[0002] The Christmas tree is the main equipment for controlling and regulating oil and gas production at the top of the oil and gas well. It mainly consists of three parts: casing head, tubing head and Christmas (gas) tree body. The Christmas tree is one of the very important equipment in oil and gas production. It can realize the control, regulation and measurement of oil and gas to ensure the smooth progress of oil and gas production. At the same time, the Christmas tree can also provide conditions for daily production management and provide necessary data support and maintenance guarantee for oil and gas production.

[0003] Currently, the oil pipe used in the Christmas tree is a single pipe. When the pipe is damaged, it is often necessary to suspend oil transportation and then shut down the entire pipe before the pipe can be dismantled for repair. In addition, the oil transportation volume can only be controlled and managed by controlling the flow rate of the single pipe during oil transportation, which makes the oil transportation efficiency low and also increases the oil transportation cost.

[0023] Specifically, a supporting plate 11 is fixed between the two supporting frames 10, and three transmission pipes 6 are connected to the bottom end of the outer side of each filter oil pipe 3. Three fixed grooves 14 are fixed on one side of the filter oil pipe 3 that fits the transmission pipe 6. A filter net 15 is fixed in each fixed groove 14, so that impurities inside the filter oil pipe 3 are filtered by the filter net 15.

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, each transmission pipe 6 is provided with a second valve 7, the bottom end of the transmission pipe 6 is fixedly connected to the recovery box top cover 8, the transmission pipe 6 passes through the inside of the recovery box top cover 8, the inside of the recovery box top cover 8 is slidably connected to the recovery box body 9, and the recovery box body 9 is slidably connected to the top surface of the supporting plate 11, so that impurities are discharged into the inside of the recovery box body 9 through the transmission pipe 6.

[0025] Specifically, the filtering density of the filter 15 near the oil outlet pipe 2 inside the filter pipe 3 is smaller than the filtering density of the filter 15 in the middle of the filter pipe 3, and the filtering density of the filter 15 in the middle of the filter pipe 3 is smaller than the filtering density of the filter 15 near the oil collecting pipe 4 inside the filter pipe 3, so that the filter 15 filters the impurities inside the filter pipe 3 in turn, and sealing sliders 12 are fixed on both sides above the recovery box main body 9, and sealing grooves 13 matching the shape of the sealing sliders 12 are opened on both sides inside the recovery box top cover 8, and sealing rubber is arranged inside the sealing groove 13, so that the recovery box main body 9 is better airtight, and a buckle is rotatably connected on one end of the recovery box top cover 8, and a lock buckle matching the buckle is fixed on one end of the recovery box main body 9, so that the recovery box top cover 8 fixes the recovery box main body 9.

[0026] Working principle: oil is input into the oil outlet pipe 2 from the main body 1 of the oil tree, and the oil outlet pipe 2 then divides the oil into two filter oil pipes 3. The oil passing through the two filter oil pipes 3 is discharged through the oil collecting pipe 4. When one filter oil pipe 3 is damaged, the first valve 5 on the oil outlet pipe 2 close to the damaged filter oil pipe 3 is closed, so that the oil inside the filter oil pipe 3 is discharged, and then the first valve 5 on the oil collecting pipe 4 close to the damaged filter oil pipe 3 is closed, so that the inside of the filter oil pipe 3 cannot circulate. At this time, the staff can dismantle the filter oil pipe 3 for maintenance and replacement. When the impurities inside the filter oil pipe 3 need to be cleaned, the first valves 5 at both ends of the corresponding filter oil pipe 3 are repeatedly closed, and then the second valve 7 on the transmission pipe 6 is opened, so that the impurities inside the filter oil pipe 3 are discharged from the transmission pipe 6 to the inside of the recovery box main body 9. After the discharge is completed, the second valve 7 is closed again, and then the first valves 5 at both ends of the filter oil pipe 3 are opened to circulate inside the filter oil pipe 3. At the same time, the buckle limit between the recovery box main body 9 and the recovery box top cover 8 is released, and the recovery box main body 9 can be drawn out from the inside of the recovery box top cover 8 for cleaning.
