摘要: 井筒常流量气井携液临界流量的确定主要取决于井筒的截面面积。对东海西湖凹陷多层合采气井的调查发现,积液面位于井筒生产滑套处的井数占调查井数的39%。为了揭示井筒变流量气井积液的多样性,以东海西湖凹陷多层合采气井为研究对象,从建立区域携液临界流量模型入手,形成了一套由井筒变流量气井携液临界流量的确定方法,包括模型系数值拟合数据的选择、最易产生积液的井筒节点的筛选条件、井筒节点携液临界流量到气井携液临界流量的转化方法等。研究认为:多层合采气井的分段式流量分布,是导致多层合采气井积液现象普遍高于单层开采井,以及积液面通常处于生产滑套处的主要原因,这对多层合采气井的合理配产研究具有一定的借鉴意义。
