摘要
准噶尔盆地二叠系是近几年新疆油田的重点油气勘探区域。由于受多次波的影响,二叠系内幕成像效果差,剖面上地层接触关系紊乱,严重制约该层系的油气勘探进程。由于陆地层间多次波的复杂性,很难通过单一的方法达到理想的压制效果。为此,立足多次波形成机理,利用VSP资料准确地识别了多次波,并应用GeoEast基于数据驱动的层间多次波压制方法,较好地解决了准噶尔盆地层间多次波对勘探主力目的层二叠系地震成像质量的影响。
The Permian of the Junggar Basin has been a key oil and gas exploration area for Xinjiang Oilfield in recent years.Because of the multiples,the imaging and stratigraphic contact relationships of the Permian interior are disorderly and consequently,which severely restrict the process of oil and gas exploration in the strata.Due to the complexity of land internal multiples,the desired suppression effect is difficult to achieve by a single method.Relying on the formation mechanism of multiples,this paper accurately identifies multiples with vertical seismic profile(VSP)data and well eliminates the influence of the internal multiples on the seismic imaging quality of the Permian,i.e.,the main exploration target layer,in the Junggar Basin by applying the data-driven suppression method for internal multiples in GeoEast.
