-
摘要: 为进一步明确“十五五”期间低勘探程度凹陷油气勘探方向，在对渤海湾超级盆地近期油气勘探发展形势和新进展分析的基础上，揭示油气来源的新认识，系统梳理该认识适用性并开展排队优选研究，最后提出低勘探程度凹陷勘探思路.研究结果表明：低勘探程度凹陷油气来源存在3点新认识，一是咸化湖富有机质藻源岩具有早期生烃、多期生烃机制，二是局部热异常及咸化湖烃源岩揭示小而浅凹陷自身具有一定的生烃潜力，三是油气具有来源于相邻主力富油凹陷长距离输导的可能.根据目前勘探进展，低勘探程度凹陷的理论技术成果将助推渤海湾盆地石油天然气增储上产，对保障东部地区能源供应、拉动着区域社会经济建设具有重要理论和实践意义.Abstract: To further clarify the direction of oil and gas exploration in low exploration degree depression during the "15th Five-Year Plan" period, based on an analysis of the recent development and progress of oil and gas exploration in the Bohai Bay super basin, this study reveals new insights into the sources of oil and gas, systematically sorts out the applicability of these insights, conducts prioritization and selection research, and finally proposes exploration ideas for low exploration degree depression. The results reveal three new understandings about the sources of oil and gas in low exploration degree depression. First, there is an early hydrocarbon generation and multi-stage hydrocarbon generation mechanism in organic-rich algal source rocks of salinized lakes. Second, local thermal anomalies and hydrocarbon source rocks in salinized lakes reveal the potential for hydrocarbon generation in small and shallow sags. Third, the oil and gas originate from long-distance transport in adjacent major oil-rich sags. According to the current exploration progress, the theoretical and technological achievements in low exploration degree depression will boost the increase in reserves and production of oil and gas in the Bohai Bay basin, which has important theoretical and practical significance for ensuring energy supply in the eastern region and driving regional socio-economic development.
