	<span style=\"font-size:14px;line-height:1.5;\">陆梁地区侏罗系西山窑组一段(西一段)广泛发育一套三角洲相碎屑岩，是致密储层勘探的主要产油层段之一。通过岩心和薄片观察，结合岩石物性测试分析，探讨了陆梁隆起陆9井区西一段碎屑岩储层的发育特征，建立了储层分类评价标准，明确了有利区分布。结果表明：区内西一段储层孔隙度平均为13.8%，渗透率一般为2.1 mD，属于中孔、低渗储层。不同岩石结构的储层与孔隙结构有很大差异，储层非均质性强，表现出多重孔隙介质特征。有利储层受沉积微相和成岩作用等因素的综合控制，其中水下分流河道及河口砂坝的次棱角状中-细粒砂岩是区内岩性油藏的有利勘探目标。<br />
J<sub>2</sub>x<sub>1</sub> from the Jurassic formation, where a set of delta facies clastic rocks are widely developed, is one of the main oil production zones for dense reservoir exploration. Through the analysis of core and thin section observation, combined with rock physical analysis, the characteristics of rock development in J2x1 of Wellblock 9 in Luliang Uplift are discussed; a reservoir classification evaluation standard is established; favorable distribution of exploration areas are clarified. The results show that the reservoir porosity in J2x1 is 13.8% in average, permeability is 2.1 mD in general; it belongs to a reservoir with middle porosity and low permeability. There exists great difference between reservoir and porosity in different rock structures, where reservoir heterogeneity is strong with characteristics of multiple porous media; the favorable reservoirs are controlled by sedimentary microfacies and diagenesis, in which the subangular mid-fine sandstone in the underwater distributary channel and river-mouth bars is the beneficial target of exploration for lithologic reservoirs in the area.</span>
