2020油气勘探技术进展与趋势

Development and trend of oil and gas exploration technologies in 2020

为助力油气勘探的降本增效,对当前油气勘探形势和主要技术进展进行调研。在新冠肺炎疫情和低油价影响下,2020年全球油气勘探开发投资同比大幅下降,降幅达29.9%,油气剩余探明储量虽有小幅增长,但新发现量创21世纪最低纪录。全球油气公司正在迅速调整政策,升级技术,将智能化融入储层精细描述及建模技术,采用新型地球化学技术确定油气组分和运移路径,定量化预测勘探风险,使油气勘探的精度和效率显著提升。

In order to reduce the costs and increase efficiency of oil and gas exploration,the current global situation and technical progresses of oil and gas exploration are investigated.Under the influence of the new crown pneumonia epidemic and low oil prices,the global investment in oil and gas exploration and development in 2020 has fallen sharply year-on-year,with a decline of 29.9%.Although the remaining proven reserves of oil and gas have increased slightly,the number of new discoveries hit the lowest record in the 21 st century.Global oil and gas companies are rapidly adjusting policies,upgrading technologies,such as incorporating intelligence into fine reservoir description and modeling technologies,using new geochemical technologies to determine oil and gas components and migration paths,and quantitatively predicting exploration risks,so as to improve the accuracy and efficiency of oil and gas exploration.
