录井信息化是录井行业发展的一次重大机遇

录井信息化的重要性很多人予以关注,该文主要从录井信息化的提出、基本构成、建设总体思路等方面,探讨录井信息化的可能性,从录井信息化的作用上讨论了录井行业发展的机遇问题。

浅谈录井资料解释面向现场转移的必要性

该文就如何提升录井资料应用价值和时效性提出了自己的观点,针对老油田勘探开发对录井信息的需求,阐述了实现录井综合解释、评价现场化、及时性的意义及可行性,以实例阐明了录井信息化发展的趋势和录井资料解释评价与决策现场化的关系,这为把握录井服务的方向及技术发展趋势的确定提供了参考和思路。

加密技术在录井软件中的应用

计算机技术的高速发展极大地推动了录井信息化的发展,但各种各样的软件安全问题也不断突显出来。为避免录井应用软件被非法盗用,文章提出了一种基于硬件信息的软加密技术,采用MD5(Message-Digest Algorithm 5消息摘要算法第五版)和RC4(Alleged RC4)加密算法对获得的信息加密生成许可证,从而有效防止录井软件的非法复制和传播。实践证明,该方法加密强度高,能够很好地完成录井软件加密要求。

A novel method of photographic geological logging based on parallel image sequence in small tunnel

Small tunnels such as engineering geological exploratory tunnels and mine roadways are generally narrow, which make the existing photographic geological logging technique inapplicable. Therefore, geological logging of exploratory tunnels has always been taking the method of manual sketch work which has low efficiency and poor informatization degree of products, and it is a technical issue requiring urgent settlement for geological logging of small tunnels. This paper proposes and studies novel methods of photographic geological logging suitable for small tunnels, including image acquisition, image orientation control, image geometric correction, unfolded image map generation and geological attitude measurement, etc. Experiments show that the method can meet the precision requirement of geological logging. The novel method helps to realize the fast acquisition and processing of image-based geological logging data for small tunnels, and the forms of logging result are more abundant and more applicable to informatized management and application of geological logging data.
