摘要
锦16块化学驱试验区为中石油首批聚表复合驱重大开发试验区块之一,目前已完成前置段塞的注入进入主段塞注入阶段,为了及时准确地评价前置段塞注入效果,引入霍尔曲线及其导数曲线进行分析评价,试验区注入井霍尔曲线及其导数曲线表现出三类特征,反映了不同注入状况,本文分析影响注入效果的主要因素,为及时调整提供可靠依据。
Polymer and surfactant combination flooding in Jin 16 block is one of the important development test of CNPC,and has completed the pre- slug injection into the main slug injection phase. The Hall curve and its derivative curve analysis method was introduced to timely and accurately evaluate the effect of pre- slug injection.Hall curve and its derivative curves for injection wells exhibit three characteristics which reflect the different injection conditions. This paper analyzes the main factors influencing the effect of the injection,in order to provide a reliable basis for timely adjustment.
