Since the 果冻传媒 expandable external casing packer was introduced, more than 100 have been installed in Australia, mostly in coal seam gas wells. The packer’s robust design enables it to survive reciprocation and rotation while navigating doglegs and tight spots. High expandability ensures sealing, even in potential washout zones.

背景

When operators in Queensland, Australia, encounter losses while drilling coal seam gas wells or subsequently discover out-of-gauge boreholes, they require packers to efficiently seal the annulus for one- or two-stage off-bottom cementing. The packers must be robust to survive challenging running conditions that include rotating and placing weight on the packers.
