Problems solved by technology
[0003] In the process of oil extraction, since oil drilling rigs and workover rigs will generate strong vibrations, the wellhead at the extraction site will also vibrate accordingly. In addition, due to the existence of wind in the field environment, it will cause the upper pipe string to shake or damage Buckle difficulty and other problems, resulting in the efficiency of machine work is also affected

The invention discloses a wellhead device integrating functions of drill string buckling devices and splash-proof boxes. The wellhead device integrating the functions of the drill string buckling devices and the splash-proof boxes comprises a support, two hydraulic cylinders and the two splash-proof boxes, wherein the two hydraulic cylinders and the two splash-proof boxes are symmetrically mounted on the support, the two hydraulic cylinders are divided into a left hydraulic cylinder and a right hydraulic cylinder, the two splash-proof boxes are correspondingly a left splash-proof box and a right splash-proof box, a left upper cover plate is mounted on the left splash-proof box, and a right upper cover plate is mounted on the right splash-proof box; the support is mounted on a wellhead tubing tong and moves front and back along with the tubing tong, and the left buckling device, the right buckling device, the left splash-proof box and the right splash-proof box are connected into a whole through the cylinder rod end of the left hydraulic cylinder and the cylinder rod end of the right hydraulic cylinder; oil receiving pipes for filtering oil are detachably mounted below two oil drainage holes correspondingly. According to the wellhead device integrating the functions of the drill string buckling devices and the splash-proof boxes, the shaking of an upper pipe string and difficult buckling caused by mechanical vibration and field environment wind can be effectively prevented, the working efficiency is improved, and the labor intensity is reduced.
Description
technical field [0001] The invention belongs to the technical field of wellhead operation automation of petroleum drilling rigs and workover rigs, and in particular relates to a wellhead device integrating the functions of a drill string stabbing device and a splash-proof box. Background technique [0002] Petroleum is an important energy source used in the development of my country's national economy. Compared with coal, petroleum has a high energy density (the heat of combustion of oil of equal weight is 50% higher than that of standard coal), convenient transportation and storage, and a degree of pollution to the atmosphere after combustion. Smaller and other advantages. Fuel oil extracted from petroleum is the main fuel for various kilns in transportation vehicles, power station boilers, metallurgical industry and building materials industry. [0003] In the process of oil extraction, since oil drilling rigs and workover rigs will generate strong vibrations, the wellhead...
