Description

Technical Field

[0001] This utility model relates to the field of oil production equipment technology, specifically to a four-way structure for an oil production blowout preventer. Background Technology

[0002] Oil production engineering is a general term for various engineering and technical measures taken on the reservoir through production wells and injection wells during the oilfield development process according to the development goals. The existing blowout preventer four-way structure has a single function and simple structure. When the oil flows in the blowout preventer four-way structure, it is impossible to know the specific flow rate of the oil, which is inconvenient for the staff to adjust the valve.

[0003] Currently, existing technology (CN213869806U) discloses a four-way structure for a blowout preventer (BOP) in oil production equipment, including a BOP four-way structure body and a small ball head pin. A large flow meter and a small flow meter are sequentially installed from left to right on the outer front end of the BOP four-way structure body. Large mounting ports are fixed at the upper and lower ends of the outer side of the BOP four-way structure body, and large sealing rings are provided on the outside of the large mounting ports. A large T-sleeve is fixed inside the large mounting ports, and a large spring is installed on the outside of the large T-sleeve. A large ball head pin is provided on the outside of the large spring. Compared with existing ordinary BOP four-way structures, this technology can detect the oil flow rate in real time, change the flow rate of the BOP four-way structure through valves according to specific usage requirements, and precisely adjust the oil flow rate, thereby accurately controlling the oil flow rate of the BOP four-way structure. It has a wider range of applications.

[0004] However, using the above method, which involves inserting large-diameter and small-diameter ball head pins into the groove of the pipeline for fixation, can lead to vibrations during oil extraction due to the high pressure inside the pipeline. This can cause the ball head pins to slip out of the groove, affecting the normal use of the four-way structure. Utility Model Content

[0005] The purpose of this utility model is to provide a four-way structure for an oil blowout preventer, which aims to solve the problem that the existing four-way structure for blowout preventers used in oil production equipment uses large-diameter ball pins and small-diameter ball pins inserted into the groove of the pipeline for fixation. During the oil production process, the pressure inside the pipeline is high, which easily generates vibration, causing the ball pins to easily slide out of the groove of the pipeline, affecting the normal use of the four-way structure.

[0006] To achieve the above objectives, this utility model provides a four-way structure for an oilfield blowout preventer, including a four-way structure body and an installation assembly. The installation assembly includes a connector, a fixing cylinder, a sealing ring, a threaded head, a fastening ring, and an auxiliary unit.

[0007] The connector is fixedly connected to the four-way structure body and located on one side of the four-way structure body. The fixing cylinder is fixedly connected to the connector and located on the side of the connector. The sealing ring is fixedly connected to the fixing cylinder and located on the side of the fixing cylinder close to the connector. The threaded head is threadedly connected to the fixing cylinder and located on one side of the fixing cylinder. The fastening ring is slidably connected to the fixing cylinder and located on one side of the fixing cylinder. The auxiliary unit is disposed on one side of the four-way structure body.

[0008] The connector includes a large-diameter end and a small-diameter end. The large-diameter end is fixedly connected to the four-way structure body and is located on the top of the four-way structure body. The small-diameter end is fixedly connected to the four-way structure body and is located on the side of the four-way structure body.

[0009] The fixed cylinder includes a large-diameter cylinder and a small-diameter cylinder. The large-diameter cylinder is fixedly connected to the large-diameter end and is located on one side of the large-diameter end. The small-diameter cylinder is fixedly connected to the small-diameter end and is located on one side of the small-diameter cylinder.

[0010] The threaded head includes a large-diameter head and a small-diameter head. The large-diameter head is threadedly connected to the large-diameter cylinder and is located on one side of the large-diameter cylinder. The small-diameter head is threadedly connected to the small-diameter cylinder and is located on one side of the small-diameter cylinder.

[0011] The auxiliary unit includes a large-diameter flow meter and a small-diameter flow meter. The large-diameter flow meter is fixedly connected to the four-way structure body and is located on the side of the four-way structure body closer to the large-diameter end. The small-diameter flow meter is fixedly connected to the four-way structure body and is located on the side of the four-way structure body closer to the small-diameter end.

[0012] This utility model discloses a four-way structure for an oil blowout preventer (BOP). When installing the four-way structure on the BOP, first, the threaded head is fixed to the BOP and aligned with the fixed cylinder. Then, the connector is screwed clockwise into the fixed cylinder, pressing against the sealing ring. At this point, the fastening ring, installed on the outer wall of the fixed cylinder, provides radial fastening, allowing the BOP pipe on the connector to be more stably installed onto the four-way structure body, facilitating subsequent normal use. This solves the problem of existing four-way structures for BOPs in oil production equipment using large-diameter and small-diameter ball-head pins inserted into the pipe groove for fixation. During oil production, the high pressure inside the pipe easily causes vibration, making the ball-head pins slip out of the pipe groove, affecting the normal use of the four-way structure.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of a four-way structure for an oilfield blowout preventer according to this utility model.

[0021] This utility model discloses a four-way structure for an oil blowout preventer, comprising a four-way structure body 101 and an installation component 102. The installation component 102 includes a connector 103, a fixing cylinder 104, a sealing ring 105, a threaded head 106, a fastening ring 107, and an auxiliary unit 108. The connector 103 includes a large-diameter end 109 and a small-diameter end 110. The fixing cylinder 104 includes a large-diameter cylinder 111 and a small-diameter cylinder 112. The threaded head 106 includes a large-diameter head 113 and a small-diameter head 114. The auxiliary unit 108 includes a large-diameter flow meter 115 and a small-diameter flow meter 116. The aforementioned solution solves the problem that existing four-way structures for blowout preventers in oil production equipment use large-diameter and small-diameter ball pins inserted into the groove of the pipeline for fixation. During oil production, the pressure inside the pipeline is high, which easily generates vibration, causing the ball pins to easily slip out of the groove of the pipeline, affecting the normal use of the four-way structure.

[0022] In this specific embodiment, the blowout preventer pipeline is connected to the four-way structure body 101 to facilitate subsequent oil production operations.

[0023] The connector 103 is fixedly connected to the four-way structure body 101 and located on one side of the four-way structure body 101. The fixing cylinder 104 is fixedly connected to the connector 103 and located on the side of the connector 103. The sealing ring 105 is fixedly connected to the fixing cylinder 104 and located on the side of the fixing cylinder 104 near the connector 103. The threaded head 106 is threadedly connected to the fixing cylinder 104 and located on one side of the fixing cylinder 104. The fastening ring 107 is slidably connected to the fixing cylinder 104 and located on one side of the fixing cylinder 104. The auxiliary unit 108 is disposed on one side of the four-way structure body 101. When installing the four-way structure on the oil blowout preventer, the threaded head 106 is first fixed to the blowout preventer. The connector 103 is then screwed clockwise into the fixed cylinder 104, aligning the threaded head 106 with the fixed cylinder 104, so that it abuts against the sealing ring 105. At this time, the fastening ring 107 can be used. The fastening ring 107 is installed on the outer wall of the fixed cylinder 104 to provide radial fastening to the fixed cylinder 104, so that the blowout preventer pipe on the connector 103 can be more stably installed on the four-way structure body 101, which facilitates subsequent normal use. This solves the problem that the existing blowout preventer four-way structure for oil production equipment uses large-diameter ball head pins and small-diameter ball head pins to be fixed in the groove of the pipe. During the oil production process, the pressure inside the pipe is large and vibration is easy to occur, which makes the ball head pin easy to slip out of the groove of the pipe, affecting the normal use of the four-way structure.

[0024] Secondly, the large-diameter end 109 is fixedly connected to the four-way structure body 101 and located at the top of the four-way structure body 101, and the small-diameter end 110 is fixedly connected to the four-way structure body 101 and located on the side of the four-way structure body 101. The large-diameter end 109 is located at the upper and lower ends of the four-way structure body 101, and the small-diameter end 110 is located on the left and right sides of the four-way structure body 101, which can connect blowout preventer pipes in four directions.

[0025] Furthermore, the large-diameter cylinder 111 is fixedly connected to the large-diameter end 109 and located on one side of the large-diameter end 109, and the small-diameter cylinder 112 is fixedly connected to the small-diameter end 110 and located on one side of the small-diameter cylinder 112. The large-diameter cylinder 111 is located on the side of the large-diameter end 109, and the small-diameter cylinder 112 is located on one side of the small-diameter end 110, thereby enabling it to cooperate with the connector 103 to fix the position of the blowout preventer pipe.

[0026] In addition, the large-diameter head 113 is threadedly connected to the large-diameter cylinder 111 and is located on one side of the large-diameter cylinder 111. The small-diameter head 114 is threadedly connected to the small-diameter cylinder 112 and is located on one side of the small-diameter cylinder 112. The large-diameter head 113 is screwed clockwise into the large-diameter cylinder 111, and the small-diameter head 114 is screwed clockwise into the small-diameter cylinder 112. The blowout preventer pipe is then connected to the four-way structure body 101 and further secured with the fastening ring 107.

[0027] Meanwhile, the large-diameter flow meter 115 is fixedly connected to the four-way structure body 101 and located on the side of the four-way structure body 101 near the large-diameter end 109. The small-diameter flow meter 116 is fixedly connected to the four-way structure body 101 and located on the side of the small-diameter end 110 of the four-way structure body 101. In use, the large-diameter flow meter 115 can monitor the oil flow at the upper and lower ends of the four-way structure body 101, and the small-diameter flow meter 116 can monitor the oil flow on the left and right sides of the four-way structure body 101, which facilitates subsequent operations by the staff.

[0028] This utility model discloses a four-way structure for an oil blowout preventer. When installing the four-way structure on the oil blowout preventer, firstly, the threaded head 106 is fixed to the blowout preventer. The large-diameter head 113 is screwed clockwise into the large-diameter cylinder 111 on the large-diameter end 109, and the small-diameter head 114 is screwed clockwise into the small-diameter cylinder 112 on the small-diameter end 110. Then, the blowout preventer pipe is connected to the four-way structure body 101, so that the large-diameter head 113 and the small-diameter head 114 can abut against the sealing ring 105, and are further secured by the fastening ring 107. During use, the large-diameter flow meter 115 can monitor the oil flow at both ends of the four-way structure body 101, and the small-diameter flow meter 116 can monitor the oil flow on both sides of the four-way structure body 101, which facilitates subsequent operation by the staff. This solves the problem that existing blowout preventer four-way structures in oil production equipment use large-diameter ball pins and small-diameter ball pins to be fixed in the groove of the pipeline. During oil production, the pressure inside the pipeline is high and vibration is easy to occur, which makes the ball pin easy to slip out of the groove of the pipeline, affecting the normal use of the four-way structure.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
