Description

Reducing pigging device for blocking and positioning pipeline

Technical Field

The utility model relates to a reducing pigging device for stifled location of pipeline card belongs to oil gas warehousing and transportation engineering field.

Background

The pipeline cleaner regularly carries out paraffin removal operation on the long-distance pipeline, is favorable for maintaining the conveying efficiency of the pipeline, and avoids the pipe condensation accident possibly caused by long-time paraffin blockage in winter. The pipe cleaner with a special structure is required to be designed for cleaning the pipes with the variable diameter pipelines, and the requirements of cleaning the pipes with different diameters can be met simultaneously. The pipelines in China are numerous, and a large number of reducing pipeline cleaning operation requirements exist, for example, a special reducing pipe cleaner is adopted for Ke Du pipe.

However, in the pipe cleaning process of the prior reducing pipe cleaning device, the blockage phenomenon still occurs sometimes. Every time a pig is blocked, a pig with a positioning function needs to be sent again. The secondary pipe cleaner pushes the blocking pipe cleaner to correct the posture, but the blocking pipe cleaner cannot play a role in blocking every time. Therefore, in the case of failure of the initial attitude correction, accurate positioning is performed based on the tracker carried by the vehicle. Even the pipeline needs to be rush-repaired by operations such as hole punching under pressure, welding cut repairing and the like.

Meanwhile, the situation that the leather cup is seriously abraded after the pipe cleaner is recovered also often occurs, which also indicates that the blocking probability of the pipe cleaner caused by the abrasion of the leather cup is very high. On the basis, the operation posture of the pipe cleaner in the pipeline is possibly changed due to the influence of any one factor of the increase of the wax accumulation amount of the pipeline, the change of the roughness of the pipe wall, the bulge in the wall or the flow state of crude oil, and the like, so that the blockage accident is caused.
