SEALED DOWNHOLE EQUIPMENT AND METHOD FOR FABRICATING THE EQUIPMENT
摘要
A method and apparatus for preventing fluid flow and contamination to a cement body includes a resin cap covering an exposed end of the cement body. The cement body may attach an inner sleeve to an outer sleeve. The fluid flowing through the outer sleeve is prevented from contacting the exposed surface by the resin cap. Resin caps at both ends of the cement body along with resin layers along the side may be included. The resin prevents contamination and creation of micro-annuli in the cement body.
