Treatment Measures on Scale Formation of ASP Flooding
Using X-ray diffraction to analyze the scaling samples to discuss the scaling causes. The results show that the main ingredients of scaling are CaCO3, CaSiO3 and non-crystal SiO2 in ASP flooding. Taking "heating concentration state", "scaling ions change" and "inhibition rate" as the evaluation indexes, evaluate the British net yuan scale removal instrument, Germany scale-buster and Korea magnetic antiscale apparatus which are all advanced foreign physical instruments online, and search for the suited antiscaling instruments for oilfield. Results show that the antiscaling effect of British net yuan scale removal instrument on the ASP flooding is better, the inhibition rate reach 69.3 %.
