摘要
在油气井的试油测试资料中,压力恢复曲线有时会出现下滑现象,常被认为是施工失误所致。本文以实际资料为例,分析了“下滑恢复”的压力响应特征和影响因素,认为只在低渗透地层有可能产生“下滑恢复”现象,并提出了避免“下滑恢复”的施工建议。
In well testing data, slipping phenomena appears sometimes on build-up curves which is thought to be caused by operation fault. The paper takes actual data as examples to analyze pressure response and influencing factor of it and summarizes that only in low percolation formation, slipping phenomena may produced and the next operation suggestions are provided.
