固井水泥环内部的各种缺陷会导致层间窜流、井口带压等事故。无损检测技术作为一种非破坏性的检测方法,可以对固井水泥环内部的缺陷进行检测。基于超声波在连续介质中的传播规律,采用COMSOL仿真软件模拟压电效应以及超声波在水泥环中的传播状态和反射规律,研究水泥环缺陷反射信号的相关特性。研究结果表明:选择1.0 MHz 5周期Hanning窗调制的超声正弦波作为激励信号,超声探头可以在50μs内接收到水泥环缺陷的反射信号;不同类型的缺陷中,矩形缺陷的检测效果最佳;当缺陷主方向与超声波入射方向垂直时,检测效果最佳。研究结果验证了超声波无损检测技术可以快速准确地确定固井水泥环内部缺陷的类型和位置,同时调整超声波入射角度有助于提升检测效果,可为超声波在水泥环内部缺陷检测中的应用提供一定的指导意义。

Dear editor,With the development of the Internet and digitalization,databases and data-analysis tools (for example, artificial intelligence and machine learning) have exhibited a significant potential to improve service quality. Data have become an invaluable asset, which is the basis of new datatraining models [1]. A conventional data-trading ecosystem comprises three parties: seller (data owner), buyer, and data-exchange platform (third party).

作者： WANG Suibao LI Tingting zhao yanqi Northeast Petroleum University

1 Introduction With the increasing demand and the lack of natural gas in China, the unconventional gas is urgently needed as the substitute of the conventional natural gas which is explored more difficult. Coal bed methane is the most possible substitute of the conventional natural gas for the reason that our country is rich in coal resource and CBM （CBM is short for coal bed methane） resource is very rich in China.

1 Introduction Seismic waveform reflects the basic information of seismic data which mainly includes seismic amplitude, phase, frequency etc. Zero-phase wavelet has high signal- to-noise ratio, high resolution and the characteristic of symmetry. But in the case of thin layer, the zero-phase reflection waves from top and bottom will interfere with each other and its symmetry is disappeared. The peak （trough） will no longer correspond to the interface.
