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。

The seasonal division and their change in various Sichuan areas is discussed using the daily mean temperature data of Sichuan 135 stations and the seasonal division method by Zeng Qingcun et al. It is shown that:(1) Between 1961-2004 each seasonal length is different, summer and winter are longer than spring and autumn, and difference of the seasonal division in different areas is mainly shown by the time scale of spring and autumn.

The study of vertical channel with high field effect mobility by Ni induced lateral crystallization, which can form larger grains on channel regions and reduce grain boundary defects. We detect the method of Ni induced lateral crystallization through high field effective mobility, but that accumulates too much Ni on floating N+ region and causes defects and metal contamination. As Ni is used to form silicde and then proceed to low temperature annealing, we can observe the floating region that has no Ni acumination regions or contaminations. This aids us in obtaining good electronic performance of this device, not only the remote field effective mobility but also the vast improvement of sub-threshold swing and on/off currents.
接著,是延续垂直通道的研究,希望能有效的提升电子迁移率,因此以镍金属诱导横向结晶的方式使通道形成较大的结晶,减少矽晶粒之间的缺陷,而在初步的研究,发现以镍金属直接诱导横向结晶的方式,经由低温长时间回火之后,由於镍金属扩散的关系,完成诱导结晶之后,有过多的镍金属聚集在顶部参杂的中间区域,而造成过多的缺陷累积,虽然电子迁移率有效的提升,但整体的电性并不如预期,因此提出先形成镍金属矽化物后,将未反应的镍金属或金属氧化物去除之后,再进行镍金属矽化物诱导横向结晶处理,经由结果观察得知在顶部掺杂区域部分没有明显的镍金属累积或污染,并且得到很好的整体电性,除了电子迁移率有效提升之外,次临界特性以及导通电流都能有效改善。
