滩浅海复杂过渡带SPS整理方法及软件研发

SPS Processing Method and Software Development for Complex Transition Zone in the Beach and Shallow Sea Area

近年来,滩浅海复杂过渡带海底电缆(OBC)双检检波器及二次定位技术的应用极大地改善了地震资料品质,同时也带来了OBC双检的两道地震信息以及同一检波点多套测量成果如何在地震勘探辅助数据(SPS)文件中表达的问题。常规SPS整理方法未给出多道地震信息的表达方式,而且采用常规SPS整理方法整理多套测量成果相当复杂,数据量大、效率低、错误率高,为此针对滩浅海复杂过渡带OBC双检与二次定位的情况,提出了一种新的SPS整理方法,即扩展OBC双检SPS关系文件以及重新定义检波点索引,并相应研发了滩浅海SPS整理软件。最后该方法在胜利油田ZH三维勘探项目中取得了较好的效果,证明了其正确性与实用性。

Recently,the applications of the OBC Dual-Geophone and secondary-positioning technology in the beach and shallow sea have improved the quality of the seismic data and it also brings two seismic information of OBC double check and the problem of how to express the multiple sets of surveying results in the same detection point in the auxiliary data（SPS）document of seismic exploration.The traditional SPS processing method couldn′t supply the expression of different tracks information and will be complicated in processing the measurements,such as large amount of data,low efficiency and high error rate.Therefore,aiming at the situation of OBC double detection and secondary location in the complex transitional zone of beach and shallow sea,this paper proposes a new SPS processing meth-od,which is to extend the OBC double SPS relation file and redefine the index of detection point,and to develop the SPS processing software of beach shallow sea.Finally,the method has achieved good results in the ZH 3 D exploration project in Shengli oilfield,and proved its correctness and practicability.
