Evaluation of water control and oil stabilization capability of horizontal wells and study on adjustment strategies in Bohai S Oilfield
摘要
Abstract
As integrated well pattern development areas of Bohai S oilfield enter the high water cut period,issues such as increased decline rates and accelerated water cut rise become prominent,making water control and oil stabilization more challenging.Currently,there is a lack of methods to evaluate the water control and oil stabilization capability of oil wells,resulting in the inability to adopt targeted treatment strategies.To address this issue,mathematical methods and seepage theory were employed to propose the production dynamic characteristic value and channeling index for evaluating water control and oil stabilization capability.Based on the evaluation of water control and oil stabilization effectiveness,the concept of dimensionless swept area was introduced to characterize the planar displacement efficiency of integrated well patterns under different adjustment strategies,thereby theoretically determining reasonable adjustment strategies for the injection-production system.These results were applied to Block G of S Oilfield,where the natural decline rate decreased by 4.0%compared with the previous year and annual oil production increased by 1.9×104 m3,achieving favorable adjustment outcomes.The research results provide guidance for evaluating water control and oil stabilization capability and formulating adjustment strategies for integrated well patterns.关键词
