The invention relates to oilfield equipment for sampling for analysis at the mouth of oil wells and can be used for integrated sampling multicomponent gas-liquid systems, transported through pipelines.

On the constructive and functional characteristics of the closest analogue is a sampling device (patent RU 2151290 G 1), inside which is the body control the flow of multicomponent gas-liquid environment, equipped with sealing elements, select the camera in the form of sealed spherical segment with intake channels, the locking body with the guide tube, the valve of the sampling set with the ability to interact with a spring-loaded rod.

The body of the flow control and shut-off body are driven individually by separate arms in a certain sequence.

The disadvantages of the known devices is the complexity of the design, which increases its cost and operating costs, complicates maintenance. The control flow is driven through the shaft with Salnikov seal, want to strictly follow:

a) periodically re-tighten the packing to prevent leakage;

b) at least wear add seals or replace a new set, due to the stop of the well, a violation of ecology at the wellhead, etc.

There is a danger that distant from the main flow of process fluid parts like the stem, the spring can "grab" the frost, as in the oil composition may be water and the device will heat up during sampling. In addition, the process of sampling the space intended for the movement of the process stream, is completely blocked by the governing body of this thread. Luggage sampling intensively filled multicomponent gas-liquid mixture (process stream) and splits because the traffic flow was noticeably lessened and the entire process of sampling depends on the human factor, how to correctly and clearly the actions of the operator. In this regard, is no guarantee of obtaining samples with objective value components.

The technical problem solved by the invention is to simplify the design and maintenance, improving device reliability and quality of sampling multicomponent gas-liquid environment.

This object is achieved in that the sampling device for integrated sampling multicomponent gas-liquid medium containing installed in the pressure pipe of the hollow body inside which races halogen rotary body control the flow of multicomponent gas-liquid medium, the camera selection with the inlet channels, the locking body located within the housing actuated valve sampling, the guide tube, it includes a hollow body in the form of a fragment of the discharge pipe, the body control the flow of multicomponent gas-liquid medium located in the hollow body and comprising installed on the damper shaft with a diameter corresponding to the inner diameter of the hollow body, the camera selection and mixing of the flow of multicomponent gas-liquid medium in the form of an annular cavity in the hollow body divided situated at the level of the valve partition on the input and output parts, communicated with the General flow of multicomponent gas-liquid environment through respectively the inlet and outlet channels on the hollow body and through the passage provided in the partition wall inlet valve sampling, and installed in the valve housing authority of the drive screw is connected to the valve sampling rotatably relative to each other and joint axial movement, and the valve of the sampling and the shaft with the damper associated with synchronous limited rotation around a common axis and relative axial movement.

1 shows a section along the line A-a in figure 2; figure 2 is a section along the line B-B in figure 1; figure 3 is a section along the line b-b In figure 2.

P is aboutmore device (hereinafter, the device contains a hollow body 1 (figure 1), representing a fragment of the discharge pipe located indifferent towards the earth's surface. The body control the flow of multicomponent gas-liquid medium is made in the form mounted on the shaft 2 of the valve 3 with a diameter corresponding to the inner diameter of the hollow body 1. At the level of the valve 3 from the outside of the hollow body 1 provided camera selection and mixing 4 case 5 (figure 1), divided in half by a partition 6 to input 7 and output 8 of part (2)provided with a common flow of multicomponent gas-liquid medium respectively through the inlet 9 and outlet 10 channels on the hollow body 1 and through the passage 11 (figure 3)provided in the partition 6 at the entrance to the valve sampling 12.

In the boss 13 is set to saddle 14 valve gasket 15, is fixed by means of the Union nut 16 through the housing 17 of the valve 12 with the guide tube 18 (Fig 1). The rear end of the valve sampling 12 is arranged to interact with a drive screw 19 through the annular ledge 20 (1,3). The other end of the valve 12 (Fig 1) is connected with the shaft 2 by means of the spline (see extension section to the right, figure 1), and the shaft 2 with the flap 3 is set in relation to the hollow body 1 with a limited rotation (90°) thanks to Cam with whom the Association, provided at the other end of the shaft 2 (see extension section to the left, figure 1).

The device operates as follows. When the open position of the valve 3 valve sampling 12 is closed, which corresponds to the initial position. The flow of multicomponent gas-liquid medium mainly passes directly through the hollow body 1 (Fig 1). However, it is possible that some part of this medium through the inlet 9 and outlet 10 channels (figure 2)and also through the passage 11 (Fig 3) may be in a roundabout way, though, and the valve 3 is open, that way, and has no effect.

Before sampling, you must install the appropriate receptacle (not shown) under the guide tube 18 (Fig 1). Rotate the drive screw 19 on the top, while the first valve sampling 12 being pressed against the end face of the drive screw 19 with its annular ledge 20 under the action of pressure from the side selected for the sample environment will rotate 90°, pulling and shaft 2 with the valve 3 through a splined connection, and will occupy a closed position 21 (Fig 1). Upon further turning of the drive screw 19, the valve 12 moves away from the seat 14, creating conditions for sampling, in which the selected mixture passing from the input part 7 through the inlet channels 9 and passage 11 (Fig 3), while mixed, concentrating directly in front of the valve of the sample 12, and through the latter falls into the selected container. A portion of the mixed multi-component gas-liquid mixture flowing through the passage 11, enters the output part 8 camera selection and mixing and through the outlet channels 10 is fed again in the hollow body, which creates the right conditions for the passage of process fluid in the process of sampling.

After sampling the required amount of drive screw 19 is rotated to close. First of all, the valve 12 with the shaft 2 and the valve 3 rotates 90°i.e. from position 21 is returned to its original position (figure 1). Further rotation of the drive screw 19 causes the valve of the sample 12 in the forward motion that completes its closing. At this time provided at the end of the shaft 2 Cam connection prevents further rotation of the valve 3 and the valve 12 relative to the shaft 2 makes the axial displacement due to the spline connection and a joint with a drive screw 19 axial movement. Taken sample is sent for analysis.

Upon completion of the work is checked the position of the valve 3 through the opening 22 at the rear end of the valve sampling 12 as the valve 3, the hole 22 is located in the same plane. If for any unforeseen circumstances flap 3 remained closed, pre-relaxation and loosening of the drive screw 19, the valve 12, clutching his hole 22, neobhodimosti before the opening of the valve and tighten the drive screw completely.

Due to the constructive solution is achieved compactness, simplicity of the device, and laid the scheme of mixing of multicomponent gas-liquid environment, using the kinetic energy of the flow, allows to achieve a high-quality mix of product selection, simplifies the technology of sampling, regardless of the human factor. Valve pair is located in the immediate vicinity of the main process stream, which eliminates the chance of freezing in the winter.
