摘要： 九龙山气田珍珠冲组为非均质性很强的裂缝性致密砂砾岩储层。为明确开发层系，优选有利开发区块，利用岩心描述、铸体薄片观察、成像测井解释、全直径岩心分析等手段，对珍珠冲组开展了高分辨率层序地层划分，系统分析了储层沉积微相、岩石学特征、储集空间类型及裂缝分布特征，实现了对珍珠冲组裂缝性砂砾岩储层的精细描述。结果表明：①珍珠冲组可划分为3个中期旋回和6个短期旋回，有利储层为Ⅱ旋回扇三角洲前缘水下分流河道多层叠置形成的巨厚砂砾岩体；②珍珠冲组为裂缝-孔隙型储层，发育砾间溶孔、砾内溶孔及裂缝扩溶孔，储层孔隙度主峰为2.0%～4.5%，水平渗透率为1～100 mD，垂直渗透率为0.1～10.0 mD，低角度缝和网状缝显著改善了储层的渗流能力；③Ⅱ3和Ⅱ1小层裂缝发育，渗透率较高，为2个有利开发层系；④通过单层评价，多层叠合，优选出2个一类有利区和3个二类有利区。该研究成果对九龙山气田开发部署具有指导意义。

Abstract: Zhenzhuchong Formation in Jiulongshan gas field is known as fractured tight glutenite reservoir with strong heterogeneity. In order to make clear the development layer series and predict the favorable areas,high resolution stratigraphic sequences were divided and systematic studies were conducted on sedimentary microfacies, petrologic features,reservoir space types and fracture distribution of Zhenzhuchong Formation,by means of core description,casting thin section observation,imaging logging,full diameter core analysis,and thus to realize fine reservoir evaluation of fractured glutenite of Zhenzhuchong Formation. The results show that:(1) Zhenzhuchong Formation can be divided into three middle-term cycles and six short-term cycles,and favorable reservoirs were developed in hugely thick glutenites formed by superposed subaqueous distributary channels of fan deltaic front in middle-period cycle Ⅱ.(2) Zhenzhuchong Formation is fracture-pore type reservoir,comprised of inter-gravel and intra-gravel dissolved pores,fracture-expansion solution pores,with porosity mainly of 2.0%- 4.5%,horizontal permeability of 1-100 mD,vertical permeability of 0.1-10.0 mD,and the permeability of Zhenzhuchong Formation was highly improved by low angle fractures and fracture-networks.(3) Short-term cycle Ⅱ 3 and Ⅱ1 were selected as two favorable development layer series in which fractures were well developed and the reservoir permeability was higher than others.(4) Two first class favorable areas and three second class favorable areas were selected through single layer reservoir evaluation and integrative evaluation of multilayer composite. The study results have guiding significance for the development deployment of Jiulongshan gas field.

Key words: tight gas, glutenite reservoir, reservoir evaluation, Zhuzhuchong Formation, Jiulongshan gas field, Sichuan Basin
