摘要: 随着火山岩油气藏勘探不断取得重要进展,火山岩发育区已从油气勘探的禁区转变为靶区,但对于岩浆侵入油藏的石油地质研究还相对较少。结合岩浆特点和侵入活动特征,开展渤海湾盆地岩浆侵入活动对烃源岩演化、围岩储集性能、油气运移、油气保存等油气成藏特征分析研究,进一步明确了渤海湾盆地岩浆侵入油气藏重点勘探目标。结果表明,岩浆侵入有利于烃源岩演化、储层发育、圈闭形成等后期油气成藏。该研究对岩浆侵入油气藏勘探开发及综合地质研究具有一定促进作用。

Abstract: With the continuous progress of volcanic oil and gas reservoir exploration, the volcanic development area has been transformed from a restricted area to a target area for oil and gas exploration, but there are relatively few studies on the petroleum geology of magmatic intrusion oil reservoirs. Based on the characteristics of magma and magmatic intrusion, this paper analyzes the reservoir forming characteristics in Bohai Bay Basin, such as hydrocarbon source rock evolution, surrounding rock storage performance, oil and gas migration, and oil and gas preservation, and further defines the key exploration targets for magmatic intrusion oil and gas reservoirs in Bohai Bay Basin. Results indicate that magmatic intrusion is beneficial to oil and gas reservoir forming for hydrocarbon source rock evolution, reservoir development and trap formation in later stages. This research can promote the exploration and development of magmatic intruded oil and gas reservoirs and the comprehensive geology research.

Key words: magmatic intrusion, hydrocarbon source rock evolution, oil and gas migration, oil and gas reservoir type, oil and gas reservoir characteristics, Bohai Bay Basin
