Using two-flow model, small perturbation theory and solvable conditions of one-order linear equations, a dispersion equation of pressure wave in horizontal air-liquid bubbly flow was proposed.
利用两流体模型、小扰动原理和线性一阶齐次方程组有解的条件，得到了气液泡状流型下的压力波色散方程。

Simulates the changes of pressure difference, velocity field and the air flow in the door opening process, and discusses the influence to the contamination dispersion.
Swelling, cracking, dispersion, migration and plugging of clay minerals are the main factors of the reservoir damage in high-pressure low-permeability reservoirs.
