东海M构造中深层低渗气藏"甜点"预测技术OA北大核心CSTPCD
"Sweet spot"prediction technique for mid-deep low permeability gas reservoirs in M Structure of East China Sea
近年来,构造-岩性复合型油气藏已逐渐成为东海"扩储增产"的重要领域,提高"甜点"储层钻遇率对于勘探开发一体化设计的部署与落实具有重要意义.研究区低渗气藏储层厚、埋深大,内部非均质性强,孔渗关系复杂,地球物理响应特征差异小,亟待开展低渗气藏"甜点"储层的精细表征研究.以地震岩石物理为驱动,利用杨氏阻抗Eρ区分碎屑岩储层与非储层,通过分类寻优认为,剪切模量μ为洁净、粗粒、高渗透率优质储层的综合敏感弹性因子.为了削弱岩石骨架孔隙度的影响,采用高灵敏烃检…查看全部>>
In recent years,structural-lithological complex reservoirs have gradually become the key in reservoir expansion and production in the East China Sea.The low permeability gas reservoir in the middle and deep low-permeability gas reservoir in the M Structure of the East China Sea was studied.The study area has large burial depth,strong internal heterogeneity,and complex porosity-permeability relationship,but little difference in geo-physical response character…查看全部>>
