也门71区地震资料采集方法
|
摘要
也门71区地表地质条件异常复杂,特殊的地震地质条件,给地震采集带来施工和技术上的难题。通过分析工区地震地质条件、地质任务、以往资料质量等因素,对71区地震资料采集方法进行研究,以2006年二维地震采集项目为例,说明采用混合震源采集、弯直线施工、观测系统、激发因素等措施,取得较好的结果。
Surface geological conditions are very complex in Block 71 of Yemen.The special seismic condition of this area has brought about technical difficulties in construction.In this paper,the author investigated the method of seismic data acquisition in Block 71 through analyzing geophysical conditions and tasks as well as data available and,exemplified by the project of 2D seismic data acquisition in 2006,demonstrated that the adoption of such measures as mixed sources,crooked and linear lines,observation system and excitation parameters could improve the data quality.
