Abstract
The invention discloses a built-in type sampling device, and relates to an oilfield sampling device. The built-in type sampling device comprises a sampling casing pipe, wherein clamp heads are connected to two ends of the sampling casing pipe respectively; a three-way plug valve is fixed in the sampling casing pipe and comprises a valve body, a spherical valve core and a valve rod; a horizontal inlet, a horizontal outlet located on the same straight line with the horizontal inlet and a perpendicular outlet perpendicular to the horizontal inlet are formed in the valve body; the horizontal inlet and the horizontal outlet of the three-way plug valve are coaxial with the sampling casing pipe; and the perpendicular outlet of the three-way plug valve is connected with a sampling nipple outward extending out of the sampling casing pipe. The three-way plug valve adopts the built-in type, a better heat insulation effect is achieved, the sampling nipple is arranged perpendicularly, after sampling is finished, the inside of the sampling nipple is free of residues, and frozen blockage is avoided.
Description
Technical field
The present invention relates to a kind of oil field sampler, be specially a kind of built-in sampler.
Background technology
Well mouth of oil well sample cock is mounted in the vertical pipeline of Well head flow path place at present, and in winter, sampling pipe nipple and valve position be frozen block especially easily, and wellhead oil sample is very difficult.Secondly, in tradition sampling, exist Well head flow path and make and non-standard phenomena is installed, cause oil sample to represent that authenticity is poor, directly affect the degree of accuracy of well water assay.In addition, anyone can both open on-the-spot sample cock with handwheel or spanner, and non-anti-theft, easily suffers malicious sabotage, makes enterprise suffer unnecessary economic loss.
Summary of the invention
The object of this invention is to provide a kind of certain anti-theft feature that has, and can avoid the built-in sampler that winter, frozen block occurred.
The technical scheme that realizes above-mentioned purpose is: built-in sampler, it is characterized in that: comprise drive pipe, the two ends of drive pipe are jointing clip head respectively, in drive pipe, be fixed with threeway plug valve, threeway plug valve comprises valve body, spherical valve core and valve rod, on described valve body, be provided with horizontal inlet, Horizontal Exit with horizontal inlet on same straight line and the vertical outlet vertical with horizontal inlet, the level of threeway plug valve is entered, outlet and drive pipe coaxial line, the vertical output mouth of threeway plug valve is connected with sampling pipe nipple, the protruding drive pipe of sampling short circuit.
The entrance point of above-mentioned threeway plug valve connects and converges oily oviduct, converge oily oviduct big opening end outwardly.
In above-mentioned valve body, be provided with spherical valve core, on described spool, be provided with the T shape circulation passage coordinating with horizontal inlet, Horizontal Exit and the vertical outlet of valve body, by rotational valve core, come the connection between the horizontal inlet of Horizontal Exit, vertical outlet and valve body of application valve body to switch, on described spool, be fixed with valve rod, valve rod extends to outside drive pipe, described valve rod is arranged with sleeve pipe outward, one end of sleeve pipe is fixedly connected with valve seal, other end sealing passes drive pipe, and the free end of described valve rod is provided with antitheft raised line or groove; Described threeway plug valve also comprises the key with the antitheft raised line in valve rod outer end or groove fit.
The present invention is arranged between production tree and resistance oil nozzle sleeve, and sampling short circuit arranges vertically downward.
Beneficial effect of the present invention:
1, threeway plug valve employing of the present invention is built-in, has good heat insulation effect, and sampling short circuit vertically arranges, and after having sampled, in sampling pipe nipple, does not stay remnants, has avoided the generation of frozen block.
2, the valve rod outer end of threeway plug valve is provided with antitheft raised line or groove, needs private key just can carry out switch, has certain anti-destruction, and the function of anti-pilferage has been avoided the stolen economic loss causing of crude oil.
3, the present invention has increased sample tap cross section by converging oily oviduct, and when sampling oil stream is from converging continual flowing in oily oviduct, sample goes out from just pumping in pit shaft, avoid the analysis data distortion causing because oil sample is inaccurate, for accurately enrolling the effective dynamic data of oil well, provide assurance.
Accompanying drawing explanation
