转换波地震资料处理方法研究

Study on Processing Method for Seismic Data of Converted Wave

转换波勘探是一门正在兴起的物探技术。随着国内外研究的不断深入,转换波勘探技术日趋成熟,很多地区都取得了较好的应用效果。吐哈油田分公司根据转换波勘探的特点和优势,选择了在转换波勘探最有利的红台-小草湖地区进行了转换波野外采集,综合利用纵、横波地震信息对该区域进行储层预测和油气检验。对转换波产生原理、转换波野外采集、转换波主要处理技术等方面进行了重点研究,进行了吐哈盆地红台地区二维转换波地震资料实际处理,为吐哈盆地综合利用纵、横波地震信息进行油气勘探奠定了坚实的基础。

The seismic exploration of the converted wave is a new technique of geophysical prospecting, with study inside and outside our country going deep on, it is increasing mature and has taken good effect in many areas. According to the characteristics and advantage of the converted wave, Tuha oilfleld Company selected the most favorable area, Hoagtai - Xiao Caohu for converted wave exploration to carry out field acquisition of converted wave, and synthetically use seismic information on P - wave and S - wave to predict reservoir and test oil and gas in the area. Creation principle of converted wave and field acquisition of converted wave and main processing technique of converted wave are predominately studied. Actual seismic data processing of 2 - D converted wave in Hongtai area in Tuba basin was carried out, which provides solid foundation for Tuha basin to synthetically use seismic information on P -wave and S -wave to off and gas exploration.
