【摘要】 本文针对套管井中第二界面定量评价的问题,首先开展了套管井中地层波的影响因素的研究,为定量评价第二界面的胶结质量奠定了基础;接着,通过有效确定地层波到达时间,以及地层波信号提取及能量计算,并在充分考虑地层岩性影响的基础上修订了传统的第二界面胶结指数公式,建立了一套完整的定量评价固井二界面胶结质量的新方法;最后通过实际资料处理与评价,证明所提出的定量评价固井二界面胶结质量方法取得了满意的效果。更多还原

【Abstract】 This paper carried through the study of influencing factors of the formation wave in cased hole at first,this study is basal work for quantitative evaluation of second interface cementing quality.At the following,the arrival time of the formation wave has been achieved by effective method,the formation wave signal has been distilled,and the energy of the formation wave is also been worked out.On the base of thinking about the lithology influence,the conventional bond index of second interface is emended in this paper,a suit of new method has been build about quantitative evaluation of second interface cementing quality.At last the validity of new method was been proved by the disposure and evaluation of actual data.更多还原
