非零偏时延VSP资料处理关键技术
Key technologies of non-zero offset time-delay VSP data processing
摘要
Abstract
Since non-zero-offset time-lapse vertical seismic profiling(VSP)data contain abundant near-well wave field information,the VSP reflection information and seismic attributes can be applied to effectively monitor the migration of injected fluids near wells,boas-ting a broad application prospect.Due to the limitation of observation methods,non-zero-offset time-lapse VSP data exhibit limited su-perposition times,thus demanding more stringent processing for two-phase VSP data.By introducing the repeatability analysis and con-sistency processing method of two-phase data into the conventional processing technology for non-zero-offset VSP data,this study devel-oped a processing technology flow for non-zero offset time-lapse VSP data.Moreover,this study conducted analysis and tests of the meth-ods for processing the intra-shot consistency of time-lapse data and the consistency of two-phase data.As verified by the application in well A,the processing flow and key technology for non-zero-offset time-lapse VSP data proposed in this study enjoy high operability and practicability and,thus,have the potential for wide applications.关键词
