模型正演技术在准噶尔盆地东部地震解释中的应用
|
摘要
通过近几年在准噶尔盆地东部探区岩性目标的勘探实践,从4个方面强调了模型正演技术在地震资料解释过程中所发挥的关键作用:地震资料处理过程中的质量监控;地震波组对应的地质意义;侏罗系西山窑组煤下储集层识别的可行性判断;等时层序界面"穿时"的约束作用。应用效果显著,在岩性目标勘探实践中有借鉴意义。
By practices of lithologic targets prospecting in eastern Junggar basin,this paper highlights the key role of forward modeling technology in seismic data interpretation and processing from the following 4 aspects:(1)the quality monitoring in seismic data processing;(2)the corresponding geological meanings to the seismic reflection events;(3)the feasibility of identification for the reservoir covered by Xishanyao coal bed of the Jurassic;and(4)the restriction of diachroneity of the isochronic sequence interface.The results show that the effect of this method is remarkable in application in this area.
