Abstract
A sand control screen for heavy oil thermal recovery, including: a core base pipe having a plurality of base-pipe holes distributed on a pipe body thereof; a filtering sleeve sleeved on the core base pipe and arranged with respect to the base pipe holes; and a non-welded support disk mounted on the core base pipe and fastening the filter sleeve to the core base pipe by means of a wedge insertion locking and sealing structure. The invention solves the problems in the prior art in which sand control screen has a poor reliability in a high-temperature condition of a thermal production well, resulting in potential safety risks of down hole sand control operation of the screens. In addition, the sand control screen of the present invention has a long service life, thus improving cost effectiveness of oil wells.
