摘要
DZ地区具有良好的储集条件,在该区进行高精度地震资料采集处理解释一体化勘探对寻找复杂隐蔽的油气藏及储层岩性预测有重要的意义。针对本区多变的地表地质条件和复杂的构造类型,在高精度采集的基础上进行高精度精细处理来提高地震资料空间和时间方向的分辨力、信噪比,提高速度场的准确度,进而提高小幅度构造叠加质量及偏移成像的精度。
DZ region has favorable reservoir conditions,it has important significance to carry on integration of high-precision seismic data acquisition,processing and interpretation tosearch for the complex,hidden hydrocarbon reservoir and reservoir lithology prediction in the area . Aiming at variable surface geological conditions and complex structure types,carrying on high precision fine seismic data processing basedon fine high precision acquisition to improve the resolving power of seismic data in space and time,signal to noise rati-o,the accuracy of the velocity field,thereby improving the superposition quality of small amplitude structures and migration imaging accuracy.
