生产数据分析技术在普光M1井的应用

Application of Production Data analysis in well test of M1 well at Puguang fields

针对普光气田高含硫化氢、二氧化碳、气井产量大,施工操作复杂,风险较高,难以有效监测气田开发这一难题,本文引进生产数据分析技术,以普光气田M1井为例,对其184天的产量、井口压力等生产数据进行了解释分析,确定了单井控制储量、可采储量、表皮系数等重要参数,其结果与常规试井的解释结果误差较小,并在此基础上对该井以不同产量生产一段时间之后的压力进行了预测,科学指导了该井的合理开发,形成了一套适合于普光高含硫气田且与常规试井分析等效的动态分析新技术。

In Puguang gas field,with high hydrogen sulfide、carbon dioxide、gas well production、construction complex operation、high risk,it can not effectively monitoring field development.So this paper introduced the production data analysis technique,with the puguang gas field M1well as an example,which analysises the production、head stress of 184days,and confirmed the single well control reserves、recoverable、skin,and so on;furthermore predicted the Well pressure in different yield production after a while.This technique guides the development of the well rationally,and being suitable for puguang gas field which is also equivalent with the traditional well test analysis.
