The results show that the combination effect of temperature and corrosive gas contributes to the intergranular corrosion, thereafter, leading to the occurrence of the crack of the pole thread. 结果表明,极丝在温度和腐蚀性烟气的共同作用下,产生了晶间腐蚀,因而产生早期断裂。
As oil and gas contains certain amount of hydrogen sulfides, the processing plant facility is subject to severe corrosion, which imposes a great thread to the safe operation of the oil& gas field. 由于油气中含有一定量的硫化物,使得联合站的生产装置硫化氢腐蚀的问题十分突出,威胁油气田的安全生产。
Incandescent mantle gas, whether or not containing asbestos thread, fitted with supports, finished, of impregnated with chemicals 白炽煤气灯罩,不论是否含石棉线、装有支架、经整饰或用化学品浸渍
On the basis of the analysis of oil and gas pool-forming condition, the evolution of fluid dynamic is considered as the main research thread and the stage of oil and gas accumulation and leakage is discussed, especially the oil and gas accumulation in the latest stage. 以盆地的形成演化为背景,在油气赋存条件研究的基础上,以流体动力演化历史为主线,探讨油气动态聚、散的期次和特点,突出最晚主要聚集期的成藏作用;
