Abstract
The utility model relates to an injected polymer bridge type eccentric injection distribution device, mainly solving the problems that the existing injected polymer can not be matched with the existing test technology and the like. The injected polymer bridge type eccentric injection distribution device comprises a main body (1) and a plug assembly (9), wherein the main body (1) is provided with an eccentric through hole (2), an eccentric circular hole (3) and at least two through holes (4); the plug assembly (9) is arranged in the eccentric circular hole (3); the lower part of the plug assembly (9) is internally provided with a flow regulating sleeve (7) and a pressure adjusting sleeve (8); the wall of the main body (1) is provided with a liquid inlet (5) and a liquid outlet (6); and the eccentric circular hole (3) is respectively communicated with the liquid inlet (5) and the liquid outlet (6). The injection distribution device has a bridge type channel, leads the test at the layer not to influence normal injection of other layers, can realize direct test with layered flow rate and effectively reduce interlayer interference when in test; and layered pressure test does not use the retrievable injection distribution plug and the working state is not changed.
Description
Technical field:
The utility model relates to a kind of downhole tool used in the oil-gas field development field, belongs to a kind of polymer injection bridge-type eccentric injection allocation device.
Background technology:
For further improving oil recovery factor, tertiary oil recovery has become the important means of oil field development.Used polymer injection injection allocation device does not possess the passageway bridge function at present, incompatible with existing test technology on stratified flow rate test, in the little water injection well of multilayer and individual layer injection rate, there are allotment difficulty and zonal pressure test job amount is big, efficient is low, data is forbidden problem.
The utility model content:
In order to overcome the deficiency that background technology exists, the utility model provides a kind of polymer injection bridge-type eccentric injection allocation device, and this instrument can be realized section plane tests such as oxygen activation, correlative flow; Can realize the measuring point of electromagnetic flowmeter, obtain zonal flow rate, also can adopt testing seal section to realize the flow rate test of individual layer section simultaneously; This technical compatibility the general existing well layering test technology in oil field.Also have fixed tubular column simultaneously and can realize blank water drive, poly-driving and the advantage of follow-up water drive.
The technical solution of the utility model is: this polymer injection bridge-type eccentric injection allocation device comprises main body and blanking plug assembly, described main body has eccentric through-hole, eccentric circular hole and at least 2 through holes, the blanking plug assembly places in the eccentric circular hole, Flow-rate adjustment cover and pressure regulating sleeve are arranged in the blanking plug assembly bottom, have inlet opening and fluid hole on the main wall, eccentric circular hole communicates respectively with inlet opening and fluid hole.
The utlity model has following beneficial effect: owing to take such scheme, main body has eccentric through-hole, eccentric circular hole and through hole, can in eccentric circular hole, put the blanking plug assembly, when the test downhole data, to in centre bore, need not pull the blanking plug assembly out under the tester, it is convenient to compare existing process test, has reduced operation, has improved efficient.Because this injection allocation utensil has passageway bridge, the normal notes that do not influence other layer when this interval is tested are poly-, can realize that zonal flow rate directly tests the interlayer interference when effectively having reduced test; The zonal pressure test does not change duty without pulling injection allocation blanking plug.
