Document Type and Number:
WIPO Patent Application WO2002002905
Kind Code:
B1
Abstract:
The invention relates to the oil industry and can be used for increasing well productivity by increasing the oil flowrate, for a well workover and isolation of a water-encroached bench. The inventive packer (1) comprises a body (4) provided with a sealing ring (5) which is collapsible in a radial direction and fitted with a drive. Said drive is embodied in the form of a chamber (6) containing a working medium in an such initial aggregative state in which it occupies a minimum volume, and comprises an element transferring the working medium from the initial state to another state. In order to fix the packer (1) in the well, the working medium of the drive of the sealing ring is transferred from the initial aggregative state to another state, where the working medium occupies a greater volume.
