马朗凹陷火山岩储层预测技术研究

从目前火山岩储层预测面临的难点出发,分析了影响火山岩储层成因的关键因素,并依据地质成因制定火山岩储层预测研究的技术方案,即从利用重、磁、露头开展的区域预测;到以层序-结构解释为主体的方向预测;从以多属性、反演等多方法联合的目标预测,到以裂缝分析、含油气检测为主的甜点预测,形成了火山岩油藏研究从区域定凹选带,定带选区到局部储层预测的一整套技术流程,有效的指导火山岩油气藏的勘探。该方法在三塘湖盆地马朗凹陷火山岩油气藏勘探应用中取得了较好的效果。

Study on Prediction Techniques of Volcanic Reservoir in Malang Sag

Based on the current difficulties of volcanic reservoir prediction,the key elements effected on the origin of volcanic reservoir are analyzed.Technique schemes on the research of volcanic reservoir prediction are established based on the geologic origin.That is,from regional forecast using gravity,magnet and outcrops to orientation forecast taking the sequence-structure interpretation as the main part;from target prediction of combination of multi-method such as multi-attribute,inversion method to sweet pre...
