极限油套压差法在廖家场气藏泡排中的应用

泡沫排水采气现场施工参数主要涉及到不同气井的加注时机及加药量两项参数。加药时机过早,会增加施工成本,加药时机过晚,会影响泡沫排水效果;因此准确把握加药时机,是提高泡沫排水采气效果的关键。在比较准确地计算井筒积液量的基础上,通过分析历史生产数据,研究不同气井承受积液能力,根据气井的压差变化,采用极限油套压差变化来指导加药时机。

Application in extreme pressure differential method of oil gas field in liao bubble drainage

Foam drainage construction site parameters of different gas mainly involves the filling time and dosage two parameters.Dosing time too early,increase construction cost,dosing time too late,will influence foam drainage effect,So accurately grasp the opportunity to improve and adding gas drainage effect is the key to foam.In more accurately calculated based on the quantity of borehole effusion,through the analysis of the historical data,the bear ability,according to the gas fluid gas pressure differential,limit of oil pressure difference changes to guide dosing opportunity.
