Background
Today, the technology is rapidly developed, and the oil and gas well production platform is gradually changed from a manual guard to an intelligent unmanned platform. This progress is made on the basis of an adequate supply of electrical energy. Electric energy plays an important role as a clean and efficient energy form in modern society and industrial production, and has important significance for pushing energy transformation and sustainable development. Electrical energy is typically converted from other forms of energy into electrical energy using a generator. Generally, at the wellhead of an oil and gas well, fluid generally has higher kinetic energy, and the fluid is converted into electric energy and utilized, so that the problem of difficult electricity utilization in a remote well site can be effectively relieved.
According to faraday's law of electromagnetic induction, when a magnetic flux in a conductor changes, an induced electromotive force is generated in the conductor, thereby generating a current. Magnetic flux is the number of lines of force of a magnetic field passing through a surface of a conductor and is related to the strength of the magnetic field and the area of the conductor perpendicular to the magnetic field.
Currently, most wellhead platforms generate electricity by themselves in the well by using mechanical energy generated by high-energy fluid injected into the well or sucker rods moving in the well.
