【摘要】 川东南震旦系-志留系具有较好的勘探前景,但勘探程度极低。以地表露头、钻井资料及二维地震资料为基础,通过储层特征综合评价研究,认为上震旦统灯影组白云岩、下志留统石牛栏组颗粒灰岩为区内的主要储集岩,沉积相、岩溶作用及裂缝发育程度为储层发育的主控因素。储层沉积相区域对比研究表明,主要储层横向展布特征是:灯影组白云岩在研究区广泛且稳定分布,石牛栏组颗粒灰岩主要发育于泸州-赤水-道真以南的台地相区。

【Abstract】 The strata from Sinian System to Silurian System are new formations and fields with better exploration potential in the southeast area of Sichuan Basin,but the degree of prospecting is quite low.Based on the ground outcrops and drilling core samples,and two-dimensional seismic data in this paper,through a comprehensive evaluation and research of the reservoir characteristics,the authors clarifies that the dolomite of the Upper Sinian Dengying Formation and the grain limestone of the Lower Silurian Shiniulan Formation are main reservoir rocks in the research area,and the sedimentary facies,karstification,and the number of cracks are the main controlling factors of the reservoir quality.Though the regional correlation and study of reservoirs and sedimentary facies,they find the horizontal distribution characteristics of the major reservoir in the research area.
