A Study on the Lateral Accretion Body Potential Tapping of the Point Bar

Abstract:

The channel sand in PI3132 units of A area in Daqing oilfield is meandering river sand body. Although more than 90 percent of it is watering out, the serious heterogeneity in layers make it possible that there are plenty of remaining reserves in unwashed or low-washed segments in water flooded layers. All these two kinds of remaining oil are the main potential tapping objectives in later period of oilfield development.The writer deeply analyzed the point bar sand body of the meandering river, established the recognizing method of the abandoned channel and the lateral accretion body of point bar, understood the remaining oil distribution in the washed segments and unwashed segments of the thick oil layers. By implementing the Personalized treatments for individual wells,such as super-short radius horizontal wells drilling,waterflood depth profile controlling,cyclic injecting and producing, etc, the point bar sand body potential tapping technology for different formation cause has been established. And this has essential meaning to direct the oilfield development.
