Status quo and prospect of thermal recovery of dense oil in Shengli oil field

Introduced are the present situation and primary contra- diction up against in the development process of ordinary wa- ter drive dense oil pool,ordinary dense oil pool of thermal recovery,extraordinary dense oil pool of high water content and extremely dense oil pool.On the base of characters and present development situation of dense oil pool in shengli oil field,and the development experience at home and abroad, further suggested is how to fulfill the matching techniques such as steam drive,water blockage and injection profile modification at high temperature,chemical agent assisting thermal recovery and combustion drive.
