摘要
为确保辽河油田齐40块中深层稠油油藏的高效开发,需对蒸汽驱的蒸汽腔运作进行有效监控,采取针对性调控措施,实现蒸汽有效驱替。针对该块油藏的地质特点,通过对监测资料、蒸汽驱开发动态信息、数模跟踪信息、油藏工程计算数据等分析研究,初步得出了蒸汽腔波及形态的5种模式、热连通及驱替阶段的主要驱替特征、汽驱不同开发阶段的蒸汽扩展速度等规律,并计算出了蒸汽和热水的波及体积范围。该研究更加直观细致地介绍了蒸汽驱的波及程度,为进一步开发调整提供了理论依据,为相似区块的研究提供了参考。
To ensure efficient development of medium-deep steam drive reservoirs in Block Qi40 of Liaohe Oilfield,it is required that the operation of a steam cavity in steam flooding should be monitored and corresponding measures should be taken to realize effective displacement of oil by steam.In view of the geology characteristics of the block and based on the analyses of the monitored data,development performance data,numerical simulation trace data,calculation data of reservoir engineering,etc.,5 steam sweeping modes of steam sweeping shapes,the main characteristics of thermal intercommunication and drainage period and steam expansion speed at different periods are obtained;and the swept volume scope by steam and hot water is calculated.The study presents intuitively and delicately sweeping effiviency of steam flooding,provides theoretical bases for development remodeling and provides a reference for the development of similar reservoirs.
