注水井压降曲线特征分析与应用

Analysis for the Pressure Drop Curve Characteristics in Injection Well and Its Application

以注水井压降曲线为研究对象,对近期取得具有特征的200多条压降曲线进行综合分析,通过形态归类评价,结合实例进行了动态验证,对一口井阶段注水压降曲线特征的变化进行了跟踪测试与分析,加深了对各类注水井组油藏的认识,对注水井网调整及评价有一定的指导和借鉴作用。

Taking the pressure drop curves in injection well as study examples,a comprehensive analysis for more than 200 of drop curve characteristic is made. By morphological classification assessment,combined with examples of dynamic verification,and tracking and analysis of changes of a well water pand phase pressure drop curves,understanding to every types of injection wells reservoirs are deepened,which has some guidance and reference for adjustments and evaluation of injection wells net.
