【摘要】 地震道积分是一项利用转换的相对速度剖面而进行地震分析的技术 ,与GLOG技术利用波阻抗剖面分析地层效果大致相近 ,但前者具有砂层标定方法简单、处理速度快、费用又省等优点。经过标定的道积分剖面 ,基本可以代替连井油藏剖面 ,应用起来方便、直观。作者曾用本方法在东海地区多口井中预测获得令人满意的效果 ,因此地震道积分技术是一项具有发展潜力、应用价值的好方法。更多还原

【Abstract】 Seismic channel integral is one of the seismic analysis technology of using transformed relevant velocity profile,it is similar to the GLOG technology which utilize the wave resistance profile to analysis the stratum but the former have the advantage of reflecting tiny changes in sandy stratum of the high velocity. The method of sand layer definition will be more simple and accurate. The processing velocity is gained at higher speed and costs cut by this method. After the layer definition, the profile could almost substitute that of joining drilling section with oil bearing. The authors of this paper have received the satisfactory effect using this method in East China Sea.更多还原
