目前，使用一种专门设计的随钻测井（LWD）仪器──近钻头电阻率测量仪即可实时计算地层倾角，这种测量仪可以通过丝扣直接安装在钻头内，但也可以下在钻柱中的任何位置。随着该测量仪的转动，一对磁力检测该测量仪相对于地球磁场的方位，因而可以记录下方位正确的电阻率图像以及伽马射线测量值。新的计算方法使得近钻头电阻率测量仪能够在钻井过程中进行视倾角计算，该测量仪以3min的时间间隔计算视倾角方向、倾斜幅度以及质量系数，这些数据被传送到地面并以视倾角和真倾角的方式显示出来，且提供的数据准确、及时，对井眼轨迹可进行实时修正。由于局部构造倾斜可以会不同于用大比例地图或地震剖面图所做的预测，所以，视倾角计算可用于确定钻井方案或实时修改钻井作业。
Stratigraphy dip rates can now be calculated in real time using a specially designed Logging While Drilling (LWD) instrument, a near-bit resistivity meter, which can be installed directly in the drill bit with a threaded fastener but can be Anywhere in the drill string. As the gauge rotates, a pair of magnetic forces detect the orientation of the gauge relative to the Earth’s magnetic field, thus allowing the correct orientation of the resistivity image and gamma ray measurements to be recorded. The new calculation method allows near-bit resistivity meters to perform a dip calculation during drilling, which calculates the dip direction, the tilt amplitude, and the mass coefficient at 3-minute intervals, which are transmitted to the ground and measured at an apparent dip And the true inclination of the way shown, and the data provided accurate and timely, real-time correction of wellbore trajectory. Since local tectonic tilt can be different from predictions made with large-scale maps or seismic profiles, the dip calculation can be used to determine a drilling program or to modify a drilling operation in real time.
