Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, a kind of sand filter of oil production well of the utility model, including pump barrel 1, the flowline of top connection 2 and first
3, the top of barrel 1 is provided with top connection 2, and the side of top connection 2 is connected by flange with the first flowline 3, flowline 3 it is another
End is connected with the second flowline 5 and the 3rd flowline 9 respectively, and the middle part of the second flowline 5 is provided with the first valve 4, and second goes out
The other end of oil pipe 5 is connected with the side of the one end of the 3rd flowline 9, and the junction of the 3rd flowline 9 and the first flowline 3 is installed
There is the second valve 6, the middle part of the 3rd flowline 9 is connected with several U-tubes, and the inside of U-tube bottom is provided with filter core 8, the
The inwall of three flowlines 9 is provided with several grooves 13, and the oil-out 12 of the one end of the 3rd flowline 9 is provided with flowmeter 11.
Further, the internal welding in the middle part U-tube knee of the 3rd flowline 9 is connected to lonely shape projection 10, when crude oil flows through U
During shape pipe, lonely shape projection 10 can block the silt of some in crude oil, and then silt is deposited in U-shaped with Action of Gravity Field
