Description

Technical Field

[0001] This utility model relates to the field of oil and gas field development technology, and in particular to an oil and gas wellhead baffle, an oil and gas well and a well site. Background Technology

[0002] Oil and gas wellheads are generally equipped with fixed grid plates for inspectors to easily observe the equipment downhole. When rainwater enters the well and causes the water level to rise, the equipment will float up due to the movement of a float. However, if the water volume is too large, the equipment will be blocked by the fixed grid plate as it floats up. As the water level continues to rise, the equipment will be submerged and damaged. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, which is that when there is water accumulation in the well and the water level is too high, the floating of the equipment in the well will be blocked by the fixed grid plate, and the equipment is easily submerged by the water accumulation, thus causing damage to the equipment. This invention provides an oil and gas wellhead baffle, an oil and gas well and a well site.

[0004] In a first aspect, the present invention provides an oil and gas wellhead baffle, comprising a grating plate, the grating plate comprising a fixed grating and a movable grating, the fixed grating being installed at the oil and gas wellhead, the fixed grating being hinged to the movable grating, and the movable grating being rotatable about the hinge point with the fixed grating.

[0005] The size of the grating plate is adapted to the oil and gas wellhead.

[0006] By installing a grating, inspection personnel can easily observe the equipment inside the well, improving the convenience of using the wellhead baffle. The fixed grating is hinged to the movable grating, allowing the movable grating to rotate around the hinge point. When the equipment inside the well rises and contacts the movable grating, it continues to rise with the rising water level, exerting a force on the movable grating and causing it to rotate around the hinge point. This design ensures that in cases of excessive water volume, the equipment can rise and push open the movable grating, exposing itself inside the well and reducing the likelihood of it being submerged and damaged by accumulated water.

[0007] The grating plate can be set to a circle or a rectangle according to actual needs, and is preferably set to a rectangle.

[0008] The hinge connection between the fixed grille and the movable grille can be configured such that one side of the fixed grille is hinged to one side of the movable grille, or the fixed grille is connected to the frame, and the movable grille is connected to the fixed grille through the frame.

[0009] This design improves the structural compactness of the wellhead baffle.

[0010] The oil and gas wellhead baffle also includes a frame, the fixed grid is connected to the frame, the movable grid is disposed in the frame, and the movable grid is hinged to the fixed grid through the frame.

[0011] The frame is provided with a limiting plate at its edge, which is used to restrict the downward rotation of the movable grille.

[0012] With this setting, when the movable grid is subjected to a downward force, the movable grid will not rotate, reducing the risk of objects or people falling into the well due to the rotation of the movable grid when they are moving above it, and improving the convenience of using the oil and gas wellhead baffle.

[0013] The fixed grid and the movable grid are connected by a hinge. A spring-back component is provided at the hinge between the fixed grid and the movable grid. The spring-back component is used to return the movable grid to its initial state.

[0014] The initial state refers to the state in which the movable grid rotates without being subjected to an upward force, and the surfaces of the movable grid and the fixed grid are on the same plane.

[0015] With this setting, when the equipment in the well no longer exerts force on the movable grid as the water level in the well decreases, the rebound component can bring the oil and gas wellhead baffle back to its initial state, improving the safety of using the oil and gas wellhead baffle.

[0016] The hinge can be configured as a hinge or hinge shaft, and the spring-loaded component can be configured as a spring or rubber pad.

[0017] Preferably, the hinge is a hinge shaft and the spring-loaded component is a spring.

[0018] The hinge shaft is coaxially arranged with the spring.

[0019] This setting allows for adjustment of the torque angle between the spring and the movable grille according to actual needs, achieving different elastic force application effects and thus improving the flexibility of the hinge.

[0020] In a second aspect, the present invention provides an oil and gas well, wherein the wellhead of the oil and gas well is provided with the aforementioned oil and gas wellhead baffle.

[0021] This setting reduces the likelihood of equipment inside oil and gas wells being damaged by water immersion, thereby reducing the maintenance costs of oil and gas wells.

[0022] In a third aspect, this utility model provides a well site using the aforementioned type of oil and gas well.

[0023] This setup improves the production efficiency of the well site.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This utility model provides an oil and gas wellhead baffle. With this setting, when encountering excessive water volume, the equipment inside the well can rise to the surface and push open the movable grid to be exposed from the well, reducing the probability of being submerged by the water inside the well and thus causing damage.

[0026] 2. This utility model provides an oil and gas well, wherein the wellhead of the oil and gas well is provided with the aforementioned oil and gas wellhead baffle. Through this setting, the probability of damage to the equipment inside the oil and gas well due to water immersion is reduced, thereby reducing the maintenance cost of the oil and gas well.

[0027] 3. This utility model provides a well site that uses the aforementioned oil and gas well, thereby improving the production efficiency of the well site. Attached Figure Description

[0039] Example 1

[0040] like Figures 1-3 As shown, this embodiment provides an oil and gas wellhead baffle, including a grid plate 1. The grid plate 1 includes a fixed grid 11 and a movable grid 12. The fixed grid 11 is used to be installed at the oil and gas wellhead. The fixed grid 11 is hinged to the movable grid 12. The movable grid 12 can rotate around the hinge point with the fixed grid 11.

[0041] By setting up the grating plate 1, it is possible for inspection personnel to easily observe the equipment inside the well, improving the convenience of using the wellhead baffle. By setting the fixed grating 11 and the movable grating 12 to be hinged, the movable grating 12 can rotate around the hinge point with the fixed grating 11. When the equipment inside the well floats up and comes into contact with the movable grating 12, the equipment inside the well continues to float up with the rise of the water level in the well, thereby applying a force to the movable grating 12, so that the movable grating 12 can rotate around the hinge point with the fixed grating 11 and move closer to the fixed grating 11, allowing the equipment inside the well to be exposed from the well. Through this setting, when encountering excessive water volume, the equipment inside the well can float up and push open the movable grating 12 to be exposed from the well, reducing the probability of being submerged by the water in the well and thus causing damage.

[0042] The grating plate 1 is rectangular.

[0043] The oil and gas wellhead baffle also includes a frame 13, the fixed grid 11 is connected to the frame 13, the movable grid 12 is disposed inside the frame 13, and the movable grid 12 is hinged to the fixed grid 11 through the frame 13.

[0044] This design improves the structural compactness of the wellhead baffle.

[0045] The frame 13 is provided with a limiting plate at its edge, which is used to restrict the downward rotation of the movable grille 12.

[0046] With this setting, when the movable grid 12 is subjected to a downward force, the movable grid 12 will not rotate, reducing the risk of objects or people falling into the well due to the rotation of the movable grid 12 when they are moving above it, and improving the convenience of using the oil and gas wellhead baffle.

[0047] The fixed grid 11 and the movable grid 12 are connected by a hinge. A spring-back component is provided at the hinge between the fixed grid 11 and the movable grid 12. The spring-back component is used to return the movable grid 12 to its initial state.

[0048] The initial state refers to the state in which the movable grille 12 rotates without being subjected to an upward force, and the surface of the movable grille 12 is on the same plane as the surface of the fixed grille 11.

[0049] With this setting, when the equipment in the well no longer exerts force on the movable grid 12 as the water level in the well decreases, the rebound component can bring the oil and gas wellhead baffle back to its initial state, improving the safety of using the oil and gas wellhead baffle.

[0050] The hinge can be configured as a hinge or hinge shaft 2, etc., and the spring-back component can be configured as a spring 3 or a rubber pad, etc.

[0051] Preferably, the hinge is a hinge shaft 2 and the spring-loaded component is a spring 3.

[0052] The hinge shaft 2 is coaxially arranged with the spring 3.

[0053] This setting allows for adjustment of the torque angle between spring 3 and movable grille 12 according to actual needs, achieving different elastic force application effects and thus improving the flexibility of the hinge.

[0054] Example 2

[0055] This embodiment provides an oil and gas well, wherein the wellhead of the oil and gas well is provided with the aforementioned oil and gas wellhead baffle.

[0059] This setup improves the production efficiency of the well site.
