Quantitative characterization of buried-hill reservoirs:A case study of a buried hill in Huizhou sag,Pearl River Mouth Basin
摘要
Abstract
The ancient buried hills formed by complicated tectonic movements in the Huizhou sag,the Pearl River Mouth Basin fea-ture large buried depth and strong reservoir heterogeneity.After forty years of exploration and development,it becomes increasing-ly challenging to characterize sweet-spot reservoirs and complicated fractures inside buried hills.Based on the genetic mechanism of buried-hill reservoirs,we investigate major controls on reservoirs in weathered fracture zones and internal fracture zones and estab-lish key techniques for quantitative prediction of buried-hill reservoirs.For weathered fracture zones,we derive a new elastic param-eter from the Keys-Xu model to improve sweet-spot identification and use prestack elastic inversion to predict sweet-spot reser-voirs.For internal fracture zones,we use ant tracking to estimate dominant azimuths of fractures and then integrate equally weigh-ted azimuthal data for fracture prediction.These techniques have offered effective support to the exploration and evaluation of a buried hill,H,in the Huizhou sag and may be applied to buried-hill exploration in additional prospects in the Pearl River Mouth Basin.关键词
