Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] A pipe support device used in the technology of raising a well drilling deviated well, such as Figure 1~2 As shown, it includes an upper half pipe collar 1 and a lower half pipe collar 6, and both the upper half pipe collar 1 and the lower half pipe collar 6 are semicircular. The two ends of the upper half pipe collar 1 and the lower half pipe collar 6 are respectively provided with connecting ends, and the connecting ends of the upper half pipe collar 1 and the lower half pipe collar 6 are connected by bolts 3 to form the whole pipe collar and are sleeved on On the outside of the pipe; th...

The invention relates to a pipe supporting device for an inclined shaft raise boring technology. The device comprises an upper half pipe hoop and a lower half pipe hoop, connection ends are arranged at the two ends of the upper half pipe hoop and the two ends of the lower half pipe hoop respectively, the connection ends of the upper half pipe hoop and the connection ends of the lower half pipe hoop are connected through bolts to form a whole pipe hoop, and the whole pipe hoop sleeves the outer side of a pipe; a rubber cushion layer is further arranged between the whole pipe hoop and the pipe;multiple supporting teeth are evenly arranged at the other side of the circumference of the whole pipe hoop. According to the pipe supporting device, the pipe hoop is assembled with the rubber cushionlayer and the pipe through bolts, the pipe is effectively isolated from the shaft wall through the supporting teeth welded to the pipe hoop, laying installation of the pipe is guaranteed, and the pipe supporting device has the advantages of being simple in structure, convenient to operate and reliable and stable in supporting. When the pipe is laid along an inclined shaft, the pipe is effectivelyinstalled and protected through the pipe supporting device.
Description
technical field [0001] The invention relates to a pipeline support device used in the technique of raising an inclined well. Background technique [0002] As for the pipeline raising drilling project, only the raising drilling case of Saipan Company abroad published some project information at the International Pipeline Conference (IPC), but there was no detailed design and construction plan; no domestic pipeline project using raising drilling was found. Drill case. [0003] After the raise drilling deviated well is completed, the pipeline needs to be laid and installed along the completed well wall, and the protective device needs to be supported between the pipeline and the well wall, so as to successfully complete the installation and protection of the pipeline. Contents of the invention [0004] In order to solve the above problems, the purpose of the present invention is to provide a pipeline installation support device, which is suitable for inclined wells with cros...
