| 成果简介 | NOVELTY - Pressure compensator of the downhole geophysical instrument includes a casing filled with liquid. Casing is rigidly connected in series with coupling and bellows filled with liquid of different density. Coupling on the side of the casing is equipped with an internal annular projection, and on the side of the bellows – with a nut. Piston with a plug is installed in the inner cavity of the coupling, which separates liquids from the casing and bellows. Piston is made with possibility of sliding along the inner cavity of the coupling. Bellows is plugged with a plug. USE - Borehole geophysical instruments. ADVANTAGE - Disclosed design is reliable, preventing mixing of fluid inside the casing with well fluid, and also simplifies maintenance, increases overhaul life of the device. 1 cl, 1 dwg |
