摘　　要：针对八面河油田面138区沙四段薄层油藏多轮次热采后,地层能量降低,汽窜严重,单一注气热采开发效果不佳的问题,从各项技术的机理、参数优化两个方面,总结了不同油藏开发的热化学复合吞吐技术,并进行现场矿场试验。研究表明,氮气辅助吞吐、氮气泡沫调剖和DS/DCS技术有效解决该区块的主要矛盾,提高了整体开发效果,为八面河油田稠油热采效益开发、绿色开发提供了技术支撑。Addressing the challenges of declining formation energy,severe steam channeling,and poor performance of single steam injection in multi-cycle thermal recovery in thin-layer reservoirs of the fourth member of Shahejie Formation in Mian 138 block of Bamianhe Oilfield,this study explores thermochemical composite huff and puff technology.It summarizes the mechanisms and parameter optimization of various techniques tailored to different reservoirs and conducts field trials.Results show that nitrogen-assisted huff and puff,nitrogen foam profile control,and DS/DCS technologies effectively resolve key issues,improving overall development outcomes and providing technical support for efficient and green heavy oil thermal recovery in Bamianhe Oilfield.
