摘要
朝阳沟油田试验区扶余油层具有低渗、低产特征．采用砂岩油藏黑油模拟器，应用数值模拟方法研究剩余油分布特征，进行综合调整方案动态预测．结果表明：试验区北块剩余油分布较多，是今后调整挖潜的主要地区．有效注水方式为线性注水．综合调整措施以周期注水为主，同时，可以考虑早期分层注水、堵水以及不均匀加密等措施．分层注水应该早进行．严重水淹油井转注有一定的增产效果，但投产费用增大．
On the basis of numerical simulation results of black oil model for sandstone reservoir, we focus on studying the residual oil occurrence and dynamic predicting on synthetic adjustment of Fuyu formation with low permeability and low daily output in the trial zone, Chaoyanggou oilfield. The numerical simulations reveal that the northern part of the section is the key target area for the future adjustments of oil enhancement because of the occurrence of much more residual oil. The effective water injecting plan is linear water injection. The reasonable synthetic adjusting treatments are periodically water injecting, layer injection in the early stage, as well as irregularly infill drilling and water plugging. The transform of production wells with higher water content to injection wells may enhance the oil production to some degree,but will cost much.
