一种三维地震数据空间解释方法

长期以来，三维地震勘探资料的解释一直沿用二维的方法和流程，不能完全、有效地发挥其应有的作用。随着勘探目标的进一步细化，这种方法已不能满足解释的需要。根据目前解释技术的现状，将常规剖面与三维所特有的切片资料紧密结合，以大网格的剖面为格架，用水平切片精细解释构造。初步总结出层位标定、骨架剖面建立、构造解释、数据拾取、网格化、平滑、时深转换、成图等一套较完整的三维资料解释方法，与常规方法比较，具有高效、直观、可检查的特点。该技术在滨东和宁海等地区进行了试验并取得了良好的效果。

A method for 3-D seismic dada space interpretation

For a long time we have been using methods for 2-D seismic data interpretation to perform 3-D seismic data interpretation, which fails to take full advantages of 3-D seismic data. This approach is no longer satisfying the requirements of data interpretation as exploration targets are getting more complicated and more specific. Combining conventional section with seismic slices, we presented a space 3-D seismic data interpretation method. This method uses large grid size sections as a frame, and realizes fine structure interpretation using horizontal slices. It consists of horizon calibration, framework section selection, structural interpretation, data picking, gridding, smoothing, time-depth conversion, and drawing. Compared with conventional methods, the proposed method is effective, intuitional, and checkable. Satisfactory results have been reached in interpretation of data from areas such as Bindong and Linhai.
