Abstract

In order to reduce the loss caused due to the scaling in the heat injection generators for the oil production in oilfield, a simulating wet steam generator was designed to simulate the process of wet stream generation for the purpose of studying the scaling in the generators. The XRD, EPMA, and SEM were employed to study the scale formed on the inner surface of pipes in generators through the simulating steam injection system. The results show that the scale distributed in the radiant heating pipes is mainly composed of montmorillonite, pectolite and acmite. These three minerals were formed under the similar hydrothermal condition. The XRD studies show that the scale of montmorillonite and pectolite is distributed throughout on the inner surfaces of whole pipes, but the scale of acmite is mainly distributed on the inner surfaces of the end of radiant heating pipes. It is believed that the Fe for forming acmite is mainly from the erosion of pipes with minor Fe from the trace Fe in water.
