摘要/Abstract

摘要： 营一D1井是2006年为揭示营城组内幕基准剖面而布置的探井。经揭示，营城组一段及下段岩性为：熔岩，包括流纹岩、松脂岩、珍珠岩和玄武岩；火山碎屑熔岩，包括角砾熔岩、凝灰熔岩和熔结凝灰岩；火山碎屑岩，包括火山角砾岩和凝灰岩；沉火山碎屑岩，包括沉凝灰岩和沉火山角砾岩。其岩相主要为喷溢相、爆发相和火山沉积相。物性测试资料显示，该井岩心平均孔隙度为15.17％，平均渗透率为1.51×10^-3μm²，孔渗线性相关性较好。根据压汞数据各参数将孔隙结构分为6类。综合评价物性与孔隙结构，将该井段划出4类储层：Ⅰ类为好储层，高-特高孔、特高渗，细、中、粗喉共存，粗喉比例大；Ⅱ类为次好储层，高孔、高渗，细喉为主；Ⅲ类储层为中等储层，中孔、中渗，细喉；Ⅳ类为差储层，中、低孔，低溶，细喉。

Abstract: Yingyi-D1 well, an exploratory well, was drilled to reveal the insider of standard section of Yingcheng Formation in 2006. Volcanic lavas, pyroclastic lavas, pyroclastic rocks and sedimentary pyroclastic rocks have been found in this well. The volcanic lavas include rhyolite, pitchstone, perlite and basalt. Pyroclastic lavas are consisted of breccia lava, tuff lava and ignimbrite. Pyroclastic rocks are mainly composed of volcanic breccia and tuff. Sedimentary pyroclastic rocks are mainly sedimentary tuff and sedimentary volcanic breccia. They mainly belong to effusive facies, explosive facies and volcanogenic sedimentary facies. The average porosity is 15.17％ and the average permeability is 1.51×10^-3μm². The porosity is linearly correlated to permeability. Based on the mercury injection capillary pressure data, the pore structures could be classified into six types. Synthetical evaluation of porosity & permeability and pore structure, the reservoirs were classified into four types. Type I is a perfect reservoir with high to super-high porosity and super-high permeability, coarse throat dominating. Type Ⅱ is good reservoir with high porosity & permeability, fine throat dominating. Type Ⅲ is a medium reservoir with medium porosity, medium permeability and fine throat. Type Ⅳ is a poor reservoir with medium to low porosity, low permeability and fine throat.

Key words: Yingcheng Formation, lithology, lithofacies, porosity & permeability, reservoir assessment
