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。 -
Comprehensive analysis shows that, the primary wave travel - time under the satisfactory first interface and the secondary interface with slot is always longer than that under the first interface with slot, but is shorter than that of the formation wave, while the primary wave amplitude under the secondary interface with slot is smaller than that under the first interface with slot, but is larger than that under fully cementing condition
分析結果表明，第一界面膠結良好，而第二界面竄槽的初至波到時總是延遲于第一界面竄槽的初至波，但卻比地層波早，其幅度明顯小於第一界面竄槽的初至波，但比全膠結的幅度大。 -
