为降低稠油热采成本,以燃烧原油生产蒸汽进行热力开采的开发方式需要改变，同时需要减少注入水对油层造成的冷伤害，因此开展了干热岩辅助采油可行性研究。干热岩辅助采油技术是利用干热岩抽取地下热能加热油层，以降低原油粘度、提高原油流动能力。在技术配套方面，无论钻深井，还是稠油热采技术，都是成熟的。干热岩的热能源于核幔边界的地热,分布广泛、清洁、可再生。研究表明，干热岩辅助采油技术针对性较强，是对现有蒸汽吞吐+蒸汽驱热采技术的有效继承，技术上具有可行性，并有可能推动相关技术的发展，符合中国节能减排的基本国策。建议在有利区块率先开展先导试验。

For reducing heavy oil thermal cost,development scheme such as producing steam by burning crude oil to achieve heavy oil need to change. Also we need to reduce formation damage, so we launched hot dry rock(HDR) assisted oil recovery feasibility study. HDR assisted oil recovery extracted heat reservoir of underground thermal energy by hot dry rock to reduce oil viscosity and improve oil mobility. The technical support facilities regardless of drilling deep or heavy oil thermal recovery technologies are mature. HDR heat from geotherm in core-mantle boundary, were widely distributed, clean and renewable. Studies have shown that hot dry rock assisted oil recovery technology had strong pertinence and effectively inherited cyclic steam injection and steam drive technology, and technically feasible. So it may promote the development of related technology and is in line with China's basic national policy of saving energy and emission reduction. It is advised that hot dry rock assisted oil recovery pilot test should be carried out firstly in the favorable block.
