中原油田油水井窜漏识别测试工艺研究及应用

氧活化测井是评价油水井窜漏的主要方法之一，目前主要应用于水井的窜漏识别，在油井窜漏识别上应用较少，由于该方法存在一定的局限性，某些井况下无法判别窜漏的具体位置。分析了中原油田油水井的主要窜漏类型，研究了不同窜漏类型的油水井在注入、气举条件下测试管柱优化方法，对不同测试工艺下找漏找窜的应用效果进行了分析。研究表明，测试工艺的优化提高了测试成功率和窜漏识别精度。

Research and Application of Channeling and Leakage Detection in Zhongyuan Oilfield

The oxygen activation logging was a main method to evaluate the channeling and leakage of oil and water well, it was adopted to identify the channeling and leakage of water wells, but it was less applied in oil well, and because it had certain limitations, it usually could not determine the accurate location of channeling and leakage. The article analyzed three main channeling and leakage types of oil and water wells in Zhongyuan Oilfield, it studied different methods for casing string testing of well injec...
