Problems solved by technology

The original method is for the well team to process the steel mud shield by themselves. Because the overall weight is large, and it is under the drill floor, the space is small and high from the ground, which is inconvenient for hoisting and safety cannot be guaranteed; some well teams directly use plastic cloth. Wrapping the well sealer, unable to check the equipment normally

Embodiment 1

[0028] The embodiment of the present invention provides a device for quickly fixing and disassembling the mud umbrella, which is installed between the overflow prevention pipe 1 and the well sealing device or the casing head assembly 3, and the well sealing device or the casing head assembly 3 is fixed to the ground 2 Above, the device is used to prevent the pollution of the blowout preventer by the mud falling from the spill pipe 1 and the upper drilling floor surface.

[0029] Such as figure 1 and figure 2 As shown, the device for quickly fixing and disassembling the mud umbrella includes a support plate 4, an umbrella frame fixed on the support plate 4, the umbrella frame is worn on the mud umbrella 5, and the center of the mud umbrella 5 is fixed on the support Plate 4 on.

[0030] The umbrella frame is formed by connecting a plurality of support rods 6 through short joints; the support rods 6 include top support rods and side support rods, and a plurality of top suppor...

Embodiment 2

[0035] Such as image 3 As shown, the mud umbrella 5 includes the mud umbrella main body 9, and the umbrella cloth fixing strip 8 connected to the mud umbrella main body 9, and the umbrella cloth fixing strip 8 and the mud umbrella main body 9 are provided with for the support rod 6 to wear. Set the gap to 10.

[0036] The present invention is provided with umbrella cloth fixing strip 8 on the mud umbrella main body 9, can facilitate support bar 6 to be installed on the mud umbrella main body 9 quickly like this, saves the fixing and dismounting time of mud umbrella 5.

Embodiment 3

[0038] On the basis of Embodiment 2, the umbrella cloth fixing strip 8 and the main body of the mud umbrella 5 are all processed by waterproof and oil-proof flexible materials, and the umbrella cloth fixing strip 8 is fixed on the mud umbrella main body 9 through reinforcement means such as sewing . Wherein, the flexible material can be plastic, tarpaulin and so on.

[0039] The umbrella cloth fixing strip 8 of the present invention is made of the same material as the mud umbrella main body 9, which facilitates its processing onto the mud umbrella main body 9; and the same material is used to facilitate the purchase of raw materials. Of course, different materials can also be selected according to actual conditions.

Abstract

The invention relates to the field of drilling engineering machinery, in particular to a device and a method for fixing, mounting and dismounting a mud guard umbrella rapidly. The device is mounted between an anti-overflow pipe and a well plugging device or a casing head component and comprises a supporting disk and an umbrella framework fixed on the supporting disk. The umbrella framework is arranged on the mud guard umbrella penetratingly and is formed by sleeving connection of a plurality of supporting rods through connecting pup joints, the center of the mud guard umbrella is fixed on the supporting disk, the supporting rods include top face supporting rods and side face supporting rods, a plurality of top face supporting rods are connected end to end through the connecting pup joints to form a top face frame, the upper ends of the side face supporting rods are connected with the top face frame, and the lower ends thereof are fixed on the supporting disk. The method includes the steps of opening the mud guard umbrella by the umbrella framework and the supporting disk and dismounting the umbrella framework and the supporting disk. The method and the device have the advantages of simplicity in fixing, mounting and dismounting principles, simplicity and convenience in operation, rapidity, safety, low labor intensity, high mounting and dismounting efficiency, convenience in carrying and no effect on use of original equipment.

Description

technical field [0001] The invention relates to the field of drilling engineering machinery, in particular to a device for quickly fixing and disassembling a mud umbrella and a method for fixing and disassembling it. Background technique [0002] Installing mud shields is an important job for the drilling team. The well team equipped with the well sealing device must install a mud shield on it to prevent the pollution of the blowout preventer by the mud falling from the overflow pipe and the upper drilling floor surface, so as to ensure that the blowout preventer can be checked, controlled and available at any time. The original method is for the well team to process the steel mud shield by themselves. Because the overall weight is large, and it is under the drill floor, the space is small and high from the ground, which is inconvenient for hoisting and safety cannot be guaranteed; some well teams directly use plastic cloth. Wrapping the well sealer, unable to check the equ...
