To fully learn the situation in the underground part of the oil well,real time supervision over parameters such as temperature and pressure is necessary in the process of oil exploitation.In this paper,a method of data communication appropriate for the underground oil well condition is proposed.The core of the method is the use of SSC P485 spread spectrum chip and SSC P111 amplifying chip to implement data communication through the power line in the oil well by the low power line carrier technology.Experiments show that this method facilitates the acquisition of data and the knowledge of what happens underground.
