莺歌海盆地乐东区隐蔽性暗点气藏成因分析及勘探中的应用OACHSSCD

With the continuous advancement of progressive exploration in the Yinggehai Basin,bright-spot gas detection methods have yielded fewer and fewer newly discovered reserves,failing to meet the demands of gas field development.There is an urgent need for new insights to support the discovery of additional reserves.Through in-depth research and analysis of subtle traps in the Yinggehai Basin,this study reveals that their formation is attributed to factors such as diapir-related fractures and shielding by overlying gas zones,and classifies them into four types of subtle traps.By proposing an interpretive processing workflow that approximates the restoration of true reservoir amplitude response,this study provides a reference for effectively identifying subtle traps,thereby enhancing the accuracy of gas-bearing prediction.
