Abstract
The utility model relates to the technical field of oil field samplers and discloses an oil sampler for an oil field. The oil sampler comprises a valve body, a sealing rod and a protective rod, wherein an axial through hole is formed on the valve body; a radial through hole which is communicated with the axial through hole is formed on the valve body; a plug is fixedly arranged in the radial through hole; the upper end of the axial through hole is of a frustum shape with a wide top and a narrow bottom; the outer diameter of the sealing rod is smaller than the diameter of the axial through hole; the lower end of the sealing rod is provided with a boss; the boss and the lower end of the valve body are fixed together through a thread; the protective rod of which the outer diameter is greater than that of the sealing rod is fixed at the upper end of the sealing rod; and the lower end of the protective rod is of a frustum shape which corresponds to the upper end of the axial through hole and has a wide top and a narrow bottom. The oil sampler is reasonable and compact in structure and convenient to use, and the protective rod is arranged on the sealing rod of the oil sampler, so that sand grains directly impact the protective rod, and the sealing rod of the oil sampler is protected; and therefore, the cost is greatly reduced.
Description
Technical field
The utility model relates to oil well sampler technical field, is a kind of oil field oil sampling device.
Background technology
Sampler is installed on the production plug of oil well, and it has sample circuit and does stifled first two function, because sampler is simple in structure, easy to operate, in viscous crude is produced, generally uses.But because that viscous crude is taken is husky very capable, the production well ubiquity goes out husky situation; Under the notes way of steam that viscous crude is produced, make the strata pressure of oil well than higher, the grains of sand impact production flow line under the effect of pressure; Will certainly cause production flow line to be punched with the rigid material that contacts; The situation that the spool of sampler is punched is commonplace, is punched because of the sampler spool and causes viscous crude to reveal pollution, and the viscous crude that pollutes is revealed in cleaning has increased producing cost.
Summary of the invention
The utility model provides a kind of oil field oil sampling device, has overcome the deficiency of above prior art, and it can solve effectively that the grains of sand puncture the spool of sampler and the problem that causes the viscous crude leakage pollution.
The technical scheme of the utility model realizes like this: a kind of oil field oil sampling device comprises valve body, seal bar and guard bar; Axially extending bore is arranged on valve body; The radial direction through hole that communicates with axially extending bore is arranged on valve body; In radial direction through hole, be installed with plug, the upper end of axially extending bore is taper type wide at the top and narrow at the bottom, and the external diameter of seal bar is less than the diameter of axially extending bore; There is boss the lower end of seal bar; Boss is fixedly installed togather through the lower end of screw thread and valve body, is fixed with the guard bar of external diameter greater than the seal bar external diameter in the upper end of seal bar, and the lower end of guard bar is and the corresponding taper type wide at the top and narrow at the bottom in axially extending bore upper end.
Above seal bar and guard bar are fixedly installed togather through screw thread.
The middle part diameter of above axially extending bore is greater than the diameter of axially extending bore top and axially extending bore bottom, and radial direction through hole is connected with the middle part of axially extending bore.
The O RunddichtringO is installed between the bottom of above axially extending bore and the seal bar.
The lower end of above seal bar is installed with square head.
The utility model reasonable and compact in structure, easy to use, through on the seal bar of sampler, installing guard bar additional, thereby make the grains of sand directly impact the seal bar that guard bar has been protected sampler, so just greatly reduced cost.
Description of drawings
Fig. 1 looks the broken section structural representation for the master of the utility model when opening.
Coding among the figure is respectively: 1 is valve body, and 2 is seal bar, and 3 is guard bar, and 4 is axially extending bore, and 5 is radial direction through hole, and 6 is plug, and 7 is boss, and 8 is the O RunddichtringO, and 9 is square head.
The specific embodiment
As shown in Figure 1, a kind of oil field oil sampling device comprises valve body 1, seal bar 2 and guard bar 3; Axially extending bore 4 is arranged on valve body 1; The radial direction through hole 5 that communicates with axially extending bore 4 is arranged on valve body 1; In radial direction through hole 5, be installed with plug 6, the upper end of axially extending bore 4 is taper type wide at the top and narrow at the bottom, and the external diameter of seal bar 2 is less than the diameter of axially extending bore 4; There is boss 7 lower end of seal bar 2; Boss 7 is fixedly installed togather through the lower end of screw thread and valve body 1, is fixed with the guard bar 3 of external diameter greater than seal bar 2 external diameters in the upper end of seal bar 2, and the lower end of guard bar 3 is and the corresponding taper type wide at the top and narrow at the bottom in axially extending bore 4 upper ends.Like this, when sampler cut out, the lower end of guard bar 3 and axially extending bore 4 upper ends were sealed and matched; The grains of sand impact guard bar 3 under the effect of pressure; Thereby guard bar 3 is worn and has protected seal bar 2, because the cost of sampler is much larger than the cost of guard bar 3, after guard bar 3 may wear to the limit; Change guard bar 3 and get final product, so just greatly reduced cost.
As shown in Figure 1, for the ease of installation and removal, seal bar 2 and guard bar 3 are fixedly installed togather through screw thread.
As shown in Figure 1, the middle part diameter of axially extending bore 4 is greater than the diameter of axially extending bore 4 tops and axially extending bore 4 bottoms, and radial direction through hole 5 is connected with the middle part of axially extending bore 4.Like this, oil volume, be convenient to viscous crude and flow out sampler owing to increased.
As shown in Figure 1, in order to increase sealing, between the bottom of axially extending bore 4 and the seal bar 2 O RunddichtringO 8 is installed.
As shown in Figure 1, for the ease of opening, the lower end of seal bar 2 is installed with square head 9.
