哈山地区地震勘探采集技术研究
|
摘要
哈山地区位于准噶尔盆地北缘、什托洛盖盆地和准噶尔盆地结合部,乌夏断阶带和哈山构造上,该地区表层岩性变化快,深层逆冲推覆构造发育。地震勘探难点表现为表层结构复杂,激发、接收条件差,深层资料信噪比低,成像困难。针对这些问题,在哈山地区采用小面元、高覆盖的观测系统,同时针对浅层进行加密炮排,提高浅层覆盖次数。通过一些技术的应用,新采集的资料品质较老资料有了大幅度的提高。最后根据实际资料分析,提出该地区下一步的采集建议。
Hashan area is located in the Department of the northern margin of the Junggar basin and Heshituoluogai basin,and in Wuxia fault belt structure in the region.The subsurface lithology changes fast,and deep thrust structures are developed,so the difficulty is very serious in exploration for surface structure complex,shooting and receiving condition difference,deep low S/R data,and the imaging processing.In view of these problems,is proposed that small bin,high fold of the observation system,and shallow layer of densification to improve the shallow folds.Through a number of techniques application,the new acquisition data quality has been greatly improved than the old data.Finally according to the actual data analysis,it is put forward that this area to the next gathering opinions.
