摘要
浊积岩油气藏具有分布广、埋藏深、隐蔽性强等特点,常规勘探技术往往难以有效识别。针对上述问题该文在小波分频成像、构造约束保边滤波、井控提高分辨率等地球物理处理技术的基础上,通过运用有色反演、地层倾角、方位角与相干分析等技术来描述浊积体的空间几何形态,开展对浊积岩油气藏有效勘探方法的研究,并有效指导浊积岩体隐蔽油气藏勘探工作,总结出一套适合辽东湾探区浊积体识别的地球物理技术流程,对指导该区的岩性油气藏勘探具有一定的推广价值。
The turbidite reservoir is characterized by wide distribution, deep burial and strong concealment, so it is difficult to identify the turbidite reservoir by conventional exploration technology. The wavelet frequency-dependent imaging, structure-oriented edge-preserving smoothing and well control for resolution improvement combined with geophysical processing techniques such as color inversion, dip, azimuth and coherent analysis were used to describe the geometrical features of turhidite. In addition, the new geophysical identification technologies for Paleogene turbidite were applied properly for Liaodong Bay area. The field study confirms that the new techniologies lay a good foundation for stratigraphic-lithologic reservoir in this area.
