砂岩多层气藏多层合采合理配产方法研究

PROPER PRODUCTION-ALLOCATING METHOD OF COMMINGLING PRODUCTION FOR SAND GAS RESERVOIRS WITH MULTIPLE PAYS

砂岩气藏开发过程中气井出砂是一个较为普遍的问题,若出砂较为严重,就会严重制约气井产能和气田开发效益的提高。为了防止地层出砂、提高气井单井产能,多层砂岩气藏采用多层合采方式是一条有效的途径。为此,文章提出了两种多层砂岩气藏多层合采防止地层出砂、提高气井产能的合理配产方法,实例计算结果表明,临界渗流速度法配产结果与气井实际产量吻合程度较高,该成果为多层砂岩气藏多层合采气井的合理配产提供了新的思路和技术手段。

Sand producing of gas wells is a common problem during exploitation of sand gas reservoirs, which will influence the productivity of gas wells and the development benefit of the gas field if sand is produced severely. To control sand producing of reservoirs and improve the productivity of single well, commingling production is an effective way for sand gas reservoirs with multiple pays. So, two proper production-allocating methods are proposed for commingling production of sand gas reservoirs with multiple ...
