Description

Technical Field

[0001] This utility model relates to the technical field of throttling manifolds, specifically a throttling manifold with a filtration and slag discharge mechanism. Background Technology

[0002] A choke manifold is a common flow control element, composed of multiple choke tubes, and possesses precise flow control capabilities. Its simple structure and mature manufacturing process have led to its widespread application in petroleum, chemical, metallurgical, and pharmaceutical industries. The choke manifold is essential equipment for controlling well kicks and implementing oil and gas well pressure control technology. With the blowout preventer (BOP) closed, the opening and closing of the choke valve controls a certain casing pressure to maintain the bottom hole pressure slightly higher than the formation pressure, preventing formation fluids from further flowing into the well. Furthermore, during well shut-in, the choke manifold can be used to release pressure for a soft shut-in.

[0003] After searching, it was found that a typical example of a throttling manifold in the prior art is disclosed in CN217327268U, which includes a mounting frame, a pipe fitting assembly, and a valve. The lower end of the pipe fitting assembly is connected to the mounting frame via a vertical rod. Two supports are symmetrically placed on both sides of the pipe fitting assembly and are fixedly connected to the upper end of the mounting frame. Two horizontally placed support plates are erected between the two supports. The two support plates are connected to adjusting bolts located in the supports. The two support plates are symmetrically arranged below the pipe fitting assembly. Multiple longitudinally arranged support blocks are laid on the upper part of the two support plates.

[0004] In summary, existing choke manifolds, when in use, typically contain sediment in the oil and gas extracted from wells, which causes significant damage to oil and gas extraction equipment. Friction and impact quickly damage the equipment, necessitating replacement, increasing extraction costs, delaying extraction time, and reducing work efficiency. Secondly, existing choke manifolds are generally integral structures without lifting functions, making it inconvenient to connect with other pipelines during installation due to insufficient length, causing installation difficulties. To address these issues, improvements to the existing equipment are necessary. Utility Model Content

[0005] The purpose of this utility model is to provide a throttling manifold with a filtration and slag removal mechanism to solve the problems mentioned in the background art. Existing throttling manifolds, when used, typically produce oil and gas from wells containing a certain amount of silt, which causes significant damage to oil and gas production equipment. Friction and impact quickly damage the equipment, necessitating replacement, increasing extraction costs, delaying extraction time, and reducing work efficiency. Furthermore, existing throttling manifolds are generally integral structures without lifting functions, leading to inconvenience during installation due to insufficient length when connecting with other pipelines, causing installation difficulties.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a throttling manifold with a filtration and slag discharge mechanism, comprising a first throttling manifold.

[0007] One end of the first throttling manifold is connected to one end of the connecting sleeve via a filtration and slag discharge mechanism. The filtration and slag discharge mechanism includes a collection box. A threaded sleeve is provided in the middle of one side of the collection box, and a slag discharge pipe is provided on the outer side of the slag discharge port opened in the middle of the lower end of the collection box. A slag discharge valve is installed on the slag discharge pipe. The other end of the collection box is connected to the filter box, and the two sides inside the filter box are connected to the filter assembly via a locking limit seat. The top of the filter assembly passes through the sealing cover and extends above the sealing cover. The second throttling manifold is connected to the other side of the connecting sleeve via a threaded ring seat, and a sealing reinforcement component is provided on the outer side of the connection between the connecting sleeve and the second throttling manifold.

[0008] Preferably, the first throttling manifold, the collection box, the connecting sleeve, and the inner side of the second throttling manifold are all coated with a wear-resistant and rust-proof coating.

[0009] Preferably, the filter assembly includes a first filter plate, a second filter plate, a third filter plate, and a fourth filter plate, and the first filter plate, the second filter plate, the third filter plate, and the fourth filter plate are arranged sequentially from left to right.

[0010] Preferably, the filter holes on the first and fourth filter plates have the same diameter, and the filter holes on the first and fourth filter plates have a smaller diameter than the filter holes on the second and third filter plates, and the filter holes on the second filter plate have a smaller diameter than the filter holes on the third filter plate.

[0011] Preferably, the bottom of the sealing cover is connected to the top of the filter box via a sealing ring, and the top of the sealing cover is threaded to the filter box via multiple fixing screws passing through the sealing cover and the sealing ring. At the same time, a rubber sleeve is provided at the connection between the sealing cover and the filter assembly.

[0012] Preferably, the sealing reinforcement assembly includes a sealing sleeve, extension rods, and a positioning ring seat. The inner side of the sealing sleeve is threadedly connected to the outer side of the connecting sleeve away from the filter box, and a sealing gasket is provided between the inner side of the sealing sleeve and the end face of the connecting sleeve. At the same time, multiple extension rods are equidistantly arranged on the outer side of the sealing sleeve, and the other end of the extension rods is connected to the positioning ring seat. The positioning ring seat is sleeved on the outer side of the second throttling manifold, and the positioning ring seat and the second throttling manifold are detachably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the throttling manifold with a filter and slag discharge mechanism,

[0014] (1) In order to solve the problem that the oil and gas extracted from the well usually contains a certain amount of mud and sand when the existing throttling manifold is used, which is very damaging to the oil and gas extraction equipment, the equipment will be damaged quickly due to friction and impact, so it needs to be replaced, which increases the extraction cost, delays the extraction time, and reduces the work efficiency. This application sets up a collection box, a filter box and a filter assembly for use together, so that the filter assembly filters the sand and gravel. The filtered sand and gravel is discharged through the slag discharge port opened in the collection box. At the same time, the filter hole diameters set on the filter assembly are different, which can improve the filtration effect without reducing the liquid flow rate. By pulling the filter assembly, it is easy to clean the filter screen, which improves the service life and the use effect.

[0015] (2) In order to solve the problem that the existing throttling manifolds are generally integral structures without lifting function, which makes it inconvenient to connect with other pipes during installation and causes trouble due to insufficient length, this application uses a threaded ring seat to make the second throttling manifold and the connecting sleeve threadedly engaged. When it is necessary to adjust the length of the second throttling manifold, the second throttling manifold is rotated, which causes the threaded ring seat to move inside the connecting sleeve, thereby adjusting the length of the second throttling manifold. Under the action of the sealing and reinforcement component, the sealing and stability of the connection between the second throttling manifold and the connecting sleeve are improved.

A slag discharge pipe 4 is provided on the outer side of the lower end of the slag discharge port 301 opened in the middle of the lower end of the collection box 3 to facilitate the discharge of filtered sand and gravel. At the same time, a slag discharge valve 5 is installed on the slag discharge pipe 4. The other end of the collection box 3 is connected to the filter box 6. The two sides inside the filter box 6 are connected to the filter assembly 7 through the provided locking limit seats 601. At the same time, the top of the filter assembly 7 passes through the sealing cover 8 and extends above the sealing cover 8. The filter assembly 7 includes a first filter screen 701, a second filter screen 702, a third filter screen 703, and a fourth filter screen 704. The first filter screen 701, the second filter screen 702, the third filter screen 703, and the fourth filter screen 704 are also connected. 02. The third filter plate 703 and the fourth filter plate 704 are arranged sequentially from left to right. The filter holes on the first filter plate 701 and the fourth filter plate 704 have the same diameter, and the filter holes on the first filter plate 701 and the fourth filter plate 704 have a smaller diameter than the filter holes on the second filter plate 702 and the third filter plate 703. The filter holes on the second filter plate 702 have a smaller diameter than the filter holes on the third filter plate 703, which facilitates the filtration of sand and gravel in the liquid. The bottom of the sealing cover 8 is connected to the top of the filter box 6 through a sealing ring, and the top of the sealing cover 8 is threaded to the filter box 6 through multiple fixing screws. At the same time, a rubber sleeve is provided at the connection between the sealing cover 8 and the filter assembly 7 to improve the sealing performance.

[0023] according to Figure 1 , Figure 2 and Figure 3As shown, the second throttling manifold 14 is connected to the other side of the connecting sleeve 9 via a threaded ring seat 15. A sealing reinforcement assembly is provided on the outside of the connection between the connecting sleeve 9 and the second throttling manifold 14. The sealing reinforcement assembly includes a sealing sleeve 11, an extension rod 12, and a positioning ring seat 13. The inner side of the sealing sleeve 11 is threadedly connected to the outer side of the connecting sleeve 9 away from the filter box 6. A sealing gasket 10 is provided between the inner side of the sealing sleeve 11 and the end face of the connecting sleeve 9.

The filtered sand and gravel accumulate in the collection tank 3. When it is necessary to clean the sand and gravel, the slag discharge valve 5 is opened, and the sand and gravel collected in the collection tank 3 are discharged into the slag discharge pipe 4 through the slag discharge port 301. When it is necessary to clean the sand and gravel stuck on the filter assembly 7, the filter assembly 7 is pulled out from inside the filter tank 6 for cleaning. The cleaned liquid is then connected to... The sleeve 9 and the second throttling manifold 14 discharge liquid. When the length of the second throttling manifold 14 needs to be adjusted, the second throttling manifold 14 is rotated so that the threaded ring seat 15 rotates inside the connecting sleeve 9, and the second throttling manifold 14 is pulled out from inside the connecting sleeve 9 by a certain length to facilitate connection with the equipment. Then, with the combined use of the sealing gasket 10, sealing sleeve 11, extension rod 12 and positioning ring seat 13, liquid leakage from the connection between the second throttling manifold 14 and the connecting sleeve 9 is effectively prevented, and the sealing performance is improved.
