  1. In order to study the direct relation between oil - base drilling fluid performance and cement job quality, a new developed evaluation method ( artificial core method ) was adopted ; the effects of the oil - base drilling fluid system and its main components on the shear cementing strengths of the first and second interfaces in cementing operation were investigated ; and those of the different mix slurry ratios on the gel strength, initial set time, final set time of slurry and the compressive strength of bond cement were examined too

    摘要為了研究油基鉆井液性能和固井質量之間的直接關系,採用新建立的評價方法人工巖心法,考察了油基鉆井液體系及其主要組分對固井作業中第一、第二界面剪切膠結強度的影響規律,以及不同混漿比例下對水泥漿膠凝強度、初凝時間、終凝時間和水泥石抗壓強度的影響規律。
  2. Based on the approach of turning some of the relevant extreme - value - type and logarithmic normal distribution variables into independent and normal random variables, the shear - slipping failure probability of a high arch dam is worked out to be of the order of magnitude of 10 ^ ( - 5 ) by means of second - order moment method

    在將部分相關的極值型與對數正態分佈隨機變量轉換為獨立、正態隨機變量的基礎上,利用二階矩法計算得到某高拱壩的剪滑失效概率為10 ^ ( - 5 )量級。
