塔里木盆地塔中北坡奥陶系一间房组储集层主控因素分析
Main Controlling Factors of Reservoir in Ordovician Yijianfang Formation on the Northern Slope of Middle Tarim Basin
摘要
Abstract
Based on the analysis of core observation, rock thin sections, logging data and a variety of testing data of the Middle Ordovician Yijianfang Formation on the northern slope of middle Tarim Basin, reservoirs are mainly distributed in grain limestone of intra-platform shoals. The main reservoir types in this area are fractured reservoirs, fractured-vuggy reservoirs and pore-cave reservoirs. The controlling factors of reservoir genesis are sedimentary microfacies, faults and dissolution. The carbonate shoals provide the early material basis for the later selective dissolution. Meteoric-water dissolution and burial dissolution improved the properties of reservoir to some extent. The multi-period activities of the NE-trend faults played a key role in controlling the high quality reservoir.关键词
