中文摘要：
设计的基础气化钻是在 wellbore 理解气体 / 液体的二阶段的流动的行为。质量和动量保存的方程和在多孔的媒介的液体流动的方程被用来建立一个动态模型在煤气液体的二阶段的流动上根据 Ansari 和 Beggs 鲽鱼的学习结果预言 wellbore 压力。动态模型被与机械学的稳定的州的模型相结合的有限差别途径解决。机械学的动态模型数字地被实现进一个 FORTRAN 90 计算机节目并且能在 wellbore 和水库模仿液体的联合流动。动态模型表明水源的效果在 bottomhole 压力上支持压力和气体 / 液体的注射率。模型对照原尺寸的试验性的数据被验证，并且它的 5.0% 平均相对错误能在设计设计满足精确性要求。
英文摘要：
The basis of designing gasified drilling is to understand the behavior of gas/liquid two-phase flow in the wellbore. The equations of mass and momentum conservation and equation of fluid flow in porous media were used to establish a dynamic model to predict wellbore pressure according to the study results of Ansari and Beggs-Brill on gas-liquid two-phase flow. The dynamic model was solved by the finite difference approach combined with the mechanistic steady state model. The mechanistic dynamic model was numerically implemented into a FORTRAN 90 computer program and could simulate the coupled flow of fluid in wellbore and reservoir. The dynamic model revealed the effects of wellhead back pressure and injection rate of gas/liquid on bottomhole pressure. The model was validated against full-scale experimental data, and its 5.0% of average relative error could satisfy the accuracy requirements in engineering design.
