The velocity , density and especially the anisotropic parameter which is important to the study of fractured formation can be achieved by the generalized linear inversion based on the ava inversion equations 用此反演方程對(duì)ti介質(zhì)進(jìn)行多波ava參數(shù)反演,不但可以求出地層速度及密度,還能得到各向異性系數(shù),該參數(shù)對(duì)裂隙型地層研究具有重要意義。
In this paper , taking the measured error sound velocity profile as the initial guess value , the sound beam travel times and beam angle recorded by the multi - beam system and the generalized linear inversion method are used to get a sound velocity profile close to the actual sound velocity profile , and the inversed sound velocity profiles have contributed to the reduction of sound velocity profile error 摘要以測得的誤差聲速剖面作為初始猜測值,利用多波束記錄到的波束傳播時(shí)間和波束角等信息,通過廣義線性反演得到一個(gè)與實(shí)際聲速剖面比較接近的聲速剖面,這有助于減少聲速剖面的誤差。
In this paper , author consider the combination of theory with practice especially . in the process of study , the avo method technology and technology of seismic data process and the study of interpretation were combined . on the basis of extensive absorbing the advance technology inside and outside , the theory of generalized linear inversion avo and non - linear avo inversion and weighted stacking technology were discussed detailed to the characteristic of heterogeneous reservoir . then , the forward and inversion of those methods were performed 在本文的研究中, avo方法技術(shù)與地震資料處理及解釋研究得到了緊密地結(jié)合,在廣泛吸取國內(nèi)外avo油氣檢測先進(jìn)技術(shù)的基礎(chǔ)上,針對(duì)非均質(zhì)氣藏特點(diǎn)的需要,文章詳細(xì)論述了廣義線性avo反演方法和非線性avo反演方法、 avo反演中的加權(quán)疊加技術(shù)的方法原理,并對(duì)上述方法分別進(jìn)行了詳細(xì)的模型的正演和反演的研究。
On the basis of displacement - time series of the slope , a nonlinear dynamic model is set up according to backus generalized linear inversion theory in this paper . due to the equivalence beween autonomous gradient system and catastrophe model , a standard cusp catastrophe model can be obtained through variable substitution . the method is used in analysis of displacement data of huangci landslide and wolongsi landslide and in understanding how slopes evolve before sliding . the result shows that the nonlinear dynamic model can make satisfactory prediction result . is it most important that there is a sudden fall of d , which indicates the occurrence of catastrophe ( when d = 0 ) 研究表明,滑坡變形失穩(wěn)過程具有混沌和分維特性,可以用分形理論來研究滑坡預(yù)測問題,基于對(duì)任一連續(xù)函數(shù),至少在較小的鄰域內(nèi)可以用多項(xiàng)式任意逼近的數(shù)學(xué)理論,運(yùn)用改進(jìn)的backus廣義線性反演理論,以斜坡位移時(shí)間序列為基礎(chǔ),反演了斜坡演化的非線性動(dòng)力學(xué)模型。并利用自治梯度系統(tǒng)與突變模型的等價(jià)性,通過變量代換得到標(biāo)準(zhǔn)的尖點(diǎn)突變模型。
