准确定位对于水平井和超深井是至关重要的。定向井测量和地震数据的不确定性会导致错误的井迹定位。地质定位随钻测井借助井筒声波反射技术,可以直接测量出井筒与关键液面及与其平行的地层界面的位置关系。径向探测距离已由当前地质导向工具的几米延伸到20m左右。实物研究原型
Accurate positioning is crucial for horizontal wells and ultra-deep wells. Uncertainties in directional well measurements and seismic data can lead to erroneous well location. Geological Positioning LWD With wellbore acoustic reflection technology, we can directly measure the position relationship between the wellbore and the critical liquid surface and its parallel interface. The radial detection distance has been extended from a few meters of the current geosteering tool to about 20m. Physical research prototype
