Abstract The potential distributions and their changes with time on the surface of a cathodically protected pipe, which is put into a vessel containing sea mud, were measured experimentally and calculated with finite difference method (FDM).The calculated data are in good agreement with measured ones. Since the boundary conditions in our experimental device are the same as in systems in which the subsea pipe was cathodically protected by sacrificial anodes (SA) in the shape of bracelet, these...

Abstract The potential distributions and their changes with time on the surface of a cathodically protected pipe, which is put into a vessel containing sea mud, were measured experimentally and calculated with finite difference method (FDM).The calculated data are in good agreement with measured ones. Since the boundary conditions in our experimental device are the same as in systems in which the subsea pipe was cathodically protected by sacrificial anodes (SA) in the shape of bracelet, these results show that FDM can be used in the design and monitoring of cathodic protection systems for subsea pipelines.Considering the non-linear boundary conditions on the surface of the pipe and SA, iteration numerical method has been used in our program to obtain the calculated data. An over-relaxation method has also been used to decrease the number of iteration and to speed up the calculation. The relaxation parameter α=1 .81.

测量了并用有限差分方法(FDM)汁算了在装有海泥的槽中被保护海底管道表面的电位分布以及电位分布随保护时间的变化.计算结果与测量结果吻合得很好,这说明FDM能够应用于海底管道阴极保护电位分布计算.

n order to overcome the defects of the structure of HEGF gas generator,a piston striking device which is ignited successively was designed.This device can not only be used in multistage synchronous ignition fracturing,but also be applied in combusting fracturing ignited successively and hot ignition fracturing without seal.It can enlarge the technological scope and construction scale,improve the results of production and injection,protect casing and cement loop. This paper analysed and calculated the reliability of piston striking,safety of delaying ignition and pressure resistance of the charge's protecting pipe. Field experiments results have prove that it is applicable and very advanced.

为改进已有高能气体压裂气体发生器结构上的缺陷,设计出一种活塞自击式逐级延时引燃装置,该装置既可用于多级同步引燃压裂,又可用来逐级延时燃烧压裂和无需密封的热引燃式压裂,可扩大工艺范围及施工规模、提副曾产增注效果,并有利于套管及水泥环保护等优点.论文对活塞自击点火的可靠性、延时引燃的安全性和药柱保护管的耐压性进行了分析计算,经现场试验证明具有广泛地适用性和先进性.
