| 中文摘要:稠化特性是地热固井作业中水泥浆的一个重要性能。在模拟不同温度和压力条件下，对水泥浆进行了稠化试验。并对７种缓凝剂进行了高温缓凝试验评价，认为硼酸是一种有效的高温水泥缓凝剂。并用它对两种地热水泥浆的稠化特性进行了调节。 |

| Abstract:Thickening characteristics is an important behaviour of cement slurry in the operation of geothermal well cementation. The thickening tests have been carried out under the simulated conditions of temperature and pressure. The appraisal has been made of seven kinds of retarders through high temperature retarding tests, the results show that Boric acid is an effective retarder for high temperature cement slurry, which is employed in regulating the consistency of two high temperature geothermal cement slurries. |
