Description

Technical Field

[0001] This utility model relates to the field of oil sample collection technology, and more specifically, to an oil well analysis oil sample extractor. Background Technology

[0002] In the process of oilfield production, in order to grasp the production dynamics of oil wells and changes in oil layers, it is essential to conduct chemical analysis of crude oil. When conducting full analysis, it is required that the oil samples taken by the oil production workers are free of water. However, after the oilfield development enters the high water-cut period.

[0003] To maintain and stabilize production, the number of wells undergoing perforation and formation modification is constantly increasing, leading to a corresponding increase in the frequency of crude oil sampling and analysis. This also increases the workload and difficulty of oil sampling. As oilfield development enters a high water-cut phase, with most wells containing over 90% water, obtaining sufficient qualified crude oil requires thorough oil-water separation, often through repeated operations. This increases the labor intensity for oilfield workers while reducing sampling efficiency. Therefore, a suitable oil well analysis sample extractor is needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an oil well analysis oil sample extractor, which facilitates rapid sampling of oil samples through sampling components and separation components, thereby improving the ease of use of the device.

[0007] The sampling assembly includes a pull plate, a limiting top plate at the bottom of the pull plate, a sealing plug at the bottom of the limiting top plate, a sampling rod at the bottom of the sealing plug, and a sampling cup at the bottom of the sampling rod.

[0008] Furthermore, the top of the mounting frame is connected to the bottom of the separation tank by bolts, and a drive motor is mounted in the middle of the bottom of the mounting frame by bolts. The output end of the drive motor is connected to a drive pulley, and the drive pulley is arranged adjacent to the mounting frame. The mounting frame provides positioning support for the drive motor, and the drive motor drives the drive pulley.

[0009] Furthermore, a connecting belt is fitted on the middle outer wall of the driving pulley, and a driven pulley is fitted on the end of the connecting belt away from the driving pulley. A supporting screw rod is snapped into the middle of the driven pulley, and the supporting screw rod is connected to the middle of the bottom of the separation tank through a bearing.

[0015] 2. The oil inside the oil-water separator is sampled by the sampling rod and sampling cup. By pulling the pull plate and the limiting top plate, the sealing plug is separated from the top plate, thereby causing the sampling rod to lift the sampling cup, and the oil sample is taken during the lifting process.

The supporting screw rod 10 is connected to the bottom center of the separation tank 1 via a bearing, and the top of the supporting screw rod 10 is connected to the top plate 14 via a bearing. An oil-water separation frame 11 is fitted on the outer wall of the supporting screw rod 10, and the oil-water separation frame 11 is threadedly connected to the supporting screw rod 10. A limiting groove 12 is opened on the outer wall of the oil-water separation frame 11, and there are three limiting grooves 12, which are evenly distributed on the outer wall of the oil-water separation frame 11. A limiting slide rail 13 is slidably connected in the middle of the limiting groove 12, and the side of the limiting slide rail 13 away from the limiting groove 12 is fixedly connected to the inner wall of the separation tank 1.

[0027] It should be noted that this utility model is an oil well analysis oil sample extractor. In use, the feed pipe 2 is connected to the equipment's oil delivery pipe, allowing oil and water to be introduced into the separator 1. The oil and water enter the oil-water separator 11. A drive motor 6 drives the active pulley 7 to rotate, which in turn drives the connecting belt 9 and the driven pulley 8 to rotate. The connecting belt 9 is fitted over the active pulley 7 and the driven pulley 8. The driven pulley 8 then drives the supporting screw rod 10 to rotate, causing the oil-water separator 11 to move upwards along the outer wall of the supporting screw rod 10. During the movement, water inside the oil-water separation frame 11 enters the separation tank 1 through the bottom of the oil-water separation frame 11, while oil remains inside the oil-water separation frame 11, thus achieving the separation of water and oil. When the top of the oil-water separation frame 11 contacts the bottom of the top plate 14, the bottom of the oil-water separation frame 11 pushes out the sampling cup 20 and the sampling rod 19, causing the sampling rod 19 to drive the sealing plug 18 to separate from the top plate 14. Pulling the pulling plate 16 causes the pulling plate 16 to drive the sampling rod 19 and the sampling cup 20 to be taken out from the sampling groove at the top of the top plate 14, completing the sampling of the oil sample.
