As Gulong shale oil is a typical continental shale oil, the oil is rich in foliation cracks and matrix pores, with fine lithology and clay mineral content above 35%. It was previously considered as a rock with extremely low porosity and poor permeability, and it was basically impossible to store oil. Gulong shale oil is a brand-new field of oil and gas exploration and development, which is widely developed nationwide and has broad exploration and development prospects.

After 62 years of high-speed and efficient exploration and development in Daqing Oilfield, conventional oil and gas resources have entered the middle and late stage of discovery, which is difficult to support long-term sustained and stable production.

The successful practice of Gulong shale oil indicates that Songliao basin has entered an unconventional era and is an important material basis for long-term stable production in Daqing Oilfield.
