多波地震技术在中国部分气田的应用和进展
|
摘要
多波地震技术可同时采集地下地质体反射的纵、横波信息,通过处理提取反射纵、横波各项物性参数,并利用其在不同地质体中的反射特征差异,进行综合对比和解释,以预测储层的横向变化和含油气性。自2002年以来,中国石油天然气集团公司在鄂尔多斯苏里格气田、四川广安气田、柴达木三湖地区、松辽徐深气田开展了二维、三维多波地震勘探试验,积累了宝贵经验。本文在此基础上结合近年来国外多波地震勘探技术的发展,分析了当前国内多波地震勘探应用中仍然存在的问题,提出了加速推进国内多波地震技术应用的设想。
Multi-wave seismic technology can simultaneously acquire P-and S-waves information reflected from underground geologic bodies and carry out integrative correlation and interpretation by picking up various physical parameters of reflected P-and S-waves and using difference of reflection feature in different geologic bodies in order to predict lateral variation of reservoir and oil/gas-bearing ability.Since 2002 year,PetroChina system has carried out 2D3C and 3D3C experiments in Sulige Gas-field of Ordos Basin,Guang'an Gas-field of Sichuan,Sanhu Area of Qaidam Basin and Xushen Gas-field of Songliao Basin successively,gaining valuable experiences.On that basis and in combination with development of multi-wave seismic exploration technology abroad in recent years,the paper analyzed the issues still existed in current application of multi-wave seismic exploration technology at home,presented the ideas promoting application of multi-wave seismic technology at home.
