AI Technical Summary

Technical Problem

In layered water injection technology, the efficiency and reliability of wireless two-way communication between each layer downhole and the wellhead are low, and it is severely affected by formation characteristics.

Method used

By acquiring the formation water absorption characteristic curve information of each downhole water distributor, the target formation is determined, and an acoustic signal generator is used to emit an acoustic signal, which is transmitted to the target water distributor, converted into a pressure pulse signal, and sent to the wellhead controller to obtain the characteristic parameters of the reference formation.

Benefits of technology

It improved the overall well communication efficiency, enhanced the communication reliability of some layers, and solved the problems of low communication efficiency and poor reliability.

Abstract

本发明公开了一种无线分层注水通讯方法、装置、电子设备和存储介质。该方法包括:获取目标井下各配水器对应地层的吸水特性曲线信息,根据吸水特性曲线信息确定目标地层,接收获取参考地层的特征参数的指令,控制参考地层对应的声波信号发生器发射声波信号;将声波信号传输至目标地层对应的目标配水器,以使目标配水器将压力脉冲信号发送到目标井的井口控制器中,获取参考地层的特征参数,压力脉冲信号为用于指示参考地层的特征参数的信号。本申请在确定了目标地层后,通过声波信号发生器将声波信号传输给目标地层对应的目标配水器,再使目标配水器通过压力脉冲信号将井下数据发送到井口控制器,解决了全井通讯效率低、部分层通讯可靠性差的问题。
