Based on the modern technology of low voltage power line carrier,we make a fundamental study of the communication between the land surface part and the underground part of the oil well.We solve the problem of power line noise interference through spread spectrum communications and improve the coupling circuit,especially the filter in the front part of the coupler,in view of cycling frequency interference.Specially,we construct the trans-receiving system for the oil well with the SSCP485 chip (spread spectrum carrier),the SSSCP111 and PIC18 MCU.The experiment shows that the system is reliable and stable in the aspects of data transmission,receiving and processing.

Key words: power line carrier;spread spectrum carrier communication;oil well;power line couple tech SSCP485
