Solar Microwave Heating Waveguide Oil Pipeline

Abstract

The invention discloses a solar microwave heating waveguide oil delivery tube which comprises a power part and a plurality of delivery parts sequentially connected and communicated in series. The power part comprises a solar cell panel for providing electric energy, each delivery part comprises an emitting unit, a waveguide unit and a delivery unit, the delivery units and the waveguide units are all communicated and connected in the axial direction of the oil delivery tube and alternatively arranged, the emitting units are arranged on the side walls of the waveguide units to form tubular waveguide lossless connection, the power part is connected with the emitting units to provide power for the emitting units, the emitting units generate microwaves, and the microwaves are emitted into the waveguide units to heat thickened oil in the waveguide units. According to the solar microwave heating waveguide oil delivery tube, solar energy is used, damage to the environment is avoided, the heating process and the delivery process are synchronously carried out in the same tube, in this way, the heating procedure is simplified, meanwhile, immediate heating is achieved, heat losses and waste are avoided, and the solar microwave heating waveguide oil delivery tube is used for underground thickened oil exploration and is high in delivery efficiency.

Description

technical field [0001] The invention relates to the field of exploration and production of shale oil and gas, in particular to a solar microwave heating waveguide oil pipeline. Background technique [0002] 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. The water content of heavy oil is low, and the viscosity changes significantly with the change of temperature, such as the temperature increases by 8-9. Viscosity can be reduced by half. Therefore, for the exploitation and transportation of heavy oil, thermal power is often used to reduce its viscosity, such as steam drive, thermal oil circulation, and burning oil layer, etc.; it can also be mixed with thin oil, emulsified, and active agent is added to reduce its viscosity. At the temperature o...

Problems solved by technology

The above two factors lead to the increase of viscosity of the heavy oil itself caused by the decrease of temperature, which affects the flow speed and resistance, which is an urgent problem to be solved in the transportation process

The existing method of inputting steam underground to heat-melt the oil body is too direct, coupled with the water content and heat absorption of the formation and oil body, the loss and consumption of the huge heat carried by the steam has become an important energy waste problem
