摘要
测井曲线高分辨率处理是提高薄层测井解释精度的一条重要途径.在纵向分辨率匹配技术基础上,利用遗传算法进行测井曲线分辨率处理:先由遗传算法在频率域确定滤波器,然后使用分辨率匹配技术提高测井曲线分辨率.利用该方法对中原油田和新疆塔河油田多口井的八侧向、深感应、自然伽马等多种方法的测井数据进行处理,测井曲线的分辨率得到明显提高,使得其更加适合薄层高分辨率处理解释的需要.
High-resolution processing of well logs is one of the important approaches to enhance the explanations to the thin beds. There are several high-resolution techniques at present. Based on the resolution matching technique and genetic algorithm, the aiming function is first defined, then the resolution of well logs is enhanced with the resolution matching. The well logs such as LL8, ILD and GR of wells in the Zhongyuan oilfield and Tahe oilfield are processed. Those processed logs are more suitable for high-resolution interpretation of thin beds.
