摘要: 通过多年持续攻关,塔里木盆地山地地震采集技术取得了长足进展,但仍有许多勘探难题需进一步解决。阐
述了针对高大山体区地震资料的低信噪比问题和高陡复杂构造成像问题而提出的一种攻关采集方法。该方法以宽线
采集技术为基础,在增强压噪能力、提高静校正精度、改善陡倾角地层成像效果等方面采取了针对性技术措施。这些
技术措施的的应用大幅度改善了地震剖面的成像质量。

Abstract: Though considerable progress on the seismic acquisition technology of mountainous areas in Tarim Basin has been
made through years of research,there are still many exploration problems need to be solved. In this paper,a method of seismic
acquisition is presented for solving the problems of low S/N ratio and poor high-dip complex structure imaging in mountainous
areas. Pertinent technical measures are adopted to enhance ability of attenuating noise,and to improve accuracy of static
correction and imaging of high-dip structure. Through application of these technical measures,imaging quality of seismic
section has been improved significantly.

Key words: complex mountainous areas, low S/N, high-dip structure, seismic acquisition, geometry, high-density wide line
