| 摘 要： | 北黄海盆地是发育于中朝地台之上的中新生代含油气盆地。中生界砂岩储集层以特低孔特低渗为基本特征，裂缝是已发现油流的主要储集空间。根据盆地的三维地震、岩心及成像测井资料，采用最新的全局寻优算法的FracPM曲率技术，结合蚂蚁追踪技术，实现了裂缝的高精度成像，从大小尺度两个层面，对中生界目的层的裂缝发育程度和分布状况进行了预测，并取得良好的应用效果，在预测的裂缝发育层段钻获较好的油气发现。

| Abstract: | The North Yellow Sea basin on the Sino-Korean plateau is a Mesozoic-Cenozoic fault basin. The Mesozoic sandstone reservoirs featuring low permeability nature are proved to be the main exploration targets by drilling, and fractures inside are found to be the main reservoir space of the discovered oil pools. Based on the 3D seismic, core observation and imaging well logging data, this paper, by means of the latest FracPM curvature analysis with the characteristic of global optimization algorithm, combined with the ant?tracking method， achieves the high precision imaging of fractures. At the levels of big and small scale, the fracture growth level and distribution of the exploration targets are predicted, and good practical effects are obtained. The predicted fractured layers are proved by drilling with great hydrocarbon potentials |
