This paper presents a semianalytical steady-state productivity of oil/water two-phase flow in low-permeability reservoirs with both top and bottom boundaries closed which takes the permeability stress-sensitive and threshold pressure gradient into account. Using the similar approach as Joshi’s (1988), the three-dimensional (3D) horizontal well problem is divided into two two-dimensional problems (2D), and then the corresponding nonlinear steady seepage mathematical models in vertical and horizontal planes are established. Through the separation of variables method and equivalent flow resistance principle, the productivity equation of horizontal well is obtained. The liquid and oil productivity with different influential factors are plotted, and the related effects are also analyzed. This paper expanded the conventional productivity equations of single phase into multiphase flow which have both theoretical and practical significance in predicting production behaviors in such reservoirs.

First, we researched permanent infiltrating fluid of horizontal well of the bottom water reservoir using the method of the mirror reflex ion and the potential superposition principle, so we obtained productivity formula of bottom water reservoir in the condition of monophase flow; On the basis of monophase flow, with the horizontal well productivity of monophase flow as the initial production, we deduced horizontal well productivity formula of two-phase flow of bottom water drive reservoir using the potential superposition principle and the method of equivalent filtrational resistance. This formula fit in with the field data in the practical application, therefore the theoretical study of this article has a certain guiding significance to the research and application on bottom water drive reservoir oil-water two phase flow.
