Abstract
The utility model relates to a frame-typed test sealing ring, belonging to a sealing device arranged in a test sealing section in a bedding water-injection test of oil field exploitation. The utility model comprises a rubber ring (2) and an O-shaped steel ring (1) which is arranged in the inner part of the rubber ring (2), and the O-shaped steel ring (1) is closely connected with the rubber ring (2). The utility model not only can seal a central channel of an eccentric water-distributor and an annular space of a sealing section, but also can wear well with high strength. The utility model has the advantages that the sealing device has excellent sealing effect and is wear-resistant and durable, and the distortion is rare.
Description
Technical field: the utility model belongs in the oil field development layered water injection test, is installed in a kind of seal arrangement on the testing seal section.
Background technique: the seal ring during separated-zone water infection oil field well surveying examination at present on the used testing seal section, it makees " O " shape seal ring with oil resistant rubber.This seal ring is when test, because insufficient strength, so be easy to be worn or scratch, and cause sealing effect bad, directly influence the test passes rate.
Summary of the invention: the purpose of this utility model be the development a kind of skeleton test seal ring, it have wear-resistant, intensity is high, the characteristics of good sealing effect.The utility model includes rubber ring 2, and it also includes O shape steel ring 1.O shape steel ring 1 is arranged on the inside of rubber ring 2, and O shape steel ring 1 closely is connected with rubber ring 2.This is practical when can be implemented in test not only can packing live eccentric injection mandrel central duct and seal section annular space, but also be not easy breakage, and intensity height, it also has good sealing effect, wear-resistant, durable in use, on-deformable advantage.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment: present embodiment is made up of O shape steel ring 1, nitrile rubber circle 2.O shape steel ring 1 is arranged on the inside of nitrile rubber circle 2, and O shape steel ring 1 closely links into an integrated entity with nitrile rubber circle 2.The internal diameter A of nitrile rubber circle 2 is 34-42 centimetre, and the diameter of section B of O shape steel ring 1 is 2.4-3.2 centimetre, and the wall thickness C of nitrile rubber circle 2 is 0.9-1.4 centimetre.
Claims (2)
