SECURING A WELL CASING TO A WELLBORE

摘要

A well casing for receiving well fluid from a producing formation includes a first tubular section (30) that has a tortuous outer surface for directing the flow of a bonding agent around the exterior of the first tubular section (30). The first tubular section (30) has a central passageway. The well casing also has a second tubular section (21) that is coaxial with and is connected to the first tubular section (30). The second tubular section (21) has at least one opening for directing well fluid into a central passageway of the second tubular section.
