This essay adopts the neural network and some parameters regression analysis to set up the some logging parameters prediction model of the rock drillability , then gets the continuous drillability classification value of single well formation . and deduces the theoretic relation of the formation pore pressure and the rock drillability creatively 本文采用神經(jīng)網(wǎng)絡(luò)法與多元回歸分析法建立了巖石可鉆性測井多參數(shù)預(yù)測模型及單井地層的連續(xù)可鉆性級值剖面,同時創(chuàng)造性地推導(dǎo)了地層孔隙壓力與巖石可鉆性之間的理論關(guān)系。
4 . the relationship of four properties : lithology , electrical property , physical property and oil bearing property was determined through the reinterpretation of logging data . logging parameter interpretation model and judgment criteria of oil , water and gas layers were formed , thus improved the precision of logging interpretation 4 .通過測井資料的二次解釋評價,確定了新齊14井區(qū)“巖性、電性、物性、含油性”之間的關(guān)系,建立了測井參數(shù)解釋模型及新齊14井區(qū)油氣水層判別標(biāo)準(zhǔn),提高了測井解釋精度。
" utilization of multi - attribute transformation in predicting well logging parameter " has transcended many traditional methods of reservoir research in many aspects , and possessing many outstanding technology superiority , which are showed below : ( 1 ) it takes new technology thought - " date - driven law " as the guidance , and inherits and synthesizes forefathers successful technology formed in many years . ( 2 ) ' it directly calculates the well logging parameter by way of the multiple attribute transformation , rather than by way of the sound impedance , like the porosity , while the way before is to make further estimates of the sound impedance from the seismic inversion result so that the result suffers the influence of many factors . ( 3 ) the usefulness of the seismic attribute is drawn from the seismic data , rather than the traditional poststack seismic data after nonlinear a transformation “ ;利用多屬性變換預(yù)測測井參數(shù)”在很多方面超出了傳統(tǒng)意義上的儲層研究方法,具有突出的技術(shù)優(yōu)勢,表現(xiàn)在: ( 1 )它以新的技術(shù)思想? ? “數(shù)據(jù)驅(qū)動法”為指導(dǎo),繼承并綜合利用了前人多年來形成的成功技術(shù): ( 2 )它是直接通過多屬性變換預(yù)測測井參數(shù),而不是通過聲波阻抗,如空隙度,以往的做法是從地震反演結(jié)果中的聲波阻抗做進(jìn)一步的模擬估算,其結(jié)果受到諸多因素的影響; ( 3 )所用到地震屬性是從地震數(shù)據(jù)中提取的,而不是傳統(tǒng)的迭后地震數(shù)據(jù)本身。
After evaluated the cap layers of this well field quantitatively by different kinds of logging parameters and evaluation methods , it is founded that by introducing the analyses viewpoint and technology of reservoir - seal combination into logging interpretation , oil / gas layers and water layers can be distinguished exactly . this approach is very useful in searching of exploitability hydrocarbon - bearing reservoir 利用各種測井參數(shù)和評判方法對研究井區(qū)的蓋層進(jìn)行了定量評價,發(fā)現(xiàn)在測井解釋中引入儲蓋組合分析觀點與技術(shù),能正確劃分油、氣、水層,有利于尋找有開發(fā)價值的油氣藏。
