Determination of the proved reserves area of low permeability reservoirs in Daqing Oilfield
Online published: 2007-12-15
Based on the analysis of distribution characteristics of proved reserves of low abundance reservoirs in Daqing peripheral oilfield, the main principles and methods for determining oil-bearing area of proved reserves of low permeability reservoirs in northern Songliao Basin are summarized. According to the change of area after the exploitation in typical blocks, the influence of wells per square kilometer on the determination of oil-bearing area is analyzed. The quantity of drilling wells per square kilometer is considered to be controlled by the size and shape of sand and the type of reservoir in northern Songliao Basin. It should be increased to 0.5 to 1.0 per square kilometer in the evaluation stage for lithologic reservoirs.
