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。 -
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
摘要從理論正演數值模擬、刻度井試驗資料和實際生產井時間推移測井資料3個方面，探索用變密度（ vdl ）波形評價第二界面膠結質量的方法，提取反映第二界面的膠結狀況的特徵量。
