In the first 10 months, the natural decline rate of thin oil production in Gudong oil production plant of Shengli Oilfield was 8.2%, which was the lowest natural decline rate of thin oil production in Shengli Oilfield, decreasing by 4 percentage points year-on-year.

The exploration area of Gudong oilfield is small, only 118 square kilometers, the exploration and development degree is high, the recovery rate is 43.6%, the recovery degree is 41.7%. How to reduce the natural decline rate and improve the production efficiency of Gudong oilfield, which has been developed at a high speed for 37 years, is a difficult problem facing the cadres and employees of Gudong Oil production plant.

Since this year, Gudong oil production plant has been focusing on the goal of energy adjustment, water cut reduction and decline control, and has analyzed the reservoir condition, development law, development status and process adaptability, and played a "combination punch" to achieve production increase.
