Heavy oil diluting tank for oil exploitation

Abstract

The invention discloses a heavy oil diluting tank for oil exploitation. The heavy oil diluting tank comprises a main body tank, a high-pressure steam water tank and a motor. A circular base is mountedat the lower end of the main body tank; the high-pressure steam water tank is fixedly mounted in the main body tank through a high-pressure steam water tank fixing frame; the upper end of the high-pressure steam water tank communicates with a water inlet pipe penetrating through the main body tank; first evaporating pipes are mounted on the inner wall of the side end of the high-pressure steam water tank, and a second evaporating pipe is mounted on the inner wall of the bottom end of the high-pressure steam water tank; steam pipes communicating into the circular base are mounted at the upperend of the high-pressure steam water tank; the steam pipes communicate with injection pipes penetrating through the circular base; the motor is fixedly mounted on the inner wall of the bottom end of the main body tank through a motor fixing frame, and an output shaft of the motor penetrates through the main body tank to be connected with a rotating shaft; and the rotating shaft is rotatably mounted in the central position of the lower end face of the main body tank, and stirring discs are mounted on the rotating shaft. The heavy oil diluting tank has the advantages that heavy oil is quickly diluted and mixed, the viscosity of the heavy oil is decreased, and the exploitation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a heavy oil dilution tank for petroleum exploitation. Background technique [0002] Oil extraction refers to the act of digging and extracting oil in places where oil is stored. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. Heavy oil is crude oil with high asphaltene and colloid content and high viscosity. Usually, crude oil with a surface density greater than 0.943 and an underground viscosity greater than 50 centipoise is called heavy oil, because of its high density, it is also called heavy oil. In addition to high viscosity, heavy oil has high density and poor fluidity. It is difficult to extract such viscous oil from the ground. At present, heavy oil production needs to be transported by high-power pumps, and in order to achieve a reasonable pump Th...

Problems solved by technology

In addition to high viscosity, heavy oil has high density and poor fluidity. It is difficult to extract such viscous oil from the ground. At present, heavy oil production needs to be transported by high-power pumps, and in order to achieve a reasonable pump The delivery volume requires heating or dilution of the delivery system, which consumes a lot of energy

The heavy oil dilution equipment cannot efficiently dilute and mix the heavy oil, which reduces the efficiency of oil extraction
