    After nearly 40 years of development and practice,a relatively complete series of development technologies with Shengli characteristics has taken shape during the heavy oil reservoirs development and a significant development effect has been achieved in Shengli Oilfield. In October 2020,the cumulative production of heavy oil in Shengli Oilfield exceeded 100 million tons. Since“The Twelfth Five-Year Plan Period in 2011-2015”,multiple technologies have been developed to address severe situations such as low oil prices and high steam injection costs,including the HDNS(horizontal well+dissolver+nitrogen gas+steam injection)technology for super heavy oil in shallow and thin reservoirs,the chemical steam flooding technology for deep heavy oil reservoirs,the quality and efficiency enhancement technologies for heavy oil reservoirs,and the viscosity reduction cold recovery technology. These technologies supported the stability of heavy oil production and the improvement of benefits and promoted the progress of development theories and technologies for heavy oil reservoirs. At present,the heavy oil reservoirs development in Shengli Oilfield is facing several problems and challenges such as poor quality of un-producing reserves,low recoveries in mature reservoirs,and large thermal recovery emissions. Technical strategies and research directions are put forward from the aspects of producing rate enhancement in new reservoirs,recovery improvement in mature reservoirs,and green and low-carbon development to provide technical support for the benefit development and green development of the heavy oil reservoirs in the Shengli Oilfield.
