Abstract

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
