加密井快速优化技术在西非深水浊积砂油藏精细描述中的应用——以Bata油田为例
Application of rapid infill-well optimization technology in fine-scale description of deep-water turbidite reservoirs in West Africa:A case study of the Bata oilfield
摘要
Abstract
Differing from onshore oilfields,deep-water oilfields center their exploitation on economic efficiency,employing a strategy of achieving higher production via fewer wells while maintaining formation energy balance.Their exploitation plans are flexible and empha-size dynamic oilfield monitoring,allowing for adjustment and optimization during the exploitation,thereby achieving fast and efficient ex-ploitation.Therefore,the placement of infill wells serves as a crucial step for stable production of deep-water oilfields in the middle and late exploitation stages.Considering oil reservoir characteristics and production well waterflooding,this study investigated the deep-water turbidite reservoirs in the Bata oilfield,West Africa.A rapid infill-well optimization plan was proposed based on a tectono-sedimentary study of the oil reservoirs.The proposed plan centers on predicting high-quality turbidite sand bodies using the prestack amplitude ver-sus offset(AVO)attributes,identifying waterflooding fronts through time-lapse seismic surveys,performing a fine-scale description of turbidite sandstone reservoirs and predicting the distributions of residual oil in the reservoirs.The implementation of the proposed plan demonstrated satisfactory production performance.Specifically,the infill wells achieved daily crude oil production of 12,000 barrels,es-tablishing them as a primary contributor to oilfield production.This result validates the effectiveness of rapid infill-well optimization technology.Overall,this study provides a significant reference for enhancing the oil recovery of deep-water reservoirs through the place-ment of infill wells for deep-water oilfields in the middle and late exploitation stages.关键词
