三维可视化解释技术是一项全新的地震解释技术,与传统的地震资料解释有着本质的不同,它是从三维可视化显示出发,以地质体或三维研究区块为单元,采用点、线、面和体相结合的数据体空间可视化解释。该技术结合相干体技术可进行复杂断层的解释与组合;应用空间域层位自动追踪技术能够准确落实构造形态;采用目标雕刻技术,利用反演数据体可实现立体透视岩性体的空间展布及厚度趋势。将该技术应用在大港油田官西地区复杂断块构造解释和歧南西斜坡隐蔽油气藏储层预测两项实际工作中,取得了良好效果,表明可视化解释技术在石油勘探中具有广阔的应用前景,是提高勘探效率和勘探成功率的有效技术手段。
Three-dimensional visual interpretation technology is a new seismic interpretation technology, which is different from the traditional seismic data interpretation. It is based on the three-dimensional visualization display, using the geological body or the three-dimensional research block as the unit, using the point, line, surface and Body - bound visualization of data volume. The technique combined with coherent body technology can be used to interpret and combine complex faults. The application of space-domain horizon automatic tracking technology can accurately implement the structural morphology. Using the target sculpture technology, the spatial distribution of the three-dimensional perspective lithologic body can be achieved by using the inversion data body And thickness trends. This technique has been applied to the interpretation of the complex fault block structure in Guanxi area of Dagang Oilfield and the prediction of subtle reservoirs in subsidence of southern Qilan slope. The good results have been obtained, indicating that visual interpretation technology has broad application prospects in petroleum exploration. Is to improve exploration efficiency and exploration success rate of effective technical means.
