The invention belongs to the technical field of field downhole operations, and particularly relates to a wellhead supporting device for hanging a falling protector. A hollowed cuboid wellhead basic support is formed by twelve hollowed round pipes and 18 pairs of fasteners, every four transversely-placed hollowed round pipes form a group, every two adjacent transversely-placed hollowed round pipesare perpendicular to each other and placed to form a square, the hollowed cuboid wellhead basic support is divided into an upper layer and a lower layer and is kept relatively parallel, and the four vertically-placed hollowed round pipes are placed at the four right angles of a square plane respectively. The vertically-placed hollowed round pipes are perpendicular to the upper plane and the lowerplane formed by the transversely-placed hollowed round pipes. Each pair of the fasteners is of a double-ring-shaped structure capable of rotating relatively. One ends of the fasteners are connected with the vertically-placed hollowed round pipes, and the other ends of the fasteners are connected with the adjacent transversely-placed hollowed round pipes. A supporting pipe is installed on the fourtransversely-placed hollowed circular pipes on the lower-layered plane of the basic support, and the lower end of the supporting pipe is connected with a supporting pipe circular ring. The supportingdevice is fixed at a wellhead, so that the falling protector is convenient to hang, and the safety of an operator is effectively guaranteed.
本发明属于现场井下作业技术领域,具体涉及一种用于防坠器吊挂的井口支撑装置。由十二根空心圆管和18对扣件构成镂空长方体井口基本支架,横放的8根空心圆管每四根为一组,相邻两横放的空心圆管互相垂直,摆放成正方形,分为上下两层且保证相对平行,立放的4根空心圆管分别放置于正方形平面的四个直角,且垂直于横放的空心圆管形成的上下两个平面;每对扣件为可相对旋转的双环形结构,其一端与立放的空心圆管连接,另一端与相邻的横放的空心圆管连接;在基本支架下层平面的四根横放的空心圆管上安装一根支撑管,支撑管的下端连接支撑管圆环。通过将该支撑装置固定在井口,便于吊挂防坠器,有效保障操作人员的安全。
