initial setting

List the semi-submerged platform and drill-ship that equipped dual derrick, also the main form of dual derrick. Select the proper topology structure and finish initial setting of parameters.

列出双井架平台和钻井船和使用双井架主要的结构形式，选择合适的井架拓扑结构。对双井架使用状况分析，完成井架参数的初步设定。

The starting time of setting stage is identical with initial setting time. However, the ending time of setting stage lags behind the final setting time.

通过比较凝结期起止时间和实测的凝结时间，发现凝结期开始时间与初凝时间非常吻合，而凝结期终止时间则明显滞后于终凝时间。

Through adding 1% oxyful to oxygenize the calcium sulfite, when the dosage of FGD gypsum is 5%, compared with the gypsum without oxyful, initial setting time prolongs 5.9%, final setting time prolongs 12.5%.

加入1%双氧水氧化脱硫石膏中的亚硫酸钙，与未添加双氧水的水泥凝结时间相比较，5%掺量时，初凝时间延长5.9%，终凝时间延长12.5%。

Properties of the slag can be adjusted and initial setting time can be adjusted discretionarily according to the requirements of design and engineering;

性能易调节，初终凝时间可根据设计和施工要求任意调整；
