从流体封存箱的基本概念出发，研究了在高温、高压、封闭地层这一特定地质条件下，产生脉冲式混相涌流这种特殊的天然气运移方式。其原理是：随着异常高压的不断增加，高压带边缘（封存箱顶、底面或侧面）的相对封隔带发生破裂，高压带内的流体———溶解气、水、游离气、油等以混相方式向外涌出；随着压力的下降，油、气、水三相分离，溶解于地层水中的天然气会大量析出，游离气相大量增加；当高压带流体压力得到释放后，破裂的岩层重新闭合而成为新的相对封隔层，当压力再次升高时，又重复上述过程，呈脉冲状周而复始。据此，以莺歌海盆地为实例，分析了其封存箱分布及天然气运聚成藏特征，建立了典型的模式。最后认为，脉冲式混相涌流是天然气成藏的一种特殊的运移方式
Based on the basic concept of fluid storage tank, this paper studies the special natural gas migration mode that produces pulsed mixed inrush under the specific geological conditions of high temperature, high pressure and closed formation. The principle is: As the abnormal high pressure continues to increase, the pressure belt edge (the top, bottom or side of the package box) of the relative seal rupture, high-pressure zone of the fluid --- dissolved gas, water, free gas, oil, etc. With the pressure drop, oil, gas and water three phase separation, dissolved in formation water will be a large number of natural gas precipitation, a substantial increase in free gas phase; when the high pressure fluid pressure is released, the rupture of the rock Closed again as a new relative confinement layer, when the pressure rises again, repeat the above process, was pulsing weeks and again. Based on this, taking the Yinggehai Basin as an example, the characteristics of its storage box and the characteristics of gas migration and accumulation are analyzed and a typical model is established. Finally, it is considered that the pulsed mixed inrush current is a special migration mode of natural gas accumulation
