摘要: 苏里格气田苏49区块盒8下亚段发育典型致密砂岩气藏,气水分布规律复杂且单井产气量差异大,为了明确储层非均质性对气藏分布和气井产能的影响,实现气田高效开发,在精细地层划分对比的基础上,充分利用钻测井、测试分析和气井生产资料,对储层层内、层间和平面非均质性进行系统研究。结果显示:①研究区盒8下亚段层内和层间非均质性均较强,其中盒8下2砂层组储层物性总体较差、层内夹层多、砂体垂向和平面上连通性差,其非均质性要强于盒8下1砂层组;②平面上,研究区西部的层间和平面非均质性均严重,中部苏176三维区及附近的盒8下1砂层组砂体连通性好,存在相对高孔高渗带,夹层较少,有利于天然气富集并成藏;③储层非均质性对含气性、气层宏观展布和开发效果影响均明显,相对好的储层物性、连通性和低的夹层频率均是天然气富集和高产的关键。该结果可为研究区及类似地区井位部署和后期开发提供参考。
