| 摘 要： | 为了了解地热系统中结垢情况及优选绿色高效阻垢剂，选定河北博野某结垢地热井，针对现场地热供暖系统情况，分析了结垢类型，研发设计了阻垢剂加注装置，现场开展了多种工况条件下阻垢剂的加注试验，计算评价了阻垢率。结果表明：该地热井结垢成分为文石和方解石；所选择的四种阻垢剂其阻垢率均在80%以上，效果最好的一种阻垢剂在加注浓度35.95 mg/L时，阻垢率达到94.49%。一个采暖季的阻垢效果表明，在井下加注化学阻垢剂可有效解决井筒和地表设备的碳酸钙结垢。

| Abstract: | Fouling in geothermal systems reduces the efficient exploitation of geothermal fluids. In this paper, a scaled geothermal well in Bono, Hebei is selected. The type of scaling is analyzed while the scale inhibitor filling device is developed and designed and the scale inhibitor filling test is carried out in the field under various working conditions, with which the scale inhibition rate is calculated and evaluated. The results showed that the scale components of the geothermal well were aragonite and calcite, and that the scale inhibition rates of the four selected scale inhibitors were all above 80%, among which the best one scale inhibitor reached 94.49% at a spiking concentration of 35.95 mg/L. The scale inhibition effect in one heating season shows that the chemical scale inhibitor can effectively solve the calcium carbonate scaling in wellbore and surface equipment. |
