Abstract
The utility model relates to a down-hole-eccentric water-distribution quantity plug the utility model is composed of a valve rod 8, a valve seat 10, a damping ceramic chip assembly 12, a gap adjusting gasket 11, a spring 5, a gasket 3, a spring clamping ring 2, a press cover 6, a sliding seal assembly 7, a sealing ring 9 and a casing 4. The utility model is of the same shape with the original plug, is of the same throwing and fetching working tool and device with the original plug, each layer only needs one time throwing and fetching, and the down-hole-eccentric water-distribution quantity plug has the labor saving and time saving performance. Because of the actual water injection quantity, the down-hole-eccentric water-distribution quantity plug is free from the external interference, and the stable water injection can be ensured.
Description
The utility model is that the water filling engineering in the crude oil manufacturing process is allocated a kind of down-hole eccentric center water-distributing constant flow blanking plug of the water yield with the down-hole eccentric center water-distributing.
To different oil-bearing stratum flooding the time, can control each layer injected water volume, the water yield of each layer injection is remained in the scope of engine request, and a kind of down-hole eccentric center water-distributing constant flow blanking plug of the influence not different with the well tubing string degree of depth with strata pressure, that the surface water supply equal pressure changes.
The purpose of this utility model be designed down-hole eccentric center water-distributing constant flow blanking plug can adapt to by its water quality clean inadequately, the oil reservoir difference is big, import and export pressure has under the bigger variation, the water yield that can keep injecting oil reservoir is constant in the scope that requires, operate as normal and possessing the suitable life-span in the environment of strong erosion, cavitation erosion, sand milling.
The utility model achieves the goal by following technical solution: down-hole eccentric center water-distributing constant flow blanking plug is mainly by valve rod 8, valve seat 10, damping ceramics assembly 12, transfer crack packing ring 11, spring 5, packing ring 3, spring collar 2, gland 6, slipper seal assembly 7, sealing ring 9, housing 4, constitute, valve rod 8, no seal groove, the lower end is a cone, top is cylinder, spring 5, one end is supported in housing 4, the other end is supported on by spring collar 2, packing ring 3, the valve rod 8 that blocks, the upper end makes valve rod 8, upwards held out against, valve rod 8, the bottom be valve seat 10, be the hollow cylinder ceramic materials, its upper end endoporus is the enlarging taper seat, it by other part jam-packed of its underpart in housing 4, endoporus step place, at valve seat 10, below be to transfer crack gasket assembly 11, and damping ceramics assembly 12, wherein, transfer crack gasket assembly 11, for omiting softwood matter annulus, damping ceramics assembly 12, be the ceramic disks of different diameter of bores, two groups of assemblies pressure cap 13 of being intake, compress.
The utility model also achieves the goal by following technical solution: spring 5, can have different coupling rigidity and starting force, accent crack gasket assembly 11, and damping ceramics assembly 12, various combination, valve rod 8, lower end cone different coning angles, all different combinations can be arranged, and form different series, specification and linear condition and deviation.
The utility model profile is identical with former blanking plug, and pulling power tool, equipment are identical, and every layer only needs pulling once, the saving of labor, save time, thereby because actual water injection rate is not subjected to external interference can guarantee that water filling is stable,
Accompanying drawing is structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model with housing 4, make an integral body, its inside has not only been installed above-mentioned major part the salvaging assembly also has been housed at an upper portion thereof, middle part supporting valve rod 8, simple in structure, good rigidly, help valve rod 8, with valve seat 10, the disalignment error reduce, useful for the reliability and the sensitivity that improve valve rod 8, action and since delivery port only open housing 4, on make water outlet more unobstructed.Because water inlet place adopt to be transferred crack gasket assembly 11, and damping ceramics assembly 12, scratched stream with damping repeatedly and can make the inlet opening obtain strengthening, and is difficult for blocking dirt, handling capacity strengthens, and adopts slice structure to make things convenient for allotment to make up.Valve rod 8, no sealed groove, simple in structure, rigidity helps its slip in housing 4, endoporus greatly.Gland 6, with sliding seal 7, press valve rod 8, cylindrical and housing 4, the upper end on the hole end surface, make valve rod 8, cylindrical and housing 4, the endoporus fitting face on the not beneficial dirt that enters rub and also reduce.Valve rod 8, and valve seat 10 between initial opening help terrestrial operation more greatly and untie big dirt and stop up.
