The SCG scraper is used to remove various contaminants and deposits from the inner surface of pipes, including pipelines, drill and casing strings. This is important to ensure normal fluid flow and prevent blockages.
Prevent corrosion and scale buildup:
Regular pipe cleaning helps prevent corrosion, accumulation of paraffins, salts, sludge and other deposits that can adversely affect well performance.
Preparing pipes for further operations:
Cleaned pipe ensures stable system operation and prepares equipment for the next drilling or operating steps, such as cementing, casing or drilling tools.
Operating principle of the SCG scraper:
Hydraulic mechanism:
The scraper is equipped with a hydraulic drive that generates the necessary pressure to effectively clean the inner walls of the pipes. The hydraulic system allows the force required to remove contaminants to be adjusted without damaging the pipe.
Downhole operation:
The scraper is lowered into the borehole and, using hydraulic force, cleans the surface of the pipes. It can be used during both the drilling and operating phases of the well.
Contaminant collection:
Sediments and contaminants that are removed from the pipe walls are collected and pushed to the surface where they can be filtered or disposed of.
Advantages of using the SCG hydraulic scraper:
Efficient cleaning: Provides quality pipe cleaning of sludge, waxes, sludge and other contaminants, which improves equipment efficiency.
Maintains normal flow: Removes obstructions to fluid flow in pipelines, preventing blockages and ensuring stable well operation.
Pipe and Equipment Durability: Regular cleaning prevents corrosion and pipe damage, which extends equipment life and reduces repair and replacement costs.
Versatility: Used for both drill string and casing, providing flexibility in application.
Reduced risk of accidents: Pipe cleaning reduces the likelihood of accidents associated with pipe clogging and well disruption.
