Description

Technical Field

[0001] The utility model relates to the technical field of wellhead control panels, in particular to a modular wellhead control panel assembly box. Background Art

[0002] In the existing technology, the wellhead control panel is an important safety control device in the oil field to ensure the opening and closing of the Christmas tree safety valve. When an oil and gas well fails, it can quickly shut down the well, fully protecting the safety of personnel and property in the oil and gas field. The wellhead control panel commonly seen in existing oil and gas fields is an integral structure. The internal pipelines and accessories of the wellhead control panel are installed tightly and the space is small. The equipment is under long-term high-pressure conditions and expands and contracts for a long time. The joints and valves will be affected to a certain extent, resulting in slight leakage of some joints and accessories. The joints and accessories may even leak due to vibration of the oil and gas field. Many inconveniences will occur when repairing and replacing joints and accessories. It may even be necessary to remove many joints, pipelines and accessories that have not caused problems to repair and replace failed accessories, thereby reducing work efficiency. In addition, the shell structure of the existing wellhead control panel is too simple and the distribution is unreasonable. The junction box is mostly designed at the top of the shell or at the bottom of the wellhead control panel. The design of the top junction box will cause rainwater to penetrate into the interior under long-term seawater corrosion, causing electrical equipment failure. The design of the internal junction box will soak the internal accessories in the event of oil leakage. Long-term immersion will cause hydraulic oil to penetrate into the junction box, which will also cause electrical equipment failure.

[0003] The Chinese utility model patent application number: 201820643562.1 discloses a new modular multi-well wellhead control panel, including a control panel housing, in which a main controller, several single-well modules, an oil tank, a booster pump and an accumulator are arranged. An accumulator buffer seat is provided under the accumulator, and an elastic rubber pad is provided between the accumulator buffer seat and the bottom of the accumulator. The accumulator is covered with a clamp, and a vertical fixing plate is provided on one side of the clamp and fixed to the inner wall of the control panel housing through the fixing plate. Several buffer springs are provided between the fixing plate and the control panel housing and the accumulator. A heat sink is provided on one side of the oil tank, and a thermoelectric power generation device is provided outside the heat sink. The thermoelectric power generation device is connected to a battery. However, the structure of this new modular multi-well wellhead control panel is too simple, and its capacity for accommodating electrical components is poor, which cannot meet the installation requirements of larger wellhead control panels. In addition, it lacks emergency protection equipment for the emergency shutdown system and cannot ensure the safety of the wellhead control panel. The wellhead control panel is hoisted and transported through a single lifting lug structure, and the hoisting stability is poor. Utility Model Content
