这是一种坐键式可打捞的正脉冲无线随钻测斜仪,做到了井口投放井底打捞,测量准确,使用方便。仪器采用了经实践检验成熟可靠的正泥浆脉冲技术,并在地面部分使用无线电传输立管压力信号及其他数据参数,使用时不需要布置电缆,方便简洁。井下部分短节之间也采取无线通讯,连接操作方便,解决震动过程中传统插针结构带来的隐患。
This is a retrievable Mud Pulse MWD, which can be dropped at the top of the well and retrieved from the bottom of the well. The instrument uses mature and reliable positive mud pulse technology and transmits stand pipe signals and other parameters by radio on the ground. When using, it does not need to lay out cables. The down-hole modules communicate wirelessly and the connection is easy and convenient, avoiding the hidden trouble arising from traditional contact pin structure during vibration.
