The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

With the rapid development of our country's photochemistry industry, the liquified petroleum gas is widely used. However, because of its unique flammable, explosive, virulent physic-chemical properties, it causes a series of burning, detonating accident which has occurred in domestic and foreign, which has caused the giant personnel casualty and property damage. Thus, it has been bad influence to the society. Therefore, it is necessary for the liquified petroleum gas store place to carry on the safety assessment and go on the grave accident sequential analysis research, regarding the effective science forecast, prevention and control significant accident occurrence, so it can reduce or avoid this kind of disaster accidents as far as possible, which has the important theory value and the practice significance for guarantee the liquified petroleum gas store place's safe operation.

随着我国石油化学工业的迅速发展，以及液化石油气的广泛使用，其特有的易燃、易爆、有毒的物理化学性质以及在国内外发生的一系列燃烧、爆炸等事故造成巨大的人员伤亡和财产损失，造成了不良的社会影响，因此，有必要对液化石油气储存场所进行安全评价和重大事故后果的分析研究，对于有效科学预测、预防、控制重大事故的发生，减少或尽量避免此类灾难事故的发生，确保液化石油气储存场所的安全运行，具有重要的理论价值和实践意义。

Generalizing oil-forming condition, container rock condition and preservation condition, together with analysis of evidences of oil and gas show, we can concluded that outskirts of Dayetou horseback and north-west of Zhucheng seg belong to the most beneficial region of oil and gas prospect, Chaigou horst, Jiaoxian depression and Laiyang district belong to more beneficial region, east sea area of Haiyang seg, Pingdu depression and Lidangjia structural zone belong to unaware region and land area of Haiyang seg and some intense denuded region belong to unfavorable region of oil and gas prospect.

The atomizing devices (40) can include a gas supply network and a liquid supply network that supply gas and liquid to the gas and liquid orifices (64 and 66 respectively).

雾化装置（40）可包括一气体输送网和一液体输送网，从而将气体和液体分别输送到气体和液体喷口（64和66）。

When gas superficial velocity was about equal to liquid superficial velocity, the probability density function of liquid holdup had a twin-peaked, when liquid superficial velocity was constant, one of the peaks would fade out and disappear with the in crease of gas superficial velocity. Through using the characteristics, the relative size of gas and liquid superficial velocity can be set initially.

在段塞流动中，当气相折算速度和液相折算速度相差不大时，持液率概率密度函数呈双峰分布；当液相折算速度不变时，随着气相折算速度的增大，持液率概率密度函数第2峰值逐渐减小，直至消失而变为单峰分布；利用这一特征可初步确定段塞流动中气、液相流量相对大小。
