Abstract
The utility model discloses a crude oil sampling device, which is applied to collection of a crude oil sample inside an oil well or on a well mouth pipeline. The device is characterized in that a valve is fixed to the upper part of an oil inlet pipe. An unloading cylinder is fixed to an end part of the oil inlet pipe. A sampling mouth and a rubber sealing ring are arranged inside the unloading cylinder. An unloading pipeline is fixed to an outer wall of the unloading cylinder. The unloading pipeline is connected with an atmospheric valve. The oil inlet pipeline is also fixed to an upper tray which is provided with two holes. A pull rod is respectively positioned in the holes. Threads are respectively provided on the two ends of the pull rod. A lower tray respectively is fixed to the lower ends of the two pull rods. A spring is sleeved on the upper end of each pull rod. The spring is positioned at the upper part of the upper tray. A gasket and a press cap are fixed to the upper end of the pull rod. The device has the advantages that the device can collect the sample of the crude oil; the sampled quantity can be observed; pressure concentration and bottle exploding can be prevented; the sealing effect is good; and the problem that surplus crude oil disturbs the sample does not occur.
Description
Technical field
The utility model relates to technical field of petroleum extraction, gathers the sampler of crude oil sample on the indoor or well head pipeline of particularly a kind of oil well.
Background technology
At present, what the sampling of the oil well in oil field was adopted is wellhead sampling and two kinds of methods of indoor sampling, and there is oil sample splash phenomenon in wellhead sampling, the sample error that obtains is bigger, the sampling qualification rate is low, is unfavorable for environmental protection, exists to be unfavorable for numerous deficiencies such as safety, health; Though and the method that adopts indoor sampling can be improved the shortcoming of outdoor wellhead sampling effectively, exist can not observation sample quantity, can not effectively control sampling amount, thereby cause in the emptying tube residual crude oil is arranged, form the problem of sample phase mutual interference easily.
The utility model content
The purpose of this utility model is: a kind of crude oil sampling device is provided, and the natural-gas that produces when utilizing the return visit pipeline to take a sample drains into outside the sampling bottle, can take a sample under safe and reliable condition, can Real Time Observation and control crude oil sampling quantity.Overcoming in the existing sampler oil drum has residual crude oil, easily forms the problem that sample disturbs.
The technical solution adopted in the utility model is: the crude oil sampling device mainly is made up of emptying tube, sampling mouth, rubber seal, blow-down pipe and sampling pallet.Be fixed with valve on feed line top, the feed line end is fixed with the emptying tube.Sampling mouth and rubber seal are arranged in the emptying tube.On the outer wall of emptying tube, be fixed with blow-down pipe, be connected with atmospheric valve on the blow-down pipe.Open atmospheric valve, the natural gas in the emptying tube can obtain discharging by blow-down pipe, prevents that natural gas is in indoor gathering.
Also be fixed with top tray on feed line, top tray has two holes, and a pull bar is arranged respectively in the hole.There is screw thread at the two ends of pull bar.The lower end of two pull bars is fixed with down pallet.The upper end of pull bar is with spring, and spring is on the top of top tray.The upper end of pull bar is fixed with pad and pressure cap.
The crude oil sampling device is installed in going up under the sampling gate of crude oil flow process pipeline, and connects blow-down pipe and get final product.During use, sampling bottle is placed on down on the pallet,, the bottle neck of sampling bottle tightly is pressed on the rubber seal because spring upwards spurs pull bar.Open atmospheric valve, control sampling gate carries out sampling operation.The crude oil sample that the sampling mouth flows out can flow into sampling bottle.Because the pulling of the pulling force of spring is pallet down, and sampling bottle is securely fixed in down between pallet and the rubber seal.
The beneficial effects of the utility model: the utility model crude oil sampling device can be taked crude oil sample under the sampling gate of crude oil flow process pipeline.Sampling amount can directly be observed from the sampling bottle of glass.Because the existence of safety spring, the crude oil sampling device can prevent to build the pressure, bottle explosion, utilizes rubber seal can reach the purpose of airtight sampling, is fit to very much the technical requirements of indoor sampling.Because blow-down pipe is arranged, the natural gas that will produce in the time of can will taking a sample by blow-down pipe drains into outdoor, has prevented natural gas in indoor gathering, owing to removed the oil storage tank in the former sampling flowsheet, so there is not residual crude oil disturbed specimen problem.

The specific embodiment
Embodiment 1: consult Fig. 1.The crude oil sampling device mainly is made up of emptying tube 3, sampling mouth 4, rubber seal 6, blow-down pipe 5 and sampling pallet.Be fixed with valve on feed line 1 top, feed line 1 end is fixed with emptying tube 3.The diameter of emptying tube 3 is 50 millimeters, and length is 140 millimeters.Sampling mouth 4 and rubber seal 6 are arranged in the emptying tube 3.On the outer wall of emptying tube 3, be welded with a blow-down pipe 5, be connected with atmospheric valve on the blow-down pipe 5.
On feed line 1, be fixed with a top tray 2.Top tray 2 is a circular sheet, and diameter is 110 millimeters.There are two holes at top tray 2 edges, and a pull bar 8 is arranged respectively in the hole.The diameter of pull bar 8 is 8 millimeters, and length is 375 millimeters.There is screw thread at the two ends of pull bar 8.The lower end of two pull bars 8 is fixed with a following pallet 9.The shape of following pallet 9 is identical with top tray 2.The upper end of pull bar 8 is with a compression spring 11 respectively, and spring 11 is on the top of top tray 2.The upper end of pull bar 8 is with a pad 12 simultaneously, and screws with pressure cap 13 on spring 11.
When needs are taked crude oil sample, the bottleneck of sampling bottle 7 is aimed at sampling mouth 4.Sampling bottle is placed on down on the pallet 9.Open the atmospheric valve on the blow-down pipe 5, the valve on the control feed line 1 is taken a sample.Sampling amount can directly be observed from the sampling bottle of glass.Because the existence of spring, sampler can prevent to build the pressure, bottle explosion, utilizes sealing ring can reach the purpose of airtight sampling.The crude oil sampling device volume is less relatively, is fit to very much the technical requirements of indoor sampling.
At 36,35,32, No. 33 measuring stations of oil recovery one team in 2007, through the inferior indoor sampling of 1547 wells, 52 times outdoor sampling test.This device is compared with the indoor sampling method of routine in process on probation, on average saves sample time 70%, and the sampling qualification rate has improved 25%.In sampling process, detect good seal at sampling mouth place through the flammable pernicious gas detector of XP-311A type.
This device security performance is good, and simple installation, easy to use has alleviated working strength of workers greatly, has been subjected to operator's on probation favorable comment.
