Comprehensive well and geological constrained seismic inversion - comprehensive constrained inversion ( cci ) , is based on nonlinear inversion techniques . it makes full use of detailed vertical resolution of well data and horizontal dense sampling of seismic data . according to geological theory , it inverts lithological profile in multi - wells and complex geological condition . . at present , there are no perfect mathematical methods to solve nonlinear equations 地震資料與測井資料的綜合約束反演是在非線性反演的基礎(chǔ)上,充分利用測井資料詳細的垂直分辨能力和地震資料地面上采樣點密集均勻分布的特點,把這兩種資料結(jié)合起來,取長補短,以地質(zhì)理論為依據(jù),針對多井及構(gòu)造復(fù)雜的地質(zhì)條件,反演出井以外的巖性剖面。
Experimental result and practice shows it is possible using seismic information forecasting subtle trap . integrated using geology % log , drilling data , specia ! seismic processing technique - , interpretation technique , including high precision horizon calibration technique , 3d seismic visualizing interpretation , seismic coherence analyze , attribute analyze , logging - constrained inversion , time frequency analyze , ann forecasting technique , subtle trap object is identified and interpreted . finally , advantage object of subtle trap in this area is determined 綜合地質(zhì)、測井和鉆井資料,依靠先進的地震特殊處理和解釋新技術(shù),包括高精度的層位標(biāo)定技術(shù)、三維可視化解釋技術(shù)、地震相干技術(shù)、屬性分析技術(shù)、測井約束反演技術(shù)、時頻分析技術(shù)、多參數(shù)油藏檢測技術(shù)和神經(jīng)網(wǎng)絡(luò)預(yù)測等技術(shù),對隱蔽油氣藏目標(biāo)進行識別、解釋和成藏研究,最后指出工區(qū)內(nèi)隱蔽油氣藏的有利目標(biāo)。
