三维地震数据空间解释方法

A method for 3D seismic data space interpretation

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,这种方法已逐渐不能满足解释的需要。根据目前的技术现状,将常规的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,初步总结出从层位标定、骨架剖面建立、构造解释、数据拾取、网格、平滑、时深转换、成图等较完整的一套三维资料空间解释方法。与常规方法比较,该方法具有高效、直观、可检查的特点。在滨东、宁海等地区的试解释中取得了较好的应用效果。

For a long time we have been using a method for 2D seismic data interpretation to interpret 3D seismic data,which results in uncompletely and uneffectively full play to 3D seismic data. With progressively fining exploration tar-gets the method can't satisfy the requirement. Combining conventional section with special 3D slice data, taking biggrid section as a frame, using horizontal slice to interpret finely structures, we initially conclude a process for 3D dataspace interpretation that is a method including horizon calibration, hake section building, structure interpretation datapick, gridding, smoothing, time depth conversion and drawing. The method is higher effective, intuition and checkablecompared with conventional methods, which has got better effect in testing interpretation of Bindong, Linghai and etc.areas.
