METHOD AND APPARATUS FOR CEMENTING PRODUCTION TUBING IN A MULTILATERAL BOREHOLE |
摘要 |
A hydraulically actuated anchor and a mechanically actuated packer are used in combination to secure a production tubing system in a lateral prior to injection of a cement to line the lateral borehole in which the production tubing is positioned. The packer is expanded to prevent fluid cement material from flowing past the packer into a junction area of the lateral with other laterals and aid the removal of superfluous cement material after hardening of the injected cement material around the production tubing syste m. |
