准噶尔盆地永1井西三维野外资料采集跟踪处理质量控制方法应用
Quality Control of Field 3D Seismic Data Acquisition in West Well Yong-1 area of the Junggar Basin
【摘要】 针对不同的勘探要求和地表条件,相对应的野外采集方法也不同。本文以准噶尔盆地水1井西三维跟踪处理为例,阐述复杂地表特别是沙漠地区的野外资料采集质量的跟踪处理分析检验方法,如炮检点检查、野外静校正量检查、覆盖次数检查、振幅分析、信噪比分析、子波均匀性分析、干扰波类型分析、频率扫描分析等方法,应用在该区块三维的采集质量控制上,对原始资料进行采集质量分析,也为后续处理提供可靠的依据。
【Abstract】 Complicated surface shows different character in different exploration area, and different field data acquisition methods must be applied. Taking the 3D seismic follow-up processing in west well Yong-1 area of Junggar basin as an example, the method for analysis and test of quality field data acquisition in complex surface, especially in desert area, was explained. Those include check of shot points, field static correction, inspection of overlapping number, amplitude analysis, wavelet homogeneity analysis, and analysis of the disturbing wave types and the frequency sweeping. When they are applied to the quality control of 3D seismic data acquisition, not only the quality of data is insured, but also the future processing of data is improved.
