Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to an oilfield development sampling device. Background Art

[0002] In the process of oilfield exploitation, sampling and analysis of formation crude oil is an important step in evaluating oilfield production, oil quality, and formulating subsequent exploitation strategies. However, in the initial sampling period, when crude oil is lifted from deep underground (high pressure, high temperature environment) to the surface (normal pressure, normal temperature environment), the natural gas dissolved in the crude oil will precipitate due to the pressure reduction, which makes the crude oil relatively more viscous and has poor fluidity. This leads to uncertainty in the initial samples collected, affecting the results of the evaluation and detection, and cannot truly reflect the actual condition of the formation crude oil. At present, the existing sampling devices cannot directly separate or separate the initial oil and the middle oil. The initial oil needs to be drained before sampling can be performed. The operation process is relatively complicated and inconvenient to use.

[0003] In order to solve the above problems, we propose an oilfield development sampling device that can directly separate the initial oil and the middle oil to ensure the accuracy of the sampling results. Utility Model Content

[0004] In order to overcome the disadvantages of the existing sampling device that the initial oil and the middle oil cannot be directly separated or divided and the initial oil needs to be drained before sampling, the utility model provides an oilfield development sampling device.

[0005] An oilfield sampling device comprises a base, a mounting frame slidably connected to the top of the base, a supporting frame fixedly connected to the mounting frame, the supporting frame and the base are slidably connected, an oil drain pipe is fixedly connected to the top of the supporting frame, an oil filling cylinder is fixedly connected to the supporting frame, the oil drain pipe is communicated with the oil filling cylinder, the top of the oil filling cylinder is communicated with an oil receiving pipe, an electric push rod is fixedly connected to the mounting frame, a piston is slidably connected in the oil filling cylinder, the telescopic end of the electric push rod is connected to the piston, the bottom end of the oil filling cylinder is communicated with an electric valve, the telescopic end of the electric push rod is fixedly connected to a touch handle, the touch handle is extrusion-fitted with the electric valve, an adjusting component for adjusting the height of the oil receiving pipe is provided between the base and the mounting frame, and a placing component for placing a filling container is provided on the base.

[0006] Further description: the bottom end of the base is rotatably connected to rollers that are equidistantly distributed.

[0007] Further description: A handle is fixedly connected to the mounting frame.

[0008] Further explanation: a valve is installed on the oil discharge pipe.

At the same time, the handle presses the electric valve to open, and the middle oil transported into the oil filling cylinder by the oil receiving pipe can flow into the containing container through the electric valve. In this way, the initial oil and the middle oil can be directly separated to ensure the accuracy of the sampling result.

[0012] 2. The threaded rod rotates to control the nut to move up and down, and then the height of the oil pipe connected to the mounting bracket is adjusted so that the oil pipe is flush with the oil outlet for easy connection.

[0020] When using the device, the staff moves the device to a suitable position, then places the container on the placement component, and then adjusts the height of the oil receiving pipe 5 through the adjustment component to make the oil receiving pipe 5 flush with the oil outlet. Then the staff pushes the device to move by the handle, and the roller can facilitate the movement of the device on the ground. When the oil receiving pipe 5 moves to dock with the oil outlet, the crude oil in the oil outlet enters the oil filling cylinder 4 through the oil receiving pipe 5. When the initial oil enters the oil filling cylinder 4, the staff controls the electric push rod 6 to extend and drive the piston 61 to slide to the left. The piston 61 slides to the left. The initial oil in the oil filling cylinder 4 is discharged through the oil discharge pipe 31 for storage. When the electric push rod 6 is extended, it will also drive the touch handle 8 to move to the left. The touch handle 8 moves to the left and presses the electric valve 7, thereby opening the electric valve 7. At this time, the middle oil transported into the oil filling cylinder 4 by the oil connecting pipe 5 can flow into the filling container through the electric valve 7. After the sampling is completed, the staff controls the electric push rod 6 to shorten, thereby driving the piston 61 and the touch handle 8 to move to the right and reset, and the electric valve 7 is closed accordingly.

The threaded rod 9 is rotatably connected to the right upper side of the base 1. The nut 10 is threadedly connected to the threaded rod 9, and the nut 10 is fixedly connected to the mounting frame 2.

[0022] When using the device, the staff rotates the threaded rod 9, and the rotation of the threaded rod 9 can drive the nut 10 to move upward or downward. The up and down movement of the nut 10 drives the mounting frame 2 to slide up and down, and then adjusts the height of the connecting oil pipe 5, so that the oil connecting pipe 5 is flush with the oil outlet for easy docking.

[0023] like Figure 1 and Figure 3 As shown, the placement component includes a material receiving plate 11, an elastic member 12 and a limit block 13. The material receiving plate 11 is slidably connected to the middle of the base 1, the elastic member 12 is connected between the material receiving plate 11 and the base 1, and the upper side of the material receiving plate 11 is fixedly connected to a left-right symmetrical limit block 13.

[0024] When using the device, the staff controls the material receiving plate 11 to slide downward, and the elastic member 12 is deformed. After the material receiving plate 11 slides downward, the staff places the container on the material receiving plate 11 and limits the container by the limit block 13. After the container is placed, the staff releases the material receiving plate 11. Under the action of the elastic member 12 resetting, the material receiving plate 11 drives the container to move upward, thereby making the bottle mouth of the container dock with the electric valve 7, which is convenient for loading samples.
