Problems solved by technology

However, during the pigging process, since the static blender is fixed inside the pipeline, the pigging ball cannot pass through smoothly, which limits the applicability of the static blender, especially in the submarine gathering pipeline, how to overcome the pigging ball The problem of not being able to pass through the static blender in the pipeline has always troubled oilfield workers

Embodiment

[0032] When the device is installed, at first thirty-six spine rods 12 are respectively installed on the two elastic backing rings 10. The axial center of the spine rods 12 protrudes toward the inside of the pipeline, and the edges of the two ends of the spine rods 12 face the outside of the pipeline. Buckle the two elastic back rings 10 in the slots 9 of the two fixed collars respectively, and make the thirty-six spine rods 12 evenly distributed on the square slots 11 respectively. The spine rods 12 on the two fixing collars are linked with spine pins 13 respectively.

[0033] Secondly, the upper and lower cover plates of the spring cover module 2 are correspondingly welded to the two ends of the eight springs 15 evenly distributed along the circumferential direction, the fixing ring 19 is welded to the cylindrical sleeve 18, and the upper end of the cylindrical sleeve 18 is welded to the The lower cover is welded.

[0034] Then, the flange inner ring of the upper round tube...

Abstract

The invention relates to an L-shaped static mixing device and a method that allow pigging balls to automatically pass through. The device is composed of an L-shaped cone mixing module, a spring sleeve module and two upper and lower circular pipe sleeve modules. When the heavy oil and thin oil in the pipeline flow through the L-shaped cone mixing module, due to the blocking effect of the L-shaped mixing rod, the fluid in the pipeline will generate turbulent flow. Turbulent flow effect, so as to realize the full mixing of heavy oil and thin oil. When the pigging ball passes, due to the pressure, the L-shaped mixing rod straightens, and the pigging ball passes through automatically. After the pigging ball passes, due to the tension of the spring sleeve module, the L-shaped cone mixing module automatically restores the shape of the L-shaped cone, thereby realizing the uniform mixing of heavy oil and thin oil and the automatic passage of the pigging ball Function.

Description

technical field [0001] The invention belongs to the technical field of laying of crude oil pipeline transportation facilities, and in particular relates to an L-shaped static mixing device and method for automatically passing pigging balls. Background technique [0002] Heavy oil mixed with thin oil transportation technology is an important method for oilfields to reduce drag and increase transportation, and the key technology is how to realize the uniform mixing of heavy oil and thin oil. The mixing method of large tanks and direct blending in pipelines are mainly used in the oil field to realize the mixing of heavy oil and thin oil. Due to the large area occupied by the large tank mixing method, high investment, difficult operation and maintenance, and poor applicability, it is generally not used in new oilfields. With the advancement of process technology, it has become a trend to use the direct blending method in the pipeline to realize the mixing of heavy oil and thin ...
