Experimental results indicate that for the polystyrene particle with a larger size, Umf changes with p-0.3, and for the sand particle with a smaller size, Umf changes with p-0.21. An empirical equation about Umf is proposed based on the experimental data: Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝ It is found that the bed expansion height increases with the increasing of gas velocity, and increases with pressure for fixed value of UUmf, when the pressure exceeds 0.7MPa, the influence of pressure on the bed expansion height is weakened.

研究结果表明，大粒径聚苯乙烯颗粒的Umf与p-0.3成比例，小粒径石英砂的Umf与p-0.21成比例，并根据实验值拟合出压力下最小流化速度公式为： Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝床层膨胀高度随气速的增大而不断增高，在相同UUmf下床层膨胀高度随压力的增大而增高，在大于0.7MPa时，压力对膨胀高度的影响减弱。

He is under pressure but we are all under pressure. I am under pressure in a different way.

"他现在饱受压力，但我们都是如此，我也承受着另一种压力。"

But the data analysis is relied on experience and statistics in a certain extent, so sometimes it makes big errors. Daniudi gas field is a low permeable gas field, the pressure buildup slowly. The measured formation static pressure is low and the flow pressure is high, so the calculated unresisted flow is high.

特别是大牛地气田属于低渗透气藏，压力恢复缓慢，所测的地层静压值偏低，求产开井3天以上多数井测取不到稳定的流压，所取流压值偏高，计算的无阻流量均偏高。

As a result , the poppet 68 is unseated and the pressure stage is transmitted through the passage 62 thus forcing the poppet 74 off of seat 72 to be dissipated in the low pressure passage 60 and the remainder of the low pressure circuit.

结果， 宝宝68 剥夺权利并且压力阶段被传送通过段落62 如此强迫宝宝74 位子72 被消散在低压段落60 和低压电路的剩下的人。

The pressure derivative curve will upwarp because of the existence of the threshold pressure gradient and the fault. The identification of the type of "upwarping" in the pressure derivative curve is crucial to the selection of the well testing model.

启动压力梯度和断层的存在都会使压力导数曲线发生"上翘"，对压力导数曲线"上翘"类型的识别，是正确选择试井解释模型的关键。
