利用常规测井曲线进行裂缝预测有多种方法,例如曲线变化率、深浅电阻率比值等几十种方法,但是每种方法在实际应用时,各有利弊,为此可以使用综合概率法进行裂缝预测。本文首先介绍了基于综合概率法的测井资料裂缝预测的基本步骤,然后对一段实测的声波测井曲线进行应用,发现该方法对目的层段的裂缝具有良好的预测效果。 There are several methods for predicting fractures using conventional well logs, such as the rate of change of the curve and the ratio of resistivity to depth. However, each method has its advantages and disadvantages in practical application. For this purpose, the integrated probability method can be used to crack prediction. This paper first introduces the basic steps of the fracture prediction of logging data based on the synthetic probabilistic method, and then applies a section of measured acoustic logging curve to find that the method has a good prediction effect on the fracture of the target layer.
