Abstract: To avoid collision accident of group drilling, the group drilling anti-collision monitoring and alert system is designed. According to the propagation rule and characteristics of vibration wave in the formation and the change of vibration signal, the system could predict whether the bit approaches the offset well or not, corresponding software and hardware equipment is developed. Through the application in Bohai Oilfield, it proves that shallow drilling anticollision monitoring and alert is attended with good results. It is shown that the technology could improve cluster drilling effectively.
