Description

Technical Field

[0001] This utility model belongs to the technical field of crude oil transportation equipment, specifically relating to a digital pipeline ball take-up machine. Background Technology

[0002] In oilfields, oil is transported via pipelines to gathering stations or centralized processing stations after production. When crude oil is transported at excessively low temperatures for extended periods, large amounts of paraffin wax precipitate and adhere to the inner walls of the pipelines. Over time, this reduces the pipeline's cross-sectional area and can even cause severe blockages, increasing pipeline resistance, pressure, pump pressure, and power consumption, thus affecting crude oil transport. Therefore, workers need to visit the well site daily to insert dewaxing balls into the pipelines. During this dewaxing ball-dropping operation, rubber balls slightly smaller than the pipeline's inner diameter are typically inserted. Under oil pressure, the balls move towards the gathering station, squeezing and removing the paraffin wax deposited on the pipeline walls. Finally, the balls are collected at the gathering station or the end of the pipeline using a ball-retrieving device, thus clearing the pipeline blockage. During oil pipeline transportation, the low temperature causes paraffin wax in the crude oil to slowly precipitate and solidify on the pipe wall. Over time, the inner diameter of the pipeline decreases, increasing pipeline resistance, pressure, flow rate, and power consumption. In some cases, the pipeline may even become completely blocked, directly affecting crude oil production. This led to the development of ball-feeding machines, which were subsequently followed by ball-retrieving machines.

[0003] Currently, most ball collection devices are manually operated, which is inconvenient. Workers need to manually collect the balls daily, tightening numerous screws; the process is cumbersome and labor-intensive. The crude oil disposal process is also difficult, as crude oil can easily leak during operations, causing environmental pollution, poor sanitation, and increased workload and labor intensity. Furthermore, there is a lack of effective disposal methods for the recovered crude oil. If a dedicated crude oil treatment device were installed, additional equipment and a dedicated sealed room would be required, posing certain safety hazards. Utility Model Content

[0023] The digital pipeline ball collecting machine provided by this utility model works as follows: The dewax-removing balls first enter the ball-loading tank 4 through the oil inlet pipe 33 and the ball reading system 11.

When the ball loading tube 5 is aligned with the ball loading tube 36, the dewax-removing balls in the ball loading tube 5 and the liquid in the ball loading bucket 4 fall into the oil tank 9 under the action of gravity, realizing one-click ball collection. Next, the balls are drained of oil through the oil grate 13 in the oil tank 9. After the balls are collected, the electric ball loading valve 6 is closed and the hydraulic oil pump 8 is started. The hydraulic oil pump 8 sends the liquid in the oil tank 9 to the oil outlet pipe 34 through the oil drain pipe 29. At the same time, the electric oil inlet valve 2 and the electric oil outlet valve 3 are started, and the electric bypass valve 1 is closed to realize normal oil transportation. Finally, when the dewax-removing balls have drained the crude oil in the oil tank 9, the ball loading gate 23 on the oil tank 9 is opened manually to release the dewax-removing balls, ready for the next use. When the wax removal ball passes through the ball reading system 11 on the oil inlet pipe 33, the ball reading system 11 reads the ID number on the chip implanted in the wax removal ball and combines it with the address on the PLC in the PLC control box, and then transmits the ball receiving information to the oilfield pipeline operation and management system.
