刻度井 meaning in English

calibration well

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。
