Every wind up full the clock can work 7 days, this time the hammer drop at the bottom, Need wind up once again, to the hammer rise again.

But in practical application, the results of calculation usually have a greater difference from reality, which are mainly the following several points: it is thought that single-phase to flow for fluid in the formula, and multiphase flow exists actually; also the impact of the pressure drop in horizontal section and the wellhole completion forms on the deliverability are not included, as well as the bottom water coning is a complex question affecting well deliverability.

但在实际应用中，计算结果与实际往往存在较大的差别，其原因是：公式推导中假设流体流动是单相流动，而实际地层往往是油水两相流动；公式中没有考虑水平井筒内压降的影响；不同的完井方式所对应的表皮系数不同，对产能影响也较大。

A hypothetical drained cell model retrofitted from a 160kA Hall-Heroult cell was set up to calculate the current distribution in the cathode when the anode bottom and cathode top surfaces were declivous. Two half anode-cathode slice thermo-electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode.

摘 要：将某厂现有的160kA Hall-Heroult铝电解槽改造成导流槽后，在阴极上表面和阳极底面呈斜坡状的条件下，计算了采用不同阴极导杆安装方式时阴极的电位和电流分布，即通过建立导流槽内部从阳极到阴极的一个半切片电热场模型，用有限元法分别对水平和平行于阴极斜坡两种不同导流槽阴极导杆的安装方式下阴极电位和表面电流密度分布进行了计算。

Considering gas-solid flow in annular space and BoYun Guo's hydrodynamic parameters model, For aired underbalanced drilling, combined with the minimum energy Angel law and based on the mininum gas injection scale at the key points, it is established a bottom-hole pressure model for gas-solid two phase stream; meanwhile, calculated the downhole depth of the Downhole-Deployment-Valves; and then fabricated the corresponding calculation software. For streamingly underbalanced drilling, it is fully given a step-by-step solution based on analysis from the relationship of various wellbore pressures at the course of underbalanced drilling as well as from the streaming behavior in different wellbore sections, adding consideration on multiphase stream pressure drop and Downhole-Deployment- Valve into account, it is of common application for development wells.

对于气体欠平衡钻井，考虑环空为气固两相流，参考BoYun Guo的流体力学参数计算模型，结合Angel的最小动能法标准，从满足关键点处的最小注气量入手，建立了气固两相流的井底压力计算模型，同时对套管阀的下入深度进行了计算，并利用VB语言编制了相应的计算软件；对于液体欠平衡钻井，考虑环空为多相流，在充分分析欠平衡钻井井内基本压力关系的基础上，从环空多相流压降分析入手，通过对井筒内各段的流态分析，逐段求解。
