Description

Technical Field

[0001] This utility model relates to the field of oil extraction equipment technology, specifically to a sand control and throttling manifold device. Background Technology

[0002] Choke and kill manifolds are essential equipment for controlling well kicks and implementing oil and gas well pressure control technology. With the water jet closed, the choke valve is used to control a certain pressure, ensuring that the bottom hole pressure is always slightly higher than the formation pressure, thus preventing formation fluids from flowing further into the well. In addition, during well shut-in, the choke and kill manifold can achieve soft shut-in by releasing pressure through the choke pipe. When the pressure inside the well rises to a certain limit, it will be ejected to protect the wellhead.

[0003] The existing throttling manifold devices have the following drawbacks during use: oil and gas extraction processes usually contain impurities such as mud, sand, and water. Under enormous pressure, the impact of the sand can often damage the manifold device. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a sand-prevention and throttling manifold device, comprising: a manifold body, a filter mechanism and a discharge mechanism. The filter mechanism is installed on one side of the manifold body and includes an outlet pipe fixed on one side of the manifold body, a housing fixed at the end of the outlet pipe, an inlet pipe installed on the other side of the housing, an annular protrusion fixed on the inner wall of the housing, a filter element disposed above the annular protrusion, and a locking element installed on the top of the housing and passing through the filter element by a threaded connection.

[0006] The discharge mechanism includes a cylinder fixed to the bottom of the shell and communicating with the inner cavity of the shell, a movable component movably disposed in the inner cavity of the cylinder, an electric telescopic rod installed on one side of the cylinder and fixedly connected to the end of the movable component, and sand discharge pipes symmetrically disposed on both sides of the cylinder.

[0007] In a preferred embodiment, the present invention can be further configured such that the filter element includes an annular frame disposed above the annular protrusion and a filter screen fixed on the inner wall of the annular frame, wherein the annular frame has insertion holes arranged in a circular array.

[0008] In a preferred embodiment, the present invention can be further configured such that the locking member includes a sealing plug installed on the top of the housing via a threaded connection and a locking rod fixed in a ring array at the bottom end of the sealing plug, the bottom end of the locking rod being fitted into the insertion hole.

[0009] In a preferred embodiment, the present invention can be further configured such that the movable component includes three pistons movably disposed within the inner cavity of the cylinder and two connecting rods connecting adjacent pistons.

[0010] In a preferred embodiment, the present invention can be further configured such that: three pistons form two sand storage cavities in the inner cavity of the cylinder, and when one sand storage cavity is located in the middle of the inner cavity of the cylinder, the sand storage cavity is connected to the inner cavity of the shell, and the sand storage cavity on the other side is connected to the sand discharge pipe.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] 1. In this utility model, a filter mechanism is installed on the manifold body. The filter mechanism consists of an outlet pipe, an inlet pipe, an annular protrusion, a filter element, and a locking element. After the fluid medium enters the housing through the inlet pipe, the sand and gravel it contains can be filtered out by the filter element. The sand and gravel can fall into the bottom of the housing under their own gravity and enter the discharge mechanism for discharge. This effectively prevents the sand and gravel from impacting and damaging the manifold device, thus increasing its performance. In addition, the filter element is installed in the inner cavity of the housing through the locking element. When the filter element is damaged, the locking element can be unscrewed to replace the filter element, further increasing the convenience of use.

[0013] 2. In this utility model, a discharge mechanism is installed at the bottom of the shell and connected to the shell. The discharge mechanism consists of a cylinder, a movable part, an electric telescopic rod, and a sand discharge pipe. The sand and gravel filtered out in the shell falls into the cylinder along the shell and enters the cavity of the movable part. At this time, the electric telescopic rod drives the movable part to move, so that the cavity of the movable part is aligned with the sand discharge pipe, and the sand and gravel in the cavity can be discharged outward from the sand discharge pipe. This cycle can prevent sand and gravel from accumulating in the inner cavity of the shell and further improve the practical performance. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figure 1-5 As shown, this embodiment provides a sand-prevention and throttling manifold device, including: a manifold body 100, a filter mechanism 200, and a discharge mechanism 300.

[0027] The filter mechanism 200 is installed on one side of the manifold body 100 and is used to filter sand and gravel in the fluid medium. It includes an outlet pipe 210 fixed on one side of the manifold body 100, a housing 220 fixed at the end of the outlet pipe 210, an inlet pipe 230 installed on the other side of the housing 220, an annular protrusion 240 fixed on the inner wall of the housing 220, a filter element 250 disposed above the annular protrusion 240, and a locking member 260 installed on the top of the housing 220 and passing through the filter element 250 by a threaded connection.

[0028] The inlet pipe 230 is used to input the fluid medium into the inner cavity of the housing 220, the outlet pipe 210 is used to send out the filtered fluid medium, the housing 220 is used to install other components, the annular protrusion 240 is used to install the filter element 250, in addition, the outlet pipe 210 is located above the inlet pipe 230, and the filter element 250 is located between the inlet pipe 230 and the outlet pipe 210, so as to facilitate the fluid medium to pass through the filter element 250.

[0029] The filter element 250 includes an annular frame 251 disposed above the annular protrusion 240 and a filter screen 252 fixed on the inner wall of the annular frame 251. The annular frame 251 is used to install the filter screen 252 and ensure the stability of the filter screen 252. The filter screen 252 is used to filter sand and gravel in the fluid medium.

[0030] The locking member 260 is used to lock the filter element 250. It includes a sealing plug 261 that is threadedly installed on the top of the housing 220 and a locking rod 262 that is fixed in a ring array at the bottom of the sealing plug 261. The sealing plug 261 can seal the top of the housing 220 and is used to install the locking rod 262. The ring frame 251 has a ring array of insertion holes 2511. The bottom of the locking rod 262 is fitted into the insertion holes 2511, which can ensure the stability of the ring frame 251 and prevent the filter element 250 from being affected by the impact of the fluid medium.

[0031] The discharge mechanism 300 is used to discharge the filtered sand and gravel to prevent them from accumulating in the inner cavity of the housing 220. It includes a cylinder 310 fixed to the bottom of the housing 220 and communicating with the inner cavity of the housing 220, a movable part 320 movably disposed in the inner cavity of the cylinder 310, an electric telescopic rod 330 installed on one side of the cylinder 310 and fixedly connected to the end of the movable part 320, and sand discharge pipes 340 symmetrically disposed on both sides of the cylinder 310.

[0032] The middle part of the cylinder 310 is connected to the shell 220. The movable part 320 includes three pistons movably disposed in the inner cavity of the cylinder 310 and two connecting rods 322 connecting adjacent pistons 321. Through this arrangement, the three pistons 321 form two sand storage cavities in the inner cavity of the cylinder 310. When one sand storage cavity is located in the middle of the inner cavity of the cylinder 310, the sand storage cavity is connected to the inner cavity of the shell 220, so that the sand and gravel filtered out of the inner cavity of the shell 220 can fall into the sand storage cavity. The other sand storage cavity is connected to the sand discharge pipe 340, so that the sand and gravel in the sand storage cavity can be discharged through the sand discharge pipe 340. The electric telescopic rod 330 is used to drive the movable part 320 to reciprocate. Through the reciprocating movement of the movable part 320, the two sand storage cavities are aligned with the sand discharge pipe 340 to ensure the discharge of sand and gravel.

[0033] The working principle and usage process of this utility model are as follows: During use, the fluid medium enters the inner cavity of the shell 220 through the inlet pipe 230 and then flows upwards from the shell 220. At this time, the filter screen 252 filters the sand and gravel in the fluid medium. The filtered fluid medium is sent out through the outlet pipe 210. At the same time, the filtered sand and gravel fall down along the shell 220 under its own gravity and enter the inner cavity of the cylinder 310. After entering the inner cavity of the cylinder 310, the sand and gravel fall into the sand storage cavity formed by the adjacent piston 321 and the inner wall of the cylinder 310. Then, the electric telescopic rod 330 is activated, which drives the movable part 320 to move, so that the sand storage cavity is aligned with the sand discharge pipe 340 on one side. At this time, the sand and gravel in the sand storage cavity can be discharged outwards through the sand discharge pipe 340. Then, the above process can be repeated.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
