全球凝析油资源潜力与勘探领域

凝析油是指从凝析气田的天然气中凝析出来的液态组分，其开发经济性高。"十三五"（2016—2020年）规划期间，以成藏组合为单元，采用常规、非常规油气资源评价方法，自主评价了全球不同级次的常规凝析油可采资源量和富含凝析油的页岩油技术可采资源量，明确了不同类型凝析油的潜力与分布。研究表明，全球常规凝析油可采资源总量为534.9×10⁸t，截至2020年底累计产出55.4×10⁸t，凝析油剩余2P可采储量为174.6×10⁸t，待发现可采资源量为241.8×10⁸t，已发现凝析油的可采储量增长量为63.1×10⁸t。全球凝析油具有广泛分布、集中富集的特点。近10年凝析油勘探新发现向深层和深水区延伸。页岩油藏是重要的凝析油储量增长点，自主评价全球页岩油技术可采资源量为738×10⁸t，预测与其伴生的凝析油可采资源量为（140~192）×10⁸t。评价结果表明全球凝析油可采资源丰富，为未来常规凝析油和页岩油勘探领域指明了方向。

Global condensate oil resource potential and exploration fields

Condensate oil refers to the liquid component condensed from the natural gas of condensate gas field, which is characterized by high economic feasibility. During the period of "the Thirteenth Five-Year Plan" (2016-2020), using the conventional and unconventional oil and gas resource evaluation methods for reservoiring combinations, recoverable resources of conventional condensate oil and technically recoverable resources of the shale oil rich in condensate oil at different levels in the world have been obtained through independent evaluation, and the potential and distribution of different types of condensate oil have also been determined. Research suggests that the total recoverable resources of conventional condensate oil in the world amount to 534.9×10⁸t, the cumulative output reached 55.4×10⁸t by the end of 2020, the remaining 2P recoverable reserves of condensate oil is 174.6×10⁸t, the undiscovered recoverable resources of condensate oil total 241.8×10⁸t, and the reserves growth of discovered condensate fields accounts to 63.1×10⁸t. On a global scale, condensate oil is characterized by wide distribution and concentrated accumulation. In the past 10 years, new discoveries in condensate oil exploration have been found in deep layers and deep waters, and shale oil reservoir has become an important growth point of condensate oil reserves. According to the independent evaluation, the amount of technically recoverable shale oil resources in the world can reach 738×10⁸t, and the recoverable resources of associated condensate oil are estimated to be (140~192)×10⁸t. The evaluation results indicate that the recoverable resources of condensate oil are still abundant in the world, which points out the direction for the future exploration of conventional condensate oil and shale oil.
