Study on the Adaptability Limits of Point Bar Potential Tapping by Horizontal Well at High Water Cut Stage
摘要
Abstract
Combined with geological and production performance data in 4 sand group of upper Ng in Gudao Oilfield,the three-dimensional typical model reflecting reservoir architecture of point bar is set up according to quantitative description of lateral accretion interbed in point bar. Based on economic limit production of horizontal well,the methods of reservoir engineering and numerical simulation are used to analyze the adaptability limits of point bar potential tapping by horizontal well at high water cut stage on the basis of distribution modes of remaining oil under different injection-production patterns in point bar. The result shows that when the dip direction of interbed is consistent with water injection,and permeability of interbed is less than 12 mD,dip angle is lower than 7°vertical extension length/reservoir thickness more than 0.46 and horizontal spacing less than 60 m,it is time to prepare for tapping the potential of horizontal wells. When the dip direction of interbed is opposite to water injection,and the adaptability limits become 30 mD,11°,0.33 and 90 m respectively,it is time to carry out potential tapping. Such results provide a certain theoretical guidance for application of horizontal wells in point bar at high water cut stage.关键词
