【摘要】 结合三维地震数据及井上的裂缝资料建立了莲花山-张家坪须二段气藏的三维裂缝密度模型、裂缝空间网络模型及裂缝系统的孔、渗属性模型。研究表明:莲花山-张家坪须二段气藏有效砂岩厚度均值为24m,在LH101、LH000-4、zhangjia1等储层较厚处,有效砂岩厚度超过30m,在sanhenan1、LH000-1井等区域,有效砂岩厚度不足10m。莲花山-张家坪须二段气藏基质孔隙度均值为5.12%,在LH101、LH000-4井区,孔隙度超过6.0%,其它区域,孔隙度在5%以下。更多还原

【Abstract】 Seismic structural interpretation and stratigraphic correlation achievements of 3D structural model and three-dimensional grid model were built in this paper,the properties of three-dimensional model of the matrix,including facies,porosity,permeability and saturation model were built and studied based on log interpretation results.The study showed that the Lianhua Shan-Zhangjia Ping Xu 2 Duan gas reservoir effectively mean sandstone thickness is 24m,the effective sandstone thickness of reservoir LH101、LH000-4、zhangjia1,are more than 30m,the sandstone thickness of sanhenan1、LH000-1 wells are less than 10m.The average porosity of Lianhua Shan-Zhangjia Ping Xu 2 Duan gas reservoir is 5.12%.The porosity of area near LH101、LH000-4 well is more than 6.0%,but the porosity of other area is less than 5%.更多还原
