摘要 |
<p>The present invention relates to a device which can be used in an offshore or onshore oil and/or gas well for the purpose of increasing the production of the well. The device comprises an outer structure in which a first and a second pressure-actuated bellows device are arranged, the first and second pressure-actuated bellows device, via a support means, being in fluid communication with each other. The support means is fixedly mounted internally in the outer structure, the support means thereby delimiting an open and a closed space for respectively the first and the second pressure-actuated bellows device, wherein the closed space is filled with a fluid under pressure, whilst the open space is in fluid communication with a surrounding fluid.</p> |
