还注采舌进图一个理论基础

运用平面稳态流速场运动学通式,经过＂求逆,求导,求积＂3步运算,获得了无限大等厚均质水平地层内等流量一注一采两口铅垂井激发的渗流场内流体质点的运动学方程。根据所得方程,首次从理论上成功地绘制了注采舌进图,填补了现行油气渗流力学教科书中的理论空白。该通式还可用于求解铅垂井群或裂缝群注采相关的运动学问题,因而可作为水驱油技术的重要理论基础。

Theoretical Basis of Injection-Production Tonguing Animation

By the general kinematic formula for steady flow velocity field and the three procedures of＂inversion, derivation, and integration＂, the kinematics equation was easily obtained of fluid particles in velocity field excited by two vertical wells of injection andproduction with equivalent flow in the infinite, isopachous and homogeneous horizontal strata. Based on the equation, an injectionproduction tonguing animation was successfully drawn on a theoretical basis for the first time. It fills the theoretical gap on mechanics of fluids in porous media. This general formula can also be applied to the solutions of kinematics problems related to the injection and production of a vertical well group or a fracture group. Therefore, it is an important the oretical basis for water flooding.
