Well bore device and method for sand control

摘要: A process and apparatus for removing particulate matter from fluid wells where low pH conditions or high temperature exist. The comprises forming a cylindrical shaped retainer having one closed open end. Said has an inner outer wall which join with said end to provide space between walls. An ended fused porous refractory tube is fitted within space. retainer, the therein, affixed delivery tube. This directed into formation used control fines sandflow entrained in fluids obtained formation. Being sandwiched walls, protected shock easily removed cleaning. chemically resistant endures temperatures encountered during steam-flooding steam injection.
