The.anti-corre.ation me.hod for re.oving harmonic distortion in vibrose.s slip-swe.p data

引用

Applie. Ge.physics 2012年第2期9卷 159-167,234页

作者：张红静周辉 abd e.-Aziz Khairy abd e.-aal 张洁油气资源与探测国家重点实验室 CNPC物探重点实验室中国石油大学(北京) National Re.e.rch Institute.of Astronomy and Ge.physics(NRIAG) Department of SeismologyHelwan11722 CairoEgypt 中国石化石油物探技术研究院

The.slip-swe.p te.hnique.is one.of the.high-e.ficie.cy, high-fide.ity, and e.vironme.tal vibrose.s se.smic prospe.ting te.hnique. which consists of a vibrator group swe.ping without waiting for the.pre.ious group＇s swe.p to te.minate. The.cycle.time.can be.re.uce. drastically and he.ce.the.production e.ficie.cy can be.incre.se. significantly but harmonic distortion of one.swe.p will le.k into the.re.ord of the.othe. swe.p. In this pape., we.propose.an anti-corre.ation me.hod for re.oving harmonic distortion in vibrose.s data. This me.hod is base. on de.omposition of the.ground force.signal into fundame.tal and harmonic compone.ts. The. the.corre.ponding anti-corre.ation ope.ator can be.compute. to e.timate.the.e.e.gy of e.ch harmonic afte. corre.ating the.vibrose.s data with the.corre.ponding harmonic compone.t. Finally, the.vibrose.s harmonic noise.to be.re.ove. can be.obtaine. by subtracting the.e.tracte. harmonic noise.from the.trace. of the.pre.ious group＇s swe.p. The.advantage.of the.propose. me.hod is that it can proce.s both uncorre.ate. and corre.ate. vibrose.s se.smic data. More.ve., the.algorithm is simple. stable. and computationally fast. e.pe.ially, the.significant contribution of this me.hod is a conside.able.re.uction in the.harmonic without any alte.ation of the.de.ire. signals. The.me.hod was te.te. on both synthe.ic and fie.d data se.s to validate.the.good harmonic noise.suppre.sion re.ults.
