介绍一种油井井下参数（压力、温度）无线测试的数据信息传输方法及井下发射装置低功耗控制电路。在不停产的情况下，对井下参数进行长期监测，获得确切可信的第一手资料以便对油井施行相应的增产措施。
A data transmission method for wireless testing of downhole parameters (pressure and temperature) of oil well and a low power consumption control circuit of a downhole launching device are introduced. In the case of non-stop production, long-term monitoring of the parameters of the underground to obtain credible first-hand information in order to implement the appropriate stimulation of the well.
