( 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
「 ;利用多屬性變換預測測井參數」在很多方面超出了傳統意義上的儲層研究方法,具有突出的技術優勢,表現在: ( 1 )它以新的技術思想? ? 「數據驅動法」為指導,繼承並綜合利用了前人多年來形成的成功技術: ( 2 )它是直接通過多屬性變換預測測井參數,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果中的聲波阻抗做進一步的模擬估算,其結果受到諸多因素的影響; ( 3 )所用到地震屬性是從地震數據中提取的,而不是傳統的迭后地震數據本身。In addition, people who use livestock product and dairy on their diets are at very higher risk for certain health problems. these problems include mutation of dna structure of human body, human immunity deterioration, birth defects and cancer
