新疆大井南勘查区位于克拉麦里山南麓的戈壁荒漠平原区,区内遍布戈壁、冲沟、沙丘、盐碱地和沙漠等多种地形,表层地震地质条件十分复杂。导致单炮记录差异大、干扰严重、信噪比低。通过采用叠前去噪、振幅补偿及一致性处理、静校正等手段,较好地解决了复杂表层条件引起的单炮品质差异问题,使剖面动力学特征和运动学特征统一,保持了较好的波组特征,具有较高的分辨率,较有利于薄煤层及煤层结构解释。
The survey area of Dajing South in Xinjiang is located in the Gobi Desert Plain in the south of the Kalamailili Mountain. The area is covered by a variety of terrains such as Gobi, gully, sand dune, saline-alkali land and desert. The surface geological conditions are very complicated. Resulting in a single shot record differences, serious interference, low signal to noise ratio. By using prestack noise reduction, amplitude compensation and consistency processing, static correction and other means, the problem of single shot quality difference caused by complicated surface conditions can be solved well and the dynamic characteristics and kinematics characteristics of the section are unified and maintained well. Of the wave group characteristics, with higher resolution, more conducive to the thin seam and coal seam structure interpretation.
