江陵凹陷长江水域地震采集激发技术研究
|
摘要
以往在长江水域地区进行地震勘探时,无法在长江水域正常设计炸药震源激发,导致了较大的资料缺口。近几年来,随着海洋空气枪地震激发技术的应用和发展,在长江流域逐渐采用空气枪激发弥补了以往资料缺口的不足。本文结合近几年长江水域资料采集施工经验,深入分析空气枪施工参数,旨在进一步优化空气枪施工参数以克服复杂地表的影响,取全地震资料,弥补长江水域地区资料空白,使该区三维资料能够连片,有利于实现江陵凹陷油气勘探新突破。
In recent years,the application and development of marine-airgun-based seismic shooting technique has gradually solved the problem of former data insufficiency in Yangtze River where explosive source shooting cannot be used.Combined with the experience of data acquisition in Yangtze River,the author studies operation parameter of the airgun with the purpose of further improving its parameter to overcome complex surficial impact and acquire complete seismic data which can make up a continuous three-dimensional data in the area,favorable for new breakthrough of oil-gas exploration in Jiangling Sag.
