Establishment of inflow performance relationship of horizontal wells in low-permeability reservoir;

Study on characteristics of horizontal well inflow performance considering variable mass flow in solution gas drive reservoirs

Condensate dropout is widely existent in development of condensate gas pool, usually different from gas inflow performance.

The key problem of producing nodal analysis for gas-water well is analysis of inflow performance of the gas -water well.

THE PREDICTION OF FUTURE IPR OF VERTICAL WELLS IN LOW PERMEABILITY RESERVOIRS;

Based on the non-Darcy percolation theory in low permeability reservoir and analysis of the function Kro/Boμ,a dimensionless IPR equation for damaging well in low permeability reservoir both under saturated and unsaturated states is derived.

Base on the theory of non-Darcy flow and deformed media percolation in the low permeability reservoir and the analysis of the shape of Kro/(Boμ) function,a universal dimensionless IPR equation is derived for saturated and undersaturated linear deformation low permeability oil reservoirs.

Evaluation on inflow performance relationship of gas wells in pressure-sensitive reservoir using generalized pseudo pressure;

Research on inflow performance relationship of oil - gas -water three phases for horizontal wells;

The functional relation of flowing coefficient with flowing pressure was described as a parabolic function,and a new type of inflow performance relationship which contained 3 undetermined coefficients was setup.
