Abstract
A wellhead guide oil nozzle of a flowing well is applied to oil extraction of the flowing well in an oil field. The novel oil-water separator mainly comprises an outer hexagonal cylinder, an outer threaded cylinder and a cone, wherein the outer hexagonal cylinder is connected with the outer threaded cylinder relatively, the central line of the outer hexagonal cylinder and the central line of the outer threaded cylinder are the same straight line, the outer hexagonal cylinder and the outer threaded cylinder are provided with central holes, the central holes are flow passages for spraying crude oil, the cone is connected to the end part of the outer threaded cylinder, the cone is provided with a central hole, and the central hole of the cone is communicated with the central hole of the outer threaded cylinder. The effect is as follows: the oil nozzle is convenient to install, the operation of workers is facilitated, and the labor intensity of the workers is reduced. And forced well shut-in accidents caused by unsuccessful installation of the oil nozzle are reduced by 80 percent.
Description
Technical field
The utility model relates to flowing well oil recovery technique field, oil field, and particularly a kind of flow bean is the special-purpose oil nozzle easy for installation that a kind of end has tapering.
Background technology
In the field control of oil field whale, the oil recovery worker changes, checks, oil nozzle is installed is a regular job, and there is following problem in the oil nozzle of whale well head in installation process:
A: the installation of oil nozzle is finished with the oil nozzle special sleeve spanner, oil nozzle is fixed to the special sleeve spanner end, utilize special sleeve spanner that oil nozzle is sent into and be installed in the well head nozzle cage, the holder depth of nozzle cage reaches more than the 400mm, and the internal diameter of nozzle cage is 50mm; People's naked eyes can't be observed when mounted, just rely on employee's feel, and the external screw thread of oil nozzle and the internal thread of nozzle cage holder are carried out the make-up operation, have increased the field control difficulty.
B, in the installation process of oil nozzle because nozzle cage holder internal thread is because of the influence of factors such as sand, wax, difficulty strengthens during the oil nozzle make-up.In the time can't finishing installation, can only employ electrogas welding the well head nozzle cage is changed, reduced the flowing well well opening time, both influenced oil well output.
The utility model content
The purpose of this utility model is: a kind of flowing well well head guiding oil nozzle is provided, is convenient to install oil nozzle, made things convenient for employee's operation, reduce staff labor intensity.
The technical solution adopted in the utility model is: flowing well well head guiding oil nozzle, mainly form by outer hexagonal prism body, external screw thread cylinder and cone, outer hexagonal prism body is relative with the external screw thread cylinder to be connected, outer hexagonal prism body center line and external screw thread cylinder center line are same straight line, outer hexagonal prism body and external screw thread cylinder have centre bore, centre bore is the runner of crude oil ejection, it is characterized in that: the end of threaded circular cylinder is connected with a cone outside, cone has centre bore, and the cone centre bore is communicated with external screw thread cylinder centre bore.
On the outer wall between hexagonal prism body and the external screw thread cylinder, an annular baffle that outwards protrudes is arranged outside.After tightening oil nozzle, the end face of baffle plate and the holder end face of nozzle cage are overlapping, play spacing and sealing function.
The tapering of described cone is 60 degree.
The use of summary flowing well well head guiding oil nozzle.Consult Fig. 1.The end that the outer hexagonal prism body 4 of flowing well well head guiding oil nozzle is inserted special sleeve spanners 2.Utilize special sleeve spanner 2 that oil nozzle is sent in the nozzle cage 1.The cone 6 of oil nozzle has guide effect, can insert easily in the fixing threaded hole 7 of nozzle cage 1.Rotation special sleeve spanner 2 screws in external screw thread cylinder 5 in the fixing threaded hole 7 of nozzle cage 1.Tighten nozzle, finish installation.
The beneficial effects of the utility model: the utility model flowing well well head guiding oil nozzle, the cone of oil nozzle has guide effect, is convenient to install oil nozzle, has made things convenient for employee's operation, reduces staff labor intensity.Reduce 80% because of the oil nozzle installation gets nowhere, cause the closing well accident of being forced to.
Description of drawings
Fig. 1 is that the utility model flowing well well head guiding oil nozzle is installed generalized section.
Among the figure, 1. nozzle cage, 2. special sleeve spanner, 3. baffle plate, 4. outer hexagonal prism body, 5. external screw thread cylinder, 6. cone, 7. fixing threaded hole.
The specific embodiment
Embodiment 1: with a flowing well well head guiding oil nozzle is example, is described in further detail.
Consult Fig. 1.The utility model flowing well well head guiding oil nozzle, mainly form by outer hexagonal prism body 4, external screw thread cylinder 5 and cone 6, outer hexagonal prism body 4 and the 5 relative connections of external screw thread cylinder, outer hexagonal prism body 4 center lines and external screw thread cylinder 5 center lines are same straight line, and outer hexagonal prism body 4 and external screw thread cylinder 5 have the centre bore of a 8mm.On the outer wall between hexagonal prism body 4 and the external screw thread cylinder 5, it is the annular baffle 3 of 4mm that a thickness that outwards protrudes is arranged outside.The end of threaded circular cylinder 5 is connected with a cone 6 outside, and the tapering of cone 6 is 60 degree.Cone 6 has the centre bore of 8mm, and cone 6 centre bores are communicated with external screw thread cylinder 5 centre bores.
