Petroleum mechanical device suitable for heavy oil exploitation

Abstract

The invention discloses a petroleum mechanical device suitable for heavy oil exploitation, the petroleum mechanical device comprises a tank body, wherein the tank body comprises a metal frame and an outer frame which are arranged inside and outside and are hermetically and fixedly connected with each other. A built-in cavity is formed between the metal frame and the outer frame; an electromagneticinduction coil which is arranged in a spring shape is arranged in the built-in cavity; one end of the electromagnetic induction coil is connected with an electromagnetic heating controller. The electromagnetic heating controller is connected with a mains power supply; and the other end of the electromagnetic induction coil is connected with the mains power supply. The upper end of the tank body is fixedly connected with a support rod, the upper end of the support rod is rotatably connected with a cross rod, the left end of the cross rod is fixedly connected with a motor rod, and the lower endof the motor rod is fixedly connected with a stirring motor. According to the invention, a mixed liquid of heavy oil and water can be quickly stirred and mixed, the heating efficiency is improved through an electromagnetic heating mode, and the problem of blockage caused by impurities flowing out through a liquid outlet pipe is avoided.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a petroleum mechanical device suitable for heavy oil exploitation. Background technique [0002] Heavy oil is crude oil with high asphaltene and colloid content and high viscosity. Crude oil with a relative density greater than 0.92 (20°C) and an underground viscosity greater than 50 centipoise is usually called heavy oil. Because of its high density, heavy oil is also called heavy oil. [0003] Heavy oil is often mixed with a lot of liquid water after being exploited by various mechanical equipment, and then it is transported to the storage tank. In order to reduce its viscosity, it is usually heated, but due to the uneven mixing of heavy oil and water , often lead to different heating degrees, some heavy oils have good fluidity, and some heavy oils have poor fluidity, which cannot meet the transportation conditions; in addition, in the traditional technology, e...

[0003] Heavy oil is often mixed with a lot of liquid water after being exploited by various mechanical equipment, and then it is transported to the storage tank. In order to reduce its viscosity, it is usually heated, but due to the uneven mixing of heavy oil and water , often lead to different heating degrees, some heavy oils have good fluidity, and some heavy oils have poor fluidity, which cannot meet the transportation conditions; in addition, in the traditional technology, electric heating plates, electric heating tubes and other heating components are used to heat the heavy oil through heat conduction. Heating with water leads to large heat loss and high energy consumption; and in the process of transporting the mixed liquid of heavy oil and water, there are often a small amount of impurities blocked in the pipeline, which affects the normal transport
