Study on Environment Friendly Descaling and Formation Unblocking Technique for Injection Wells
Petroleum Engineering Research Institute of Dagang Oilfield, Tianjin 300280
Corrosion and scale formation of near well-bore zone are common reasons that affect the effectiveness of injection wells. Although conventional stimulation treatments can remove the blockage, many disadvantages occur such as short-term effectiveness, long occupation period, large amount of waste fluid, big environmental impact and limited transportation procurement. In this paper, an environment friendly descaling and formation unblocking technique was found which includes two kinds of treatments. One is called neutral descaling, anti-swelling, liquid circulation cleaning technique(NALC) and the other is called slow release anti-scaling solid acid treatment(SASA). The environment impacts of well stimulation treatments are significantly reduced which would meet the requirements of the “Green Mine” needs.
