塔里木盆地山地地震勘探技术

为了探明复杂盆地边缘山前带和山地的油气资源,对于地球物理勘探而言,需要具备非地震勘探技术、地震采集技术、静校正技术、噪声压制技术和构造成像技术等。其中基于非地震的盆地断裂系统认识和有利区带划分、基于卫星照片、大比例地形图,并考虑地下复杂构造的山地地震采集设计;以及采集涉及到的激发、接收诸因素的解决方案BGP(石油地球物理勘探局)均具自己的特色。通过研究使静校正技术、噪声压制技术,以及构造成像技术等具有较好的针对性、系统性、适应性。本文将通过近几年BGP在库车山地地震勘探的实例介绍BGP的山地地震勘探能力和技术。

Mountainous Seismic Exploration Technology of Tarim

To prove the oil and gas resources of marginal foothill belt and mountainous area of the complicated basin, it is necessary for geophysical exploration to be possessed of non-seismic exploration technology, seismic acquisition technology, static correction technology, noise suppression technology and structural imaging technology. Bureau of Geophysical Prospecting (BGP) has developed its own characteristics for the basin fault system identification and division of favorable zones based on non-seismic technology, satellite-based photos, landform maps with large scales, mountainous seismic acquisition design with consideration of underground complicated structures and acquisition technology including shooting and reception techniques. The research has enabled static correction technology, noise suppression technology and structural imaging technology to have good systematic suitability and adaptability. This paper briefs about BGP's mountainous seismic exploration capability and technology through some practical cases in which BGP has conducted mountainous seismic exploration in Kuqa area in the recent years.
