Thickening time control agent for solving abnormal gelling and thickening time upside-down of high-temperature cement paste and preparation method of thickening time control agent
The invention provides a thickening time control agent for solving the problems of abnormal gelling and upside-down thickening time of high-temperature cement paste and a preparation method of the thickening time control agent. The thickening time control agent comprises the following raw materials in parts by weight: 1-4 parts of aluminum salt, 1-2 parts of sodium salt, 1-2 parts of calcium salt, 1-2 parts of magnesium salt and 1-6 parts of other materials, wherein the other materials comprise one or a combination of more of zinc oxide, olivine, spodumene and kyanite. The preparation method of the thickening time control agent comprises the step of uniformly mixing the aluminum salt, the sodium salt, the calcium salt, the magnesium salt and other materials in parts by weight to obtain the thickening time control agent. The thickening time control agent provided by the invention can solve the problems of swelling of a thickening curve, poor linear relation between thickening time and dosage, upside-down hanging of a temperature interval and the like caused by core wrapping of cement paste at high temperature, and meanwhile, the thickening time control agent has no adverse effect on rheological property, stability, water loss performance and the like of the cement paste, and can improve the well cementation quality.
本发明提供了一种解决高温水泥浆异常胶凝和稠化时间倒挂的调凝剂及其制备方法。以重量份计，该调凝剂的原料组成包括：1～4份的铝盐，1～2份的钠盐，1～2份的钙盐，1～2份的镁盐以及1～6份的其他材料；其中，所述其他材料包括氧化锌、橄榄石、锂辉石和兰晶石中的一种或几种的组合。该调凝剂的制备方法为：按照重量份，将铝盐、钠盐、钙盐、镁盐和其他材料混合均匀，得到调凝剂。本发明的调凝剂可解决高温下水泥浆“包心”引起的稠化曲线“鼓包”、稠化时间与加量线性关系差及温度区间“倒挂”等问题，同时，该调凝剂对水泥浆的流变性、稳定性及失水性能等无不良影响，可提高固井质量。
