摘要
本文通过分析电缆式地层测试器测压过程中"超压"及"管储效应"两个异常因素,提出了快速获取真实地层压力的测试方法,并通过中海油服研制的ERCT仪器测压实例证明了其实用性和可靠性。分析结果表明,在超压的低渗地层中,该测试方法不仅能够快速获取地层压力,而且比常规方法更加可靠,有良好的推广使用价值。
Through analysing two anomalous factors——superpressure and pipe storage effect in pressure measurement with wireline formation tester,the paper presents a quick testing method to get real formation pressure. Application of ERCT tool made by COSL proved that the method is practical and reliable.The result shows that the testing method can not only get formation pressure quickly in low permeability formation with superpressure, but also be reliable. It has favorable popularisation value.
