second interface meaning in English

第二层间面

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
摘要为了研究油基钻井液性能和固井质量之间的直接关系，采用新建立的评价方法人工岩心法，考察了油基钻井液体系及其主要组分对固井作业中第一、第二界面剪切胶结强度的影响规律，以及不同混浆比例下对水泥浆胶凝强度、初凝时间、终凝时间和水泥石抗压强度的影响规律。
