油井流入动态方程理论研究及应用

通过对K_roB_oμ_o,函数形态的分析,确立了其与压力的一般性函数关系式,并由此得到了饱和油藏和未饱和油藏的油井流入动态方程及其通式。这些方程在一定条件下,不仅可转化为经典的Vogel方程和Fetkovich方程,而且也可转化为推广的Vogel方程,因此很具理论性和通用性。经实际油田应用,效果很好,值得推广。

Theoretical Study and Application of Well Inflow Performance Relationships

This paper analyzes the K_roB_oμ_o function form, establishes its general functional relations to pressure, from which obtains the well inflow performance equations and general formula in saturated and unsaturated reservoirs. These equations can either be inverted into classical Vogel and Fetkovich equations or into generalized Vogel one under some condition. Their theoretical and universal properties are demonstrated in oilfeld application study, and the results are reliable and good for popularization.
