Abstract:

 Daqing Oilfield, as the biggest petroleum production base in China, its total production of crude oil accounts for over 40％ of the total production of the mainland in the same period, and its development situation directly influences the supply of the national crude oil. In recent years, because the production of Daqing Oilfield gradually decreases and the domestic energy supply falls short, the increasing speed of oil and gas resources quantity draws the attention of the public. According to the situation and based on the collection of great quantities of original data in Daqing Oilfield and in combination with the characteristics of Daqing Oilfield, this article adopts the prediction method for the growth of reserves to make an estimate of the new recoverable reserves in Daqing Oilfield. The result shows that the new added resource quantity in Daqing Oilfield presents a downward trend, and the time of finally recoverable reserves will be 2028. The article also analyzes the main controlling factors in the changing of new added oil and gas resources from international and domestic respects, and draws a conclusion that the fluctuation of international crude oil price and the domestic policy guidelines and technology progress are the main causes that influence the new added oil and gas resources in Daqing Oilfield.
