چکیده انگلیسی
The induction time, tind, of calcium carbonate precipitation in porous rocks was experimentally measured under dynamic conditions at temperatures from 25 to 120â°C with the use of a radiotracer technique, where the gamma-emitting nuclide 47Ca was used as a tracer in order to monitor the scale deposition at real time. Based upon nucleation theory and experimental observations, the following improved correlation is proposed: logtind(min)=3.2â3.0SIâ959.8T+1849.9SIT. This equation predicts satisfactorily the induction time of calcium carbonate scale formation under specific dynamic (flow) conditions in the near-well region (T is the absolute temperature in K, and SI is the saturation index, SI=logSR, where SR is the saturation ratio).
