Abstract: Hailar Basin is a Mesozoic-Cenozoic continental rift basin located on the northern border of China. After more than 60 years of continuous exploration, the main oil-bearing series has entered the mid-late stage of development. Shallow buried, large-scale, and easily-discovered structural reservoirs have been almost completely drilled and explored, it is more and more difficult to increase reserves in recent years. Through systematically reviewing the oil-gas exploration history in Hailar Basin, in combination with current exploration and development practices, it is pointed out that to exploit the less explored subsag areas and deep strata is essential to open a new situation for oil-gas exploration in Hailar Basin. The basin has great exploration potentials in four fields:shale oil in the condensed section of Nantun Formation, glutenite lithologic reservoir in Tongbomiao Formation, oil reservoir in Jurassic Tamulangou Formation, and interior reservoir in bedrocks of buried hills, of which the total oil resources are predicted to be 5.96×108 t. The oil reservoirs in new fields and the discovered reservoirs have spatial complementarity, thus forming the petroleum system in complex rift basins that involves multiple types and multiple strata from middle-shallow to deep formations, from slope belts to subsag areas, and from conventional to unconventional fields, and displays ordered distribution and differential enrichment of oil reservoirs, and its exploration potentials can be further explored.

Key words: Hailar Basin, oil-gas exploration, subsag area, deep strata, new field, new type

摘要: 海拉尔盆地是位于中国北部边陲的中生代—新生代陆相断陷盆地,经过60余年的持续勘探,主力含油层系已进入开发中后期阶段,埋藏浅、规模大、易发现的构造油藏几乎已钻探殆尽,近年来的规模增储难度日益增大。通过系统回顾海拉尔盆地的油气勘探历程,结合当前勘探开发实践,指出向勘探程度较低的洼槽区和深部层系进军是打开海拉尔盆地油气勘探新局面的必经之路。海拉尔盆地在南屯组凝缩层段页岩油、铜钵庙组砂砾岩岩性油藏、侏罗系塔木兰沟组油藏和基岩潜山内幕油藏4个新领域具有较大的勘探潜力,石油总资源量预测达5.96×108t;新领域油藏与已发现的油藏具有空间互补性,构成了一个更加完整的从中—浅层到深层、从斜坡带到洼槽区、从常规到非常规的多层系多类型且油藏呈有序分布、差异富集的复杂断陷盆地含油气系统,可进一步挖掘其勘探潜力。
