DEVICE PROTIVOPOLETNOE for face MECHANISMS

摘要

DEVICE NROTIVOPOLETNOE; For face MECHANISMS; Noleznaya The invention relates to mining and can be nromyshlennosti isnolzovana to prevent falling and leaving in the well downhole mechanisms, mainly submersible centrifugal pump installations for oil, and their breakage.; The device consists of fixing elements, preferably bolts, the fastening flange connections downhole mechanisms, each of which contains therein nrodolnom existing bore needle with thickenings at both its ends in the form of heads. The length of the spoke greater than the length krenezhnogo element to allow formation of a gap in a place submerged installation dissection.; In the case of destruction of the fastening elements in any flanged connection setup occurs submersible its subdivision, and separating the lower part hangs on the needles, and the formation fluid is pumped through the formed gap results in well annulus that immediately fixed flow sensors. The well is de-energized and repaired.; The use of the proposed device will prevent the fall of the submersible installation or part nr dismemberment in any of its flanged connection, thereby improving conditions for well workover, reducing its consumption of materials and cost. 5 FIG.; ABSTRACT OF THE APPLICATION; For utility model number; In MKI5E21 40/00
