封堵调剖实验表明，泡沫复合驱具有优良的封堵调剖能力，其封堵能力随渗透率增加而增大；气液共注时，阻力因子随注入量增加而持续增大，交替式注入时，阻力因子随注入量的增加波动上升，但随着注入量不断增加，两种方式均能产生较好的封堵效果；低气液比交替注入时，封堵作用表现缓慢；大段塞交替注入时，封堵效果相对较弱。

Box in the settings: melting Plug and plug, air switches, light switches, low-voltage lamps, power supplies, single phase power supply, etc.?

电箱边撤销：熔塞及熔塞座、不满气开关、照明开关、低不抬灯、电源、单相电源等。

Based on the characteristics of casing annulus gas-venting wells, the particularity of multi-phase flow in the condition that the casing-head gas flows through a nearly stagnant liquid was investigated. Based on the theory of Taylor bubble, a model to calculate void fraction and pressure gradient in various viscosity liquids was developed. This model is applicable to bubbly flow and slug flow.

以泰勒气泡在黏滞流体中的上升流速作为主要依据，建立了不同油黏度下套管环空放气流动的截面含气率和压降计算模型，并提出了不同黏度、不同气油比的套管定压放气井环空流动计算及套管压力分布的多相流模型，该模型主要适用于泡流和段塞流。

The finger type slug catcher is one of the important equipments at the terminal of the wet gas transmission pipelines. Its design parameters are so complicated that China still has not produced this product with independent intellectual property rights.

管式液塞捕集器是气液混输管线终端的重要设备，其设计参数复杂，目前国内还没有具有独立知识产权的液塞捕集器产品。

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.

对水为连续相的5种流型VMEA传感器波动信号进行了多尺度熵分析，研究结果表明：含油率增加可使水包油段塞流在较低气相表观速度下产生；较低流速下的油水相态逆转可发生在油液比为0.9左右，气相流速增加使得逆转点向含油率低的方向偏移；多尺度熵细节可以刻画油气水三相流非线性动力学特性，而低尺度的多尺度熵变化率敏感地反映流型转变，是划分油气水三相流流型的有效准则。

Also, because oil-absorbing tube 6 in the role of one-way valve 7, compressed air will not flow backward into the oil pipe from the oil-absorbing cup, so we can keep gas in a state of the oil gagged refueling, refueling is completed, screw plug oiling .

又由于吸油管6中单向阀7的作用，压缩空气也不会从吸油管倒灌到油杯中，所以就可以在不停气的状态下向油塞口加油，加油完毕，拧上油塞。

Open water before the gas plug screw, and then adding water until the run out from the pore water release, and then a few rotating shaft, such as to continue to take water that has been filled with water, and then close the gas plug, ready to start.

灌水前拧开放气螺塞，然后加水，直到从放气孔向外冒水，再转动几下泵轴，如继续冒水，表明水已充满，然后关闭放气螺塞，准备起动。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
