Index Evaluation of Water-finding Model of Horizontal Wells in Bottom Water Reservoir
C Oilfield is a typical reservoir with strong bottom water,which is developed by horizontal well with single sand.Due to the strong bottom water capacity and the rapid rise of water cut,the biggest problem faced by oil reservoirs is the coning of bottom water.How to identify the water reach location of horizontal wells through production dynamics has practical significance for guiding produc-tion work.A new evaluation index system of water emergence mode and corresponding evaluation method are proposed.The production dynamics of horizontal wells in bottom water reservoirs is eval-uated and water emergence mode is identified by MATLAB programming.The applicability of the e-valuation method of water emergence mode under different conditions is analyzed and verified by nu-merical simulation software,which has certain guiding significance for controlling water and stabili-zing oil in bottom water reservoir.
