缅甸火山岛弧带地震采集方法研究
|
摘要
缅甸火山岛弧带具有独特的构造和沉积特征,是近年来的勘探热点。这种构造样式的多样性决定了油气藏的复杂性,随着勘探工作的深入和资料的复杂化,优化采集方法变得越来越迫切,严重困扰了地震采集工作的开展。为了大幅度地提高该区的地震资料成像精度,满足精细油气藏勘探的需求,针对缅甸火山岛弧带的复杂勘探难点,开展了大量的采集方法攻关研究,形成了预测性的表层调查技术、分季施工技术、综合静校正技术和宽线采集技术。通过上述技术在该地区的应用,地震资料的成像效果明显提高,取得了良好的勘探效果。
The arc zone of volcanic island in Myanmar had a unique tectonic and sedimentary features,it has been the highlight for exploration in recent years.The diversity of structure styles determined the complexity of reservoirs.With deepening of exploration and complication of data,the optimization of acquisition methods became more and more urgent,it seriously troubled the seismic acquisition.In order to greatly improve the precision of data imaging in the seismic exploration area,meet the needs of fine reservoir exploration,research and development are carried out on the seismic acquisition in consideration of the problem exploration in the arc zone,the forecasted surface survey technology,acquisition technology in different seasons,integrated static correction technology and wide line acquisition technology are established.After the application of these technologies in the area,data imaging result is improved and good effect of exploration is obtained.
