摘要
加速重锤型震源在常规地震勘探应用中,由于其激发能量、与记录仪器联机、DGPS实时监控等因素的制约,近些年鲜有地震勘探中成功应用的范例.在东方公司承担的乌干达三维高密度勘探项目中,重锤型震源成功应用于环境敏感区域的数据采集,取得了合格的地震资料.本文从重锤机械结构、工作原理、时序分布、生产组织、资料品质等几个方面,系统地论述了加速型重锤震源的技术要点及应用效果.
In conventional seismic acquisition domain,very few applications used Accelerated Weight Drop(AWD)seismic source were conducted in recent years due to low energy level,connection problem with acquisition instrument and DGPS signal real time monitoring,etc.Accelerated Weight Drops were successful applied in sensitive operational area and received qualified seismic data in the high density seismic program which carried out by BGP in Uganda.Key technical points and applications of Accelerated Weight Drop are analyzed& discussed systematically in this paper from the aspects of configurations,working principle,time sequence,organization,data quality,etc.
