利用LWD曲线实时评价地层，可以确保水平井井眼在储层中的有效延伸，提高钻遇率。

Real-time evaluating the stratum by the using LWD (Logging While Drilling) curve could ensure horizontal borehole extend effectively in the reservoir bed and improve rate of drilling.

由于这些模型采用滤波器组模拟对比度敏感函数(CSF)，增加了视觉阈值获取和实时评价算法的复杂度。

As filter Banks are used to simulate the contrast sensitivity function (CSF) in these models, the complexity of visual threshold obtainment and real-time (assessment) algorithms are increased.
