摘　　要：志留系砂岩是塔里木盆地重要的油气勘探层系之一,也是阿北-顺北区块有望获得油气突破的重要勘探目的层。通过对阿北-顺北地区构造演化、烃源岩、志留系储盖组合、油气运移聚集及保存等成藏条件的研究,认为该区是一个在加里东中期构造运动基础上发展起来的古构造斜坡,长期处于油气运移聚集的有利指向区;寒武-奥陶系烃源岩是该区主力烃源岩;志留系红色泥岩与下砂岩段构成的储盖组合,是本区油气勘探有希望获得突破的重要组合;认为本区志留系油气勘探应以寻找古油藏为主,古构造稳定发育区、非构造圈闭发育带、盖层发育带是油气勘探的优选区域。The sand formations in Silurian are the important formations for oil-gas exploration in Tarim Basin. It is also a hopeful target zone of oil-gas exploration in Abei-Shunbei block. According to the study of oil accumulation conditions including structural evolution, hydrocarbon source rocks, combination of reservoir and cap, oil-gas migration, accumulation and preservation etc., it is thought that Abei-Shunbei block is an ancient structural slope based on mid-caledonian tectogenesis and which is located in the favorable area of oil and gas accumulation. Major hydrocarbon source rocks are in the Cambrian and Ordovician. The combination of reservoir and cap which is made of red shale and the sand reservoir under it in Silurian is hopeful combination for oil-gas exploration in the region. Main target of oil-gas exploration in Silurian should aim at ancient reservoirs, stable area of ancient structures, non-structural traps and cap-growing belt.
