摘要
The present invention refers to a flow additive useful to improve the extraction and displacement of light or heavy crude oils, which comprises an aqueous emulsion containing hollow or solid synthetic microspheres, a component able to alter the superficial tension, high molecular weight polyelectrolytes, a glycol-type antifreeze and fluidity improvement agent and a thickening agent. The additive according to the present invention improves the flow of crude oil pumped from the wells to storage tanks and also cleans and prevents against incrustations of paraffin and heavy hydrocarbons derived from the perforation of the petroleum wells drilling, even though in low temperatures (below of 0 Celsius degrees).
