数学形态学在地震裂缝检测中的应用

裂缝性油气藏中的裂缝带检测研究是当今地质研究热点之一，到目前为止还没有一套系统完整的裂缝找油气理论和预测方法。经过近２０年的探索，发现准确地预测裂缝仅靠地震勘探是不易办到的，还必须借助地质、测井、地震、信号处理、数字图像处理等学科的综合应用。为此，将数学形态学边缘检测方法引入到地震数据处理中，进行了裂缝发育带的检测，通过选择合适的结构元素，构造形态边缘检测算子，求取图像边界信息；并将此方法分别用于数值模拟实验和实际资料的处理，其结果表明：数学形态学用于地震裂缝带检测是可行的，并且检测效果良好。

APPLICATION OF MATHEMATICAL MORPHOLOGY TO SEISMIC FRACTURE DETECTION

Study on fracture zone detection of fractured reservoirs is nowadays one of the research hotspots in geology. However，there is no systematic and complete theories and methods existed for oil and gas searching in fractured reservoir so far. After nearly 20 years' exploration, it has been discovered that only depending on seismic exploration is difficult to predict fractures accurately, and subjects such as geological, logging, seismic data，signal processing and digital images processing should be also comprehensively applied. For this reason, by introducing edge detection, based on mathematical morphology, into seismic data processing, fracture development zone has been detected. Then through selecting suitable structure elements, morphology edge has been created to detect operators, so as to obtain the image edge information. The method has been applied to numerical simulations as well as practical data processing, and results showed that applying mathematics morphology to seismic fracture detection is feasible and has excellent detection result.
