Description

Technical Field

[0001] The present invention belongs to the technical field of crude oil transportation equipment, specifically relates to a digital pipeline pig receiver device, and also relates to a digital pipeline pig receiving method. Background Art

[0002] After oil production in each oilfield, the gathering and transportation method is to use pipelines to transport to the gathering station or centralized treatment station. When the long-term transportation temperature of crude oil is too low, a large amount of paraffin in the crude oil will precipitate and adhere to the inner wall of the oil pipeline. Over time, the pipeline cross-section will decrease, and even seriously block the oil pipeline, increasing the pipeline resistance, pipeline pressure, pump pressure, and power consumption, thus affecting the transportation of crude oil. Therefore, workers need to go to the well site every day to throw balls into the oil pipeline for wax removal. In the wax removal ball-throwing operation, generally, rubber balls slightly smaller than the inner diameter of the pipeline are thrown into the pipeline. During the movement of the rubber balls towards the gathering station under the action of oil pressure, the paraffin condensed on the inner wall of the oil pipeline is squeezed and removed, and finally, the rubber balls are collected through a pig receiver device at the gathering station or the end of the pipeline to achieve the purpose of dredging the pipeline. During the transportation process of the oil pipeline, affected by low temperature, paraffin in the crude oil will slowly precipitate and solidify on the pipe wall. As time goes by, the inner diameter of the pipeline becomes smaller and smaller, the pipeline resistance increases, the pressure increases, the flow rate decreases, and the power consumption increases. Sometimes, it even becomes completely blocked, directly affecting crude oil production. Therefore, the appearance of the ball-throwing machine led to the emergence of the pig receiver.

[0003] At present, most pig receiver devices are manually operated, which is rather inconvenient. Workers need to manually receive the balls every day, tighten a large number of screws, and the operation process is cumbersome, with a high labor cost. The crude oil discharging link is rather difficult, and the crude oil is likely to leak during the operation, resulting in environmental pollution at the site, poor sanitation conditions, increasing the workload and labor intensity of workers. In addition, there is a lack of effective disposal methods for the recovered crude oil. If a special crude oil treatment device is set up, relevant equipment needs to be additionally configured and a special sealed room needs to be set up for disposal, which poses certain potential safety hazards.
