Study on the Mechanism of Enhancing Cementing Quality with the Downhole Shear Swirling Flow Vibration Cementing Tool
View through CrossRef
Abstract
Downhole shear swirling flow vibration cementing tool has shear, rotational flow and vibration triple effects. It can improve cementing quality in various aspects. This paper developed discussion in the aspects of the tool to change cementing fluid performance by shear, to realize turbulent displacement and improve the wall shear stress by swirling flow, to change periodically relative position of clearance by casing eccentric revolution, to increase compression strength of cement by vibration and so on. It analyzed the mechanism of enhancing cementing quality of the downhole shear swirling flow vibration cementing tool in detail. It deepened the understanding of the tool. Then the research results help to promote the tool further application in oil and gas well cementing engineering field, and further increase the oil and gas well cementing quality.
