摘要
气藏保护研究需要进行储层气体速度敏感性评价实验,但目前尚无该实验的标准方法。常见的是仿照液体实验方法进行实验,却由于气体滑动效应的影响使实验结果不能真实反映储层特性。文章根据达西定律的基本原理,建立了气体速敏评价实验的数据修正处理方法,处理后的结果更有利于判断储层在气体流动时的速敏性及微粒运移状况。
A study of gas reservoir protection requires conducting an evaluation and experiment on velocity sensitivity. But currently there is no standard method. The common-used method is followed by the liquid experimental one. But the experimental result cannot really reflect the reservoir characteristics due to gas slippage effect. Based on Darcy's law, this paper establishes a data correction method for evaluating velocity sensitivity by gas. The corrected result is more favorable for judging the velocity sensitivity and particle migration when gas flows.
