摘要
本文针对山地Walk-away VSP资料采集、处理的特点,从优化采集参数、中高频静校正方法,速度模型建立及其合理性评价、波场分离、叠前偏移成像等几个方面进行了研究,建立了一套资料采集、处理方法。通过对LG2井的Walk-away VSP资料的采集、处理和解释,获得了高质量的井旁成像剖面,准确标定了储层的位置,落实了礁滩的形态及大小,精细刻画了礁体内部的细节,表明文中所使用的山地Walk-away VSP资料采集、处理、解释技术可行。
In view of data acquisition, and processing feature of mountainous Walk-away VSP and starting from following aspects: optimizing acquisition parameters, mid-to-high frequency static corrections, velocity model-building and reasonable approximation, wavefield separation and prestack migration imaging, the paper carried out study and created a set of data acquisition, processing methods. The paper also acquired high-quality imaging section around well, accurately calibrated the position of reservoir, trapped the configuration and size of bank reef and finely described interior detail in reef by acquisition, processing and interpretation of Walk-away VSP data in LC-2 well, showing the feasibility of data acquisition, processing and interpretation techniques of mountainous Walk-away VSP used in the paper.
