Production Dynamic Method to Determine the Critical Production of Bottom Water Reservoir

Abstract:

Tahe oilfield of Triassic oil under low amplitude anticline group monolithic sandstone reservoirs with bottom water features, having a uniform oil-water interface, water energy sufficient. The current production wells generally see water, water cut rising too fast. Horizontal well bottom water coning phenomenon is outstanding, later period of high water cut stage manages difficulty to increase, water blocking measures have a low efficiency. Determine critical output, to improve production well life, efficient development reservoir has important significance .Based on the study of dynamic characteristics of single well and geological analysis of factors determining the critical output, and the application of numerical simulation method to verify the reasonable threshold quantity production. This method is simple and practical, can accurately make the critical output of single well.
