渗漏检测技术在注入井分层测压中的应用

Leakage Detection Technology in Layered Pressure Measurement of Injection Wells

在注入井分层测压的测试过程中,如果存在渗漏现象,将导致测压数据不准确,影响对地层注采能力大小的判断。针对这一问题,将渗漏检测技术应用在注入井分层测压中,通过分析振动值曲线了解分层测压的真实情况,并在实践中获得定量解释标准。通过在4种不同渗漏情况下的应用,验证了该技术的有效性,为解释人员对注入井分层测压给出准确解释提供数据。

In the process of layered pressure measurement in injection wells,leakage will lead to inaccurate pressure measurement data and affect the judgment of the injection-production capacity of the formation.In view of this problem,the leakage detection technology is applied to the layered pressure measurement of injection wells.The real situation of layered pressure measurement is known by analyzing the vibration value curve,and the quantitative interpretation standard is obtained in practice.The effectiveness of the technique is verified by the application under four different leakage conditions,and the data can be provided for the interpreter to give an accurate interpretation of the layered pressure measurement in injection wells.
