Description
Technical field
The utility model is the wellhead assembly of oil field pumping well, for the double-deck black soy sauce pumpingh well, specifically a kind of bilayer
A point pumping for pumpingh well separates wellhead assembly.
Background technique
Most of bilayer oil pumping is that black soy sauce mixes, and exactly two layers are lifted after being mixed on pump by the oil liquid that two pumpings go out
It is raised to ground, one of flowline is only needed on its pump.This fuel-displaced mode cannot analyze the yield of single layer, aqueous, crude oil object
Property, accurate data cannot be provided for oil field development, be also only suitable for the well that two layers are all pumped with oil well pump, be not suitable for oil well pump
With the pumpingh well of electric pump co-production.Bilayer oil pumping also has black soy sauce to separate down-hole string structure, in its two oil discharge passages,
One channel is to pump upper flowline, another channel is the circular passage pumped between upper flowline and well wellbore, this black soy sauce
Double tubular column structures out need that the hydrodynamic face of oil well, oil jacket cannot be surveyed in underground tripping in packer sealing oil casing annular space
Pipe annular space is fuel-displaced to be also easy to that casing is caused to damage, and shortens the service life of oil well, is also only suitable for two layers and all uses oil well pump
The well of oil pumping is not suitable for the pumpingh well of oil well pump and electric pump co-production.The appearance of the above problem is because without suitable double
Caused by taking out double wellhead assemblies out.
Summary of the invention
The purpose of this utility model is to design a kind of point taking out for dual pumping well to separate wellhead assembly, realizes the double-deck oil pumping point
Layer is fuel-displaced, and can overcome the problems, such as above-mentioned, is able to achieve electric pump, oil well pump is pumped jointly, and meet that high output of oilwell point takes out wants
It asks.
Purpose of the utility model is realized as follows: include pumping rod sealer, upper flow tee, lower flow tee,
Interior flowline, hanger, well head four-way, lower flange, outer flowline, lower flange are connected on oil well casing, the installation of well head four-way
On lower flange, in outer flowline lower going-into-well mouth four-way, lower flange, well head is suspended on after the top connection hanger of outer flowline
On four-way, the lower part of outer flowline is in oil well casing, and the lower part of lower flow tee is mounted on well head four-way, under fuel-displaced three
It is connected with side port, flow tee under interior flowline tripping in, hanger, in outer flowline, the top of interior flowline is connected to out
After in oily threeway lower part, the lower part of flow tee is mounted on lower flow tee, and flow tee has side port, pumping rod sealer
It is mounted on flow tee, has upper cable penetration hole on lower flow tee, there is lower cable penetration hole on hanger.
Fuel-displaced valve is installed on the side port of upper flow tee, and lower delivery valve is installed on the side port of lower flow tee
Door.
The beneficial effects of the utility model are: oil well pump is installed in the lower part of interior flowline, the oil liquid of a layer is taken out, it is outer fuel-displaced
Electric pump is installed in the lower part of pipe, takes out the oil liquid of a layer, and the cable that electric pump uses can be attached to outside outer flowline, and can be by described
Lower cable penetration hole, upper cable penetration hole be pierced by, oil well pump extraction oil liquid from the side port of upper flow tee flow out, electric pump
The oil liquid of oil pumping is flowed out from the side port of lower flow tee, and point pumping for being able to achieve electric pump and oil well pump separates, and overcomes existing
Technology there are the problem of, be able to satisfy the requirement that high output of oilwell point is taken out, there is significant economic benefit.
