断块油藏水平井产能研究及断层封堵影响分析
摘要
Abstract
Productivity evaluation for horizontal well of faulted block reservoirs is difficult due to the impact of fault. On the basis of the image method, the semi-analytical models of steady productivity prediction is established under the coupling of the horizontal wellbore and reservoir. The quantitative analysis of the fault sealing impact is also conducted. The error calculated by the model is between ±15% which could be accepted in field application. It is an effective method for the productivity evaluation of horizontal wells in faulted block reservoirs. If the distance between the fault and the horizontal well is the range of 4.5 times of the horizontal section length, the productivity of the horizontal increases with the distance increasing. Else if the distance is more than 4.5 times of the horizontal section length, the fault sealing impact decreases with the distance increasing.关键词
