尽管杜依玛兹油气分配管理局对油矿设备和管线的防腐作了大量综合性工作,但设备和管线的破坏仍在增加,特别是处理、输送、注入污水的油矿管线(见下表)。由于管线经常穿孔,造成大量污水的漏失,污染了耕地、森林和水池,同时修理和更换管线的费用也增加了。因用于注水的各种水的物理一化学特性不同,所以需要按不同的途径来解决设备的腐蚀问题。在300口注水井中用水量为11万米~3/日,其中7.5万米~3—属于泥盆纪氯化钙型水,
Although the Duimasi Oil and Gas Administration has done a great deal of comprehensive work on the preservation of oil equipment and pipelines, the destruction of equipment and pipelines is still increasing, especially in oil pipelines handling, transporting and injecting wastewater (see table below). Due to the frequent perforation of pipelines, large amounts of sewage are lost, contaminated farmland, forests and ponds, and the costs of repairing and replacing pipelines also increase. Due to the different physical and chemical characteristics of the various water used for water injection, the corrosion of the equipment needs to be solved in different ways. 300 water injection wells in the water consumption of 110,000 m ~ 3 / day, of which 75,000 m ~ 3 are Devonian calcium chloride-based water,
