Paraffin Scraper, Paraffin Scratcher, paraffin inhibitor，or paraffin cleaner.
Are you searching for paraffin control, or solution for paraffin and mineral scale？
Then, you got the right place.
The Paraffin Scraper , Paraffin Scratcher or Paraffin Cleaner(we name it Automatic Oilwell Paraffin Cleaner, AOPC)is a device that could automatically and continuously eliminate paraffin and mineral scale in wells, using the rod stroke power, without any alteration to the existing pump equipment, and without any additional power, or manual work.
It works independent of the surrounding temperatures and depths of the pump, and adapts very well to petroleum of various physical and chemical characteristics and other natural circumstances for differing territories. Continuously and dynamically working, the Paraffin Scraper eliminates paraffin essentially in the whole oil channel and thus secures the pump with a steady (even decreased) load and an electric current. Simultaneously, it can eliminate such condensed things such as mineral scales, salt, dirt, scum and colloid that cannot be removed in any other way. It has simplified as much as possible the procedure of eliminating paraffin and has secured the steady output - even increased the output of oil.
The scraper can work instead of the huge equipment and personnel needed for hot washings of paraffin; therefore saving energy, reducing charges, and prolonging the period of inspection of the pump to increase efficiency of oil exploitation.
With the help of the Paraffin Scraper, petroliferous layers will not be polluted, and there will be no loss of pressure; oil resources are preserved and the procedure of scientific production of petroleum is advanced.
The principles of work of the Paraffin Scraper include walking tongue-shaped springs which clamp the pump rod, transferring energy from a stroke of the rod to simultaneously drive the Paraffin Scraper and blades at both edges of the cutter to scrape off such condensed things from the wall of the oil pipe; such as the paraffin, colloid, scum and salty dirt. While a stroke of the rod is finished and the rod is on the way back, the Paraffin Scraper is stopped by reversing fingers, supporting on walls of the pipe, so that the rod glides through the walking tongue-shaped springs on the way back, and the coupling of the rod by itself opens and passes through walking tongue-shaped springs. In this process all the condensed material on the rod are scraped and eliminated.
The mechanism includes top reverse, bottom reverse, and the safety unit. Top reverse includes a reversing body and an elastic stopping ring, while the bottom reverse includes a reversing body and a rigid stopping ring. The safety unit includes the adsorbing cylinder and strong magnetic block. |
