The conclusions can be drawn through numerical simulation: The hydrate-forming region becomes small with increasing circulation rate and inhibiter concentration, and it is possible to make the hydrate-forming region away from sea floor by increasing circulation rate and inhibiter concentration, thus preventing blowout preventer lines from hydrate plugging; the decrease in gas volume fraction in the annulus due to hydrate formation reduces pit gain, which can delay the detection of well kick; the possibility of hydrate presence at a relatively low gas production rate is much greater than that at a relatively higher production rate; the bottom hole pressure is affected little by hydrate phase transition, and it is allowable not to consider hydrate phase transition when the bottom hole pressure is calculated; shut-in casing pressure cann't truly reflect gas kick due to hydrate formation and the situation is getting worse with time
模拟计算结果表明:溢流期间,天然气水合物的生成区域会随着循环流量的增大或抑制剂浓度的提高而减小,可通过增大流量和抑制剂浓度使水合物的生成区域脱离海底,减小防喷器管线被堵塞的危险;水合物的生成使环空中气体体积分数降低,泥浆池增量减小,给溢流检测带来延迟;当检测到有气侵发生时,水合物藏分解速率比较小时,井筒中生成水合物的可能性要比分解速率大的情况下更为严重;水合物相变对井底压力的影响较小,在工程中计算井底压力时可以忽略;由于天然气水合物的生成使得关井套压值不能真实反应气侵情况,而且随着时间的增加情况会更加严重。

But in practical operating, overvoltage caused by reignition of the vacuum switching device frequently appears, and it result in damage of the capacitor bank or the switchgear itself. Ensuring the switchgear against reignition and installing a protective device are two main approaches to avoid the phenomenon. In this paper, a study on overvoltage caused by reignition due to capacitor bank switching with the vacuum switching device and its preventive measures are carried out. The main work which has been done and researches are as follows: 1. The producing mechanism of overvoltage and its influence factor are analyzed. It is pointed out that single-phase reignition is the main reason for damage of the switchgear and two-phase reignition is the main reason for damage of the capacitor bank,so overvoltage of single-phase reignition and two-phase reignition are the emphases of prevention. 2. Analysis of the special working condition of the operating switch for capacitor bank is carried out. It indicates that the vacuum switching device is difficult to realize no-reignition under this operation condition, so it is more practical to adopt protection devices. 3. Analyses of protection effect of RC and MOA and their shortages are carried out. It shows that the two methods can only restrain effectively overvoltage caused by single-phase reignition, and they cannot protect the capacitor bank when reignition of two-phase occurs. 4. The operation principle of G-R damping device is analyzed and discussed emphatically.
本文针对真空开关投切电容器组时因重燃而产生的过电压及其防治措施进行了研究,所开展的主要工作和研究结果如下: 1、对过电压的产生机理及其影响因素进行了分析,指出单相重燃是导致开关设备损坏的主要原因,而两相重燃则是导致电容器组损坏的主要原因,因此单相重燃和两相重燃过电压是防护的重点; 2、对电容器组操作开关的特殊运行条件进行了分析,指出在这种运行条件真空开关难于实现不重燃,因此采用保护装置更具有现实意义; 3、对RC与MOA的保护效果和存在的不足进行了分析,指出这两种方法均只能有效抑制单相重燃过电压,而不能在发生两相重燃时保护电容器组; 4、重点对G-R阻尼装置的工作原理进行了分析和讨论,指出该装置接入后线路中将会出现两种频率的高频振荡,而电容器组上的过电压是由这两种振荡共同决定的; 5、根据对上述两种振荡的分析指出存在一个最佳电阻值使得过电压最低,并提出了电容器组电压和最佳电阻值的近似求解方法; 6、使用电气暂态分析软件MATLAB对G-R装置的保护效果进行了仿真计算,证实该装置确实可以有效抑制重燃时的电容器组过电压; 7、根据仿真与近似计算结果的偏差提出了近似计算的修正方法,经过修正后的过电压计算结果与仿真结果吻合较好; 8、对G-R装置中放电装置G与阻尼电阻R的要求进行了分析,指出采用编织电阻和真空间隙可能是最佳选择。

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.
对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明:1、强层化季节的陆架海水体一般呈现显著的三层热盐结构,在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层;2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制,而在潮流底边界层内,潮混合是水体热量、物质、动量与能量垂直交换的主要机制;3、潮混合影响的深度由潮流大小决定,在黄海,一般可达10-15 m,因此,在水深较深的区域,在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域,这显著抑制水体内物质的垂直通量,为物质垂直交换的瓶颈,而在水深较浅的区域,潮混合影响范围可至跃层底部,因此物质在跃层以下整个水体中混合非常均匀,当跃层内间歇性强混合发生时,可以产生显著的跨跃层物质输运;4、近底潮致强湍流耗散缓慢地向上传播,底上不同深度处垂直湍扩散系数也具有显著的位相差异,且二者均随时间呈现四分之一周日周期的变化;5、在地形较为平坦的中央海盆区,内波活动非常微弱,因此跃层内湍流混合非常弱,垂直扩散系数为分子扩散水平,跨跃层物质通量受到显著抑制,而在地形变化较为显著的局地陆坡区,内波活动非常活跃,除内潮的影响外,高频内波与内孤立波的影响也很显著,因此跃层内存在很强的间歇性强混合,内孤立波存在的区域,水体湍流混合显著增强。

The furthest along in development are the glucagon-like peptide-1 (GLP-1) drugs, which pack a triple whammy against the disease, stimulating insulin secretion, suppressing glucagon secretion, and inhibiting gastric emptying. The furthest along in its class is exenatide, a synthetic version of a GLP-1-like substance found in the saliva of the Gila monster. An open-label study reported at the meeting showed that about half of patients failing oral therapy achieved near-normal glycemic control when exenatide was added to their regimen.
