第二界面 meaning in English
second contact surface
Examples
- Second contact surface
第二界面 - 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
分析结果表明，第一界面胶结良好，而第二界面窜槽的初至波到时总是延迟于第一界面窜槽的初至波，但却比地层波早，其幅度明显小于第一界面窜槽的初至波，但比全胶结的幅度大。 - Based on the theoretical numerical simulation , experimental data of calibration pits , and time - elapsing logging data in cased production pits , a study is made for searching an evaluation method for cementing quality of the secondary interface by variable density logging ( vdl ) , and the eigenvalue about the cementing quality of the secondary interface is obtained
摘要从理论正演数值模拟、刻度井试验资料和实际生产井时间推移测井资料3个方面，探索用变密度( vdl )波形评价第二界面胶结质量的方法，提取反映第二界面的胶结状况的特征量。 - 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。
