Oil separator

Abstract

The invention discloses an oil separator. The oil separator structurally comprises an inlet tank, a separation tank, an oil outlet pipe, a water outlet pipe and a gas outlet pipe. The inlet tank is fixedly installed at the upper end of the separation tank, and runs through the separation tank; and the bottom of the separation tank is fixedly provided with the water outlet pipe. An extrusion ring is extruded through heavy oil in the flow process, and a rotating rod is driven by a thread frame to rotate; the rotating rod is rotated on a guide ring smoothly, so that vortex is generated; the temperature of the heavy oil is increased through a heating rod; thus, the fluidity of the heavy oil is improved; a part of heavy oil adheres to the inner wall of the inlet tank, and gas is generated through the heavy oil in the separation tank; the gas enters a gasbag through a gas inlet; at the moment, push rods at the two ends are driven by the gasbag to move downwards, and the heavy oil adhering tothe inner wall of the inlet tank is scraped through a laminating plate downwards; at the moment, air bubbles formed at the upper layer of the heavy oil are punctured through burrs; and the gas separation effect is improved.

Description

technical field [0001] The present invention relates to the petroleum field, more specifically, relates to an oil separator. Background technique [0002] The sediment (wax cake) produced in the production process of the oil well is usually solid or semi-solid, and the main component is paraffin. The sediment makes the crude oil have a high viscosity. Separation of oil, gas and water, but because the heavy oil contains more paraffin, the temperature of the oil flow from the bottom of the well to the wellhead during the production of the oil well gradually decreases, and the paraffin forms wax crystals, which are continuously precipitated, causing the heavy oil to solidify , to increase the viscosity of the heavy oil. When the heavy oil enters the oil separator, the circulation of the oil inlet pipe on the oil separator is weakened, and the oil inlet pipe is prone to reverse flow, and the heavy oil is easy to adhere to the inner wall of the oil separator, resulting in thick ...
