摘　　要：测量工序精度是地震采集资料精度的基础,测量点位精度决定着后续资料处理的质量。通过对当前地震勘探分辨率所能达到精度以及地震采集过程中点位测量、放线、震源施工3个环节的介绍和施工精度分析,得出采用不同施工方式采集资料主要精度的限制因素以及对测量环节的精度要求。在实际生产应用中,根据所采用的施工方法合理选择测量点位的精度,对解放生产力、提高作业效率有一定借鉴意义,与目前行业内正在被普遍推广应用的可控震源高效采集相适用。The accuracy of measurement process is the basis of the accuracy of seismic acquisition data,and the accuracy of measure⁃ment points determines the accuracy of subsequent data processing.The main factors of limiting acquisition data precision under differ⁃ent construction methods and the accuracy requirements of measurement link are obtained through the analysis of current seismic ex⁃ploration resolution and the introduction and construction accurancy analysis of the point position measurement,setting out and seismic source construction in the seismic acquisition process.In the actual application,the accuracy requirement of the measurement point should be reasonably selected according to the adopted construction method to emancipate the productivity,which has a certain refer⁃ence significance to improving the operation efficiency,and is suitable for the high-efficiency acquisition of vibroseis which is widely used in this industry.
