ABSTRACT
This paper puts forward a new method to screen scale inhibitors. It's an improvement to the traditional method of solid suspended objects measurement named Filter Membrane Filtration Method. The material which is extracted via filter membrane<0. 45 µm is defined as suspended scale, and the material which attaches to the surface of conical flask is defined as sedimentation scale. The content of the sum of suspended scale and sedimentation scale is called total scale quantity. We create a new method to evaluate and select scale inhibitors via measuring the change of scale in quality, observing the change of scale in morphology by polarizing microscope and scanning electron microscope, and analyzing component of scale by X-ray diffraction and energy spectrum analysis. Compared with industrial standard, this new method can estimate scale inhibitors performance so handy, quickly, effectively and reliably that we think it have the value of popularization in the oilfield.
