Abstract
The utility model relates to a wellhead device for an oil pumping well, which comprises a base body, a lower flange and an upper flange. The utility model is characterized in that a passage communicated with an oil outlet pipeline through a sluice of an oil conduit is arranged on the upper part of the base body. The utility model has advantages of convenient underground operation, construction time saving, little component loss, little heat-insulating material loss and labor intensity reduction.
Description
The utility model relates to a kind of wellhead assembly of petroleum industry pumpingh well.
The existing pumpingh well wellhead assembly that is employed widely in petroleum industry comprises pedestal, lower flange, flexible flange, the upper flange of device, and the three-way pipeline that connects flowline is housed on upper flange.The wellhead assembly of this structure when carrying out underground work, need be dismantled more component, comprises flow line and lagging facility, waste time and energy, and fragile spare and accessory parts and lagging facility.
The purpose of this utility model provides a kind of novel pumpingh well wellhead assembly, and this wellhead assembly is only dismantled upper flange and got final product when carrying out underground work, need not remove component such as oil pipeline.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the structure chart of existing pumpingh well wellhead assembly.
1-sucker rod among the figure, 2-sleeve pipe, 3-lower flange, the 4-sleeve gate, 5-casing pressure table, 6-oil pipe, 7-" O " RunddichtringO, 8-tubing hanger, 9-jackscrew, 10-flow line and insulation layer, 11-oil pipe gate, 12-pedestal, the 13-upper flange, 14-blowout prevention box, the flexible flange of 15-, the 16-flow tee, the 17-gate.
The utility model comprises pedestal (12), lower flange (3), upper flange (13), lower flange (3) joint sleeve (2), upper flange (13) connects blowout prevention box (14), there is a passage to be connected with casing pressure table (5) through sleeve gate (4) in pedestal (12) bottom, other has a passage to be communicated with flow line (10) through gate (17), it is characterized in that: also have a passage to be communicated with flow line (10) through oil pipe gate (11) on pedestal (12) top. Pedestal (12) can be monolithic devices, also can be made up of upper and lower two parts, so that processing and manufacturing.
The utility model has the advantages that, only need shed upper flange can carry out underground work, and by common way, also must lay down the insulation layer on flow line and the pipeline simultaneously, thereby reduce the loss of component and heat insulating material widely, reduce the underground work cost, simultaneously because of loading and unloading facility, can shorten the time of underground work, enhance productivity, increase oil production rate.
Claims (2)
1, a kind of pumpingh well wellhead assembly, comprise pedestal (12), lower flange (3), upper flange (13), lower flange (3) splicing sleeve (2), upper flange (13) connects blowout prevention box (14), there is a passage to be communicated with casing pressure table (5) in pedestal (12) bottom through sleeve gate (4), other has a passage to be communicated with flow line (10) through gate (17), it is characterized in that: also have one or more passage to be communicated with flow line (10) through oil pipe gate (11) on pedestal (12) top.
2,, it is characterized in that by the described pumpingh well wellhead assembly of claim 1: what described pedestal (12) can monolithic devices, also can combine by upper and lower two parts.
