摘要 现代产量递减分析方法综合考虑流动压力和产量之间关系,通过特征曲线等分析求取地层相关参数并计算单井动态储量,取代了试井的部分功能。在对生产数据进行分析、处理后,采用现代产量递减方法对各单井的生产情况进行动态分析,提出了分析中可能会遇到的几种问题,计算了表皮系数、渗透率及动储量等参数,为井后期开发及井网调整部署提供了依据。经分析,目前吉拉克凝析气田由于边底水上升快,单井控制总储量明显小于气田地质储量,在分析基础上结合地质分析及数值模拟研究成果新钻3口水平井,随着井网逐渐加密,井储量控制程度明显增大。 Combined with the correlation of well bottom-hole pressure and well production rate,the modern production decline analysis can give reservoir properties and single well dynamic reserve through type curve analysis.This method can substitute part functions of well test analysis.After the production data analysis of the field,the modern production decline analysis is applied for all single wells,and several problems are solved for reference.The skin factor,permeability and well dynamic reserve are calculated,w...
