摘要
克拉美丽气田是新疆油田公司在准噶尔盆地腹部发现的首个1000亿方级的大型火山岩气田,前期测试及生产资料表明气藏储层物性平面变化大,渗透性差,常规的回压法产能试井耗时长,天然气消耗大,修正等时试井延续测试期间流压很难达到稳定,影响气藏产能分析与评价。本文采用修正等时试井资料处理新方法来分析解释低渗透火山岩气藏修正等时试井资料,实例分析表明该方法处理低渗透气藏产能测试资料的可靠性,为分析评价火山岩气藏产能大小提供了一种可靠的方法。
Kelameili Gas Field is the first large-scale lava gas field discovered by XinJiang Oilfield Company in ZhunGaEr Basin abdomen,whose reserve is 10 billions steres.Early test and production data show that Gas reservoir petrophysical plane change is big and reservoir permeability is very low,and Consumption of natural gas in large quantities is much bigger than ever.so,it is difficult to reach the stable flow pressure while modified isochronal well test during Continuance testing,which influences gas reservoir productivity evaluation.This paper adopts a new method to analysze and interpret modified isochronal well test data in low permeability volcanic reservoir,It shows that the method to deal with low permeability gas reservoirs modified isochronal well test data by the example analysising is reliable,which provides a reliable method for analysis evaluation volcanic gas reservoir productivity.
