随着水平井技术的大量应用,电阻率测井在测量水平井和大倾斜井中起主导作用。而人们往往沿用传统的测井解释方法来解释水平井测井曲线,而水平井测井与一般直井测井相比,其测井空间、物理环境和响应有诸多不同,特别是电阻率曲线会受到地层电阻率各向异性的严重影响,因此需要对经校正后的测井响应更能反映地层真电阻率,通过本文方法校正后,校正后的电阻率曲线更能反映出薄互层中的砂岩特性。
With the extensive use of horizontal well technology, resistivity logging plays a leading role in the measurement of horizontal wells and large inclined wells. However, people often interpret horizontal well logs using traditional well logging interpretation methods. Compared with normal well logs, horizontal well logging has many differences in logging space, physical environment and response. In particular, the resistivity curve Which is seriously affected by the resistivity anisotropy of the formation. Therefore, it is necessary to reflect the true resistivity of the formation after the correction of the well logging response. After correction by this method, the corrected resistivity curve can better reflect the Sandstone characteristics.
