摘要
对商河油田商四区沙三中火成岩裂缝体系进行了分析研究,利用岩石物理测试系统,对不同尺度裂缝与纵波的振幅、速度和主频等参数间的关系进行了理论测试研究。引入图像处理中的多尺度边缘检测等技术,结合三维地震资料的特点,利用相邻地震道之间的相异性进行裂缝预测,描述和刻画地下空间某一区域的裂缝和孔洞的展布形态。
The system of igneous rock cracks of Shasanzhong formation in Shang-4 area of Shanghe oilfield is studied. By the lithological physical testing system, the relationship between varied size cracks and parameters of longitudinal wave, such as amplitude of vibration, velocity, main frequency and so on, is studied. Using the varied size margin detecting technology, combining with the features of 3-D seismic data, the crack system is forecasted and the distribution of cracks and holes in some area in underground space is described and portraied.
