摘要	Calcium carbonate precipitation is a common problem in geothermal industry, which dramatically hampers geothermal development and also increases maintenance costs. To solve such a problem, here the whole process of scaling and antiscaling, including scaling type analysis, scaling process simulation, flashing point determination, antiscaling equipment design, inhibitor selection, antiscaling experiment and inhibition efficiency evaluation is investigated. The results show that the flashing point can be calculated by a mathematical model using wellhead and well bottom parameters. Chemical inhibitors injected into brine below the flashing point can effectively solve the problem of calcium carbonate precipitation, obtaining an inhibition efficiency of 89.37% with an inhibitor concentration of 25.61 ppm.
