逐级循环交互式测井曲线井间对比

Interactive Interwell Correlation with Vertical Regressive and Lateral Loop Control.

地层对比是多井评价、油气藏描述中不可缺少的部分。我们所开发的对比系统，在两口井之间的对比按由大到小、由粗略到精细的顺序逐步进行，多口井之间的对比采用了循环检测的控制方法。充分发挥人与计算机两者的优势，既能自动对比，也能在需要的时候交互式给定对比条件、交互式地修改对比结果并自动记录下修改的结果。本研究在自动对比方面的最大特点是使复杂的问题按简单明了的方式逐步进行并有效地解决了地层在横向上的相变问题，文中论述了方法原理与实现技术。给出了在ＳＵＮ工作站上完成的对比实例。

Formation correlation is indispensable for multiwell evaluation and reservoir characterization. In the correlation system mentioned in this paper, two wells correlation is conducted step by step from large trend to fine signatures of logging curves and loop closure is used for multiwell cyclic correlation. Correlation can be done automatically or interactively. The latter way includes setting correlation conditions, modifying correlation results interactively and saving results automatically. Thus both human being and computer are brought into full play. The characteristic of the former way is to solve complex case in a straightforward progressive way and to solve the lateral facies change effectively. The principle, implementation procedures and examples of this technique are given in this paer.
