A biparameter inversion system for a class of 1-D wave equation is established. The beck-ground of this work is the multi-parameter inversion in seismic date processing. Taking impulse func-tion as a focused seurce,a biparameter inversion method is presented. This method is based on the singu-larity analysis theory for hyperbolic equation. The posedness of this inverse problem is also discussed.

The gas bearing sand bodies in the Upper Paleozoic in Eerduosi Basin belong to the distributary channel deposits of lake delta plain,being of the properties of low porosity,low permeability and high impedance.In accordance with such a geological objective,4 categories(15 items)of the methods and techniques were developed and summarized,and the processing and interpretation technical series of the gas bearing sand body comprehensive prediction objectives in the Upper Paleozoic in Eerduosi Basin were set up.In the series,by taking the objective oriented large comprehensive database as the basis,the computer technique as the means,and the processing and interpretation techniques of seismic formation lithology as the core,the organic combination of multiple disciplines as geology,well logging and seismics and the processing interpretation integration under the same geological objective are realized.Under the guidance of AVO theory,on the basis of information theory a new logging constrained multi parameter inversion technique is proposed,which may avoid the lithologic interpretation errors caused by decrease of impedance of the gas bearing sandstone.The lithology of seismic high impedance formation can be effectively identified by use of AVO property response caused by different lithological Poisson ratios.Under the encouragement of practical drilling benefits,a step by step deep going property description is carried out for the objective sandstone reservoirs by use of a rolling mode processing interpretation method and other techniques.Through the examination of drilling,it is shown that the spacial distribution of the sandstone reservoirs with a thickness of about 10 meters can be precisely predicted by the technical series.The coincidence ratio of predicting the sand bodies is more than 70% and the drilling success ratio is up to 81.8%.

鄂尔多斯盆地上古生界含气砂岩体主要属湖相三角洲平原分流河道沉积,具低孔低渗和高阻抗特征。针对这一地质目标,研制和总结出4类15项方法技术,建立了鄂尔多斯盆地上古生界含气砂岩体综合预测目标处理解释技术系列。该系列以面向目标的大型综合数据库为基础,计算机技术为手段,地震地层岩性处理解释技术为核心,实现了地质、测井、地震等多学科的有机结合和同一地质目标下的处理解释一体化。在AVO理论指导下,以信息论为基础,提出了一种新的测井约束多参数反演技术,可克服砂岩含气阻抗值降低而造成的岩性解释陷阱;利用不同岩性泊松比差异所形成的AVO特征响应,可以有效区分地震高阻抗层的岩性;在实际钻探效益的驱动下,采用滚动式处理解释方法,应用各种新技术,对目标砂岩储集体实施逐步深化的特征描述。经钻探检验,该技术系列较准确地预测了厚10m左右砂岩储集体的空间展布形态,砂岩体预测符合率大于70%,钻探成功率达81.8%。

Seismic inversion is an important problem in theoretical and applied seismology. Because higher-dimensional wave equation inversion is much difficult to study in theory and practice,research on inversion for elastic parameters of stratified media attracts numerous mathematicians and geophysicists. So far single parameter inversion based on one dimensional acoustic equation has been solved well theoretically by previous researchers and recently is being applied in seismic exploration. But multi-parameter inversion based on vector wave equation with non-impulsive wavelet response need to be studied further
