[0002] The porous nozzle for oil and gas well testing is a key tool for oil and gas well testing. It is usually installed in a fixed nozzle throttle valve to control the flow and pressure of the wellhead fluid for oil well testing and evaluation. This test uses a porous nozzle, which is made of YG8 material and has an inner core embedded in the nozzle outer sleeve. The nozzle inner core is arranged in the nozzle outer sleeve. The nozzle inner core is provided with multiple small-diameter inner core channels that are designed according to the critical throttling theory and are connected up and down.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-4The utility model provides a technical solution: a porous oil nozzle for oil and gas well testing, comprising a threaded head 1, a base 2 is fixedly connected to the surface of the threaded head 1, a nozzle port 3 is fixedly connected to the surface of the base 2, a plurality of holes 4 are opened on the inner wall of the nozzle port 3, a dust cover 5 is slidably connected to the surface of the base 2, two elastic ropes 6 are fixedly connected to the surface of the dust cover 5, one end of the two elastic ropes 6 away from the dust cover 5 is fixedly connected to a connecting plate 7, a cylinder 11 is fixedly connected to the surface of the connecting plate 7, the cylinder 11 is adapted to the inner wall of the nozzle port 3, and a porous plate 16 is installed on the inner wall of the base 2. By providing the dust cover 5, the elastic rope 6, the connecting plate 7 and the cylinder 11, the surface openings and threads of the threaded head 1 and the nozzle port 3 can be covered, so that dust and impurities will not enter the inside of the nozzle, and then when the oil pipe is connected to the porous oil nozzle for use, it will not affect the circulation of the internal liquid, which facilitates the use of the porous oil nozzle. The inner wall of the dust cover 5 is glued with a wiping block 8, which is made of sponge and fits the inner wall of the dust cover 5. When taking out the threaded head 1, the staff can rotate the threaded head 1, and the threaded head 1 contacts the wiping block 8 inside the dust cover 5. The wiping block 8 can scrape off the impurities on the threaded surface of the threaded head 1 or the grease produced by previous use, which can facilitate the docking of the threaded head 1 and the oil pipe. A guide frame 9 is fixedly connected to the surface of the dust cover 5, and the cross-section of the guide frame 9 is trapezoidal. Since the guide frame 9 is a structural design with a large outer surface and a small inner surface, it can play a guiding and auxiliary role when the threaded head 1 is docked and installed, which is used to facilitate the quick docking of the threaded head 1. A sealing ring 12 is glued to the surface of the cylinder 11, and the sealing ring 12 is made of rubber, and the cross-section of the sealing ring 12 is trapezoidal. The sealing ring 12 is designed to be small in the front and large in the back. When the cylinder 11 is inserted into the inner wall of the nozzle opening 3, it will not affect the insertion of the cylinder 11. Furthermore, the sealing ring 12 can improve the sealing effect of the cylinder 11 and prevent the entry of dust. The surface of the dust cover 5 is provided with a plurality of anti-skid grooves 10, and the plurality of anti-skid grooves 10 are linearly arrayed on the surface of the dust cover 5. When the porous nozzle needs to be installed on the surface of the oil pipe, the staff takes the protective cover. There are anti-skid grooves 10 on the surface of the protective cover. The anti-skid grooves 10 contact the staff's hands, which can increase the friction between the two, and thus facilitate the staff to take and carry the protective cover. The inner wall of the dust cover 5 is fixedly connected with six connecting rods 13, and the ends of the six connecting rods 13 away from the dust cover 5 are fixedly connected with sharp cones 14, and the wiping block 8 is slidably connected with the sharp cones 14 and the connecting rods 13. The inner wall of the dust cover 5 is connected with a connecting rod 13 and a pointed cone 14. Due to the addition of the connecting rod 13 and the pointed cone 14, the wiping block 8 will not be separated from the adhesive connection with the dust cover 5 when wiping the threaded head 1, thereby improving the service life of the adhesive connection of the wiping block 8. Six elastic sheets 15 are fixedly connected to the inner wall of the dust cover 5. The cross-sections of the six elastic sheets 15 are "V" and the six elastic sheets 15 are against the surface of the wiping block 8.When the thread head 1 is rotated and taken out, the elastic sheet 15 will drive the wiping block 8 to press against the thread surface of the thread head 1, thereby improving the wiping effect of the wiping block 8.
[0029] Working principle: After the porous oil nozzle is replaced, it will be cleaned and then placed in a fixed area so that it can be taken out for installation when needed. When placing the porous oil nozzle, the staff will first slide the threaded head 1 inside the dust cover 5. There is a guide frame 9 on the surface of the dust cover 5. Since the guide frame 9 is designed to be large on the outside and small on the inside, it can play a guiding and auxiliary role when the threaded head 1 is docked and installed, which is used to facilitate the rapid docking of the threaded head 1, and further slide the dust cover 5 to fit the surface of the base 2. The size of the dust cover 5 matches the size of the base 2 and can fit well. The staff will then pull the connecting plate 7, the cylinder 11 can be inserted into the inner wall of the nozzle port 3, and then the connecting plate 7 is loosened. At this time, the connecting plate 7 and the cylinder 11 will be affected by the elastic rope 6. The elastic rope 6 is tightened, so that the cylinder 11 can be stably inserted into the nozzle port 3. There is a sealing ring 12 on the surface of the cylinder 11. The sealing ring 12 is designed to be small in the front and large in the back. When the cylinder 11 is inserted into the inner wall of the nozzle port 3, it will not affect the insertion of the cylinder 11. Further, the sealing ring 12 can improve the sealing effect of the cylinder 11 and prevent the entry of dust. When the porous nozzle needs to be installed on the surface of the oil pipe, the staff takes the protective cover. There are anti-skid grooves 10 on the surface of the protective cover. The anti-skid grooves 10 and The contact of the staff's hands can increase the friction between the two, thereby making it easier for the staff to pick up and carry the protective cover. When performing the docking work, first pull the connecting plate 7 to disengage the cylinder 11 from the blocking seal of the oil nozzle port 3, and then the staff can take the threaded head 1 out of the dust cover 5. When taking out the threaded head 1, the staff can rotate the threaded head 1, and the threaded head 1 contacts the wiping block 8 inside the dust cover 5. The wiping block 8 can scrape off the dirt on the thread surface of the threaded head 1 or the grease generated by previous use, which can facilitate the docking work between the threaded head 1 and the oil pipe. At the same time, the inner wall of the dust cover 5 is connected with a connecting rod 13 and a pointed cone 1 4. Due to the addition of the connecting rod 13 and the pointed cone 14, the wiping block 8 will not be separated from the adhesive connection with the dust cover 5 when wiping the threaded head 1, thereby improving the service life of the adhesive connection of the wiping block 8. When the threaded head 1 is rotated and taken out, the elastic sheet 15 will drive the wiping block 8 to press against the threaded surface of the threaded head 1, thereby improving the wiping effect of the wiping block 8. A detachable porous plate 16 is provided inside the base 2. After long-term use, the porous plate 16 can be conveniently replaced without directly replacing the entire porous oil nozzle, thereby reducing material loss, improving the service life of the porous oil nozzle, and saving the cost of manufacturing the porous oil nozzle.
