浅谈中国海上地震勘探新技术应用
|
摘要
随着油气勘探程度的提高,勘探目标日益复杂,勘探难度越来越大,常规勘探技术往往难以解决出现的复杂勘探问题,因此研究并应用地震采集新技术具有重大的现实意义。文章重点介绍了国内近年来海上长缆大震源采集技术、立体震源技术、上-下缆采集技术以及海底电缆采集技术的应用进展情况及其取得的勘探效果,并简要分析了未来地震勘探采集技术的发展趋势。海上地震勘探新技术对于解决中深层勘探、复杂构造的成像具有明显优势。结合特定的勘探地质目标,不断总结经验进行应用创新是提高海上勘探技术水平的有效方法。
With the improvement of oil and gas exploration development , exploration targets become more complex and difficult.So common exploration techniques are often difficult to solve the complex problems.The research and application of new seismic acquisition technology has great practical value.This paper mainly introduces application progress and exploration effects of four new seismic technologies in recent year such as acquisition technologies for large or stereo source with long cable , upper-lower cable and submarine cable.Meanwhile , it also simply analyses its future development trend.New technology of offshore seismic exploration has advantages in mid-deep exploration and complex structure imaging.Combined with specific geological targets , carrying out application innovation is the effective method for improving offshore exploration techniques.
