ABSTRACT:
A bridge plug for use in plugging a well at a subterranean location and adapted to be set in place by insertion through a tubing string. The bridge plug comprises an elongated vent tube supporting upper and lower petal basket structures, each of which comprises a plurality of petal leaves movable between a retracted position and an expanded position. In the expanded positions the petal leaves for the upper and lower baskets form conical configurations which face upwardly and downwardly respectively. Upper and lower fabric bags cover the respective petal basket structures respectively and extend over the inner and outer surfaces of the petal leaves. Each of the petal basket structures are further provided with conically shaped liners formed of an impermeable material inside the bags and interposed between the inner surfaces of the petal leaves and the conforming portions of the bags. The liners may be formed of an adhesion-resistant material such as fiber-glass fabric coated with a polytetrafluoroethylene.
