摘　　要：随着对沙漠区勘探的深入及认识的加深,采集方法也不断的改进,资料的品质也越来越高,可是始终困惑的难题是静校正问题。目前静校正方法多种多样,不论采用何种静校正方法,必须求取准确的低降速带资料。文章以准噶尔盆地中部1区块为例,重点介绍了在准噶尔盆地进行攻关试验并取得较好效果的大折射和微VSP。同时还探讨了在沙漠区低降速带调查的控制点分布情况。With the exploration and understanding of desert area, the acquisition technique is also gradually improved and the quality of data is advanced,but statistic correction always puzzled us. Now there are many ways to solve the problem of static correction, but whichever method we adopt we must try to get the exact data of the low-drop speed strap. Giving an example of the ZHUNGEER basin, this article introduces several universal techniques, for instance,little Refraction、Microseismogram log and Double-well Microseismogram log. It emphasizes the big refraction and micro-VSP which are examined and already got preferable resuit in the ZHUNGEER basin. At the same time, the paper discusses the distributing status of reference point of low-drop speed strap in desert area.
