摘要(Abstract)：

徐深Ⅰ井营城子组及其以下地层钻遇了4层大段火山岩和砾岩,获得了产能和产气深度上的新突破。通过偏光显微镜、图像、扫描电镜、电子探针、阴极发光、X-荧光光谱、核磁和CT等分析方法,结合录井、测井等手段,系统研究了该井火山岩和砾岩产气层的岩性、物性特征、孔隙类型、孔隙成因及演化、裂缝类型、成因及分布等,对储层进行了综合评价。结果表明,砾岩孔隙类型以次生的裂缝和溶孔为主;晶屑凝灰岩孔隙为风化淋滤作用形成的长石溶孔;集块岩主要孔隙类型为炸裂缝和基质内气孔,孔隙和裂缝明显受后期成岩作用的改造。储层的多样性和独特性是该井获得产能突破的主要因素之一。
The drilling of deep well Xushen l has shown that four huge thickness of volcanic rocks and conglomerates are found in and under the Yingcheng formation and brings about an important breakthrough for natural gas production and productive deepth. By applying many new techniques, such as polarization microscope, im-age analysis, scanning electron microscope, electronic probe, cath-odoluminescence, fluorescent X-ray spectroscopy, NMR, CT, well logging, this paper thoroughly studies lithology, physical characteris-tic,the type and distribution of pore and fracture and so on. Also it evaluates the reservoir of the well Xushengl. It is shown from study that the type of pore in the conglomerate is the secondary fracture or corroded pore, in the crystal tuff is feldspar corroded pore formed by weathering and corrosion, in agglomerate is exploding fracture or primary vesicular. The pore and fracture are obviously reformed by post-diagenesis. Reservoir diversity and particularity are the one of main factors for the breakthrough of natural production.
