Abstract
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.
