(XPS)、硅钼黄法、姜黄试纸法、滴定等方法,分析研究了固井水泥浆中所用高性能空心玻璃微珠(简称空心微珠,HGM)的表面性质,并评价了空心微珠对水泥浆性能的影响。结果表明,空心微珠外表呈大小不等球体,少量球体表面存在孔洞缺陷,除玻璃的主要组成外,表面含有少量有机偶联剂;表面存在硅酸钠、硼酸钠等少量可溶性附着物,附着物含量随批次不同有所不同,其中附着物含量过大会对固井水泥浆的性能产生不良影响,其中的可溶性硼含量是影响水泥浆性能的主要因素,固井使用时应对其进行控制。根据目前实验,认为硼砂含量低于0.38%对水泥浆的影响不大,因此尽量选用硼砂含量此范围内的微珠使用。Abstract: Surface properties of high-performance hollow glass microbeads (HGM) used in cement slurry were studied using SEM, XPS, silicon molybdenum yellow spectrophotometry, turmeric paper and titration methods, and the effects of HGM on the properties of cement slurry evaluated. It was found that the particles of HGM are in spherical shapes of different sizes. Some of the spheres have cavities on their surfaces. The composition of HGM, apart from glass, includes small amount of organic coupling agents on the surfaces of HGM. Also on the surfaces of HMG are soluble adhesive substances such as sodium silicate and sodium borate. The amount of the adhesive substances is different in different batches of HGM. Too many adhesive substances on the surfaces of HGM have bad effects on the properties of cement slurry. In the adhesive substances, the soluble boron content is the main factor affecting the properties of cement slurry, and should be controlled when selecting HGM for well cementing. According to laboratory experiment, borax does not affect signifcantly the properties of cement slurry if the content of borax is less than 0.38%, thus, HGM with borax content in this range is preferred in terms of oil well cementing.
