Immersion piston for producing crude oil and liquids from boreholes

Patent:

Abstract

When using a free piston to pump an oil well, oil and gas accumulates above and below the piston; upon venting the gas pressure above the piston, the gas pressure below it drives the piston and the oil above it to the surface. In the past, such pistons were too heavy and did not run tight in the tubing, causing loss of efficiency and high gas consumption. According to this invention, the piston is made of aluminum or plastic; it consists of at least 2 parts flexibly connected by wire rope or plastic strings, and is equipped with a labyrinth gasket and a paraffin scraper.
